Ingredients You’ll Need
Get ready to gather a handful of simple, classic baking staples—each chosen with care for their unique flavors and textures. Every element plays a key role in making this Luscious Vanilla Banana Walnut Cake as moist, flavorful, and tempting as it is beautiful.
- All-purpose flour: The foundation for a soft, tender crumb that holds everything together.
- Baking soda: Gives the cake its signature rise and keeps it fluffy.
- Salt: Just a pinch pulls all the flavors into focus and balances the sweetness.
- Cinnamon (optional): Adds a gentle layer of cozy warmth behind the fruitiness.
- Unsalted butter, softened: Creams up beautifully for a rich, melt-in-your-mouth texture.
- Granulated sugar (or a mix of white and brown): Sweetens the cake and lends moisture—try half brown sugar for a hint of caramel depth.
- Large eggs: Help bind the batter and add structure and richness.
- Vanilla extract: The aromatic centerpiece that enhances the banana flavor and adds luscious aroma.
- Sour cream or plain yogurt: Makes the cake extra moist and tender, never dry.
- Ripe bananas, mashed: The star ingredient—go for very ripe bananas for natural sweetness and a deeply banana-rich flavor.
- Chopped walnuts (plus extra for garnish): Bring irresistible crunch and nutty flavor both inside and on top.
- Creamy custard or cream cheese frosting: The decadent finishing touch, smoothing and sweetening every slice.
- Banana slices (for garnish): Add fresh fruit flavor and make every serving look gorgeous.
How to Make Luscious Vanilla Banana Walnut Cake
Step 1: Prep Your Pan and Oven
Preheat your oven to 350°F (175°C). Line or grease an 8–9 inch cake pan—the right pan makes all the difference for easy release and even baking. I love using parchment at the bottom for extra insurance.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, salt, and cinnamon (if using). This helps to evenly disperse the leavening and spices through the cake for a perfect bite every time.
Step 3: Cream the Butter and Sugar
Add the softened butter and sugar to a large mixing bowl and cream them together until light and fluffy, about 2-3 minutes. This step is crucial for a Luscious Vanilla Banana Walnut Cake with that dreamy, airy crumb—don’t rush it!
Step 4: Add the Eggs and Vanilla
Beat in the eggs one at a time into the butter mixture, scraping down the sides as needed. Add the pure vanilla extract for its warm, mellow aroma that makes the banana flavor pop.
Step 5: Mix in the Bananas and Sour Cream
Gently fold in the mashed bananas and the sour cream (or plain yogurt). This duo keeps the crumb immensely moist and infuses the cake with natural sweetness.
Step 6: Combine Wet and Dry Ingredients
Fold the dry ingredients into the wet mixture, taking care not to overmix. Once you see the last streak of flour disappear, stop! This keeps your Luscious Vanilla Banana Walnut Cake soft and tender instead of dense.
Step 7: Add the Walnuts
Gently stir in the chopped walnuts. Their crunch brings the perfect contrast to the cake’s soft interior, adding delightful texture to every slice.
Step 8: Bake and Cool
Pour your batter into the prepared pan and smooth the top. Bake for 35–45 minutes, or until a toothpick in the center comes out clean. Let the cake cool completely—otherwise, the frosting will melt right off.
Step 9: Frost and Garnish
Spread a generous layer of creamy custard or cream cheese frosting over the cooled cake. Top with extra walnuts and fresh banana slices for that gourmet finish. Chill briefly for the topping to set before slicing and serving your Luscious Vanilla Banana Walnut Cake.
How to Serve Luscious Vanilla Banana Walnut Cake
Garnishes
The finishing touches make this cake irresistible. Sprinkle a handful of toasted walnuts and arrange banana slices artfully over the frosting. A delicate dust of cinnamon or a drizzle of honey can transform the presentation and add an elegant touch to your Luscious Vanilla Banana Walnut Cake.
Side Dishes
For an afternoon treat, pair a slice with a steaming mug of coffee or a glass of cold milk. If serving as dessert, a scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream turns the Luscious Vanilla Banana Walnut Cake into a fabulous end to any meal.
Creative Ways to Present
Try serving individual squares on colorful dessert plates with a mint sprig. For parties, make it into cupcakes or trifle-style parfaits layered with custard and extra banana slices. However you serve it, this cake always steals the spotlight!
Make Ahead and Storage
Storing Leftovers
Once the cake is frosted and garnished, cover any leftovers with plastic wrap or keep in an airtight container in the refrigerator. The cake stays fresh and moist for up to three days—if it lasts that long!
Freezing
If you want to enjoy a slice of Luscious Vanilla Banana Walnut Cake on demand, freeze unfrosted slices tightly wrapped in plastic and foil. Thaw in the fridge overnight, then frost and garnish just before serving for best texture and flavor.
Reheating
Bring chilled cake to room temperature before serving so the frosting becomes creamy and the crumb softens. If you prefer a slightly warm cake (without frosting), pop a slice in the microwave for 10–15 seconds for a just-baked sensation.
FAQs
Can I use a different type of nut in the cake?
Absolutely! Pecans or hazelnuts are wonderful swaps for walnuts, each adding their own unique crunch and flavor. Just keep the amounts the same for best results.
What’s the best way to ripen bananas quickly?
If your bananas aren’t quite ripe, place them in a paper bag at room temperature for a day or two. For a faster fix, bake unpeeled bananas at 300°F (150°C) for 10-15 minutes until the skins blacken—let them cool before using!
Can I make this cake gluten-free?
Yes—a gluten-free all-purpose flour blend designed for baking can be used in place of regular flour. Just make sure your blend includes xanthan gum or an equivalent stabilizer for the best texture.
What if I don’t have sour cream or yogurt?
You can substitute buttermilk (use a little less—about 1/3 cup) or even plain kefir. The goal is to add moisture and a slight tang to balance the sweetness of the bananas and frosting.
Is this cake better served the day it’s made or after a rest?
Honestly, the Luscious Vanilla Banana Walnut Cake tastes amazing fresh, but letting it rest overnight allows the flavors to deepen and the crumb to become even more tender. If you can resist, make it ahead and let it chill in the fridge—divine!

Ingredients
Dry Ingredients
- 2 cups all-purpose flour
- 2 tsp baking soda
- 1/2 tsp salt
- 1/2 tsp cinnamon (optional)
Wet Ingredients
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar (or 1/2 cup white + 1/2 cup brown sugar)
- 2 large eggs
- 1 tsp vanilla extract
- 1/2 cup sour cream or plain yogurt
- 3 ripe bananas, mashed (about 1 cup)
Add-Ins & Toppings
- 1/2–3/4 cup chopped walnuts (plus extra for garnish)
- 2 cups creamy custard or cream cheese frosting
- Banana slices (for garnish)
Instructions
- Prepare the Oven & Pan: Preheat your oven to 350°F (175°C). Grease or line an 8–9″ round cake pan to prevent sticking and ensure easy removal.
- Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, salt, and cinnamon (if using) until evenly combined. Set aside.
- Cream Butter and Sugar: In a large mixing bowl, beat the softened butter with the sugar (or sugar blend) on medium speed until the mixture is light and fluffy, which should take about 2–3 minutes. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
- Add Bananas and Sour Cream: Blend in the sour cream (or yogurt) and mashed bananas, stirring until everything is well incorporated. The mixture might look slightly curdled, which is normal.
- Combine and Fold: Add the dry ingredients to the wet ingredients and stir gently until just combined to avoid overmixing. Fold in the chopped walnuts evenly throughout the batter.
- Bake: Pour the batter into your prepared pan and smooth the surface with a spatula. Bake for 35–45 minutes, or until a toothpick inserted into the cake’s center comes out clean or with a few moist crumbs attached.
- Cool and Frost: Remove the cake from the oven and let it cool in the pan for about 10 minutes, then turn it out onto a wire rack to cool completely. Once cooled, spread the creamy custard or cream cheese frosting in an even layer over the top.
- Garnish and Serve: Decorate with extra chopped walnuts and banana slices. Chill briefly to set the frosting, then slice and serve your luscious cake.
Notes
- Using both brown and white sugar deepens flavor and adds extra moisture, but use any sugar combination you prefer.
- If using custard as a topping, make sure it is cool and thick enough to spread.
- The cake stays moist for days—store covered in the refrigerator if topped with frosting or custard.
- Fold in walnuts gently to retain a pleasant crunch.
- This cake is also delicious unfrosted or with a dusting of powdered sugar.
