Preheat oven to 250'F.
Using a hand mixer, beat cream cheese until smooth.
Add yogurt, eggs, and egg whites and continue mixing until smooth.
Add sweetener and protein powder and mix until fully incorporated.
Stir in vanilla
Lightly grease a 9" round glass pie dish and pour in batter.
Bake in preheated oven for 25 minutes.
After 25 minutes, leave cheesecake in the oven and increase the oven temperature to 350'F. Continue baking another 20 minutes for a total of round 45 minutes. Cheesecake is done when the center appears set.
Meanwhile, make the topping. Boil water and add monk fruit.
Reduce heat to medium-high and stir until monk fruit is dissolved.
Add frozen berry blend and stir. Reduce heat to medium-low and simmer until berries have begun to break down.
Remove from heat. Compote will thicken as it sets.
When cheesecake and topping have both cooled to room temperature, spread berry compote over the top. Store in the refrigerator for a week.
