UPDATE: I've changed this a bit. I have a few 3 month promemberships for getting featured on the homepage. Since I already have a pro membership, I am giving TWO away to the first two people who make these cupcakes and post pictures in the comments!
UPDATE: both 3 month pro memberships have been won. Congrats!

Step 1: Collect ingredients
-One 18.25 oz box of white or yellow cake mix
-4 eggs (instead of what is calls for on the box)
-1 cup butter milk (instead of water that is called for on the box)
-Vegetable oil (amount called for on the box)
Other stuff you will need:
Cupcake tin (this makes about 24 cupcakes)
1 can of frosting
sprinkles, or anything else you want to use to decorate
Step 2: Make batter
Mix all ingredients together in a large bowl. Mix with a hand mixer on low for 30 seconds until all ingredients are mixed, then mix on high for 2 minutes.
Separate batter into smaller bowls, one for each color that you want in your cup cakes. I had 5 smaller bowls for red, yellow, green, blue and purple.
