Done for a casual BBQ in honor of my Dad's 60th bday. I didn't even take time to put it on a cake board because it was so informal! LOL! The buns are yellow cake covered in fondant, which gave me a few problems due to the heat. The hamburger is a brownie. Fondant cheese, tomato, pickles, and lettuce. Buttercream ketchup, mustard, mayo, and sesame seeds. Was a HUGE hit...my Dad didn't even want to cut it. Thanks for all the tips I got here!
