Cake Ingredients

  • 175g unsalted butter, softened, plus extra for greasing the tin
  • 175g golden caster sugar 
  • 3 large eggs
  • 50g cocoa powder
  • 100g self-raising flour
  • 1-2 tsp milk

Buttercream ingredients


  • Heat oven to 190C/170C fan/gas 5. Grease with butter and line two 18cm sandwich tins with baking parchment.
  • Using an electric mixer, beat the unsalted butter and golden caster sugar together in a bowl until creamy and light in colour. Then add 1 egg while still mixing.
  • Sieve the cocoa powder, self-raising flour and a pinch of salt into another bowl, stir to combine and add a third of this to your wet mixture.
  • Once combined, add 1 more egg and another third of the flour mixture, then add the last egg and the remaining flour and beat until you have a smooth, thick batter.
  • Divide the mixture evenly between the tins and smooth out to the edges with the back of a spoon.
  • Bake for 20-25 mins until springy to the touch. Take out of the oven and leave to cool a little in the tins for 10 mins before turning out onto a wire rack to cool completely.
  • Meanwhile, make the buttercream by melting the chocolate in the microwave, using 20 second bursts, leave to cool.
  • Beat the softened unsalted butter and half of the icing sugar together until light and fluffy. Add the remaining icing sugar and melted chocolate and mix everything together.
  • To assemble the cake, place your first cake on the plate or cake stand you would like to use, then spread the top with half the icing, leaving a 1cm border around the edge.
  • Place your second cake on top in line with your first and push down gently, then spread the remaining icing over the top.
