My son needed a cake for his Blue & Gold Banquet, so this is what we came up with. I was actually shocked at how this turned out, being that it was my first "real" cake and first time with fondant. The top bun was made in a pyrex glass bowl. The bottom & burger are just round pans. The seeds are the big rice krispies cereal. The burger was chocolate buttercream with crushed cookies layered on. The "toppings" we all made from fondant except for the ketchup & mustard which were buttercream.
