Preheat the oven to 325°F (160°C).
Make the crust: Combine graham cracker crumbs, melted butter, and ¼ cup sugar. Press into the bottom of a springform pan. Bake for 8–10 minutes, then cool.
Prepare the filling: Beat cream cheese and sugar until smooth. Add vanilla and eggs one at a time, mixing after each. Stir in sour cream and chocolate chips.
Bake the cheesecake: Pour filling over crust and bake for 55–60 minutes, until the center is slightly jiggly but edges are set.
Cool gradually: Turn off the oven, crack the door, and cool for 1 hour.
Chill: Refrigerate for at least 4 hours or overnight.
Finish and serve: Drizzle with caramel sauce, sprinkle sea salt, and garnish with whipped cream and mini chocolate chips.
