Cake in a Mug

Want to try something fun?

How about a homemade chocolate cake in a coffee mug... in 3 minutes?

Here is the recipe:
INGREDIENTS: hot chocolate mix, flour, an egg, cooking spray, and oil
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 and oil and one egg. Once it's thoroughly mixed into an even batter, microwave for three minutes - Viola!
