I used two yellow cake mixes for the "buns" and 3 boxes of Betty Crocker Brownies (9x13) size. I used a round cutter the size of the cupcake and got 15 "burgers" out of each pan. I made up some of my favorite Butter Cream frosting and divided it into three bowls and tinted them yellow for mustard, red for ketchup and green for lettuce. If I had more time I could have made fondant cheese and lettuce. Darn...maybe next time.
Tip: Cut the cupcakes in half first. Then with a pastry brush dipped in water, gently wipe over the top half of the cupcake and sprinkle on sesame seeds. Put aside to dry and assemble your burgers and use a frilly tooth pick to hold them together.
They came out so cute!!!
