Instructions
 

  • Prepare Brownie Base:
  • Preheat oven to 325°F (163°C). Line the bottom of a springform pan with parchment paper. In a bowl, whisk melted butter, sugar, eggs, vanilla, and then add cocoa, flour, salt, and baking powder. Pour into pan and smooth evenly.
  • Bake Brownie Layer:
  • Bake for 20 minutes until just set. Remove from oven and let cool slightly.
  • Make Cheesecake Layer:
  • In a large bowl, beat softened cream cheese until smooth. Add sugar, eggs, vanilla, and sour cream. Mix until creamy. Pour over the baked brownie layer.
  • Bake Again:
  • Return to oven and bake for another 30 minutes or until center is slightly jiggly. Turn off oven, crack the door, and let cheesecake cool inside for 1 hour.
  • Chill:
  • Refrigerate for at least 4 hours (or overnight).
  • Prepare Ganache:
  • Heat heavy cream until just simmering. Pour over chocolate chips and let sit 2 minutes, then stir until smooth. Let it cool slightly and pour over chilled cheesecake.
  • Top It Off:
  • Add whipped cream, cherries, nuts, sprinkles, or your favorite sundae toppings right before serving.

Notes

– Can be frozen without toppings for up to 1 month.
– Allow cheesecake to sit at room temp 15 mins before serving for best texture.
– Add extra toppings just before serving for a fresh, sundae-like look.
