Brown-Butter Glaze

Makes 1 cup
4 ounces (1 stick) unsalted butter
2 cups sifted confectioners' sugar
2 teaspoons pure vanilla extract
2 to 4 tablespoons whole milk
Directions
Heat butter in a saucepan over medium heat until golden brown, about 10 minutes. Carefully pour butter into a bowl, leaving sediment behind.
Add sugar, vanilla, and 2 tablespoons milk to butter, and stir until smooth. If glaze is too thick, add more milk. Use immediately.
