Pretty much everyone that knows me is aware of my love for Reese’s Peanut Butter Cups. I’m surprised, and I’m sure they would be too, that it’s taken me this long to make a Reese’s Peanut Butter Cake. It’s probably because I eat all the PB Cups before I get round to it! Well I finally managed it, and if you love PB Cups as much as me, you’re going to love this cake! It’s a peanut butter sponge, a chocolate and peanut butter buttercream, drizzled with Reese’s Spread (which is a peanut butter version of Nutella that you NEED to try!) and of course topped with Reese’s Peanut Butter Cups!
Step by step…
I made the sponge by mixing the butter, peanut butter and caster sugar together. Then I whisked in eggs, followed by self raising flour.
I baked the cake, then let them cool. For the buttercream, I mixed together butter, peanut butter, icing sugar, cocoa powder and a little milk until smooth.
To decorate, I piped the buttercream between each layer and drizzled over some Reese’s Spread.
To finish the Reese’s Peanut Butter Cake, I decorated it with Reese’s Peanut Butter Cups and Mini Peanut Butter Cups. I also added some sprinkles!
Tips for making the Reese’s Peanut Butter Cake:
- I used Reese’s Spread to drizzle between the layers and on top. If you can’t find any, you can omit this step entirely, or drizzle peanut butter instead, or mix 1 tbsp cocoa powder into the peanut butter to make it chocolatey!
- You could also decorate the cake with chopped peanuts if you prefer!
- I used a Wilton 8B tip to decorate the cake, but use your favourite piping nozzle, or spread the buttercream on with a palette knife or spoon.
- You can freeze the sponges undecorated, wrap them well in cling film before freezing. You can make the buttercream in advance, store it in an airtight container. It will last as long as the expiry date on the butter you use.

Instructions
-
Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and grease and line three 8" cake tins

Make the sponge by mixing the butter, peanut butter and caster sugar in a large bowl with a spoon until fluffy, or mix using an electric mixer
-
Add the eggs and whisk until fully incorporated
-
Add the self raising flour and whisk in until you can't see any flour anymore
-
Divide the mixture between the tins, use scales for accuracy
-
Bake them for 30-35 minutes or until a skewer inserted in the middle comes out clean. Leave them to fully cool either in the tins or on cooling racks
-
If the cakes have domed on top, level them off with a cake leveller or a serrated knife

When it starts to come together add the milk, and whisk until smooth

Stack the sponges up on your plate or cake stand, piping or spreading buttercream between each layer. If you're using it, drizzle the Reese's Spread over each layer of buttercream, letting it drizzle over the sides
-
When you get to the last layer, pipe larger rosettes all around the edge and smaller ones in the centre
-
Decorate with the Reese's Peanut Butter Cups and Mini Cups, and sprinkles if using
-
Serve immediately, store leftovers in an airtight container in a cool place and eat within 3 days
Recipe Notes
I got the Reese's Spread from Sainsburys. If you can't find any, you could drizzle peanut butter between the layers. Or if you want it chocolatey, mix 1 tbsp cocoa powder into the peanut butter!
