Diet Dr. Pepper Cake/Cupcakes

If you're anything like me, you'll be extremely skeptical of this recipe, just like I was.  It is called Diet Dr. Pepper Cake, and I made it in form of cupcakes, instead of cake.  For the frosting, I used low-fat cool whip.  These are DELICIOUS.  They are light, fluffy, and moist... and best yet, they are "low-fat", because instead of using oil/eggs/etc in your cake/cupcakes, all you add is the Diet Dr. Pepper.  Take my word for it, these are awesome.  I just randomly tried this recipe and thought if I didn't like them, that I'd throw them away, but instead I took the leftovers to work and all my coworkers loved them also.
Here's the recipe:

- 1 box of white cake mix
- 1 can of Diet Dr. Pepper

 Mix cake mix with Diet Dr. Pepper.  DO NOT add eggs/oil like the box says to.  Mix the 2 ingrediants together and bake according to box directions.  Top the cake/cupcakes with a low-fat frosting or cool whip.

Let me know what you think.  :)
