The buns, cheese, lettuce, and tomatoes are all MMF. I cut and shaped them, trying to match to the size of the cake. The patty is chocolate cake. The ketchup is red icing that I thinned a little and "squirted" on using a Wilton condiment bottle. I just left what I didn't use sitting beside the finished cake to appear as the ketchup bottle. This turned out a little bigger than I wanted, but it was my first cheeseburger and 3-D cake, so I will do better if I ever make another one.
