Coffee and walnut cake is a flavour combination made in heaven and for a coffee lover like me, it's win win!
A classic cake that shouldn't be messed around with too much and one, that for me, still has it's place in a coffee shop, regardless of how 'too cool for school' they are.
I've made this cake with instant espresso powder which can be found at the supermarket, the cake is made with a mixture of butter and margarine which produces a lighter sponge.
