Practice Cake

I want to make a soccer ball cake for Ian's 3rd birthday. I bought all the stuff and decided to practice yesterday. It went pretty well but when I took the cake out of the mold, the tracing lines were no where to be found. So...I ended with a mound of very moist chocolate cake covered in frosting that in no way resembles a soccer ball. Guess I better try again and figured out what I did wrong. It could be the pan but it could be the recipe I used for the cake. I added sour cream and instant pudding to the cake mix and tasted like chocolate mousse. I loved it and so did Ian. I think some of it made it into his mouth. :)
