- Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan or line the bottom with parchment paper. 
- Mix the chocolate graham cracker crumbs and melted butter in a bowl. Press the mixture into the bottom of the prepared pan to form a crust. Pop it in the fridge to chill while you work on the filling. 
- In a large mixing bowl, beat the cream cheese until smooth. Add sugar and mix until fully combined. 
- Add eggs one at a time, beating after each addition. Stir in peppermint extract, vanilla extract, and food coloring if using. 
- Fold in the mini chocolate chips. 
- Pour the filling over the chilled crust and smooth the top. 
- Bake for about 55–60 minutes until the center is set but still slightly jiggly. 
- Turn off the oven, crack the door, and let the cheesecake cool inside for an hour. Then refrigerate for at least 4 hours (or overnight). 
- Before serving, top with whipped cream and crushed peppermint if you're feeling extra fancy.
