Prepare the Crust:
Preheat oven to 325°F (160°C). Mix graham cracker crumbs, melted butter, and sugar until combined. Press firmly into a pie dish. Bake for 8–10 minutes, then let cool.
Make the Filling:
In a large bowl, beat cream cheese and brown sugar until smooth and creamy. Add eggs one at a time, mixing well after each. Stir in vanilla extract. Fold in chocolate chips.
Bake the Cheesecake:
Pour the filling into the cooled crust. Bake for 35–40 minutes, until the center is set but slightly jiggly. Remove and let cool at room temperature.
Chill:
Refrigerate for at least 2 hours (or overnight for best results).
Add Toppings:
Spread or drizzle chocolate ganache over the top. Add mini marshmallows and lightly toast them with a kitchen torch or broiler. Sprinkle cookie dough pieces and graham crumbs.
Serve:
Slice and serve chilled for the ultimate gooey, creamy s’mores dessert!
