Whist together (or use a small spoon) dry ingredients in a coffee mug. Add oil, water, & vanilla and mix thoroughly, making certain to scrape bottom and sides so that all is incorporated. If desired (DUH) mix in the Chocolate Chips.
Microwave on high 1 - 1 1/2 minutes. The finished product will be softish and chewy. Cool for 1 minute Eat right out of the mug (its GREAT with a scoop of ice cream too!).
