Preheat your oven to 325°F and lightly grease a 4-inch springform pan or oven-safe ramekin.
In a small bowl, combine the almond flour and melted coconut oil, then press the mixture firmly into the bottom of the pan to create an even crust.
Place the Greek yogurt, cottage cheese, egg whites, maple syrup, vanilla extract, and lemon zest into a high-speed blender.
Process the mixture until it is completely smooth and aerated, ensuring no lumps from the cottage cheese remain.
Pour the cheesecake batter over the almond crust and gently tap the pan on the counter to remove any air bubbles.
Bake for 35 to 40 minutes until the edges are set and the center has a slight, controlled jiggle.
Remove from the oven and allow to cool to room temperature before transferring to the refrigerator.
Chill for at least 4 hours, or overnight, to allow the cheesecake to firm up into a dense, New York-style texture.
