Preheat your oven to 375°F and line the bottom of a 7-inch springform pan with parchment paper. Lightly grease the sides so the cheesecake releases easily later. Wrapping the outside with foil also helps during the water bath process.
Add crushed graham crackers, almond butter, and maple syrup into a food processor. Blend until crumbly and evenly combined, then stir in the egg white. Press the mixture firmly into the bottom of the pan using the back of a spoon.
Place the crust into the oven and bake for about 10 minutes until lightly golden. Once baked, remove it from the oven and allow it to cool completely. A cooled crust prevents the filling from becoming soggy.
Add the cottage cheese to a blender or food processor and blend until completely smooth. This step is extremely important because cottage cheese curds can create a lumpy cheesecake texture if not blended properly.
In a large bowl, beat the softened cream cheese until airy and fluffy. Add the blended cottage cheese and almond milk, then mix again until smooth. Stir in the protein powder, cornstarch, vanilla extract, and finally the egg.
Mix the batter only until the ingredients are combined. Overmixing introduces too much air, which can cause cracks while baking. The batter should look creamy and smooth without being overly whipped.
Place the springform pan inside a larger baking dish filled with 2 to 3 inches of hot water. This water bath method helps the cheesecake bake evenly and prevents the top from drying out or cracking.
Reduce the oven temperature to 350°F and bake the cheesecake for about 30 to 35 minutes. The edges should look set while the center remains slightly jiggly when gently shaken.
Remove the cheesecake from the oven and let it cool completely at room temperature. Once cooled, refrigerate it for at least 2 hours so the texture firms up properly before slicing.
