Preheat your oven to 350°F (175°C).
In a small bowl, combine 15g of rolled oats with one egg white. Mix until well combined to form a sticky crust mixture.
Press the oat and egg white mixture evenly into the bottom of a small, non-stick or lined baking pan.
Bake the crust for 8-10 minutes until set and lightly golden. Remove from the oven and set aside to cool slightly.
In a separate bowl, combine 200g of nonfat Greek yogurt, 50g of low-fat cream cheese, 15g of vanilla protein powder, a dash of stevia, and 1 teaspoon of vanilla extract.
Whisk or blend the filling mixture until smooth and creamy.
Pour the filling over the pre-baked crust, smoothing the top with a spatula.
Bake the assembled cheesecake at 300°F (150°C) for 15-20 minutes, just until the filling is set but still soft in the center.
Remove from the oven and let the cheesecake cool to room temperature, then refrigerate for at least 2 hours to fully set.
Serve chilled and enjoy your protein-packed, guilt-free dessert!
