What are smash cakes?
@fcabanski: found this description:
Most first birthday parties are celebrated with a cake, but smash birthday parties boast two cakes, a large cake and a single serving cake. The large cake is for the adult guests, and the second cake is for the guest of honor. Whereas guests eat their cake by the slice and usually employ a fork, your child will have a cake all to himself, no fork required. Once presented with his sweet reward, he's encouraged to attack it with his fingers, fists or face. This table-manners-be-darned approach results in a face full of frosting and cake crumbs, cake covered fingers and cake on the floor. It also inspires grins all around. 4951
