Instructions:

  1. Pulse the chocolate cookies in a food processor (or crush in a zip-top bag with a rolling pin) until finely ground.
  2. Combine the crushed cookies with melted butter.
  3. Press the mixture firmly into the bottom of the springform pan.
  4. Chill the crust for at least 30 minutes (preferably an hour).
  5. Preheat oven to 325°F (160°C).
  6. Wrap the bottom of the springform pan tightly in aluminum foil (to prevent leaks if using a water bath).
  7. Beat cream cheese and mascarpone cheese until smooth and creamy.
  8. Gradually add sugar and cocoa powder, mixing until well combined.
  9. Stir in vanilla extract and salt.
  10. Beat in eggs one at a time, mixing until just combined (avoid over-mixing).
  11. Stir in heavy cream.
  12. Gently fold in melted and slightly cooled chocolate.
  13. Pour the filling over the chilled crust.
  14. Bake for 60-70 minutes, or until the edges are set but the center still has a slight jiggle.
  15. Turn off the oven and let the cheesecake cool in the oven with the door ajar for 1 hour.
  16. Remove from oven and let cool completely at room temperature for another hour.
  17. Cover and refrigerate for at least 4 hours, or preferably overnight.
  18. Heat heavy cream in a double boiler (or microwave) until simmering.
  19. Pour the hot cream over the chopped chocolate.
  20. Let sit for 1 minute, then stir until smooth and glossy.
  21. Remove the sides of the springform pan.
  22. Pour the chocolate ganache over the top of the cheesecake.
  23. Smooth the ganache evenly.
  24. Chill for another 30 minutes to allow the ganache to set slightly.
  25. Slice and serve!
