Beat the butter with the sugar. Add the eggs and continue beating. Mash the bananas and add them to the mixture. Keep beating until all the ingredients come together into a smooth, compact batter.

Stir the baking powder, salt and cinnamon into the flour and mix thoroughly. Combine both parts of the batter together to make a fragrant dough.

Add whatever extras you fancy. We went for coconut flakes and roughly chopped chocolate. Various nuts work great too - pecans, for instance.
