Ingredients (Add them to your next week’s shopping list)

Base Cake:

• 225g of unsalted butter, softened
• 225g of caster sugar
• 4 eggs, large and beaten
• 4 to 6 tablespoons of strong, freshly brewed coffee (or 1 tbsp of instant coffee, mixed with 1 tbsp of boiling water)
• 225g of self-raising flour (try our organic unbleached variety)
• 75g of chopped walnuts

Coffee Buttercream:

• 175g of butter, softened
• 300g of icing sugar
• 1 to 3 tbs very strong freshly brewed coffee (or 3 tbsp of instant coffee, mixed with 1 tbsp of boiling water)
• 50g of walnuts
• 12 walnut halves

Instructions (the magic is in the detail)

1. Start with care
Preheat the oven to 180°C (gas mark 4). Grease and line two 20cm sandwich tins—getting everything ready now makes the baking feel calm and enjoyable.

2. Create a light, fluffy base
Cream the butter and sugar together until pale and fluffy. Take your time here—this is what gives the cake that soft, bakery-style texture.

3. Build the mixture gently
Add the beaten eggs a little at a time, along with a tablespoon of flour to prevent curdling. Beat well between each addition until smooth.

4. Add the flavour
Fold in the remaining flour, along with the coffee and walnuts. The aroma at this stage is already a hint of what’s to come.

5. Bake to perfection
Divide the mixture between the tins and bake for 20–25 minutes, until risen and golden. Let them rest briefly before turning out onto a wire rack to cool.

6. Make the buttercream filling
While the cakes cool, beat the butter and icing sugar until pale and fluffy. Add the coffee and chopped walnuts, mix well, then chill for 15–20 minutes to firm up.

7. Assemble with love
Once the cakes are completely cool, sandwich them together with half the buttercream. Spread the rest over the top and decorate with walnut halves.

It’s the kind of cake that feels thoughtful without being overcomplicated—and that’s often exactly what makes special occasions memorable, especially for the coffee-lovers!
