Preheat the oven to 175°C. Combine Oreo cookie crumbs and melted butter until evenly moistened. Press the mixture firmly into the base of a 20x20 cm square baking pan, ensuring it stays only at the bottom and does not climb the sides. Bake for 10 minutes, then remove from oven and allow to cool slightly.

In a large bowl, beat cream cheese and sugar together until smooth and creamy. Add eggs one at a time, mixing well after each addition. Incorporate cocoa powder, melted dark chocolate, sour cream, vanilla extract, and salt, mixing until fully combined and silky. Avoid over-mixing.

Pour the cheesecake batter evenly over the pre-baked crust. Smooth the surface with a spatula. Bake at 175°C for 35 to 40 minutes or until the edges are set but the center slightly jiggles when lightly shaken. Turn off the oven and leave the cheesecake inside to cool for 20 minutes to prevent cracking.

Heat the heavy cream in a small saucepan until just simmering. Remove from heat and pour over the chopped dark chocolate. Let sit for 2 minutes, then stir gently until smooth. If lumps remain, microwave the ganache in 15-second intervals, stirring in between until fully smooth.

Remove cooled cheesecake from oven. Use a butterknife to loosen the edges and lift the cheesecake from the pan using the parchment paper overhang. Pour ganache evenly over the cheesecake and spread to the edges with an offset spatula. Optionally, sprinkle with chocolate pearls. Place in freezer for 10 minutes to set the ganache before slicing into 12 bars.
