01 - Combine chocolate cookie crumbs and melted butter in a medium bowl. Mix until evenly moistened, then press firmly into a 9-inch pie dish to form an even layer. Refrigerate while preparing the filling.
02 - In a large bowl, using an electric mixer, beat heavy whipping cream to stiff peaks. Set aside.
03 - In a separate bowl, beat softened cream cheese, powdered sugar, vanilla extract, and peppermint extract until smooth and creamy.
04 - Gently fold the whipped cream into the cream cheese mixture, then incorporate mini marshmallows and 1/3 cup crushed candy canes. For a festive color, swirl in a few drops of red food coloring if desired.
05 - Spoon the filling into the chilled crust, smoothing the surface with a spatula.
06 - Cover and refrigerate for at least 4 hours, or until the filling is firm and set.
07 - Just before serving, garnish with whipped cream and additional crushed candy canes.
