Place the chocolate in a blender and blend to a powder consistency. Heat the half and half in a microwave in 30 second bursts until hot. Add the half and half and hot coffee to the blender and blend until smooth. Add the liquor and give the mixture a quick blend.
In a separate bowl, lightly beat the eggs. Add the eggs to the chocolate mixture and blend until well combined. Transfer the mixture to a large bowl and cool completely.
Whip the heavy cream until soft peaks form. Gently fold the whipped cream into the cooled chocolate mixture until well incorporated. Divide into individual ramekins and refrigerate for at lest 3 hours or overnight. Serve cold topped with fresh berries or additional whipped cream.
