Buns are 2- 8" round peanut butter cakes with peanut butter icing. Burger patty is an 8" round brownie. Bacon, pickles, tomatoes, & cheese are rolled fondant. Lettuce,ketchup & mayo are buttercream. Sesame seeds are rice cereal. Fries are sugar cookies. My first time using fondant. My boyfriend loved it for his bday and I had a lot of fun!
