Butter Cream Frosting

I had a bunch of people coming over to watch a football game, and decided to make some cupcakes. I'm not a huge fan of the frosting in a tub, so I went on a search on the Internet for a butter cream frosting, since that's the ingredients I had on hand. If found this one:

Butter cream Frosting:

4 cups powdered sugar

1 teaspoon vanilla
4 tablespoons milk

1/2 cup shortening

1 1/2 cups butter

Cream all ingredients together. Add food coloring if desired.

I halved the recipe and it was enough to cover 24 cupcakes. I'll be using this again, I'm replacing the tub frosting forever!
