Ingredients

Scale

For the crust

  • 2 cups vanilla wafer crumbs (about 60 wafers)
  • 6 tablespoons unsalted butter, melted
  • 2 tablespoons light brown sugar
  • 1/4 teaspoon fine sea salt

For the filling

  • 1 1/2 quarts banana ice cream, slightly softened
  • 2 medium ripe bananas, sliced into thin rounds
  • 1 cup whipped topping, plus extra for garnish if desired
  • 1 teaspoon pure vanilla extract

For the hot fudge topping

  • 3/4 cup semisweet chocolate chips
  • 1/2 cup heavy cream
  • 2 tablespoons unsalted butter
  • 2 tablespoons unsweetened cocoa powder
  • 2 tablespoons light corn syrup
  • 1 teaspoon pure vanilla extract
  • Pinch of salt

Optional garnish

  • 1/4 cup chopped toasted walnuts or pecans
  • Extra banana slices
  • Chocolate curls or shaved chocolate

Instructions

  1. Prepare the crust: In a medium bowl, combine vanilla wafer crumbs, melted butter, brown sugar, and sea salt. Stir until evenly moistened and the mixture resembles wet sand. Press firmly into the bottom of a 9-inch springform pan using the bottom of a measuring cup for an even layer. Freeze for 15 to 20 minutes to firm up.
  2. Soften and mix the filling: Let banana ice cream sit at room temperature for 10 to 15 minutes until spreadable. In a large bowl, fold the softened ice cream with whipped topping and vanilla extract until just combined to lighten the texture and improve sliceability.
  3. Build the layers: Remove crust from freezer. Spread half of the ice cream mixture evenly over crust. Top with a layer of sliced bananas using about 1 medium banana. Spread remaining ice cream mixture on top, smoothing with a spatula. Arrange remaining banana slices over the top if desired. Cover tightly with plastic wrap or foil and freeze for at least 6 hours, preferably overnight.
  4. Make the hot fudge: In a small saucepan over low heat, combine semisweet chocolate chips, heavy cream, butter, cocoa powder, corn syrup, and salt. Stir constantly until smooth and glossy, about 4 to 5 minutes. Remove from heat and stir in vanilla extract. Let cool slightly but keep pourable. Can be made ahead and reheated gently before serving.
  5. Unmold and serve: Remove cake from freezer 5 to 10 minutes before slicing. Release springform pan and transfer cake to serving plate. Garnish with extra whipped topping, chopped nuts, banana slices, or shaved chocolate as desired. Slice with a sharp knife dipped in warm water and wiped dry between cuts for neat slices. Spoon warm hot fudge over each slice just before serving.

Notes

  • Use banana ice cream with strong banana flavor for best results; fresh banana slices enhance the flavor further.
  • Let ice cream soften just enough to spread but avoid melting it to prevent icy layers.
  • Press and freeze the crust before adding the filling to keep layers distinct.
  • Use ripe but firm bananas to avoid mushy texture and browning inside the cake.
  • Dip knife in warm water and dry between slices for clean cuts.
  • Add decorative banana slices just before serving to prevent browning.
  • Store cake tightly wrapped in freezer up to 1 week; store hot fudge refrigerated up to 5 days, reheat gently.
  • Variations include adding chopped nuts between layers or substituting chocolate cookie crust for vanilla wafers.
