Kitchen Tools You’ll Need

To bake the perfect Coffee Walnut Cake, make sure you have the following tools on hand:

• Two 8-inch round cake tins

Step-by-Step Instructions for Coffee Walnut Cake

Follow these instructions carefully to bake a moist, fluffy, and flavorful cake:

1: Prepare Your Tins and Oven

• Preheat your oven to 180°C (350°F) or 160°C fan (325°F fan).

• Grease two 8-inch cake tins with butter and line them with parchment paper.

2: Cream Butter and Sugar

• In a large bowl, beat the softened butter and caster sugar together until pale and fluffy. This process incorporates air, helping your sponge rise beautifully.

3: Add the Eggs

• Add the eggs one at a time, mixing well after each addition. If the mixture looks like it’s curdling, add a spoonful of flour to stabilize it.

4: Incorporate Coffee and Walnuts

• Stir in the dissolved coffee mixture and blend until fully combined.

• Gently fold in the flour, baking powder, and chopped walnuts. Use a spatula and avoid over-mixing to maintain a light texture.

5: Bake the Cakes

• Divide the batter evenly between the two prepared cake tins.

• Smooth the tops with a spatula and bake in the preheated oven for 20–25 minutes, or until a toothpick inserted in the center comes out clean.

6: Cool the Sponges

• Allow the cakes to cool in the tins for 5 minutes before transferring them onto a wire rack to cool completely.

7: Prepare the Coffee Buttercream

• In a mixing bowl, beat the butter until smooth and creamy.

• Gradually add sifted icing sugar, one-third at a time, mixing well after each addition.

• Stir in the dissolved coffee and vanilla extract until the frosting is light and fluffy.

8: Assemble the Cake

• Place one sponge on a serving plate and spread half of the buttercream evenly across the top.

• Sandwich with the second sponge and spread the remaining buttercream over the top.

• Decorate with walnut halves or a dusting of icing sugar, if desired.

Helpful Tips for the Perfect Coffee Walnut Cake

• Use fresh coffee: Dissolve your coffee granules in hot water for the best flavor infusion. Avoid using stale instant coffee.

• Toast your walnuts: Lightly toasting the walnuts before chopping enhances their nutty aroma and flavor.

• Room temperature ingredients: Ensure butter and eggs are at room temperature for a smooth batter and consistent rise.

• Don’t over-bake: Keep an eye on your cakes in the oven. Over-baking can dry out the sponge. Test for doneness with a toothpick.

• Custom presentation: For a fancier look, frost the entire cake, sides included, and pipe decorative swirls with extra buttercream.

Variations of Coffee Walnut Cake

The beauty of this cake lies in its adaptability. Here are some creative variations:

• Coffee Walnut Loaf Cake: Bake the batter in a loaf tin and drizzle with coffee glaze instead of buttercream.

• Coffee Cupcakes: Divide the mixture into cupcake liners and top with buttercream swirls and a walnut half.

• Gluten-Free Version: Substitute self-raising flour with a gluten-free blend and add ½ tsp of xanthan gum for structure.

• Mocha Walnut Cake: Add 2 tbsp cocoa powder to the batter for a chocolate-coffee fusion.
