How to Make Mary Berry Coffee and Walnut Cake

Step 1: Preheat the Oven
Preheat your oven to 180°C (160°C fan) or 350°F. Grease and line two 20cm round cake tins.
Step 2: Cream Butter and Sugar
In a large bowl, beat the butter and sugar together until light and fluffy.
Step 3: Add Eggs and Coffee
Beat in the eggs one at a time, adding a spoonful of flour with each to prevent curdling. Stir in the dissolved coffee.
Step 4: Fold in the Dry Ingredients
Gently fold in the remaining flour and chopped walnuts until well combined.
Step 5: Bake
Divide the mixture between the two tins and smooth the tops. Bake for 25–30 minutes until golden and a skewer comes out clean. Cool in tins for 5 minutes before transferring to a wire rack.
Step 6: Prepare the Buttercream
Beat the butter until soft, then gradually add the icing sugar and coffee. Beat until smooth and fluffy.
Step 7: Assemble the Cake
Spread half the buttercream on one sponge, sandwich the second sponge on top, and cover the top with the remaining buttercream. Decorate with walnut halves.
Tips for Success
Use Room Temperature Ingredients
This helps everything blend smoothly and creates a light sponge.
Strong Coffee is Key
Use espresso or instant coffee for a bold flavor that shines through.
Don’t Overmix
Mix just until combined to keep the cake light and airy.
