Master K turned 15 yesterday! We made him a chocolate layer cake. The recipe I chose was Black Magic Cake, which I found on allrecipes.com but which probably originally came from Hershey's. The batter is frighteningly thin but the cake turned out great. I think the addition of the coffee is what makes the difference.
For icing, I made this frosting, only after adding 2 tablespoons of milk as it said to, the icing was still a clumpy, dry mess. I added some more cold coffee to thin it and to echo the coffee in the cake. I'll do that again for sure.
