Who wants a big slice of my vegan chocolate peanut butter cake?!
I will never claim to be peanut butter's biggest fan but when it's combined with the sweetness of powdered sugar, it really does neutralise the taste.
If you love peanut butter in all of its forms then don't worry. You clearly love peanut butter desserts no matter what.
However, if you would prefer that nuttiness to be a little bit less nutty, check out this chocolate peanut butter cake.
If you just can't stop baking at the moment, I recommend that you also try my vegan banana chocolate chip muffins! They're so fluffy!

HOW TO MAKE PEANUT BUTTER CAKE
Below you can take a look at a quick overview of how to make my peanut butter cake. The full method is down on the recipe card. If you’re looking for detailed steps, be sure to see it!
In a large bowl, mix your dry ingredients. Then add in your wet but don't over-mix.
Pour your cake batter into the two prepared cake pans and bake for 25 minutes or until a skewer comes out clean.
While the cake halves are cooling, make the peanut butter frosting. In a large bowl, beat all the ingredients other than the powdered sugar and the plant milk. Mix until creamy then gradually add the powdered sugar. When the consistency is like breadcrumbs add the plant milk. Mix again until creamy.
If your cake is now cool, spread a thick layer of the peanut buttercream onto the flat side of one of the cakes. Spread some extra buttercream on top, then place the cake into the fridge for 30 minutes so that the filling can thicken a little.
- Grease your cake tin before you pour the batter in as this will make life so much easier for yourself when it's time to take the cake out. After a few taps the cake should come out nicely when the tin is greased.
- Don't over-mix your cake batter as this can affect the texture of your cake. Mixing wet ingredients with flour activates the gluten but when you over-mix, this can be detrimental to your cake.
PEANUT BUTTER FROSTING
For the peanut butter frosting I used:
- Peanut butter - I love using smooth peanut butter but crunchy always works fine.
- Vegan Butter - I usually choose vegan butter blocks but for this peanut butter cake, I used Vitalite margarine which also works exceptionally well in baking.
- Vanilla extract - Just a teaspoon.
- Salt - Half a teaspoon this time.
- Powdered Sugar - I know that 400g sounds like a lot. It honestly creates such a nice consistency after the plant milk has been added in. Neither too thick or too thin.
- Plant Milk - This makes the buttercream super creamy.
HOW DO I ASSEMBLE THE CAKE?
After you have removed ones of the cakes from the tins, place it onto a flat surface. Next, you can spread the peanut buttercream onto the flat side of the cake.
Firstly, make sure that the cake has fully cooled down. Otherwise, the filling will begin to melt.
Secondly, don't spread too much of the buttercream onto the cake. This will cause most of it to ooze out when the second cake half is placed on top.
When you have placed the second cake over the buttercream, spread more of the filling on top of the cake. I say the more the merrier! You can also add your topping of choice.
VARIATIONS AND SUBSTITUTIONS
- I used vegetable oil for my own peanut butter cake but I have found canola oil to work equally as well. Use it as a 1:1 substitute for vegetable oil if you prefer.
- I used soy milk as it never lets me down but many plant milks will work in this recipe. You may prefer almond milk or oat milk. You will still get excellent results.
- I haven't tried to make this recipe gluten-free yet but if you have gluten-related dietary restrictions, try substituting the all-purpose flour for gluten free flour 1:1. The texture will be more dense but I know that some people prefer that way.
- Try using crunchy peanut butter instead for a crunchier experience.
HOW TO STORE PEANUT BUTTER CAKE?
You can store this peanut butter cake in the refrigerator. Simply place a slice inside an airtight container and consume within 10 days. Let the cake sit at room temperature for 20-25 minutes before serving.
Alternatively, you can freeze your cake for up to 4 months. Again make sure each slice is inside an airtight container.
