This rich and indulgent layered cake features a soft sponge base and two creamy fillings—one with chocolate and another with chopped banana—topped with fluffy whipped cream.
Ingredients
For the Sponge Base:
- 15 large egg whites
- 15 tablespoons granulated sugar (approx. 1 cup)
- 15 tablespoons all-purpose flour (about 1 cup)
- 2 tablespoons vegetable oil
Filling I:
- 2 cups milk
- 15 tablespoons granulated sugar (just under 1 cup)
- 15 large egg yolks
- 15 tablespoons all-purpose flour (about 1 cup)
- 2 packets vanilla pudding mix (cook type)
Filling II:
- 1 cup unsalted butter, softened
- 3 1/2 cups powdered sugar
- 15 chopped cream bananas (about 2 cups)
- 7 oz semisweet chocolate, melted
- 1 1/2 cups whipped topping or whipping cream (prepared)
For Topping:
- Additional whipped topping or whipped cream
- Optional decorations like chocolate shavings or banana slices
Instructions
Preheat the oven to 350°F and grease a 9×13-inch rectangular baking pan or line it with parchment paper. Beat the egg whites until stiff peaks form, gradually adding sugar. Gently fold in the flour and oil until fully combined. Pour the batter into the prepared pan and bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely before proceeding.
Whisk together the egg yolks, sugar, and flour until smooth. Heat the milk in a saucepan until hot but not boiling, then slowly whisk it into the yolk mixture. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until thickened. Separately, prepare the vanilla pudding according to the package instructions, then mix it with the cooled custard.
In a large bowl, beat the butter and powdered sugar until creamy. Divide the custard mixture in half. Mix the melted chocolate into one half and fold the chopped bananas into the other half.
Place the cooled sponge base on a serving platter. Spread the chocolate filling evenly over the base. Layer the banana filling on top of the chocolate filling. Cover the entire cake with whipped topping, smoothing it out evenly.
Decorate as desired with whipped cream, chocolate shavings, or banana slices. Chill the cake for at least 2 hours before serving.
