Chocolate Buttercream

Ingredients:
2 cups (4 sticks) unsalted butter, room temperature
12 ounces semisweet chocolate, melted and cooled
3 T milk
1 1/2 teaspoons pure vanilla extract

Preparing the buttercream:
In the bowl of an electric mixer fitted with the paddle attachment, beat butter until smooth and creamy, 2 to 3 minutes. With mixer on low speed, add chocolate until just combined. Add milk, vanilla, and sugar; mix on medium until well combined, being careful not to overmix.
