In a small bowl, process the Greek yogurt and heavy cream with a stick blender. Add light cream and process until mixture is the consistency of thick pancake batter. Add sugar if using.

In a separate bowl, process the strawberries until pureed.  Add mint if using.

Into each popsicle mold, add about 2 tbs of the yogurt mixture, then add about 1-2 tsp of the strawberry puree.  Repeat, ending with a yogurt layer.

Add sticks (if your pop maker requires them) and freeze for at least 6 hrs, preferably overnight.
