Sate your afternoon sugar cravings with a dead-easy chocolate cake recipe that only requires hot chocolate mix, flour, an egg, cooking spray, and oil (all stuff you've got in your pantry anyway). Grab the biggest microwavable coffee mug you've got in your cupboard, and cover the inside with cooking spray. Mix up four tablespoons of flour and nine tablespoons of hot chocolate mix, then throw in three tablespoons of water, three tablespoons of oil and one egg. Once it's thoroughly mixed into an even batter, microwave the whole shebang for three minutes on high. Watch how high it rises from the cup in the video below:

When you hear that BEEEP of completion, you'll have yourself a piping hot, single-serving cake in a cup. In the name of research (ahem), I gave this a try myself this afternoon, and the result was—well, not the best cake I've ever had.
