Preheat the oven to 170C/325F.
In a mixing bowl, add your crushed cookies, sweetener, and melted butter and whisk together until combined. Transfer into a greased 8-inch springform cake pan.
Add the cheesecake filling ingredients into a high speed blender and blend until smooth. Transfer onto the cheesecake crust.
Place the cheesecake in the oven and bake for 45-55 minutes, or until the middle is set.
Remove the cheesecake from the oven and let it cool completely, before refrigerating for at least 4 hours, to firm up.
