Pourable Fudge Icing - cooking recipe

Ingredients

FUDGE ICING
1/2 cup white sugar
1/2 cup packed brown sugar
1/2 cup cocoa, plus
additional cocoa, to your liking
1/4 cup butter
1 teaspoon vanilla
1/3 cup half-and-half cream or 1/3 cup cream

Preparation

I had to make a double batch of fudge icing to get the right thickness of icing for this cake. The icing recipe I used was a combination of 2 different recipes.
In saucepan combine all ingredients. Bring to a boil, and cook for 1 minute Remove from heat. Whisk with an electric mixer, for 2.5 - 3 minutes, or until it thickens enough. Pour over cooled or warm cake. Doubled this for a 9x13.
