Ingredients

Scale

For the cake:

  • 225g self-raising flour

  • 225g unsalted butter (softened)

  • 225g caster sugar

  • 4 large eggs

  • 1 tsp baking powder

  • 2 tbsp instant coffee (dissolved in 1 tbsp boiling water)

  • 75g chopped walnuts

  • A pinch of salt

For the coffee buttercream:

  • 150g unsalted butter (softened)

  • 300g icing sugar

  • 2 tsp instant coffee (dissolved in 1 tbsp hot water)

  • 1 tbsp milk (if needed for consistency)

For decoration:

  • Walnut halves

  • A dusting of icing sugar (optional)

Instructions

Step 1: Prepare the Cake Tins

Grease and line the bases of your cake tins with parchment paper. Preheat your oven to 180°C (160°C fan) / 350°F.

Step 2: Mix the Batter

In a large bowl, beat together butter and caster sugar until light and creamy. Add the eggs one at a time, beating well after each addition.

Step 3: Add Dry Ingredients

Sift in the self-raising flour, baking powder, and a pinch of salt. Fold gently using a spatula until the mixture is smooth.

Step 4: Add Coffee and Walnuts

Stir the dissolved coffee into the batter, making sure it blends evenly. Fold in the chopped walnuts for added texture.

Step 5: Bake the Cakes

Divide the batter evenly between both tins. Smooth the tops and bake for 25–30 minutes or until the cakes spring back when touched. Allow them to cool in the tins for 10 minutes before transferring to a wire rack.

Step 6: Make the Coffee Buttercream

Beat the softened butter until smooth. Gradually add icing sugar and beat until fluffy. Pour in the dissolved coffee and mix until creamy. Add a splash of milk if needed to loosen the mixture.

Step 7: Assemble the Cake

Place one sponge layer on a plate and spread half the buttercream over it. Add the second layer and spread the remaining buttercream neatly on top. Decorate with walnut halves.

Step 8: Serve and Enjoy

Slice and serve with tea, coffee, or as a dessert after dinner. The cake stays moist for days when stored properly.
