Ingredients You’ll Need
The magic of this cake lies in its simple but thoughtfully chosen ingredients that combine to create such an unforgettable taste and texture. Each one has a role, whether it’s adding moisture, that special nutty crunch, or the creamy finish that brings it all together.
- 2 cups all-purpose flour: The base of the cake providing structure and tenderness.

- 2 large eggs: Bind the ingredients together and contribute to the cake’s fluffiness.

- 1/2 cup sour cream: Keeps the cake moist and tender with a slight tang.
- 3 ripe bananas, mashed: Provide natural sweetness, moisture, and that signature banana flavor.
- 1/2 cup chopped walnuts: Adds a lovely crunch and nutty depth throughout the cake.
- 1/2 cup white chocolate chips: Offer little pockets of creamy sweetness that melt in your mouth.
- 2 cups creamy custard: The luscious filling and topping that makes this truly a cream cake.

How to Make Heavenly Banana Walnut Cream Cake Recipe
Step 1: Prep Your Ingredients and Oven
Start by preheating your oven to 350°F (175°C) so it’s ready to go once your batter is mixed. Grease and flour your baking pan to ensure that flawless release. Also, mash your ripe bananas until smooth—ripe bananas are key for maximum flavor and moisture in the cake.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. This dry mix will give your cake its structure and rise. Setting this aside keeps your process organized and ensures even distribution of rising agents.
Step 3: Combine Butter and Sugar
In a large mixing bowl, cream the softened butter and granulated sugar until light and fluffy. This step is crucial—it creates air pockets that help your cake become light and tender. Take your time for the best texture.
Step 4: Add Eggs and Vanilla
Beat in the eggs one at a time, then stir in the vanilla extract. Eggs build the cake’s framework, and vanilla adds that lovely warm aroma we all crave in a good dessert.
Step 5: Incorporate Sour Cream and Bananas
Mix the sour cream and mashed bananas into the wet ingredients. The sour cream keeps the cake moist and tender, while the bananas infuse it with their sweet, distinctive flavor. This combination makes the cake irresistibly soft.
Step 6: Fold in Dry Ingredients, Walnuts, and White Chocolate Chips
Gently fold the flour mixture into the wet ingredients just until combined—overmixing can make the cake dense. Then fold in the chopped walnuts and white chocolate chips, making sure they are evenly distributed throughout the batter for perfect texture contrasts in every bite.
Step 7: Bake the Cake
Pour the batter into your prepared pan and smooth the top. Bake for about 55 minutes or until a toothpick inserted in the center comes out clean. The kitchen will fill with an irresistible aroma, and you’ll know the cake is nearly ready.
Step 8: Cool and Assemble with Custard
Once baked, let the cake cool completely on a wire rack. When cool, slice the cake horizontally to create layers, and spread the creamy custard generously between each layer and on top. This luscious custard is what truly elevates this recipe to the status of Heavenly Banana Walnut Cream Cake Recipe.
How to Serve Heavenly Banana Walnut Cream Cake Recipe

Garnishes
Finish your cake with beautifully sliced bananas and sprinkle whole or halved walnuts on top. This not only elevates the visual appeal but adds freshness and crunch to each indulgent bite. The garnishes make the cake look stunning and invite everyone to dig in.
Side Dishes
This cake shines all on its own, but you could serve it alongside a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence. A cup of hot coffee or tea also complements the sweet and nutty flavors perfectly.
Creative Ways to Present
If you want to get fancy, slice the cake into smaller squares and serve on pretty dessert plates, each topped with a drizzle of caramel sauce or a sprinkle of cinnamon. For parties, individual glass trifle cups layered with extra custard and banana slices can make for an eye-catching presentation that guests will love.
Make Ahead and Storage
Storing Leftovers
Store any leftover cake in an airtight container in the refrigerator for up to 3 days. Keep the custard-filled cake chilled to maintain that creamy texture and freshness, and avoid drying out the banana layers.
Freezing
You can freeze slices of this cake if wrapped tightly in plastic wrap and aluminum foil. Freeze for up to 2 months for best quality. Thaw overnight in the fridge before serving, and the cake will still be moist and delightful.
Reheating
This cake is best enjoyed cold or at room temperature due to the custard filling, but if you prefer a warm bite, let a slice sit at room temperature for about 20 minutes before eating. Avoid microwaving as the custard might separate or become too runny.
FAQs
Can I use walnuts substitutes in the Heavenly Banana Walnut Cream Cake Recipe?
Absolutely! Pecans or almonds can be wonderful substitutes if you want a different nutty twist. Just keep the quantity the same to maintain texture and flavor balance.
How ripe should my bananas be for this recipe?
Very ripe bananas with brown spots are ideal because they’re sweeter and mash easily, ensuring your cake is moist and full of banana flavor.
Can I make this cake gluten-free?
