  • Eggs, oil, and water as specified on the brownie mix package
  • ½ teaspoon espresso powder (optional, for intensified chocolate flavor)

Cheesecake Filling

  • 24 ounces cream cheese, softened
  • 1 cup granulated sugar
  • 3 large eggs, at room temperature
  • 1 cup sour cream
  • 1 teaspoon vanilla extract
  • 2 tablespoons all-purpose flour

Hot Fudge Topping

  • ½ cup semisweet chocolate chips (optional, for extra richness)

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Gather all your ingredients.
  • Line a 9-inch springform pan with parchment paper, lightly greasing the sides.

Cook the Base

  • Mix the brownie batter according to the package directions, adding espresso powder if desired.
  • Spread the batter evenly in the prepared pan and bake for about 20 to 25 minutes.

Cool the Brownie Base

  • Allow the brownie to cool slightly while you prepare the cheesecake filling.

Make the Cheesecake Filling

  • Beat the softened cream cheese until smooth and fluffy, then add sugar and mix.
  • Add eggs one at a time, mixing well after each.
  • Blend in sour cream, vanilla extract, and flour until combined.
  • Pour the cheesecake filling over the slightly cooled brownie base.

Bake the Cheesecake

  • Reduce oven temperature to 325°F (160°C). Place the pan in a larger roasting pan and add hot water around the sides.
  • Bake for 55 to 65 minutes, or until edges are firm but center is slightly jiggly.

Cooling

  • Turn off the oven and crack the door open. Let the cheesecake rest inside for about an hour.
  • Cool completely at room temperature, then refrigerate for a minimum of 4 to 6 hours or overnight.

Add Toppings

  • Warm the hot fudge sauce until pourable and spread it over the chilled cheesecake layer.
  • Chill for an additional 20 minutes. Garnish with whipped cream, sprinkles, nuts, cherries, and more hot fudge sauce before serving.

Notes

Store leftovers in an airtight container for up to 5 days. For best flavor, serve with vanilla ice cream or fresh fruits.
