Creating the Heavenly Chocolate Cheesecake requires a few straightforward steps:

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

2. Make the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and granulated sugar. Stir until well mixed.

3. Press the Crust: Firmly press the mixture into the bottom of a 9-inch springform pan to form an even layer. Bake for 10 minutes, then remove and set aside to cool.

4. Prepare the Filling: In a large mixing bowl, beat together softened cream cheese and sugar until smooth. Add the vanilla extract and mix well.

5. Add Eggs: Gradually add eggs one at a time, mixing on low speed after each addition until barely combined. Do not overmix to ensure a smooth texture.

6. Incorporate Sour Cream: Gently fold in sour cream and melted chocolate until no streaks remain.

7. Pour the Filling: Pour the cheesecake filling over the cooled crust, spreading it evenly.

8. Bake the Cheesecake: Place the pan in the preheated oven and bake for 60 minutes, or until the edges are set, but the center is still slightly jiggly.

9. Cool the Cheesecake: Turn off the oven, crack the oven door, and allow the cheesecake to cool completely in the oven for about 1 hour. Afterward, chill the cheesecake in the refrigerator for at least 4 hours or overnight.

10. Make Ganache: In a small saucepan, heat heavy cream until just simmering. Remove from heat and add chocolate chips. Stir until smooth and glossy.

11. Top with Ganache: Pour the ganache over the cooled cheesecake, spreading it evenly. Let it set in the fridge for about 30 minutes.

12. Decorate: Top with whipped cream, chocolate shavings, or fresh berries if desired before slicing.

These steps ensure a rich, creamy cheesecake that you and your guests will love. With a bit of patience, you’ll be rewarded with a dessert worthy of any celebration!
