Ingredients:
- 1/2 cup (113g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- 1/2 cup (42g) unsweetened cocoa powder
- 1/4 teaspoon salt
- 1 teaspoon vanilla extract
- 2 large eggs
- 1/2 cup (60g) all-purpose flour
- 1.5 quarts (approx. 1.4 liters) high-quality vanilla ice cream, slightly softened
- 1.5 cups (about 18 standard-sized) Oreo cookies, coarsely crushed
- 1 cup (about 12 standard-sized) Oreo cookies, finely crushed
- 2 tablespoons (28g) unsalted butter, melted
- 1 cup (240ml) heavy cream
- 8 ounces (227g) semi-sweet chocolate, finely chopped
Instructions:
- Preheat oven to 350°F (175°C). Line the bottom of a 9-inch springform pan with parchment paper.
- In a large bowl, combine melted butter, sugar, cocoa powder, and salt.
- Stir in vanilla extract. Beat in eggs one at a time.
- Gradually add flour, mixing until just combined.
- Pour batter into the prepared pan and spread evenly.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with moist crumbs. Let cool completely in the pan.
- Combine crushed Oreo cookies and melted butter in a bowl.
- Press firmly onto the cooled brownie base. Freeze for 30 minutes to firm up.
- Let ice cream soften slightly at room temperature (but don't let it melt completely!).
- In a large bowl, gently fold together the softened ice cream and coarsely crushed Oreo cookies.
- Spread the ice cream mixture evenly over the Oreo crumb layer.
- Freeze for at least 2 hours, or until solid.
- Heat heavy cream in a saucepan over medium heat until simmering. Do not boil.
- Pour hot cream over chopped chocolate in a bowl.
- Let sit for 1 minute, then whisk until smooth and glossy.
- Remove the cake from the freezer and carefully release it from the springform pan.
- Pour the slightly cooled chocolate ganache over the top of the ice cream layer, spreading evenly with an offset spatula.
- Freeze for at least 2 more hours, or until the ganache is firm.
- Let the ice cream cake sit at room temperature for 5-10 minutes before slicing and serving.
