As an adult (at least some think so), I still love the patterns in a marble cake. The anticipation of cutting the first slice to see how the marbling has turned out is joy that makes me feel like a little girl again. A good marble cake for me has to be moist, with lovely chocolate and vanilla swirls where you can taste their flavours separetely and not excruciatingly sweet. With this one however, I had a coffee swirl too. The flavour cushions of vanilla and chocolate ensures the coffee one is quite safe. As with any marble cake you simple divide the batter into two and mix cocoa into one half and then pour them into a baking tin before you swirl it with a knife or as in my case, a chopstick.
