Preparing Banana Walnut Cake
Baking a delicious banana walnut cake is not just about the end result; it’s also about enjoying the process! Let’s walk through the steps together, ensuring you have everything prepared and ready to create this delightful treat.
Gather and Prepare Your Ingredients
Before you dive into baking, it’s crucial to gather all your ingredients. Here’s what you’ll need:
- Butter: Softened for easy mixing.
- Bananas: The riper, the better! Aim for about 5 cups of sliced bananas (about 8-10 bananas).
- Sugars: Both granulated and brown sugar add depth to the flavor.
- Flour: All-purpose flour will be your base.
- Baking Essentials: Baking powder, baking soda, and sea salt for leavening.
- Eggs: Keep them at room temperature for better emulsification.
- Buttermilk: Adds moisture and a subtle tang.
- Walnuts: Chopped, for that delightful crunch.
- White Chocolate: Shaved for a finishing touch.
Make sure to preheat the oven to 350°F and grease and flour your 8-inch cake pans for easy removal later.
Make the Caramelized Banana Mixture
This step is the magic of the banana walnut cake! In a skillet over medium-high heat, combine ¼ cup of butter and 2 tablespoons of brown sugar. Add in 2 cups of sliced bananas and cook until they’re caramelized—around 5 to 7 minutes. This will enhance their flavor beautifully. Once caramelized, transfer them to a bowl and mash them with a fork. It’s okay if there are still some small chunks; they add to the texture!
Prepare the Dry Ingredients
In a large bowl, whisk together 3 cups of all-purpose flour, 1 teaspoon each of baking powder, baking soda, and sea salt. Ensuring these are well-mixed will help with the cake's rise and texture.
Cream the Butter and Sugars
With a stand mixer fitted with a paddle attachment, beat the remaining ¾ cup of butter at high speed until it’s creamy—about a minute. Then add the granulated and brown sugars, mixing until they’re fully combined. This should take around 2 minutes. It’s the perfect time to add in your eggs and vanilla extract, and lastly, mix in those mashed caramelized bananas.
Mix in Eggs and Bananas
After combining, you’ll want to switch to low speed and gradually add in your dry ingredients and buttermilk—aim for a gentle mix to avoid overworking the batter. If you’re using walnuts, gently fold in ¾ cup at this stage for that delightful crunch in every bite!
Combine Dry Ingredients with Buttermilk
Pour your batter evenly between the prepared cake pans. Bake for 40 to 45 minutes. Keep an eye on them—once a toothpick inserted in the center comes out clean, they’re ready to cool!
Bake the Cake Layers
Once baked, allow the cakes to cool completely in the pans on a wire rack before attempting to frost them. Trust me, if you rush this step, you'll end up with a melty frosting disaster.
Prepare the Whipped Cream Frosting
A luscious whipped cream frosting will top off your banana walnut cake beautifully. Beat together chilled heavy cream, sugar, and vanilla on high until stiff peaks form. This will take just a few minutes.
Assemble the Cake
Time for the fun part! Level the tops of your cooled cakes and slice each in half horizontally, so you have four layers. On your serving plate, start by placing one layer down and spreading a layer of whipped cream on top, followed by sliced bananas. Repeat this process with the remaining layers, finishing with whipped cream on top. For a professional touch, sprinkle with chopped walnuts and white chocolate shavings.
Now step back, admire your creation, and invite some friends over to enjoy this marvelous banana walnut cake together! Your amazing effort will surely be a hit.

Variations on Banana Walnut Cake
Adding Chocolate Chips
If you’re a chocolate lover, consider tossing in some semi-sweet or dark chocolate chips to your banana walnut cake batter. The rich flavor of chocolate complements the sweet bananas beautifully, creating a delightful contrast. Just fold in about a cup of chocolate chips right before pouring the batter into your prepared pans. This addition not only enhances the taste but also provides a pleasing texture.
Experimenting with Different Nuts
While walnuts are a classic choice, don’t be afraid to experiment with different nuts! Pecans, almonds, or hazelnuts can offer unique flavors and textures. Just remember to chop them roughly and add about a cup to your batter. Each nut will bring a distinct twist to your banana walnut cake, making it feel fresh and innovative, perfect for impressing guests or treating yourself! For more tips, check out King Arthur Baking.
Baking Notes for Banana Walnut Cake
Tips for Ensuring a Moist Cake
To guarantee your banana walnut cake turns out moist and delicious, follow these helpful tips:
-
Use Overripe Bananas: The riper your bananas, the sweeter and more flavorful your cake will be. Dark brown spots are a sign they're perfect!
-
Don’t Overmix: Gently mix your batter. Overmixing can create a dense texture, while gentle folding helps maintain that airy consistency.
-
Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature to emulsify better, producing a moist crumb.
-
Bake Right: Keep an eye on your cake while it bakes. Overbaking can dry it out; a toothpick should come out with a few moist crumbs, not completely clean.

FAQs about Banana Walnut Cake
Can I use frozen bananas for the cake?
Absolutely! Frozen bananas work wonderfully in banana walnut cake. In fact, many bakers prefer using them because they're often sweeter and easier to mash. Just make sure to thaw them completely and drain any excess liquid before incorporating them into your batter for the best results.
How do I store leftover cake?
Storing your leftover banana walnut cake is simple! Keep it in an airtight container at room temperature for up to two days. If you want to enjoy it longer, pop it in the fridge, where it can last about a week. For even more extended storage, consider freezing individual slices wrapped in plastic wrap and then placed in a freezer bag. Just thaw before serving!
What can I substitute for buttermilk?
If you don’t have buttermilk on hand, don’t fret! You can easily make a substitute by mixing 1 cup of milk with 1 tablespoon of lemon juice or white vinegar. Stir and let it sit for about 5 minutes until it thickens slightly. This will give you that tangy flavor and acidity that buttermilk adds to the cake. For more ideas on substitutes, check out this guide on buttermilk alternatives.

Instructions
Preparation
- Preheat the oven to 350°F with a rack in the center position. Grease and flour two 8-inch cake pans.
- Heat a large skillet over medium-high heat. Add ¼ cup of the butter, 2 tablespoons of the brown sugar, and 2 cups of the bananas and cook until the bananas are caramelized, 5 to 7 minutes. Transfer the bananas to a medium bowl and mash with a fork.
- In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
- In a stand mixer fitted with a paddle attachment, beat the remaining ¾ cup of butter on high speed until smooth and creamy, about 1 minute. Add the sugar and the remaining ½ cup of brown sugar and beat on high for about 2 minutes, or until creamed together. Add the eggs and the vanilla and beat until combined. Add the mashed caramelized bananas and beat until combined.
- With the mixer on low speed, alternate adding ⅓ of the flour mixture and ⅓ of the buttermilk, being careful not to over mix. Stir in ¾ cup of the walnuts, if using.
- Pour the batter into the prepared cake pans, dividing evenly. Bake for 40 to 45 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow the cakes to cool completely in the pans set on a wire rack.
- Make the whipped cream. Using a handheld or stand mixer fitted with a whisk attachment, beat the cream, sugar, and vanilla on high speed until stiff peaks form.
- Using a large serrated knife, slice off the tops of the cakes to create a flat surface. Carefully slice each cake in half (horizontally), creating 4 separate (equally thick) layers. Place 1 cake layer on your cake stand, or serving plate.
- Add about ⅕ of the whipped cream to the top of the cake and spread into an even layer. Top with an even layer of the remaining banana slices. Top with the second cake layer, cut side down. Repeat with remaining whipped cream, banana slices and cake layers. Spread the remaining whipped cream over the top and sides of the cake in an even layer. Decorate with remaining walnuts and white chocolate.
