The best chocolate buttercream recipe contains dark chocolate. But maybe we're biased?

Dark Chocolate Buttercream

In a large mixing bowl, beat butter with electric mixer on medium to HIGH speed for 30 seconds. Gradually add powdered sugar and cocoa powder; beat on LOW until combined.

Slowly add whole milk and vanilla extract. Beat on medium until light and fluffy. If desired, beat in 1 to 2 tablespoons additional milk for a smooth and creamy consistency.

Spread frosting on your favorite cake, cupcake, or cookie.
