Nothing goes better with a hot cup of coffee than a delicious piece of cake. But what if you have a Coffee and Walnut Cake? This recipe is fully infused with coffee from our Blue Coffee Subscription Box, and I think before you make your next pot of coffee, you need to try your hand at making this cake.

How to make the Best Coffee and Walnut Cake

For starters, you need to grab your ingredients for this cake. The list of star ingredients are —

For the Coffee and Walnut Cake

• 225g/8oz unsalted butter, plus extra for greasing
• 225g/8oz caster sugar
• 4 large eggs
• 50ml/1¾fl oz strong coffee (we recommend one of the coffees from our Blue Coffee Box)
• 225g/8oz self-raising flour
• 75g/2½oz walnuts

For the buttercream topping

• 125g/4½oz unsalted butter
• 200g/7oz icing sugar
• 50ml/2fl oz strong coffee (again, we recommend one of the coffees fro our Blue Coffee Box)
• 12 walnut halves or pieces, to decorate

Let’s Make a Coffee and Walnut Cake!

Preheat your oven to 180C/350F/Gas 4.

While your oven is heating up, mix together the butter and caster sugar.

Once your butter and sugar mixture is light and pale, add in your eggs one and a time, making sure that each egg gets mixed all the way in before adding in another one.

Once the eggs are incorporated well, now you are going to add in your strong coffee. Make sure that it is either room temperature or cold so as not to melt your butter or curdle your eggs.

Now, add in your flour and walnuts and mix to completely combine. Pour into two greased 8″ round cake pans. You can make this in a 13″x 9″ pan or even one large pan and make it a one layer cake, which you will then slice in half (which is what we did).

Transfer to the oven to bake 25-30 minutes, or until a skewer inserted into the centre of the cake comes out clean and the cake is golden-brown.

Remove the cake from the oven and leave to cool on a wire rack.

Let’s make the buttercream topping!

For the buttercream topping, beat the butter and icing sugar together in a small bowl until pale and light.

Add the espresso and mix well. The colour of the icing will change to a deeper cream colour. Now, spread the buttercream over the top of the cake and down around the sides.

Decorate the top of the cake with the walnut halves and serve in generous slices.
