Cupcakes are they key to anyone’s heart, especially when they’re chocolatey and miniature!
Preheat the oven to 200C, in a large mixing bowl place the sugar and margarine and beat. Add the eggs, beat until combined, fold in the flour and cacao powder, pour in the milk and fold.
Line a cupcake/muffin tray with cupcake cases, spoon the cake mixture inside and bake for 10 to 12 minutes or until cooked through. Leave to cool completely.
Mix the butter and icing sugar together in a bowl until fluffy, pour in the melted chocolate, beat until smooth, transfer to a piping bag and pipe on to the cool cakes. Decorate with sprinkles (optional).
