Wired’s how-to wiki gives us “Cake in a Mug,” perhaps the greatest thing to come to the microwave since peep jousting:
You’re working at home and your mind starts to wander to snack possibilities. There are probably some prepackaged, good-until-the-next-millennium baked items in your cabinet, but you’re in the mood for something warm from the oven. Something chocolate. However, your compulsion to work is just strong enough to keep you from leaving the computer long enough to make something from scratch. Guess it’ll have to be another stale Twinkie after all.
A single-serving portion of cake. Baked in a microwave. In the mug I mixed it in. Just for me. Right now.
Hello future. You can keep the jetpack.
