Ingredients You Need for Hairy Bikers Coffee and Walnut Cake Recipe
For the Sponge:
- 225g Softened unsalted butter
- 225g Golden caster sugar
- 225g Self-raising flour
- 1 tsp Baking powder
- 4 Large eggs
- 50g Chopped walnuts
- 2 tbsp Instant coffee granules
- 1 tbsp Boiling water
For the Buttercream:
- 150g Softened butter
- 300g Icing sugar
- 1.5 tbsp Instant coffee granules
- 1 tbsp Boiling water
- Extra walnut halves for decoration
Step-by-Step Guide
1. Preheat and Prep
Heat your oven to 180°C. Grease your two cake tins with a little bit of butter. Line the bottoms with circles of baking parchment paper. This stops the cake from sticking to the pan.
2. Dissolve the Coffee
Put your coffee granules into a small bowl. Add the boiling water and stir until it is smooth. Set this aside to cool down for a few minutes. This provides the deep flavor.
3. Cream Butter and Sugar
In a large bowl, beat the butter and sugar together. Use an electric whisk for the best results. Keep going until the mixture looks pale and very fluffy. This adds air to the cake.
4. Add the Eggs
Whisk in your eggs one at a time. Add a spoonful of flour with each egg to stop curdling. Mix well after each addition until the batter is smooth and combined.
5. Fold in Dry Ingredients
Sift the remaining flour and baking powder into the bowl. Add the chopped walnuts and the cooled coffee liquid. Use a large metal spoon to gently fold everything together. Do not overmix.
6. Bake the Cakes
Divide the batter equally between the two tins. Smooth the tops with a spatula. Bake for about 25 minutes. They should be golden brown and spring back when touched.
7. Cool the Sponge
Leave the cakes in the tins for five minutes. Then, turn them out onto a wire rack. Peel off the parchment paper. Let them cool completely before you start the icing.
8. Make the Buttercream
Beat the butter and icing sugar until smooth. Dissolve more coffee in water and add it to the mix. Whisk until it is light and airy. This is the best part of the cake.
9. Assemble and Decorate
Spread half the buttercream on one cake layer. Top with the second cake. Spread the rest of the icing on top. Finish by placing walnut halves around the edge for a professional look.
Expert Tips & Variations
- Toast the Walnuts: Lightly roast your walnuts in a pan before adding them. This makes the flavor much deeper and crunchier.
- Stronger Coffee: If you love a punchy flavor, use espresso powder instead of instant coffee.
- Gluten-Free: You can use a gluten-free flour blend. Just add an extra splash of milk to keep it moist.
- Storage Tip: Keep the cake in an airtight container. It will stay delicious for up to three days.
- Add Chocolate: Fold in some dark chocolate chips for an extra indulgent twist.
Interesting Facts About Coffee and Walnut Cake
Did you know this cake became popular in Britain during the 1930s? It has been a staple of village fetes for nearly a century.
The Hairy Bikers popularized this version by emphasizing the “all-in-one” method for busy home cooks.
Walnuts are actually the only nuts that contain significant amounts of Omega-3 fatty acids. This makes the cake feel slightly more “virtuous” while you enjoy a slice.
Perfect Dishes to Serve With
This cake is the star of the show on its own. However, a dollop of clotted cream on the side is heavenly. If you want a full tea party, serve it with finger sandwiches.
A hot pot of Earl Grey tea cuts through the sweetness beautifully. For a cold option, try a glass of iced latte to double down on the coffee theme.
Storage and Reheating Tips
- Room Temperature: Store in a cool, dry place in a sealed tin for 3 days.
- Freezing: You can freeze the sponge layers without icing for up to one month. Wrap them tightly in plastic wrap.
- Reheating: If the cake gets a bit dry, microwave a slice for 10 seconds. It softens the buttercream and makes it taste fresh.
- Avoid the Fridge: Don’t put the cake in the fridge. Cold air can make the sponge go hard and dry.

FAQs about Hairy Bikers Coffee and Walnut Cake Recipe
Can I make this cake without eggs?
Yes, you can use a commercial egg replacer or applesauce. However, the texture will be denser than the original recipe. The eggs provide the lift and structure needed for a fluffy sponge.
How do I prevent the walnuts from sinking to the bottom?
Make sure your cake batter is thick enough. You can also toss the chopped walnuts in a little bit of flour before folding them in. This helps them grip the batter during the baking process.
Why did my buttercream turn out runny?
This usually happens if the butter was too melted or you added too much liquid. Make sure the coffee water is cooled down completely. If it is still runny, add more icing sugar to thicken it.
