Preheat your oven to 340 degrees F, line a 9 inch pie dish with non stick spray and set aside.
Mix all of your crust ingredients together until well incorporated and spread evenly in your prepared pie dish. Bake crust for 12 minutes and set aside to completely cool.
In a large mixing bowl whisk your cream cheese until smooth and then whisk in your lime juice and sugar free condensed milk.
Whisk in your heavy cream and whisk until smooth and creamy. Add in your extra granulated sweetener if you would like pie a bit sweeter.
Pour your pie filling in your cooled crust and transfer into your fridge for at least 4 hours, but overnight is preferred.
Once your pie has set in the fridge, make your topping by whipping your cream and sweetener with a whisk and spread over top of your pie. Top with garnish if desired cut into equal pieces and enjoy!
