Mocha Cupcakes

dan's birthday is tomorrow. the girls helped me make these cupcakes this afternoon for his party tomorrow night. they are made with chocolate cake and coffee icing. i just used the same chocolate cake recipe that i always use. here's the coffee icing recipe...

...recipe my own creation
3 tablespoons instant espresso powder
1 tablespoon hot water
1 stick butter, softened
3 cups powdered sugar
a little bit of milk

Dissolve the espresso powder in the hot water. Set aside.
In a mixer beat the butter until soft. Add the powdered sugar and the espresso mixture a little at a time, alternating back and forth. If needed add a little milk at the end to thin the icing a bit.
