01 - Combine chocolate cookie crumbs with melted butter in a mixing bowl until fully moistened. Firmly press the mixture into a 9-inch pie dish to create an even crust base. Refrigerate while assembling the filling.
02 - In a separate bowl, whip the cold heavy cream using an electric mixer until stiff peaks form. Set aside.
03 - In a clean mixing bowl, beat softened cream cheese, powdered sugar, vanilla extract, and peppermint extract until the mixture is completely smooth and creamy.
04 - Gently fold the whipped cream, mini marshmallows, and crushed candy canes into the cream cheese mixture. For a festive appearance, gently swirl in red food coloring if using, until a light pink hue is achieved.
05 - Transfer the filling to the chilled crust. Use a spatula to spread the mixture evenly and smooth the surface.
06 - Cover the pie and refrigerate for a minimum of 4 hours, or until fully set.
07 - Just before serving, spread whipped cream over the set pie and garnish with extra crushed candy canes or peppermint candies for a decorative finish.
