Microwave chocolate cake in a mug

For a few days now, I've been craving something sweet and decadent. I've finished our small tub of ice cream, which was sooooo yummy, and have taken to adding an extra bit of sugar to my daily coffee in an effort to assuage my sweet tooth. It worked for a little while, but then it hit me this past weekend that I wanted a chocolate cake! Unfortunately, baking a whole chocolate cake means I'll be munching on that all week, unlike having a mere spoonful per day of ice cream. I really just wanted one small slice and not have to worry about finishing the leftovers, causing me to completely ruin my diet.

Then I came across a cake recipe you can make in your mug using a microwave! It's perfect because it's a small portion that I can share with my fiance, it's fast and easy to make and it's made from scratch. Perfect! Previous recipes required using those powdered cake mixes, which I haven't used in a few years now and have no intention of using again.

The timing is also perfect as it is something I can make tonight for my fiance's birthday. Yay! Of course, it might turn out horribly since I've never made this before and there won't be any chance to tweak the recipe. Also, you should know that despite its small portion, it is by no means a low-calorie snack. In fact, the recipe below is for two servings, at about 400 calories per serving. Anyways, here's the recipe:

4 tbsp flour
4 tbsp sugar
2 tbsp unsweetened cocoa
1 egg
3 tbsp milk
3 tbsp vegetable oil
pinch of salt
pinch of baking powder
few drops of vanilla extract

Spray mug (recommend a really big one, like a big pyrex cup) with cooking spray, or rub a tiny bit of butter on the surface and sprinkle with flour. Mix all the wet ingredients separately from the dry ingredients. Add wet ingredients to dry and mix. Try not to over-mix. Pour into baking mug and place in microwave. Set the microwave for 3 minutes, but most likely the cake will be done before the time is up. Experiment a little and it's important not to overcook the cake.

Some changes I'll make to the recipe when I try it out tonight:
Add a pinch of instant coffee to enhance the chocolate flavor
Since I'm not sure if my baking powder is still good, I may have to replace it with baking soda and a drops of cider vinegar

If this turns out well, I might try replacing some of the oil with applesauce and/or replacing the egg with agar agar powder. Wish me luck!
