Marbled banana bread has swirls of cocoa through it which go great with the banana. This is a classic banana loaf with a little something special. Chocolate! Bursting with banana flavoured goodness, it's tastiest whilst still warm or once left for a few days for the flavours to develop further and the bread to go a little sticky. Made with a thick sweet batter full of mashed overripe bananas and swirled with a chocolate cocoa mixture to make fantastic marbled effect through the cake. A great cake tin standby for when friends pop over or just for something sweet to go with your cuppa. Next time you bake a loaf why not try a slice toasted with a little butter on it.
