Heavenly Banana Walnut Cream Cake Recipe
Introduction
This Heavenly Banana Walnut Cream Cake combines moist banana-infused layers with crunchy walnuts and creamy custard filling. It’s a perfect dessert for banana lovers craving a rich, textured treat.

Ingredients
- 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
- 2 cups creamy custard (store-bought or homemade)
- 1 banana, sliced (for garnish)
- 1/4 cup whole or halved walnuts (for garnish)
Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans to ensure the cakes bake evenly and don’t stick.
- Step 2: In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
- Step 3: Using a mixer, cream the softened butter and sugar on medium speed until light and fluffy, about 2-3 minutes.
- Step 4: Beat in the eggs one at a time, fully incorporating each before adding the next. Stir in the vanilla extract.
- Step 5: Mix in sour cream and mashed bananas until the batter is smooth and well combined.
- Step 6: Gradually add the dry ingredients to the wet mixture, stirring just until combined. Avoid overmixing.
- Step 7: Gently fold in the chopped walnuts and white chocolate chips for added texture and flavor.
- Step 8: Divide the batter evenly between the prepared pans. Bake for 30-35 minutes or until a toothpick inserted comes out clean. Cool in pans for 10 minutes, then transfer to wire racks to cool completely.
- Step 9: Place one cake layer on a serving plate and spread half the custard over it. Top with the second layer and spread the remaining custard on top.
- Step 10: Garnish with banana slices and walnuts. Serve immediately or refrigerate until ready to enjoy.
Tips & Variations
- Use very ripe bananas for the sweetest and moistest cake.
- Swap the white chocolate chips for dark chocolate chips for a richer flavor contrast.
- Make your own custard for a fresher taste or use a high-quality store-bought custard to save time.
- For extra softness, substitute half the all-purpose flour with cake flour.
Storage
Store the cake covered in the refrigerator for up to 3 days to keep the custard fresh. Bring to room temperature before serving for the best texture. You can also freeze the un-frosted cake layers wrapped tightly for up to 1 month and add custard after thawing.

FAQs
Can I make this cake gluten-free?
Yes, substitute the all-purpose flour with a gluten-free baking blend that can be used cup-for-cup. Make sure the baking blend contains xanthan gum for structure.
What can I use instead of walnuts?
You can substitute walnuts with pecans or almonds, or leave them out altogether if you prefer a nut-free version. Toasting the nuts beforehand enhances their flavor.

Ingredients
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

- 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
- 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.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside for later.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
