In a large bowl, whip the heavy cream until stiff peaks form. Set aside.

In a medium bowl, cream together the powdered sugar and cream cheese until smooth. Add food coloring, vanilla extract, and peppermint flavoring, mixing until uniform. Fold in ½ cup of crushed peppermint candy.

Carefully combine the cream cheese mixture with the whipped cream using low speed.

Pour the combined mixture into the Oreo crust, spreading evenly.

Top with Cool Whip and sprinkle extra crushed peppermint. Chill in the refrigerator for 1-2 hours before serving.
