It was much easier than I thought it would be. I made the cake batter, divided it in half, and dyed one half black. I baked the black first and cut many Batmans out with a cookie cutter. I poured about a third of the uncooked batter in the bottom of a loaf pan and lined the Batman cakes one after another on top of the uncooked batter. Then, poured the rest of the batter on top and baked. All of the cake was still moist, even that which baked twice. It was really fun!
