A very adult cupcake perfect to celebrate National Cupcake Week, though watch the kids as they will like them too.
1. Preheat the oven to 190C, 375F, Gas mark 5 and place 12 paper fairy cake cases on a baking tray, evenly spaced apart.
2. Mix the coffee with just enough boiling water to dissolve then place in a large mixing bowl together with the remaining cupcake ingredients and beat with a wooden spoon until well blended. Using an electric hand whisk makes mixing easier and quicker.
3. Divide the mixture between the paper cases, no more than 2/3rds full, smooth the tops, then bake towards the top of the oven for 12-15 minutes, until well-risen, golden and firm to the touch. Cool on wire racks.
5. Once the cupcakes are cold, mix the instant coffee with the hot water in a small bowl to dissolve then add the icing sugar and beat together until well blended and smooth.
6. Place a teaspoon of glacé icing over the top of each cupcake, smoothing with the back of the spoon, immediately sprinkle with chocolate hundreds and thousands or cocoa powder using a sieve, and allow to set before serving.
