In a medium bowl add ¾ cup heavy cream (reserve the 2 Tbsp for later) and use a hand or stand mixer to whip into stiff peaks. Set aside.
In a small bowl, add ⅔ cup white chocolate chips, and 2 Tbsp heavy cream. Microwave in 20-30 second increments, stirring between each increment until white chocolate has formed a ganache. Set aside.
In a separate large bowl, add 4 oz cream cheese and ¼ cup powdered sugar and beat with a hand or stand mixer for 1-2 minutes or until smooth.
Add in the 1½ tsp vanilla, ½ cup greek yogurt, and white chocolate ganache made in the first step of the filling, Blend together until smooth and evenly combined.
Chop up the remaining 10 double-stuff oreos and add to the filling. Carefully add in the reserved whipped cream and gently fold together until no more streaks of whipped cream remain and the cookies are evenly distributed.
Pour the filling into the cooled pie crust and smooth out the top with a spatula. Allow to set in the refrigerator 4-6 hours or until fully set;
