2 c. sugar
1/2 c. cocoa
1 stick butter
1/2 c. milk

Bring to a boil and keep boiling for 2 to 3 minutes. Then add 1 teaspoon vanilla and remove from stove; cool to lukewarm. (Put in the refrigerator for a few minutes to speed cooling.) After cooling, use mixer to beat to your preferred consistency. Then pour over your cake or brownies.

I use Duncan Hines yellow cake mix (the one that needs a small box of instant vanilla pudding mix added).

Bake cake in a Bundt pan.
