Chocolate Buttercream Icing - cooking recipe

Ingredients

1 1/2 cups semi-sweet chocolate chips
1/2 cup butter, room temperature
2/3 cup milk
1 teaspoon vanilla
1/2 - 2/3 cup confectioners' sugar

Preparation

Combine the chocolate and butter in a small heavy saucepan and melt over very low heat.
Remove the pan from the heat, stir in the milk and vanilla, and transfer the mixture to a mixing bowl.
Add the sugar gradually, beating with an electric mixer. Continue beating until the mixture is smooth--it will be runny.
Refrigerate the mixture for 1 hour, beating every 15 minutes. (The icing will stiffen.).
