2 Preheat the oven to 180°C/gas mark 4 and line a 12-hole muffin tin with paper cases. Sieve the flour and baking powder together into a bowl.
3 Place the eggs and sugar in a bowl of an electric mixer and whisk until pale and creamy. The mixture should double in volume and will take a few minutes. Once whisked, fold half the flour into the mixture.
4 Mix the coffee into the butter and pour half into the mixture. Add the remaining flour, then the rest of the coffee and butter and gradually fold in.
5 Divide the mixture between the paper cases and bake for 25 minutes until risen and a skewer comes out clean when inserted. Leave to cool for 5 minutes then turn out onto a cooling rack to cool completely.
6 To make the frosting, whisk the mascarpone with the icing sugar then add the Marsala. Pipe on top of each cupcake and give a generous dusting of cocoa powder. Finish by placing a few chocolate coffee beans on top.
