Chocolate Buttercream Frosting

I haven't made home made chocolate frosting in ages so I looked up some recipes and came up with this one that I'm going to try.  I always used milk not cream but since we only have skim milk I might try some cream with this.

Chocolate Buttercream Frosting
Prep time: 2 mins
Cook time: 3 mins
Total time: 5 mins
Serves: 3 cups

A simple recipe for classic chocolate buttercream frosting. Perfect for frosting cakes, cookies, brownies, or cupcakes.

Ingredients
1 cup unsalted butter (2 sticks or 1/2 pound), softened (but not melted!)
3 1/2 cups confectioners (powdered) sugar
1/2 cup cocoa powder
1/2 teaspoon table salt
2 teaspoons vanilla extract or 1 teaspoon almond extract
4 tablespoons milk or heavy cream

Instructions
Cream butter for a few minutes in a mixer with the paddle attachment on medium speed.
Turn off the mixer.
Sift 3 cups powdered sugar and cocoa into the mixing bowl.
Turn mixer on the lowest speed (so the dry ingredients do not blow everywhere) until the sugar and cocoa are absorbed by the butter.
Increase mixer speed to medium and add vanilla extract, salt, and milk/cream and beat for 3 minutes.
If frosting needs a more stiff consistency, add a little more sugar.
If frosting needs to be thinned out, add additional milk 1 tablespoon at a time.
