Ingredients
- 8 tablespoons (1 stick) butter
- 1/2 cup packed light brown sugar
- 1/2 cup packed dark brown sugar
- 1/4 cup milk
- 2 cups confectioners’ sugar, sifted
- 1 teaspoon pure vanilla extract
Preparation
Step 1
Place the butter and brown sugars in a heavy medium-size saucepan over medium heat. Cook, stirring, until the mixture comes to a boil, about 2 minutes.
Add the milk, stir, and let the mixture return to a boil, then remove the pan from the heat. Add about 11/4 cups of the confectioners’ sugar and the vanilla.
Beat with a wooden spoon or whisk until the frosting is smooth.
Add 1/2 to 3/4 cup confectioners’ sugar, but not so much so that it thickens and hardens.
