Homemade Chocolate Icing

My first try at homemade icing.  And I gotta say.  I rocked it.  I will never buy chocolate icing again.

You will need
1 1/2 cup powdered sugar
1/2 cup softened unsalted butter
1 teaspoon vanilla
2 Tablespoons milk
1/3 cup (or to taste) cocoa powder

I just used a large spoon but you could use beaters if you wanted.
Stir or beat powdered sugar and butter until smooth.  Add in the rest and stir or beat until well mixed.
Add more milk if it is too thick.
And that is it.  So Simple.  So Good.
I was able to cover two dozen cupcakes with this.
