Ingredients

  • 1 box brownie mix (18.3 oz)
  • 2 large eggs (or as directed on box)
  • ½ cup vegetable oil (or as directed on box)
  • ¼ cup water (or as directed on box)
  • 1 ½ cups crushed vanilla wafer cookies (about 45)
  • 6 Tbsp powdered sugar
  • 6 Tbsp unsweetened cocoa powder
  • ½ cup unsalted butter, melted
  • 32 oz cream cheese (4 packages, softened)
  • 1 cup granulated sugar
  • 4 large eggs
  • 1 tsp vanilla extract
  • ½ cup hot fudge sauce (slightly warmed)

Instructions

  1. Prepare brownies according to package with eggs, oil, and water. Bake in 9×9-inch pan, cool, and cut into ¾-inch cubes.
  2. Preheat oven to 350°F (175°C). Mix crushed vanilla wafers, powdered sugar, cocoa, and melted butter until sandy. Press into bottom of 9-inch springform pan. Bake 8 minutes, then cool.
  3. Beat cream cheese until smooth. Add sugar, mix, then add eggs one at a time. Stir in vanilla.
  4. Fold half the brownie cubes into cheesecake batter. Pour over cooled crust and smooth top.
  5. Drizzle warmed hot fudge over batter in swirls. Use knife or skewer to create a marbled effect.
  6. Bake 50–55 minutes until mostly set but slightly jiggly in center. Turn off oven, crack door, and cool inside 1 hour.
  7. Cool to room temp, then refrigerate at least 4 hours or overnight.
  8. Remove from springform pan and garnish with extra brownie chunks, fudge, whipped cream, or cherries if desired.

Notes

  • Swap vanilla wafers for Oreos or graham crackers for a crust variation.
  • Add nuts to the brownies for extra crunch.
  • Try caramel or berry preserves instead of fudge for a twist.
  • Chill overnight for best texture and clean slicing.
  • Use full-fat brick-style cream cheese for structure and richness.
