Stephanie asked me for a hamburger birthday cake so off to Google I went to look up ways to do it. I baked two cakes, one yellow and one devil's food. I coated the "hamburger patty" with vanilla icing mixed with cocoa powder, then stuck chopped chocolate chips to the icing. I colored the icing for the "lettuce", the "bun", and the "sesame seeds" and proceeded to assemble it. I found that I should have put the bun icing on the bottom layer before stacking the patty on it. Live and learn. It tastes better than it looks.
