4 1/2 ounces white chocolate, finely chopped
1 3/4 cups confectioners' sugar
1/4 cup milk
1/2 teaspoon vanilla extract
6 tablespoons (3/4 stick/3 oz./85g) unsalted butter, softened
Pinch of salt
1. Melt the white chocolate in a double boiler. Stir until smooth. Let cool to room temperature.
2. Sift the confectioners' sugar into a medium bowl. Stir in the milk and vanilla. Add the butter and salt and beat until smooth. Stir in the cooled white chocolate. Refrigerate until firm enough to frost the cupcakes, about 30 minutes.
Makes enough to frost 12 cupcakes.
