Choc cake in a Mug

I ran across this recipe while surfing, and I thought it might be worth a try…

"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 thang for three minutes on high."
