Ingredients
  

Brownie Base

  • 1 box brownie mix (18 oz)
  • Ingredients listed on box (eggs, oil, water)
  • ½ tsp espresso powder (optional) Enhances flavor

Cheesecake Filling

  • 24 oz cream cheese, softened
  • 1 cup sugar
  • 3 large eggs, room temperature
  • 1 cup sour cream
  • 1 tsp vanilla extract
  • 2 tbsp all-purpose flour

Hot Fudge Layer

  • 1 cup hot fudge sauce
  • ½ cup chocolate chips (optional)

Sundae Garnish

  • Whipped cream
  • Sprinkles
  • Chopped nuts
  • Maraschino cherries
  • Extra hot fudge for drizzling

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C). Line and grease a 9-inch springform pan.
  • Prepare the brownie batter according to the package instructions, adding the optional espresso powder if using.
  • Pour the batter into the pan and bake for 20–25 minutes, until the brownie is set but still slightly underdone. Let it cool slightly.

Make the Cheesecake Filling

  • In a large bowl, beat the cream cheese until smooth and fluffy. Add the sugar and mix well.
  • Add the eggs one by one, mixing after each addition. Then mix in the sour cream, vanilla extract, and flour.
  • Beat until everything is smooth and creamy. Pour the cheesecake batter gently over the brownie base and smooth the top.

Bake the Cheesecake

  • Lower the oven temperature to 325°F (160°C). Place the springform pan in a water bath and bake for 55–65 minutes, until the edges are set and the center still slightly jiggles.
  • Turn off the oven, crack the door slightly, and let the cheesecake cool slowly inside. Then refrigerate for 4–6 hours until completely set.

Add the Hot Fudge Layer

  • Warm the hot fudge sauce slightly so it spreads easily. Spread it evenly over the chilled cheesecake.
  • Sprinkle the chocolate chips on top if using. Refrigerate for 20 minutes to let the layer set.

Garnish Like a Sundae

  • Before serving, decorate the cheesecake with whipped cream, sprinkles, chopped nuts, cherries, and an extra drizzle of hot fudge.

Notes

Chill the cheesecake overnight for the creamiest texture and cleanest slices. Always use a warm knife (wipe between cuts) for perfect slices. Use good-quality hot fudge sauce for the best flavor and glossy finish. Don’t overbake; the center should still jiggle slightly when you turn off the oven.
