I've made this recipe so many times now, there are always over-ripe bananas in my fruit bowl. The blacker the banana, the lighter the sponge will be. My favourite cupcakes are always going to be the ones topped with chocolate flake, even though some of them were decorated with chocolate eggs. The puddle of chocolate on top of the cupcakes is a mixture of dark chocolate and unsalted butter gently melted together.The recipe is from one of my favourite food writers Annie Bell who is the principal cookery writer for YOU Magazine. I always tear out the recipe section from the magazine and tuck them away in my Annie Bell cookery books for future use.
