For the Cheesecake
Preheat oven to 350F and place the Oreo pie crust on a baking sheet. Bake for 5 minutes once the oven is preheated. Set aside.
Add the cream cheese, pumpkin, Greek yogurt, vinegar, and food color to a large mixing bowl. (I used a stand mixer.) Mix until smooth.
Add the 3 scoops of protein powder, Swerve granular, and cocoa powder. Mix until smooth.
Add the mixture to the Oreo pie crust, spreading to its edges in an even layer.
Bake for 25-30 minutes or until the top layer starts to develop a slight crust (firm to the touch). There should still be some wobble. Remove from the oven to cool.
For the Frosting
Mix the cream cheese and light butter together before adding the Swerve confectioners and 1 scoop of protein powder. Mix until no lumps remain.
Add the frosting to the cheesecake once it's cooled for a few minutes.
Refrigerate the cheesecake for at least 4 hours (overnight is ideal). Refrigerate the leftover cheesecake or slice and freeze to extend its shelf life.
