Jonas Brothers Cake

Alexandra is my little sister, and in honor of her 12th birthday we threw a surprise party for her, and boy was she surprised.  Hiding a cake this size from your sister who's house you were using to bake and decorate this cake is no easy task.  Luckily, the surprise went on without a hitch and everyone was able to enjoy the Jonas Brothers in cake form.
Cake is marble with buttercream frosting and buttercream fondant.
