4 ounces unsweetened chocolate
1/2 pound unsalted butter, room temperature
4 cups powdered sugar
4 tablespoons milk
3 teaspoons vanilla
Melt chocolate in microwave, checking after each 30 second interval to make sure you do not burn the chocolate. Stir and let cool.
Using the paddle attachment on a Mixmaster or using a hand beater, beat the butter and chocolate together until smooth. Add 2 cups of the sugar and 2 tablespoons of the milk. Cream these ingredients until well blended. Add the rest of the sugar and the milk and combine. Add the vanilla and mix in.
