The Hairy Bikers’ Coffee and Walnut Cake is a luscious, layered sponge cake bursting with rich coffee flavor and generously speckled with crunchy walnuts.

Whether you’re making it for a birthday celebration, a weekend treat, or simply to impress at a coffee morning, this cake is an absolute showstopper that carries the warmth of nostalgia with every bite.
To make this showpiece, here’s what you’ll typically need:

Creating the Hairy Bikers’ coffee and walnut masterpiece doesn’t require anything too fancy. Here’s your kitchen arsenal:
Step 1: Preheat and Prep
Preheat your oven to 180°C (160°C fan) / 350°F / Gas 4. Grease and line two 20cm round cake tins with baking parchment.
Step 2: Cream the Butter and Sugar
In a large mixing bowl, cream the butter and sugar together until pale and fluffy. This step is crucial for a light, airy texture-beat it longer than you think you need to!
Step 3: Add the Eggs
Beat in the eggs one at a time, adding a spoonful of flour with each to prevent curdling. Once combined, stir in the dissolved coffee.
Step 4: Combine the Dry Ingredients
Sift the flour and baking powder into the bowl. Fold gently with a spatula until just combined-don’t overmix or the cake could turn dense.
Step 5: Fold in the Walnuts
Gently stir in the chopped walnuts. You want them evenly distributed but not broken down into crumbs.
Step 6: Bake
Divide the mixture evenly between the two tins and level the tops. Bake for 20-25 minutes or until golden and springy to the touch. A skewer inserted into the center should come out clean.
Step 7: Cool
Allow the cakes to cool in the tins for 5-10 minutes, then turn out onto a wire rack to cool completely.
Step 8: Make the Buttercream
While the cakes cool, beat the softened butter until smooth. Gradually add the icing sugar, beating until fluffy. Mix in the dissolved coffee and a splash of milk if needed to loosen the texture.
Step 9: Assemble and Decorate
Place one cake layer on your serving plate. Spread with half the buttercream.
Place the second sponge on top and cover the top with the remaining icing. Decorate with walnut halves or a sprinkle of chopped walnuts for that signature finish.
The Hairy Bikers’ Coffee and Walnut Cake is a glorious example of British baking done right. It’s cozy yet celebratory, rustic but refined.
The interplay between bitter coffee, crunchy nuts, and sweet sponge is pure comfort in every slice. Whether you’re a beginner baker or a seasoned cake enthusiast, this recipe is wonderfully forgiving and endlessly rewarding. So go ahead-brew a fresh pot of coffee, tie on your apron, and bake your way into the hearts of friends and family with this timeless treat.
The Hairy Bikers’ classic coffee and walnut cake is already a deliciously moist, nutty, and aromatic showstopper. But sometimes, a twist on the traditional can reinvigorate a favorite and give it a new life at your table. Here are some ways you can remix the recipe while preserving its nostalgic essence:
Espresso Upgrade:
Instead of using instant coffee granules dissolved in water, why not use a freshly pulled espresso shot?
This intensifies the coffee flavor, giving the sponge a richer, more robust taste. Cold brew concentrate also works if you want smooth depth without the bitterness.
Maple-Walnut Marvel:
Swap out some of the sugar in the batter for pure maple syrup. The maple’s warm, caramel tones blend beautifully with the walnuts, bringing a natural sweetness that’s complex and comforting.
Buttercream Remix:
Traditional coffee buttercream is lovely, but adding mascarpone or cream cheese gives it a tangy, luscious twist. For even more intrigue, mix in a hint of cardamom or cinnamon to play with spice against the bitterness of the coffee.
Boozy Boost:
Brush the sponges with a little walnut liqueur or coffee liqueur (like Kahlúa or Tia Maria) before frosting. This adds a grown-up touch and keeps the sponge beautifully moist.
Crunch Factor:
Fold in toffee-coated walnuts or caramelized pecans into the batter or sprinkle them on top. It adds a delightful crunch and a hit of sweetness that complements the coffee.
Preserving the integrity of your coffee and walnut cake isn’t just about wrapping it up – it’s about locking in the moisture, texture, and flavor:
Pro Tip: For maximum freshness, freeze the cake unfrosted and add a fresh layer of icing after thawing.
