5-Minute Chocolate Cake

This just looks like fun. From the Reader's Digest , May 2012

Here's one more feat of microwave magic: gooey mug of cake, sized just right to satisfy an after-dinner craving.
1/4 cup flour
1/4 cup sugar
1/4 tsp salt
2 tbs unsweetened cocoa
2 tbs whisked egg
3 tbs milk
3 tbs oil
3 tbs chocolate chips or broken-up candy bar
Chocolate sauce or ice cream

1. Mix first four ingredients together in large coffee mug: add egg and combine until paste forms. Stir in milk an oil, then chocolate chips and vanilla.
2. Microwave on medium for 3 minutes until cake starts to crown over the top of mug. Remove, top with chocolate sauce or ice cream if desired, and enjoy.
