Prepare the crust: In a mixing bowl, combine the crushed Oreo cookies and melted butter. Stir until the mixture resembles wet sand.
Form the crust: Press the Oreo mixture evenly into the bottom and up the sides of a 9-inch pie pan. Use the back of a measuring cup for an even layer. Place in the refrigerator to set while preparing the filling.
Make the filling: In another mixing bowl, beat the softened cream cheese with the powdered sugar and vanilla extract until smooth and creamy.
Whip the cream: In a separate bowl, whip the heavy cream until soft peaks form. Gradually add the peppermint extract while whipping until stiff peaks form.
Combine mixtures: Gently fold the whipped cream into the cream cheese mixture. Be careful not to deflate the whipped cream.
Fill the crust: Pour the peppermint cream filling into the prepared Oreo crust, smoothing the top with a spatula.
Chill: Cover the pie with plastic wrap and refrigerate for at least 4 hours or until firm.
Serve: Before serving, add a dollop of whipped cream on top and sprinkle with crushed peppermint candies for a festive touch.
Notes
Garnish with a few whole mint leaves for freshness and place a few additional crushed peppermint candies around the pie for an extra pop of color.
