The History and Origins of Banana Walnut Cake
Banana cakes have roots in American home baking, particularly in the South, where resourceful cooks turned overripe bananas into sweet treats during times when wasting food wasn’t an option. Banana bread became popular in the 1930s with the rise of baking soda and powder, but evolving it into a frosted cake added a celebratory twist.
This particular style—with walnuts, cream cheese frosting, and fresh banana garnishes—draws inspiration from classic banana nut breads and cakes popularized by figures like Paula Deen. It’s similar to hummingbird cake (which adds pineapple) but keeps things simple and focused on pure banana flavor with nutty crunch.
Walnuts add an earthy, slightly bitter contrast to the sweetness of bananas, making each bite more complex. The cream cheese frosting, tangy and rich, balances the moisture from the fruit perfectly. This cake has been a staple in family recipe boxes for decades, and once you try it, you’ll understand why it’s endured.

Key Ingredients and Why They Matter
To make this cake truly exceptional, quality ingredients are key. Here’s a breakdown:
- Ripe Bananas: The star of the show. Use very ripe bananas with lots of brown spots—they’re sweeter and mash easily, providing natural moisture and intense banana flavor. Aim for 4-5 large bananas (about 2 cups mashed).
- Walnuts: Toasted for extra flavor, they add crunch and nuttiness. About 1.5 cups chopped, plus more for topping.
- All-Purpose Flour: Provides structure. We’ll use 3 cups for the batter.
- Butter and Oil: A combo for richness and moisture. Unsalted butter for flavor, vegetable oil to keep it tender.
- Eggs: 4 large eggs for binding and lift.
- Sugars: Granulated and brown sugar for sweetness and moisture.
- Leaveners: Baking soda and powder for rise.
- Spices: Cinnamon and a touch of nutmeg for warmth.
- Buttermilk or Sour Cream: Adds tang and extra tenderness.
For the frosting:
- Cream cheese, butter, powdered sugar, vanilla, and heavy cream for smoothness.
Fresh bananas and walnuts for garnish complete the look and taste.
Substitutions: Use pecans instead of walnuts, or add a handful of chocolate chips for a twist.

Step-by-Step Instructions: How to Make the Cake
Step 1: Prepare Your Pans and Preheat the Oven
Start by preheating your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter or non-stick spray, then line the bottoms with parchment paper for easy release. Dust the sides with flour if desired.
Toasting the walnuts enhances their flavor immensely. Spread 2 cups of chopped walnuts on a baking sheet and toast in the oven for 8-10 minutes until fragrant. Let them cool, then set aside.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. This ensures even distribution of leaveners and spices. Set aside.
Step 3: Cream the Butter, Oil, and Sugars
In a large mixing bowl (or stand mixer fitted with paddle attachment), beat the softened butter, oil, granulated sugar, and brown sugar on medium-high speed for 3-4 minutes until light and fluffy. This incorporates air for a tender crumb.
Step 4: Add Eggs and Vanilla
Add the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Mix in the vanilla extract.
Step 5: Incorporate Bananas and Buttermilk
On low speed, add the mashed bananas and mix until combined. The batter may look curdled—don’t worry, it’s normal! Alternate adding the dry ingredients in three parts with the buttermilk in two parts, starting and ending with dry. Mix just until incorporated to avoid overmixing.
Step 6: Fold in Walnuts
Gently fold in 1 cup of the toasted chopped walnuts with a spatula. This preserves the air in the batter.
Step 7: Bake the Cakes
Divide the batter evenly between the prepared pans. Bake for 28-35 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Rotate pans halfway for even baking.
Cool in pans for 10 minutes, then turn out onto wire racks to cool completely (at least 2 hours). If baking as a single layer in a 9×13 pan, bake 40-50 minutes.

Making the Perfect Cream Cheese Frosting
While the cakes cool, prepare the frosting—it’s the crowning glory!
Beat the softened cream cheese and butter together on medium speed until smooth and creamy, about 2 minutes. No lumps allowed!
Gradually add the sifted powdered sugar, 1 cup at a time, on low speed to avoid a sugar cloud. Once incorporated, increase speed to medium-high and beat for 2-3 minutes until fluffy.
Add vanilla, salt, and heavy cream 1 tablespoon at a time until you reach a spreadable consistency. It should hold peaks but be easy to spread. If too thin, add more powdered sugar; if too thick, more cream.
This makes enough to generously frost a two-layer cake. For extra tang, add a squeeze of lemon juice.
Tips for success: Use full-fat cream cheese for stability. Chill the frosting briefly if it’s too soft in warm weather.

Assembling and Decorating the Cake
Once cakes are completely cool:
- Level the tops if domed using a serrated knife for even layers.
- Place one layer on a cake stand or plate. Spread about 1-1.5 cups frosting evenly on top.
- Add the second layer (bottom side up for a flat top).
- Crumb coat: Spread a thin layer of frosting over the entire cake to seal in crumbs. Chill 15-30 minutes.
- Apply the final thick layer of frosting on top and sides, swirling decoratively with an offset spatula.
- For the signature look: Arrange fresh banana slices in a circular pattern on top, starting from the center.
- Sprinkle toasted walnuts generously over the bananas and around the edges.
- Optional: Mix a simple glaze and drizzle over the top for that glossy, dripping effect seen in gourmet versions.
Press extra walnuts into the sides for a rustic touch if desired.
Chill the assembled cake for 30 minutes to set before slicing.

Tips and Tricks for the Best Results
- Banana Ripeness: The blacker, the better! Freeze overripe bananas and thaw for baking—they release more liquid for moisture.
- Don’t Overmix: This leads to tough cake. Mix until just combined.
- Room Temperature Ingredients: Eggs, butter, and cream cheese at room temp ensure smooth incorporation.
- Toasting Nuts: Always toast walnuts—they taste bland raw.
- Make Ahead: Bake layers a day ahead, wrap tightly, and frost the next day. Flavors improve overnight.
- Freezing: Unfrosted layers freeze well up to 3 months. Frosted cake freezes but garnishes (fresh bananas) won’t.
- Avoid Soggy Top: Add fresh banana slices just before serving to prevent browning and excess moisture.
- High Altitude Adjustments: Reduce leaveners slightly and increase liquid if needed.
Common mistakes: Using underripe bananas (bland cake) or overbaking (dry texture).
