Rich Espresso & Walnut Traybake

I don’t often drink coffee, having turned to matcha green tea for my daily buzz. However, one of the ways that I do readily enjoy our caffeine friend is in the form of a cake. The flavours bring back memories of my childhood – of being at a friend’s house, chatting to the parents and all the while eyeing up the cake sitting on the table next to the Bovril sandwiches and jar of sandwich spread!
