Instructions
 

Start by making the coffee and walnut cakes

  • First dissolve the coffee in 3 tablespoons boiling water. Stir to combine and then place in the fridge to cool.
  • Preheat oven to 180°C fan / 200°C conventional. Lightly grease two 20cm round cake tins with butter and line the base with greaseproof paper.
  • In a large mixing bowl, beat the margarine and golden caster sugar until light and fluffy.
    300 g Margarine or unsalted butter, 300 g Golden caster sugar
  • Beat in the eggs one at a time until fully incorporated.
    3 large Eggs
  • Gently fold in the flour until the cake mixture is smooth.
    300 g Self-raising flour
  • Add the cooled coffee and chopped walnuts. Fold until mixed through.
    2 tbsp Instant espresso powder or instant coffee granules, 100 g Walnuts
  • Divide the mixture evenly between the cake tins. Bake for 30-35 minutes until risen, golden on top and a toothpick inserted in the middle of the cake comes out clean.
  • Leave to cool for 15 minutes in the baking tin, before turning out onto a wire rack and cooling completely.

Make the coffee buttercream

  • First dissolve the coffee in 2 tablespoons boiling water. Stir to combine and then place in the fridge to cool.
    2 tbsp Instant espresso powder or instant coffee granules
  • Beat the butter until really soft, smooth and fluffy.
    250 g Salted butter
  • Sift in the icing sugar and beat until smooth and combined.
    500 g Icing sugar
  • Add the cooled coffee and use a spatula to fold the coffee buttercream together until combined.

Assemble the cake

  • Place one of the cake layers on a cake stand or plate. If the cake is domed on top, use a sharp knife to level it off so it's flat.
  • Spread half of the coffee buttercream on top into an even layer.
  • Place the second coffee cake on top and lightly press down to sandwich the sponge layers together.
  • Spread the remaining buttercream on top. Finish by placing the walnut halves around the outside edge. Slice and enjoy!
