This Gluten-Free Vegan Lemon Poppy Seed Layer Cake is soft and fluffy, sweet and tangy and a little nutty! It’s covered in a rich, lemony frosting that tastes like cream cheese. It’s easy to make as it comes together in one bowl, and is easily customisable too. It’s also refined sugar free. My Lemon Poppy Seed Cake recipe has been really popular, so I decided to make this layer-cake version, which is perfect for birthdays, Easter, Mother’s Day, baby showers and everything in between!
How to make the cake
Scroll down to the bottom of the post for the full recipe.
- Mix together the ingredients for the cake in a mixing bowl.
Tip: Use a measuring jug to measure out the plant-based milk.
Tip: Line the tins with greased baking paper to make the sponges easier to remove afterwards.
- Bake in the oven for 15 minutes.
- Transfer onto a wire rack and leave to cool completely before applying the frosting.
How to make the frosting
- Place the coconut milk, lemon juice and maple syrup in a bowl.
- Use an electric whisk to whip until thick and fluffy.
Tips for making the frosting
- You’ll need to keep your tin of coconut milk in the fridge overnight for the rich, creamy bit to separate from the watery bit at the bottom. Make sure it is full-fat coconut milk, otherwise this separation won’t happen and you won’t be able to make this frosting!
- Open the tin upside down – the coconut cream will be at the bottom and you can just pour off the watery liquid (save this for adding to soups, curries or smoothies).
- Place the thick, creamy part into a bowl.
- Use an electric whisk (or a manual one and a lot of elbow grease) to whip up the coconut cream until light and fluffy.
How to frost the cake
- Once the sponges have cooled completely, place one sponge on a large plate or cake stand.
- Cover with half of the frosting.
Tip: Apply the frosting to the cake using a palette knife for frosting.
- Place the other sponge on top and use the remaining frosting to cover the top and sides of the cake.
How to decorate
I decided to decorate this cake with lemon peel and poppy seeds, but you can use whatever you like!
How long does this Lemon Poppy Seed Cake keep for?
This Lemon Poppy Seed Cake tastes best eaten on the day it’s made, but keeps covered in the fridge for up to a few days.
Substitutions you can make
- You can use any type of oil: coconut oil, vegetable oil, olive oil etc.
- You can use any type of liquid sweetener: maple syrup, agave syrup, brown rice syrup etc.
- You can use any type of plant-based milk: almond milk, oat milk, soy milk, cashew milk, rice milk etc.
- If you don’t need the cake to be gluten-free, you can replace the gluten-free flour with plain flour.
- The ground almonds can be replaced with ground walnuts.
- For a nut-free version, use ground sunflower seeds instead of ground almonds, use a nut-free plant-based milk and omit the frosting or make a different frosting.
Tips for baking with lemons
- For optimum lemon flavour, I would recommend using fresh lemons (not ones that you’ve had sitting in your fruit bowl for weeks!) and organic ones if possible.
- You have to be careful when baking with lemon juice, as the acidity and lemon flavour can really vary depending on the lemons you use.
- I would recommend tasting the lemon juice you’re using and adjusting the amount of lemon juice you use accordingly.
- For the lemon zest, make sure you use unwaxed lemons.

Instructions
For the cake:
-
Preheat oven to 180 degrees Celsius (350 degrees Fahrenheit).
-
Place the coconut oil in a large bowl and melt over a saucepan of boiling water or in the microwave (skip this step if using any other oil).
-
Once melted, add the milk to the same bowl along with the lemon juice, lemon zest, maple syrup, vanilla, salt, poppy seeds and ground almonds.
-
Sift in the flour, baking powder and bicarbonate of soda.
-
Mix well, adding a tiny splash more milk if it’s looking too dry.
-
Transfer mixture between two small greased baking tins lined with baking paper (I used two 7inch/18cm tins).
-
Bake in oven for around 15 minutes until risen and an inserted skewer comes out clean.
-
Once out the oven, immediately remove cakes from baking tins and transfer onto a wire rack to cool.
For the frosting:
-
You’ll need to keep your tin of coconut milk in the fridge overnight for the rich creamy bit to separate from the watery bit at the bottom. Make sure it is full-fat coconut milk, otherwise this separation won’t happen and you won’t be able to make this cream!
-
Open the tin upside down – the coconut cream will be at the bottom and you can just pour off the watery liquid (save this for adding to soups, curries or smoothies).
-
Place the thick, creamy part into a bowl.
-
Add the maple syrup and lemon juice.
-
Use an electric whisk (or a manual one and a lot of elbow grease) to whip up the coconut cream until light and fluffy.
To frost and decorate the cake:
-
Once the sponges have cooled completely, place one sponge on a large plate or cake stand, and cover with half of the frosting – for best results, use a palette knife to do this.
-
Place the other sponge on top and use the remaining frosting to cover the top and sides of the cake.
-
Decorate with lemon peel and poppy seeds, if desired.
-
This cake tasted best eaten on the day it was made, but keeps covered in the fridge for up to a few days.
Notes
**You can alternatively use a thick coconut yogurt.
