Melt chocolate in a double broiler over simmering water for 5 to 10 minutes, stirring occasionally. Once smooth and thoroughly melted, remove from heat and allow it to cool to room temperature.

Add melted chocolate, increases speed to medium, and whip for 2 minutes. Be sure to scrape the sides of the bowl as needed. Add vanilla and beat for another 3 minutes.
Reduce speed to low and gradually add in powdered sugar. Whip until fully incorporated, then increase speed to medium. Whip until desired consistency is reached, about 2 to 4 minutes.
