To make the cheesecake, in a high-powered blender, combine all of the ingredients and blend for about 3 minutes, or until the mixture is silky smooth and creamy. You may need to add a bit more coconut milk or lemon juice to get it to blend smoothly if your blender isn’t super high-powered. Taste the mixture and adjust the sweetness or tartness if needed.
Pour the filling over the crust and s with a rubber spatula. Tap the pan hard against the counter to release any air bubbles.
Place it in the freezer to set for 2-3 hours or until completely firm before serving.
