Creating Chocolate Caramel Cheesecake involves several steps, all of which contribute to its outstanding flavors and texture. Follow these steps for successful results:

1. Preheat the Oven: Preheat your oven to 325°F (160°C).

2. Make the Crust: In a bowl, combine the chocolate cookie crumbs, granulated sugar, and melted butter. Mix until combined. Press the mixture into the bottom of a 9-inch springform pan to create an even crust.

3. Prepare the Cheesecake Filling: In a large mixing bowl, beat the softened cream cheese until smooth. Add the granulated sugar and vanilla extract, mixing until well combined.

4. Add the Eggs: Gradually add the eggs, one at a time, mixing well after each addition. Ensure everything is combined but avoid over-mixing.

5. Incorporate Sour Cream: Fold in the sour cream until just blended. Pour the cheesecake filling over the prepared crust in the springform pan.

6. Bake: Bake in the preheated oven for 50-55 minutes or until the edges are set but the center still has a slight jiggle.

7. Cool: Remove from the oven and allow it to cool at room temperature for about 1 hour.

8. Prepare Chocolate Layer: In a small saucepan, heat the heavy cream until it just begins to simmer. Remove from heat, and add the chocolate chips. Stir until the chocolate is melted and the mixture is smooth.

9. Layer the Chocolate: Pour the chocolate mixture over the cooled cheesecake, spreading it evenly.

10. Chill: Refrigerate the cheesecake for at least 1 hour to set completely.

11. Add Caramel Topping: Before serving, drizzle the top with caramel sauce and sprinkle with sea salt if desired.

Through these steps, you will successfully create a Chocolate Caramel Cheesecake that is bound to become a favorite dessert in your home.
