Preheat oven to 325°F (160°C). In a medium bowl, mix graham cracker crumbs with melted butter until combined. Press firmly into the bottom of a 9-inch springform pan.
In a large bowl, beat cream cheese and sugar until smooth. Add eggs one at a time, beating after each addition. Stir in vanilla extract.
Pour half of the cheesecake batter over the crust. Drizzle half of the caramel sauce and sprinkle half of the chopped pecans and melted chocolate chips. Pour remaining batter on top and repeat caramel, pecan, and chocolate layers.
Bake for 55-60 minutes or until the center is almost set. Turn off oven and leave cheesecake in oven for 1 hour with door slightly open.
Remove cheesecake and chill in refrigerator for at least 4 hours before serving. Drizzle with additional caramel sauce if desired.
Notes
To enhance flavor, use homemade caramel sauce and lightly toast pecans before adding them to the cheesecake.
