Stir in the chocolate
Mix in the heavy cream, stirring just until the dough begins to come together.

Lightly knead the dough two to three times, just to further mix the ingredients together.
Place on a very lightly floured surface and pat out into a circle. Keep dough approximately one inch high.
Use a three inch biscuit cutter and cut out biscuits. Place on a baking tray covered with a silicone baking liner or on a lightly greased baking tray.

Brush the surfaces of shortcakes lightly with additional heavy cream.
