Vegan peanut butter cake - this delicious peanut butter sheet cake with chocolate chips and roasted peanuts is the perfect snacking cake.

This vegan peanut butter cake is a lovely, simple traybake cake that is great to snack on, but would also be indulgent enough to serve at a party or birthday.

It consists of a melt-in-the-mouth tender vegan peanut sponge cake which is generously topped with chopped chocolate and roasted peanuts. The crunch from the peanuts provides a great textural contrast to the soft cake.

It is moist, delicious, extremely satisfying and really easy to make too, and is the kind of cake that is bound to please everyone!

I veganised and adapted the recipe from One Tin Bakes Easy by the genius Edd Kimber.

What Do I Need To Make Vegan Peanut Butter Cake?:

Peanut butter: A smooth, creamy peanut butter is best, rather than the natural kind. I use Whole Earth smooth.

Oil: Use a neutral flavoured oil such as sunflower or a mild olive oil. I wouldn't use coconut oil here unless you have no other option.

Milk: You can use any kind you like but it should ideally be unsweetened and soy milk is best as it has the highest protein content.

Sugar: I use light brown soft sugar as it adds extra moisture and flavour. Caster, granulated or coconut sugar will also work.

Vinegar: This reacts with the raising agents to make the cake rise.

Vanilla: Extract is better than essence and you can also use vanilla bean paste.

Plain flour: Just regular plain (all-purpose) flour. I don't recommend swapping it for wholemeal, it will make the cake too dense.

Baking powder and soda: A mix of the two provides the best rise and light, soft texture.

Dark chocolate: You can use either chopped dark or milk chocolate or chocolate chips.

Roasted peanuts: I like to use salted roasted peanuts as the salt goes well with the dark chocolate.

Top Tips:

All of my recipes are developed using grams, and as with all of my baking recipes I really do recommend using the metric measurements with a digital scale rather than the cup coversions. Cups are a wildly inaccurate measuring system and you will get far better, more consistent results using a scale, not to mention that it is also easier and less messy than cups!

Make sure that you don't over-beat the batter as that can make the cake tough. Just mix it until no dry lumps remain. I recommend stirring it by hand with a balloon whisk.

Because it is important not to over-beat the batter, you need to make sure that your wet ingredients and your dry ingredients are extremely well mixed in their separate bowls before you combine the two together.

This cake can be baked in two 20cm (8in) round cake tins instead of the sheet pan. It would be great filled and topped with peanut butter buttercream instead of the chocolate and peanuts.

The cake will keep for up to 4 days in an airtight container at room temperature.

Can I Freeze It?:

Yes this vegan peanut butter cake freezes well, either whole or in slices.

Make sure it is completely cold before freezing, wrap it well to prevent freezer burn and freeze for up to three months. Allow to defrost at room temperature to serve.
