Ingredients

Scale

For the Cake:

  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup sour cream
  • 3 ripe bananas, mashed
  • 1/2 cup chopped walnuts
  • 1/2 cup white chocolate chips

For the Filling and Topping:

  • 2 cups creamy custard (store-bought or homemade)
  • 1 banana, sliced (for garnish)
  • 1/4 cup whole or halved walnuts (for garnish)

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans to ensure the cakes don’t stick and bake evenly.
  2. Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside for later.
  3. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar using a hand mixer or stand mixer. Beat on medium speed until the mixture becomes light and fluffy, about 2-3 minutes.
  4. Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract for added flavor.
  5. Add Sour Cream and Bananas: Mix in the sour cream and mashed bananas until the batter is smooth and well combined. The bananas add natural sweetness and moisture, while the sour cream adds richness.
  6. Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can result in a denser cake.
  7. Fold in Walnuts and White Chocolate Chips: Gently fold in the chopped walnuts and white chocolate chips. These ingredients add texture and a delicious contrast to the soft cake.
  8. Bake the Cake: Divide the batter evenly between the two prepared cake pans. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Once done, let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.
  9. Assemble the Cake: Once the cakes have cooled, place one layer on a serving plate and spread half of the creamy custard over the top. Carefully place the second layer on top and spread the remaining custard over the top of the cake.
  10. Garnish and Serve: Garnish the cake with fresh banana slices and whole or halved walnuts for a beautiful presentation. Serve immediately or refrigerate until you’re ready to serve.

Notes

  • Make sure bananas are very ripe for best flavor and sweetness.
  • Do not overmix the batter after adding the dry ingredients to keep the cake light and fluffy.
  • You can substitute the custard with whipped cream or cream cheese frosting if preferred.
  • Store the cake refrigerated if not serving immediately to keep the custard fresh.
  • Allow the cake layers to cool completely before assembling to prevent custard from melting.
