I was asked to make a beer pong cake for my bro-in-law. I made one regular sheet cake and topped with a smaller cake. I bought mini plastic cups, beer cans and Batman toy at local stores.
I made the ball, covered figurine (to make him look like my bro-in-law) and cups with fondant, filled up cups with yellow icing for beer. Came out better than I expected. Bro-in-law loved his happy Beer day cake.
