I just saw a Five Minute Chocolate Cake recipe on the Dizzy-Dee blog. Mix ingredients in a mug. Microwave on high for three minutes, plop out of the mug. It's perfect dorm food or midnight munchies fodder. Don't even think about the calories or fat. The taste is fine. The texture is a little rubbery. But hey, it's a chocolate cake serving in under ten minutes.
The only real downside is the appearance. Think "Two Girls, One Cupcake" :(
