Aunt Hack's Chocolate-Orange Frosting

I recently made/modified a family frosting recipe.  Chocolate-orange frosting can't be beat.

Ingredients:

-8 oz. butter, soft

-8 oz. 10x sugar

-zest and juice of 1 orange

-cocoa powder to taste

-pinch salt

1. Cream all ingredients in a mixer until fluffy and use to frost immediately.

It's perfect on a dark chocolate cake.  With a name like "Hack" it has to be good.
