brown butter icing

Brown Butter Icing

½ cup (1 stick) unsalted butter

2 cups sifted confectioners' sugar

2 teaspoons pure vanilla extract

2 tablespoons milk, plus more if needed

Melt butter in a small sauce pan over medium heat, swirling pan occasionally, until nut brown in color, about 10 minutes. Remove from heat, and pour butter into a bowl, leaving any burned sediment behind.

Add confectioners' sugar, vanilla, and 2 tablespoons milk to brown butter; stir until smooth. If necessary, add more milk (up to 2 tablespoons) a little at a time, just until icing is spreadable. Use immediately.
