Ingredients

  • 1 standard box of brownie mix
  • ½ cup vegetable oil
  • 3 tablespoons water
  • 4 large eggs, divided (room temperature)
  • 16 oz cream cheese, softened (2 × 8 oz packages)
  • ⅔ cup granulated sugar
  • 1 tablespoon all-purpose flour
  • 1 teaspoon vanilla extract
  • ¼ cup sour cream, room temperature
  • 1¼ cups heavy whipping cream, divided
  • 3 tablespoons powdered sugar
  • ½ cup hot fudge sauce or chocolate ganache (for serving)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
  2. In a bowl, mix brownie mix, vegetable oil, water, and 2 eggs. Pour batter into prepared pan and bake for 15 minutes until just set on top.
  3. While brownie is baking, prepare cheesecake filling: beat softened cream cheese until smooth. Add granulated sugar and mix until combined.
  4. Add flour, vanilla extract, sour cream, and ¼ cup heavy cream. Mix until smooth.
  5. Stir in remaining 2 eggs one at a time by hand (not with a mixer).
  6. Pour cheesecake batter over hot brownie layer.
  7. Reduce oven to 325°F (160°C) and bake for 45 minutes. Then turn off oven and keep door closed for 20 minutes.
  8. Crack oven door and allow cheesecake to cool inside for another 30 minutes.
  9. Remove cheesecake and let it come to room temperature. Then refrigerate for 2–3 hours or until fully set.
  10. Before serving, whip 1 cup heavy cream with powdered sugar until stiff peaks form. Spread or pipe on top of cheesecake.
  11. Drizzle with hot fudge or chocolate ganache and serve chilled.

Notes

  • Use a homemade brownie batter if preferred; adjust bake time accordingly.
  • Mix chocolate chunks or chopped nuts into brownie layer for texture.
  • Top with fresh berries or berry sauce instead of fudge for a fruity twist.
  • Chilling is essential for clean slicing and the best texture.
  • Freeze undecorated cheesecake for up to 1 month; thaw before serving.
