12 to 16 servings

  • Cake:
  • Cooking spray, for coating aluminum foil
  • 1 box chocolate cake mix for two 9-inch rounds (or your favorite flavor)
  • 1/3 cup vegetable oil
  • 1 large egg
  • 5 cups chocolate ice cream, softened
  • 1 1/2 cups cold heavy cream
  • 1 tablespoon sugar
  • Chocolate Sauce:
  • 4 ounces semisweet chocolate, broken into large chunks
  • 3/4 cup heavy cream
  • 1/4 cup corn syrup
  • 3 tablespoons unsalted butter
  • 1/8 teaspoon kosher salt
  • Suggested toppings: chocolate sprinkles, chocolate chips, crushed chocolate wafer cookies, maraschino cherries and chocolate-covered raisins, nuts and pretzels
  • For the cake: Position an oven rack in the middle of the oven and preheat to 350 degrees F. Line a 9-by-13-inch cake pan with aluminum foil and coat it with cooking spray.

  • Beat the cake mix, oil, egg and 1/4 cup water in a large bowl with an electric mixer on medium speed until smooth. Let stand a few minutes until no longer tacky, and then pat into the prepared pan.

  • Bake until the edges are set, the cake has deflated and the top is no longer wet and shiny, 20 to 25 minutes. Let cool completely, about 1 hour.

  • Spread the softened ice cream over the cake in an even layer. Cover with plastic wrap and freeze until firm, at least 4 hours or overnight.

  • For the chocolate sauce: Combine the chocolate, cream, corn syrup, butter and salt in a medium saucepan over medium heat. Whisk periodically as the mixture comes to a gentle simmer. Simmer for 5 minutes, stirring occasionally. If the sauce starts to boil, turn down the heat. Cool 15 minutes before serving. Transfer to a bowl or small pitcher.

  • Let the cake stand at room temperature for about 20 minutes before serving.

  • Whip the cream with the sugar in a chilled medium bowl with an electric mixer until stiff peaks form. Spread the whipped cream over the ice cream layer to cover.

  • Use the foil to lift the cake out of the pan and place on a serving platter. Slice and serve along with the chocolate sauce and your favorite toppings, such as chocolate sprinkles, chocolate chips, crushed chocolate wafer cookies, maraschino cherries and chocolate-covered raisins, nuts and pretzels.
