Makes one 6-inch cheesecake.
A note about substitutions: because each type of protein powder has a distinct flavor and texture when baked, I would not try substituting different types of protein powders in this recipe. You may substitute other natural sweeteners for the agave nectar, if you like. If you use a granulated (dry) sweetener, you may need to lessen the bake time (check after 40 minutes at 200F). And because this recipe is baked, regular vanilla extract should be fine.
