Cream the greek yogurt and cream cheese together in a kitchen mixer. Then add in the eggs, egg whites, salt, vanilla, stevia & half of the cookie crumbles. Leave the protein powder to last and mix slowly.
Once mixed, spray a round non-stick pan with cooking spray and then pour your mixture into the tin. Sprinkle the remaining half of your cookie crumbles on top. Place your tin in a larger dish or baking tray filled with about an inch of water. This will cook your cheesecake with steam which helps prevent cracking.
Cook for 45 minutes. Increase the temperature to 300°F and cook for a further 15 minutes.
Remove from the oven. Allow to cool before transferring to the fridge for 2 hours.
