1. Prepare the Crust:

1. In a bowl, mix chocolate cookie crumbs and melted butter until combined. Press firmly into the bottom and sides of a 9-inch pie dish. Chill in the refrigerator for 15 minutes.
2. In a large bowl, beat cream cheese and sugar until smooth. Add peppermint extract and a few drops of green food coloring (if using), mixing until well combined.
3. In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
4. Stir in mini chocolate chips, then pour the filling into the chilled crust. Smooth the top with a spatula.
5. Refrigerate for at least 4 hours or until set. Garnish with whipped cream and chocolate shavings before serving.
