Creating the Black Forest Cheesecake Symphony can be effortless if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 325°F (160°C). Grease a 9-inch springform pan with butter or non-stick spray.

2. Make the Crust: In a medium bowl, mix chocolate cookie crumbs, melted butter, and granulated sugar until combined. Press this mixture firmly into the bottom of the prepared springform pan.

3. Prepare the Cheesecake Filling: In a large mixing bowl, beat softened cream cheese and granulated sugar using an electric mixer until the mixture is smooth and creamy.

4. Add Eggs: Gradually add eggs to the cream cheese mixture, one at a time, mixing well after each addition. Make sure the mixture is well combined and smooth.

5. Incorporate Other Ingredients: Stir in vanilla extract, sour cream, heavy cream, and cocoa powder until fully incorporated. This will add a delightful chocolate flavor to the cheesecake.

6. Pour Filling: Carefully pour the cheesecake filling over the crust in the springform pan, smoothing the top with a spatula.

7. Bake: Place the cheesecake in the preheated oven and bake for 40-45 minutes. The center should appear slightly jiggly and firm around the edges.

8. Cool and Chill: Once baked, remove the cheesecake from the oven and let it cool in the pan for about 30 minutes. Then, cover it and refrigerate for at least 4 hours or overnight to set.

9. Prepare the Topping: In a separate bowl, whip heavy cream with powdered sugar until soft peaks form. Be careful not to overwhip.

10. Assemble: Once the cheesecake is thoroughly chilled, spread a generous layer of whipped cream on top. Spoon the cherries over the whipped cream, allowing some of the syrup to drizzle down the sides.

11. Garnish: Finish with dark chocolate shavings over the top for an elegant touch.
