Brad's Coffee Cup Birthday Cake

My son is a coffee-a-holic, much like me. I saw this picture on the Wilton site, and decided I was going to make this for his birthday, but not tell him. When I asked what flavor of cake he wanted, he said can I have a white cake with the coffee buttercream icing. I could not believe that's what he asked for, especially when he had no idea of the cake I was going to make him. The cake tasted awesome, and really did have a coffee flavor because of the icing. So he had his cake and coffee too :)
