Fudgy Chocolate Cake with Creamy Peanut Butter Frosting

By Stuart Vettese (aka Cakeyboi) (

Yield: 8 servingsPrep time: Cook time:

  • 260 grams self-raising flour
  • 3 tablespoons unsweetened cocoa powder
  • 1 ½ teaspoons bicarbonate of soda
  • ½ teaspoon salt
  • 225 grams granulated sugar
  • 3 large eggs
  • 225 ml vegetable oil
  • 285 ml semi-skimmed milk (or milk of your choice)
  • 3 tablespoons golden syrup
  • 225 grams unsalted butter softened
  • 250 grams smooth peanut butter
  • 450 grams icing sugar
  • ½ teaspoon vanilla extract
  • 100 grams dark chocolate chips
  • 2 tablespoons coconut oil
  1. Preheat the oven to 180C (160C) and line and grease three 8” cake tins.In a bowl sift together the flour, bicarb, salt and cocoa powder.
  2. Stir in the granulated sugar and make a well in the centre.
  3. In a jug, beat together the eggs, veg oil, 225 ml of the milk and golden syrup. Pour this into the dry ingredients and mix well with a spoon or spatula until smooth and all the ingredients have combined.
  4. Divide the cake batter equally between the three cake tins and place into the oven for 20 to 25 minutes. The cakes will be baked when a toothpick comes out clean from the centre. Allow to cool for 10 minutes in the tins, before turning out on to cooling racks and letting them cool completely. 
  5. To make the frosting, beat the peanut butter and softened butter together until smooth in a food mixer or with a hand held mixer.
  6. Add 50 grams of the icing sugar, the remaining milk and vanilla and beat to combine.
  7. Add the rest of the icing sugar gradually until the frosting is smooth and slightly thicker.
  8. Spread the frosting on each layer of the cake and place on top of one another. Coat the top and sides with a thin layer of the frosting and refrigerate for at least half an hour, to let the frosting firm up.
  9. Remove from the fridge and coat the top and side of the cake more liberally. To achieve a clean finish, heat your palette knife up (either over a gas burner or with some hot water) before smoothing over the frosting. Place into the fridge for at least an hour to cool completely.
  10. To make the chocolate topping, melt the chocolate chips and coconut oil together in a bowl over a simmering pan of water. Let it cool slightly before spooning over the cake or placing it in a piping bag and piping it over the top of the cake. Go close to the edges so the chocolate drips. It should chill and go solid before getting to the bottom of the cake.
  11. Chill until ready to serve. Enjoy!
