How to make a hummer shaped cake?

well, dont know how well it would work, but....get a rectangle cake pan (whatever size you want your "hummer") and bake your cakes...Then, stack two or three, one on top of the other. And then use cupcake molders to fill with cake and bake it, then, once its baked, take one of your cup cakes, and lay side ways...cutting off the top of cupcake, leaving the bottom half to use as tires. And then...just cover with frosting and use other stuff to decorate.|||That's a toughie! Good luck.|||Put wheels on a piece of pount cake you get from the supermarket
