- 2 cups unsalted butter
- 1 pinch salt
- 2 eggs
- 4 cups confectioners' sugar
- 1 teaspoon vanilla extract
- 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 melted chocolate, and beat 4 minutes.
