Peanut-butter fudge cake

This is my go-to cake recipe and it is alway a crowd pleaser (unless the crowd has a peanut allergy, in which case it willstill knock ’em dead).

I almost feel like I am giving away my greatest cullinary secret by posting this. I hope you all enjoy it.


Makes 2 x 22cm cakes



2 cups sugar

1 3/4 cups flour

3/4 cup cocoa

1 1/2 tsp baking powder

1 1/2 tsp baking soda

1 teaspoon salt

2 eggs

1 cup buttermilk

1/2 cup unsalted butter, melted

1 tbsp vanilla extract

1 cup hot coffee

4 heaped tbsn peanut-butter


Peanut-butter Chocolate Fudge Frosting

1/2 cup smooth peanutbutter

1/2 cup unsalted butter, room temperature

2.5 cups icing sugar, sifted

3/4 cup cocoa powder, sifted

1/2 tsp vanilla extract

3 tbsn milk/cream (I use a lot more)

Salted peanuts, for topping


  1. Pre-heat the oven to 180°c. Grease 2x22cm cake tins.
  2. Combine all the dry ingredients.
  3. Mix together the eggs, buttermilk, melted butter and vanilla and combine with the dry ingredients.
  4. Place the hot coffee and peanut-butter in a bowl and allow the peanut-butter to soften/melt slightly and incorporate into the batter. Mix thoroughly.
  5. Pour the batter into the prepared cake tins and place in the oven.
  6. Bake for 35-40 minutes until a skewer inserted comes out clean. (If you feel that the cake is browning too quickly, turn the heat down half way)
  7. Remove the cakes from the oven and allow to cool on a wire rack.
  8. To make the frosting, beat the peanut-butter and the butter until well combined and fluffy.
  9. Slowly beat in the icing sugar and cocoa powder until the mixture is quite stiff (it ends up looking like breadcrumbs when i make it). Add the vanilla and the milk/cream and beat until glossy and creamy.
  10. When the cakes are completely cooled, frost them using the peanut-butter frosting. Sprinkle over the salted peanuts and serve.

 I usually decorate it with chopped peanut brittle and crushed Flake chocolate.

  1. I love you, my hips and my tummy loves you. My personal trainer probably loves you most as this will earn him more money in his pocket in order to work this off 🙂

    • A quick and easy cheat for this cake is to use a box cake and add 1/3 cup peanut butter, and then icing as per recipe. The secret to the recipe is 100% in the icing. Now you have no excuse. Serve it with coffee after Christmas lunch or dinner instead of a heavy dessert. 🙂
