How to Make Classic Coffee & Walnut Cake

PIN IT

Step 1 – Prepare the Oven and Tins

Preheat your oven to 180°C (350°F). Grease and line two cake tins. This step always reminds me of baking with my grandmother—she never skipped lining the tins!

Step 2 – Cream Butter and Sugar

Beat the butter and sugar together until pale and fluffy. This should take about 3–4 minutes. The mixture should look light and creamy.

Step 3 – Add Eggs

Add the eggs one at a time, mixing well after each addition. If the mixture starts to curdle, add a spoonful of flour.

Step 4 – Add Coffee and Flour

Stir in the dissolved coffee. Then fold in the flour, baking powder, and chopped walnuts gently.

Step 5 – Bake the Cakes

Divide the mixture between the tins and bake for about 20–25 minutes until golden and springy to the touch. Let them cool completely.

Step 6 – Make the Buttercream

Beat butter until creamy, then add icing sugar, coffee mixture, and milk. Beat until smooth and fluffy.

Step 7 – Assemble the Cake

Spread buttercream on one cake layer, place the second layer on top, then frost the top and decorate with walnuts.

What to Serve with Classic Coffee & Walnut Cake

This cake is perfect with:

• Hot coffee
• Cappuccino
• Earl Grey tea
• Vanilla ice cream
• Fresh whipped cream

Serve it slightly chilled or at room temperature for the best flavor.

Tips for Making It Perfect

Always use room temperature butter and eggs. This helps create a smooth batter and fluffy cake.

Do not overmix once you add the flour, or the cake will become dense.

If you want perfectly flat cake layers, use cake strips around your tins.

You can make the sponge a day ahead and frost the next day—it actually tastes even better!

Storage Instructions

Store the cake in an airtight container at room temperature for up to 2 days.

You can refrigerate it for up to 5 days. Let it come to room temperature before serving.

To freeze, wrap the sponge layers in plastic wrap and freeze for up to 2 months.

Frequently Asked Questions

Yes, but make sure it is very strong and cooled before adding to the batter.
