Preheat oven to 350 degrees F. Combine crust ingredients together in a bowl and stir well until combined. Spread onto a parchment-lined, 8-by-8-inch baking dish.
Combine all cheesecake ingredients in a stand mixer, or use an electric mixer on medium speed, until smooth and well incorporated. Taste and adjust stevia if needed. Spread the cheesecake filling over the crust evenly.
Mix the topping ingredients together in a small bowl, then sprinkle mixture over the cheesecake. Bake for 30 minutes, then chill 3-4 hours to set or overnight. Top with sugar-free caramel sauce, if desired.
