If you like monster cookies, you\u2019ve got to try monster bars. They\u2019re just as delicious and require less hands-on time. Best part? This recipe is loaded with chocolate chips and M&Ms.<\/p>\n Growing up, I made at least one pan of bars or batch of cookies a week. I\u2019d thumb through the same church cookbook, its pages stained with butter, dusted with flour, and softened from years of enthusiastic baking.<\/p>\n One of my favorite recipes to make was monster cookies<\/a>. I eventually expanded into monster bars.<\/p>\n If you\u2019re not familiar, monster cookies (and monster bars) are a Midwestern favorite. They\u2019re packed with oats, peanut butter, chocolate chips, and M&Ms. Pretty much all of the good stuff.<\/p>\n They\u2019re popular at picnics<\/a>, church potlucks<\/a>, and bake sales. Kids love them. Adults love them, too.<\/p>\n If you\u2019re looking to make a pan of bars for an event \u2013 or perhaps to bring to a friend or neighbor in need \u2013 consider these delicious monster bars.<\/p>\n My favorite part about growing up in small-town Minnesota is how well neighbors and friends cared for each other. This often involved making a meal or dessert and dropping it off at someone\u2019s door. If someone has been sick, if someone has lost a loved one, if someone is going through a hard time\u2026 food might just be the thing that helps them get through.<\/p>\n Consider making these peanut butter monster bars for someone who could use a pick-me up.<\/p>\n<\/div>\n<\/div>\n Peanut butter is one of the signature ingredients in Monster Bars, adding both flavor and structure to the dough. If you need a peanut-free version, you can experiment with a creamy sunflower seed butter, though the flavor and texture may be slightly different. I haven\u2019t tested this substitution, so I can\u2019t guarantee the results.<\/p>\n<\/div>\n<\/div>\n Yes, but the texture will be different. Old-fashioned oats give Monster Bars their hearty, chewy texture, while quick oats create a softer, more uniform bar. For the best results, I recommend sticking with old-fashioned oats.<\/p>\n<\/div>\n<\/div>\n Absolutely! Once the bars have cooled completely, cut them into squares and store them in an airtight container or freezer bag. They\u2019ll keep well in the freezer for up to 3 months. Thaw them at room temperature for about 30 minutes before serving.<\/p>\n<\/div>\n<\/div>\n Dry monster bars are usually the result of overbaking or measuring too much flour or oats. Bake just until the edges are set and the center no longer looks wet. The bars will continue to firm up as they cool. For the most accurate measurements, spoon the flour into your measuring cup and level it off rather than scooping directly from the bag.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n![\"Monster](\"https:\/\/www.cheaprecipeblog.com\/wp-content\/uploads\/2026\/07\/Monster-cookie-bars-640x960.jpg\")
