In a large mixing bowl or stand mixer, beat cream cheese until fluffy.

Add Greek yogurt, vanilla extract and peppermint extract; mix until well combined. Add salt and protein powder and mix until well combined. Fold in half the candy cane pieces.

Spread mixture into prepared pie crust. Sprinkle remaining candy cane pieces on top. Cover and place in the freezer for 2 hours, or until set.

Let thaw a few minutes at room temperature before cutting into slices and serving.
