01 - Combine chocolate cookie crumbs with melted unsalted butter in a medium bowl until evenly moistened. Press mixture firmly into a 9-inch pie dish to create an even crust layer. Chill in the refrigerator while preparing the filling.
02 - Using an electric mixer, beat the cold heavy whipping cream in a large bowl until stiff peaks form. Set aside.
03 - In a separate bowl, beat softened cream cheese, powdered sugar, vanilla extract, and peppermint extract together until mixture is smooth and creamy.
04 - Gently fold the whipped cream, mini marshmallows, and crushed candy canes into the cream cheese mixture. For a festive color, swirl in a few drops of red food coloring if desired.
05 - Evenly spread the candy cane filling into the chilled crust. Smooth the surface with a spatula.
06 - Cover the dish and refrigerate for at least 4 hours, or until the filling is fully set.
07 - Before serving, top with whipped cream and sprinkle with additional crushed candy canes or peppermint candies.
