In a blender or food processor, combine the cottage cheese and sweetener. Blend until smooth.
Break apart your cookie of choice and add it to the cottage cheese mixture. Pulse a few times to gently crush the cookies.
Pour the mixture into a small dish and smooth out the top.
Set the cheesecake cup in the freezer for a few minutes while you make the chocolate shell.
Melt three squares of dark chocolate by microwaving for 30 sec., stir, and repeat until smooth. (Or use a double broiler method over the stovetop)
Pour the chocolate on top of the cheesecake cup and place back in the freezer for 5 minutes until chocolate hardens.
Break through the chocolate shell and enjoy!
