Preheat oven to 325F (163C).
Line the bottom of a 6" springform pan with parchment paper, and wrap the bottom of the pan in foil.
Rub coconut oil around the sides of the pan (or spray with cooking spray).
Make the crust by first mixing the almond butter and water until combined.
Mix in rice protein, cinnamon, and salt.
Press into the bottom of the springform, and set aside.
Chop the steamed apples, and sprinkle with cinnamon.
Lay about ⅓ of the apples over the crust. Mix the rest of the apples with the applesauce for the topping, and set aside.
Beat the Neufchâtel cheese and stevia until combined.
Add eggs and mix well.
Add yogurt and vanilla, and beat until smooth.
Add whey protein and cinnamon, and beat until smooth.
Pour batter over crust.
Place the springform in a water bath in the oven (put the springform in a larger pan with about 1 inch of water).
Bake at 325F (163C) for 30 minutes, then lower the oven to 200F (93C) and bake for 40-50 minutes more. The cake should be firm around the edges, but the center should be jiggly.
Remove from oven, and let cool at room temperature.
Refrigerate for several hours (cake will continue to set).
Top with apple mixture, and enjoy!
