Aunt Pittypat'S Caramel Icing - cooking recipe

Ingredients

1 1/2 cups dark brown sugar, firmly packed
1 1/2 cups granulated sugar
1 1/2 cups milk
2 tablespoons butter

Preparation

Combine sugars and milk and bring to the boil, stirring gently.
Boil without stirring, until a little mixture forms a very soft ball when dropped in cold water.
Add butter, remove from heat and cool until lukewarm.
Beat at medium speed until thick, creamy, and of a consistency to spread.
If necessary, place over hot water to keep soft while spreading, or beat in a little milk.
This will fill and frost a 2-layer 9 inch cake.
