Chocolate Buttercream

Melt the bittersweet chocolate and allow to cool slightly.

Place the butter or margarine salt and vanilla in a mixing bowl. Beat with a mixer until very light and airy about 4 minutes. Add the powdered sugar a little at a time while beating on low speed. Mix well and beat on medium speed for about 4 minutes. Add the eggs one at a time and beat for 5 minutes more. Add the melted chocolate and beat 4 minutes.
