OK... so if you need a quick (very un-clean) chocolate fix... this chocolate cake in a mug will do the trick. Here is what you'll need...
4 Tablespoons flour (cake flour is really the best, but use all purpose in a pinch)
4 Tablespoons sugar
2 Tablespoons cocoa
2.5 Tablespoons milk
3 Tablespoons oil
2 teaspoons vanilla
Put all of the ingredients in a big mug and mix well with a fork. Microwave for 3 minutes and enjoy! Don't watch the microwave as it cooks, because you will want to STOP it if you see how the cake rises... but don't! Pour a little hershey's syrup over the top and enjoy... then go walk an hour on the treadmill! You can't have your cake and eat it too without a little exercise! =)
