Ingredients:

  • 25 Oreo cookies (about 265g), finely crushed
  • 6 tablespoons (85g) unsalted butter, melted
  • 1 cup (227g) unsalted butter, melted
  • 2 cups (400g) granulated sugar
  • 1 cup (85g) unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 4 large eggs
  • 1 cup (125g) all-purpose flour
  • 1 cup (170g) semi-sweet chocolate chips
  • 1.5 quarts high-quality vanilla bean ice cream, softened
  • 1 cup (240ml) hot fudge sauce, store-bought or homemade, cooled slightly
  • Whipped cream, chocolate shavings, extra Oreo cookie crumbs, maraschino cherries (optional)

Instructions:

  1. Combine crushed Oreo cookies and melted butter. Press firmly into the bottom of the springform pan. Freeze for 15 minutes.
  2. Whisk together melted butter, sugar, cocoa powder, salt, and vanilla extract. Add eggs one at a time, mixing well after each addition. Gradually add flour and mix until just combined. Fold in chocolate chips.
  3. Pour brownie batter over the prepared Oreo crust. Bake at 350°F (175°C) for 30-35 minutes, or until a toothpick inserted into the center comes out with fudgy crumbs.
  4. Let the brownies cool completely in the pan. This is crucial to avoid melting the ice cream later.
  5. Allow ice cream to soften slightly at room temperature until spreadable, but not completely melted.
  6. Spread half of the softened ice cream evenly over the cooled brownie layer. Drizzle with half of the hot fudge sauce.
  7. Spread the remaining ice cream over the hot fudge, then drizzle with the remaining hot fudge sauce.
  8. Cover the springform pan with plastic wrap and freeze for at least 4 hours, preferably overnight, until completely frozen solid.
  9. Run a warm knife around the edge of the pan to loosen the cake. Release the springform pan and carefully remove the cake.
  10. Decorate with whipped cream, chocolate shavings, Oreo cookie crumbs, and/or maraschino cherries.
  11. Cut into slices and serve immediately. If the cake is very hard, let it sit at room temperature for a few minutes before slicing.
