A Real Cup Cake

After reading this recipe for a cake microwaved in a mug (at Chasing Cheerios), I gave it a try last night.
  
It's fun, it's yummy, and it takes 5 minutes TOTAL.
  
MICROWAVEABLE CUP CAKE
  
In a bowl (or in a microwaveable mug, but I used a bowl in order to be able to stir it thoroughly),
  
Mix:
  
4 T. sugar
4 T. flour (all-purpose OR self-rising; there are recipes for both online -- I used all-purpose)
2 T. cocoa
  
Add:
   
3 T. milk
3 T. oil
1 egg
  
If you're like me, add the mandatory handful of nuts and chocolate chips.
  
Pour into a microwaveable mug (no need to grease) and nuke it for 3 minutes (1000 watt microwave, so you may want to watch your time). The cake rises and climbs up the mug, eventually mushrooming up over the top. It's pretty cool .
   
You can turn this over onto a plate and dust it with powdered sugar. A cherry on top makes it extra pretty.
  
I was thinking a fun idea would be to keep it in the mug and put whipped cream on top, so it looked like a mocha.
    
And if I had a camera cord, I'd show you!!! (Grrr...)
  
This is very fun and easy. So easy, in fact, that I'm going to have the kids do this on Monday for a Labor Day Treat. They'll get a kick out of watching it grow.
  
I'm thinking this is a good College Student Recipe, too, as you don't need an oven.
    
Try it and let me know what you think! Did you change it? What worked? What didn't?
