How are we here? He was just a tiny baby not too long ago. If you\u2019ve been around here for any amount of time, you know my boys are obsessed with all things cars, trucks, and construction. This Hot Wheels cake is the perfect cake for little racers.<\/p>\n\n\n\n<p>My boys have birthdays just a few weeks apart, and so this year the birthday themes were<a href=\"https:\/\/beyondfrosting.com\/monster-jam-gravedigger-cake\/\" data-wpel-link=\"internal\" rel=\"follow\"> Monster Jam<\/a> and Hot Wheels. I must say this has been my favorite year for cakes! In years past, we\u2019ve done <a href=\"https:\/\/beyondfrosting.com\/construction-cake\/\" data-wpel-link=\"internal\" rel=\"follow\">construction cakes<\/a> (with matching <a href=\"https:\/\/beyondfrosting.com\/construction-themed-party-favors\/\" data-wpel-link=\"internal\" rel=\"follow\">party favors<\/a>) and even a <a href=\"https:\/\/beyondfrosting.com\/rubble-paw-patrol-cake\/\" data-wpel-link=\"internal\" rel=\"follow\">Paw Patrol cake<\/a>.\u00a0<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Things to Know About This Hot Wheels Themed Birthday Cake<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>100% homemade. <\/strong>This is a 3-layer 6-inch cake made with a variation of my <a href=\"https:\/\/beyondfrosting.com\/super-moist-chocolate-cake\/\" data-wpel-link=\"internal\" rel=\"follow\">chocolate cake<\/a> as the base and decorated with <a href=\"https:\/\/beyondfrosting.com\/perfect-vanilla-frosting\/\" data-wpel-link=\"internal\" rel=\"follow\">vanilla buttercream<\/a>.<\/li>\n\n\n\n<li><strong>Thick chocolate layers. <\/strong>This cake recipe yields a thicker cake with a tighter crumb, yet it\u2019s still incredibly moist and spongy. You\u2019ll want the thicker cake layer to accommodate the tunnel in the cake.\u00a0<\/li>\n\n\n\n<li><strong>Some skills are required. <\/strong>Bakery cakes can be expensive, and I had so much fun (and a bit of stress) making this Hot Wheels birthday cake from scratch. It takes time and a little bit of skill, but you can apply the frosting, fondant, and decorating techniques to future birthday cakes, too. You\u2019ll notice some flaws in my cake, I am embracing them. You will learn from my mistakes!<\/li>\n\n\n\n<li><strong>Make it your own. <\/strong>I set out to make a Hot Wheels cake with a tunnel for toy cars running through the bottom cake layer. Ambitious, but it paid off! If you don\u2019t feel like making the tunnel, you can simply skip that step and assemble the layer cake as usual, but I have to say it was such a HUGE hit with his friends. <\/li>\n\n\n\n<li><strong>Consider how to store and transport.<\/strong> My cake carrier was JUST tall enough to keep the cake stored airtight without the decorations. I transported it in the cak carrier and assembled onsite where we were having the party.<\/li>\n<\/ul>\n<\/div>\n\n\n<div id=\"callout-box-block_ef5792c02602f98fceb63055302034c1\" class=\"callout-box-block callout-box-style-1\"><p><h2 class=\"callout-box-title\">Picking A Track<\/h2><\/p><div class=\"callout-box-content\"><p>As you\u2019re planning your cake, pick a simple track, and know what size table you will need to support it. Mine was a continuous loop with a motor running. EVERY kid at the party wanted to send a truck through the cake. As I anticipated that, I decided I would serve cupcakes so they could enjoy the love and labor that went into the cake (don\u2019t worry we served it at home!).<\/p>\n<\/div><\/div>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake - Hot Wheels Birthday Cake Tutorial!\" alt=\"An angled view of a Hot Wheels cake showing a toy car coming through the tunnel that runs through the cake.\" class=\"wp-image-64776\" title=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" srcset=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409.jpg 1200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-200x300.jpg 200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-427x640.jpg 427w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-768x1152.jpg 768w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-1024x1536.jpg 1024w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-250x375.jpg 250w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-350x525.jpg 350w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-500x750.jpg 500w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-800x1200.jpg 800w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-900x1350.jpg 900w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-150x225.jpg 150w\" data-lazy-sizes=\"(max-width: 1200px) 100vw, 1200px\" data-pin-media=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409.jpg\" src=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409.jpg\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake - Hot Wheels Birthday Cake Tutorial!\" src=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409.jpg\" alt=\"An angled view of a Hot Wheels cake showing a toy car coming through the tunnel that runs through the cake.\" class=\"wp-image-64776\" title=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" srcset=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409.jpg 1200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-200x300.jpg 200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-427x640.jpg 427w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-768x1152.jpg 768w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-1024x1536.jpg 1024w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-250x375.jpg 250w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-350x525.jpg 350w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-500x750.jpg 500w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-800x1200.jpg 800w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-900x1350.jpg 900w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409-150x225.jpg 150w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" data-pin-media=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8409.jpg\"\/><\/figure>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Prepare the Buttercream<\/h2>\n\n\n\n<p>First, prepare the buttercream frosting you\u2019ll use to fill and frost your Hot Wheels birthday cake. <strong>Refer to the printable recipe card for the full recipe amounts and detailed instructions.<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Make the frosting.<\/strong> Beat cold butter for 5-10 minutes until it\u2019s whipped and super fluffy.

Grab a package of pre-colored fondant at craft stores like\u00a0 <a href=\"https:\/\/rstyle.me\/+Fzrps_8eUQO37dG7Ja5hJA\" data-wpel-link=\"external\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Michaels<\/a>, <a href=\"https:\/\/www.hobbylobby.com\/party-baking\/baking-supplies\/fondant-icing\/yellow-vanilla-fondant\/p\/150640\" data-wpel-link=\"external\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Hobby Lobby<\/a>, or <a href=\"https:\/\/walmrt.us\/420n4nd\" data-wpel-link=\"external\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Walmart<\/a>. <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\">Checkered Flag Pattern<\/h3>\n\n\n\n<p>You\u2019ll need less than 4 ounces of fondant for the squares. You can cut your fondant squares up to 48 hours ahead of time. If you do, arrange them in a single layer in an airtight container to store for later. Cutting out the squares is easy:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Roll out the fondant.<\/strong> Use a <a href=\"https:\/\/amzn.to\/3RatjA9\" rel=\"sponsored nofollow noopener noreferrer\" target=\"_blank\" data-wpel-link=\"external\">fondant roller<\/a> or rolling pin to roll out each color to an even \u215b\u201d thickness.<\/li>\n\n\n\n<li><strong>Cut out the squares.<\/strong> Next, use a small <a href=\"https:\/\/amzn.to\/4iYyQW8\" rel=\"sponsored nofollow noopener noreferrer\" target=\"_blank\" data-wpel-link=\"external\">square cookie cutter<\/a> to cut out squares in each color. The cutter I used is \u215d\u201d. Alternatively, you can use a ruler and pizza cutter to measure and cut\u00a0 (I\u2019ve also seen <a href=\"https:\/\/amzn.to\/42emfbP\" rel=\"sponsored nofollow noopener noreferrer\" target=\"_blank\" data-wpel-link=\"external\">plunger cutters<\/a> and <a href=\"https:\/\/amzn.to\/4kYjKlf\" rel=\"sponsored nofollow noopener noreferrer\" target=\"_blank\" data-wpel-link=\"external\">multi-cutter squares<\/a>, but I have not personally used them). You\u2019ll need approximately 40 squares of each color, depending on how much decoration you want to do.<\/li>\n<\/ol>\n\n\n\n<p>It\u2019s best to apply the fondant squares to the cake when the buttercream is fresh. If you\u2019ve already frosted the cake and are applying the squares later, use a toothpick to gently scratch the buttercream before you place the fondant on top. This helps it adhere to the cake. Or you can use piping gel.<\/p>\n\n\n\n<p>I opted to make a few different arrangements of the checkered pattern, taking inspiration from various cakes I\u2019ve seen online.

Consider picking up an extra 4-ounce package of fondant. I had issues with cracking while making mine, and the one pictured on the cake is actually cracked on the bottom. I covered it with a car!<\/p>\n<p><strong>Shaping: <\/strong>You\u2019ll need a round object to shape the mold. Make sure to place some parchment under the fondant so it doesn\u2019t stick to your round object.<\/p>\n<p><strong>Allot enough time: <\/strong>It needs several days to dry, take that into consideration as well as how to transport it. It\u2019s very fragile.<\/p>\n<\/div><\/div>\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\">Orange Fondant Loop<\/h3>\n\n\n\n<p>The fondant loop that I made as a cake topper took several days to dry, so give it plenty of time. The fondant should be thick enough so it (hopefully) won\u2019t crack, but still thin enough so it dries completely.\u00a0<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Roll out and cut the fondant. <\/strong>I recommend planning your loop using a piece of actual Hot Wheels track. This way, it\u2019s roughly the same width and you can trim the excess off the sides. Roll out the orange fondant to \u215b\u201d thick, and using the track as a guide, trim the edges with a pizza cutter or knife. Make the strip longer than you think you need at first, as you can always trim it back.<\/li>\n\n\n\n<li><strong>Shape the loop.<\/strong> To make the loop, use a wide cup or cylinder covered with a piece of parchment paper. Loop the fondant around the cylinder with the parchment paper in between, and place it on a sheet pan lined with parchment paper. Trim the ends as needed. Finally, place the fondant loop in a cool, dry place for several days to dry.\u00a0<\/li>\n\n\n\n<li><strong>Decorate. <\/strong>To place it on the cake, consider using a large spatula or cake lifter. I transported it in a separate container and placed it after my track was attached and assembled.<\/li>\n<\/ol>\n<\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake -

I piped the frosting with a large French star tip following the same method as my <a href=\"https:\/\/beyondfrosting.com\/rainbow-cupcakes\/\" data-wpel-link=\"internal\" rel=\"follow\">rainbow cupcakes<\/a>. Afterward, I topped each cupcake with a chocolate tire (see below). For the flames coming out of the chocolate tires, I used leftover orange buttercream and a size 21 tip.<\/p>\n<\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake - Hot Wheels Birthday Cake Tutorial!\" alt=\"A Hot Wheels themed cupcake topped with colorful frosting, a chocolate tire, and a mini racing flag inside a cupcake liner with a checkered pattern.\" class=\"wp-image-64783\" title=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" srcset=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477.jpg 1200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-200x300.jpg 200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-427x640.jpg 427w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-768x1152.jpg 768w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-1024x1536.jpg 1024w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-250x375.jpg 250w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-350x525.jpg 350w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-500x750.jpg 500w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-800x1200.jpg 800w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-900x1350.jpg 900w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-150x225.jpg 150w\" data-lazy-sizes=\"(max-width: 1200px) 100vw, 1200px\" data-pin-media=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477.jpg\" src=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477.jpg\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake - Hot Wheels Birthday Cake Tutorial!\" src=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477.jpg\" alt=\"A Hot Wheels themed cupcake topped with colorful frosting, a chocolate tire, and a mini racing flag inside a cupcake liner with a checkered pattern.\" class=\"wp-image-64783\" title=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" srcset=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477.jpg 1200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-200x300.jpg 200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-427x640.jpg 427w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-768x1152.jpg 768w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-1024x1536.jpg 1024w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-250x375.jpg 250w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-350x525.jpg 350w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-500x750.jpg 500w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-800x1200.jpg 800w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-900x1350.jpg 900w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477-150x225.jpg 150w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" data-pin-media=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8477.jpg\"\/><\/figure>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h3 class=\"wp-block-heading\">Chocolate Tires<\/h3>\n\n\n\n<p>I topped my cake and cupcakes with edible tires. You can make these with black fondant or melted chocolate. Since I was serving them to the kids, I opted for chocolate tires. I used these <a href=\"https:\/\/amzn.to\/3Rm5Xax\" rel=\"sponsored nofollow noopener noreferrer\" target=\"_blank\" data-wpel-link=\"external\">tire molds<\/a> from Amazon. I found the two medium-sized tires, although they\u2019re different patterns, worked best.\u00a0<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Prepare the chocolate.<\/strong> To make the chocolate tires, I used my <a href=\"https:\/\/amzn.to\/3CF9pt3\" target=\"_blank\" rel=\"noopener sponsored nofollow noreferrer\" data-wpel-link=\"external\">candy melting pot<\/a>, Ghirardelli melting wafers, and black <a href=\"https:\/\/amzn.to\/4jFtdgf\" target=\"_blank\" rel=\"noopener sponsored nofollow noreferrer\" data-wpel-link=\"external\">oil-based gel color<\/a> to dye the chocolate darker. You can buy black melting wafers, but I find that they don\u2019t taste as good. However, if you\u2019re using the tires only as a decoration, that\u2019s a more cost-effective option or simply use fondant. <\/li>\n\n\n\n<li><strong>Fill the molds. <\/strong>You\u2019ll need to pour one tire at a time, so a candy melting pot is helpful in keeping the chocolate at a consistent temperature. Otherwise, use a double boiler or a microwave, but make sure not to overheat the chocolate (see <a href=\"https:\/\/beyondfrosting.com\/how-to-melt-chocolate-chips\/\" data-wpel-link=\"internal\" rel=\"follow\">how to melt chocolate<\/a>). Once the molds were filled, I refrigerated them until they were set and repeated it for as many as I needed.<\/li>\n\n\n\n<li><strong>Add a metallic shimmer. <\/strong>Afterward, I painted the center hub caps using edible silver shimmer. I think it gives them a nice touch! To make homemade edible shimmer, combine edible glitter with a couple of drops of vodka (don\u2019t worry, it evaporates), clear vanilla, or lemon extract. Then, use a <a href=\"https:\/\/amzn.to\/4k7XO6a\" target=\"_blank\" rel=\"noopener sponsored nofollow noreferrer\" data-wpel-link=\"external\">paint brush<\/a> to brush the shimmer over the center of the tires.\u00a0<\/li>\n<\/ol>\n<\/div>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake - Hot Wheels Birthday Cake Tutorial!\" alt=\"A Hot Wheels cake in the center of a table decorated with racing themed decorations with a Hot Wheels banner, happy birthday banner, and colorful balloons in the background.\" class=\"wp-image-64782\" title=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" srcset=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450.jpg 1200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-200x300.jpg 200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-427x640.jpg 427w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-768x1152.jpg 768w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-1024x1536.jpg 1024w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-250x375.jpg 250w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-350x525.jpg 350w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-500x750.jpg 500w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-800x1200.jpg 800w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-900x1350.jpg 900w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-150x225.jpg 150w\" data-lazy-sizes=\"(max-width: 1200px) 100vw, 1200px\" data-pin-media=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450.jpg\" src=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450.jpg\"\/><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"1800\" data-pin-description=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" data-pin-title=\"Hot Wheels Cake - Hot Wheels Birthday Cake Tutorial!\" src=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450.jpg\" alt=\"A Hot Wheels cake in the center of a table decorated with racing themed decorations with a Hot Wheels banner, happy birthday banner, and colorful balloons in the background.\" class=\"wp-image-64782\" title=\"Follow this tutorial to make a Hot Wheels birthday cake decorated with buttercream and fondant, with a tunnel design running through the cake!\" srcset=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450.jpg 1200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-200x300.jpg 200w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-427x640.jpg 427w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-768x1152.jpg 768w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-1024x1536.jpg 1024w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-250x375.jpg 250w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-350x525.jpg 350w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-500x750.jpg 500w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-800x1200.jpg 800w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-900x1350.jpg 900w, https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450-150x225.jpg 150w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" data-pin-media=\"https:\/\/beyondfrosting.com\/wp-content\/uploads\/2025\/05\/Hot-Wheels-Tunnel-Cake-8450.jpg\"\/><\/figure>\n\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\">Make Ahead and Storage<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Make the cake layers in advance.<\/strong> Get a head start and bake the chocolate cake layers up to 2 days in advance.

Prepare three 6-inch round baking pans, line the bottom with parchment paper, and grease the sides.<\/li>\n<li id=\"instruction-step-2\">In a large mixing bowl, combine the sugar, vegetable oil, eggs, and vanilla extract. Beat on medium speed until well incorporated. Next, mix in the sour cream and beat until well combined.<\/li>\n<li id=\"instruction-step-3\">In a separate bowl, sift together the dry ingredients. To the batter, alternate adding half the dry ingredients followed by half of the coffee, and mix just until the flour starts to incorporate. Repeat with remaining ingredients. Use a spatula to scrape down the sides of the bowl and stir the batter from the bottom to the top to ensure it\u2019s well mixed.<\/li>\n<li id=\"instruction-step-4\">Divide the batter evenly between the three pans, it\u2019s around 2 cups per layer. Bake at 350\u00b0F for 28-35 minutes. Test the cake for doneness by inserting a toothpick into the center of the cake. If the toothpick comes out clean, the cake is done. Remove from the oven and allow to cool completely.<\/li>\n<\/ol>\n<p><strong>For the Buttercream<\/strong><\/p>\n<ol>\n<li id=\"instruction-step-5\">Cut butter into pieces. Using the paddle attachment, whip the butter for 5-7 minutes, scraping down the bowl occasionally. Beat until the butter looks light in color.<\/li>\n<li id=\"instruction-step-6\">Alternate adding 2 cups of powdered sugar at a time with the liquid ingredients: vanilla extract &amp; heavy cream. Add the salt. Ensure the powdered sugar is well combined, then whip for 1-2 minutes before adding the next cups of powdered sugar.<\/li>\n<li id=\"instruction-step-7\">Once all the powdered sugar has been added, increase speed to medium-high and beat for another 3 minutes or so until it\u2019s light and fluffy. Then turn down the mixing speed. Add a few large drops of electric blue along with one drop of royal blue and mix at a low speed, scraping down the bowl as needed. Add additional color until you reach the desired effect.<\/li>\n<li id=\"instruction-step-8\"><strong>Fondant:<\/strong> Prepare the black and white fondant squares by rolling out each color to a thin but even thickness, but not less than 1\/8\u201d thick. Use a square cookie cutter (mine was 5\/8\u201d wide) and cut the squares out (estimate about 30 squares of each color). Set aside, or place in a single layer in a flat, airtight container to be used later. These are best placed on the cake while the buttercream is fresh (and best if you\u2019re not refrigerating the cake), otherwise you can attach them but taking a toothpick to gently scratch the buttercream before applying.<\/li>\n<\/ol>\n<p><strong>To Assemble<\/strong><\/p>\n<ol>\n<li id=\"instruction-step-9\">Use a cake leveler to cut the domes off the top of the cake so all 3 layers are even and flat.<br\/>If you want to dowel the cake, stack them on top of one another and cut the dowel about 1\/8 of an inch above the top layer of cake. Also, place 2 dowel holes in a 6-inch cake board, one on each side. Set the dowel side.<\/li>\n<li id=\"instruction-step-10\">Assemble the top 2 layers first. Using 1 cup of frosting between the layers, spread it evenly with an offset spatula, and then add a light crumb coat around the outside. Fill a large piping bag, cut off about 1 inch up from the bottom. Pipe a thin layer of frosting along the outside edge of the cake, filling in any additional gaps between the layers, and a thin layer of buttercream on top of the cake. Then, use an offset spatula or icing scraper to wipe away the excess frosting, leaving just enough to coat the outside of the cake. Do not mix the crumb-coating frosting back into the bowl if it has cake debris in it. Refrigerate the cake for 15-30 minutes until the outside layer is chilled.<\/li>\n<li id=\"instruction-step-11\">For the bottom layer, lay a piece of track between the two, cutting out the middle of the cake. Leave yourself a little extra space on each side. Crumb coat each half, all the way around the cake, including the inside edge. Place a thin strip of parchment paper along the inside edge of the cake. Then, using about \u00bd- \u00be cup of buttercream, frost the top of each layer, place a cake board on top, and place the dowels through the cake board and bottom layer of the cake.<\/li>\n<li id=\"instruction-step-12\">Next, place the top 2 layers (assembled and chilled) over the dowels. Once the cake is stacked, apply another liberal crumb coat to the entire cake, making the sides as even and flat as possible. Chill for 20-30 minutes until the buttercream is set.<\/li>\n<li id=\"instruction-step-13\">Using the remaining buttercream, fill a couple of large piping bags, cut off about 1 inch up from the bottom. Pipe a layer of frosting along the outside edge of the cake, working your way from top to bottom. Add a thin layer of buttercream on top of the cake.<\/li>\n<li id=\"instruction-step-14\">Next, use an icing scraper to smooth out the frosting. First, run it under very hot water and dry thoroughly. Lightly press the scraper up against the side of the cake at a 90-degree angle, rotate the cake in a circle, applying even pressure on the scraper. Stop halfway through and clean off the scraper, run under hot water, and dry before starting again. Repeat these steps until the buttercream is smooth. Any gaps can be filled in with the additional frosting and rescraping. It may take several rounds of scraping. Finally, add a thin layer of buttercream on top of the cake and spread evenly. If possible, I recommend placing the middle piece of track through the cake and just leaving it there until you\u2019re ready to serve.<\/li>\n<\/ol>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\n\t\n\t\t\t<hr data-tasty-recipes-customization=\"secondary-color.border-color secondary-color.background-color\"\/>\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n<\/div>\n\n\n<\/div>\n\t\t\n\t\t\n\t\t\t<\/div>\r\n<br>\r\n","protected":false},"excerpt":{"rendered":"<p>I went all out with this Hot Wheels cake for my son\u2019s 5th birthday!
