Add the powdered sugar and beat again until any lumps are gone.

Carefully fold with a silicone spoon to mix together. You don't want to mix or stir here, because it'll deflate the whipped topping. Just gently fold it in.
Pour the cheesecake filling over the crust and smooth out. Cover with plastic wrap and refrigerate for at least 4 hours or leave over night.
Slice and top the cheesecake slices with whipped topping. Sprinkle crushed cinnamon graham cracker crumbs over top and serve.
