Instructions
- Melt the butter in a saucepan and then add the brown sugar.
- Boil and stir for at least one minute.
- Take the saucepan off the heat and add the milk.
- With a hand mixer beat in the powdered sugar, one cup at a time until the spreading consistency is right for you.
- It should not be a very thick consistency for angel food cake, because it will harden as it cools.
