First, bake three circle cakes, two plain and one chocolate for the beef patty of the hamburger cake.

Using Vienna icing, make some light brown for the bun, dark brown for the beef patty and yellow for the cheese. Ice the bottom layer of the cake, then use thick green lollies to make a layer of lettuce on top. Then ice the beef patty and place it on top of the lettuce, use some icing in between the layers to stick them together.

Then use assorted lollies on top of this layer to represent the tomato, onion and pickles and use a layer of yellow icing for cheese. Ice the top layer and place it on top, sprinkle with silver cachous to represent seeds.

Place a skewer with a flag in the top and place on a fast food tray with other fast food items as shown.
