Holy crap. That's huge!One year my son & his friends made these at his birthday party. Used white cake for each of the buns, chocolate cake for the burger (spring form pans), rice krispie as sesame seeds, sliced green gum-drop thingies for the pickles, red/yellow/white icing for ketchup/mustard/mayo. Was a great deal of fun. They each made & ate their own cakes for dinner, then also for breakfast. I'm sure their moms appreciated me returning them loaded with sugar.This one looks like it has green fruit roll-up as lettuce. That's a good idea too. (Image removed from quote.)
