In a small bowl, combine the heavy cream and dark chocolate morsels.
Microwave on low for 30 seconds at a time, stirring in between, until melted.
Whisk the chocolate until smooth and then pour it over the top of the cookie dough filling.
Use a spatula to evenly spread the mixture.
Return to the refrigerator to cool for another 1-2 hours.
Remove the bars from the pan by lifting them out with the parchment paper.
Cut bars using a long sharp knife. Store leftovers in the refrigerator.
