Melt chocolate using a double broiler or in the microwave. Set aside and keep warm.

Pour Sambucca and 1/2 of cream into a large mixer with a whip attachment. Whip for 2 - 2 1/2 minutes on speed 3. You want to "under whip" the cream - no peaks and cream just begins to stick to sides of bowl.

Pour still hot chocolate quickly into the mixer.

Still on speed 3, whip until incorporated. Scrape bottom and sides.

Add remaining cream. Whip until incorporated on speed 2 for approximately 30 seconds. Scrape sides and whip on speed 3 for 1 minute. Do not overwhip cream and chocolate.
