20 Second Sugar Free Chocolate Mug Cake

I found this recipe online at http://www.pbs.org/food/fresh-tastes/microwave-chocolate-cake/ but modified it to be sugar free for me (and it is flourless). I combined the two serving recipe to make a wopping one serving chocolate cake that is only 92 calories! I am posting the recipe below. You can do a search under food and enter 20 second mug cake and get the full nutritional information.
• 1 egg – beaten- 70 calories
• 1/2 tsp. vanilla extract- 6 calories
• 1 tbsp. Fat free milk- 6 calories
• 1 tbsp. cocoa powder- 10 calories
• 2 tablespoons sugar free Splenda- 0 calories
• 1/4 tsp. baking powder- 0 calories
1. Add the Splenda and cocoa powder to a small bowl. Add the fat free milk, egg and vanilla and whisk until there are no lumps. Sprinkle the baking powder on top and quickly mix together.
2. Split the batter between the two mugs and firmly tap the mugs on a towel-lined countertop to release any large air bubbles. Microwave one cake at a time.
3. Since you don’t want to start and stop the microwave a bunch of times, set it for about 40 seconds, and closely watch the cake. It’s done when the cake rises about half-way up to sides of the mug (about 20 seconds in a 1000 watt microwave). The difference between a tender fluffy cake draped in velvety chocolate sauce and a chewy hockey puck is a few seconds, so you'll need to experiment to see what works best for your microwave.
You can also spread with peanut butter (1 tbsp.) for only 80 calories more. I added some expresso powder (1/4 tsp.) to mine and it was yummy!!!
