Step-by-Step Instructions

Preheat and Prepare Pans:
Preheat your oven to 350 degrees Fahrenheit, approximately 175 degrees Celsius. Grease and flour two nine-inch round cake pans or line them with parchment paper to ensure the cakes release easily after baking and bake evenly.
Toast the Walnuts:
Place the chopped walnuts into a dry skillet over medium heat. Stir constantly and toast for about three to four minutes, until they release a fragrant aroma. Let them cool fully before adding to the batter so they keep their crunch.
Mix Dry Ingredients:
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures the leavening agents are evenly distributed throughout the flour for consistent rising.
Cream Butter Sugar and Eggs:
In a large bowl or stand mixer, beat the softened butter with the granulated sugar until the mixture is pale in color and fluffy. This will take about three to four minutes and creates air bubbles that lighten the cake. Add eggs one at a time, beating well after each addition, then stir in the vanilla extract.
Add Bananas and Buttermilk:
Fold the mashed bananas into the butter mixture along with the buttermilk until just combined. The bananas provide natural sweetness and moisture, while the buttermilk reacts with the baking soda to create tenderness.
Combine Wet and Dry Ingredients and Fold in Walnuts:
Alternate adding the dry mixture and any remaining wet ingredients into the butter mixture, starting and ending with the dry. Fold gently to avoid overmixing, then fold in the toasted walnuts carefully so they are distributed but the batter remains light.
Bake the Cake:
Divide the batter evenly between the prepared pans. Bake for about thirty to thirty-five minutes. Insert a toothpick into the center to check doneness; it should come out clean with a few moist crumbs. Allow the cakes to cool for ten minutes in the pans before removing them to a wire rack to cool completely.
Prepare Banana Filling and Whipped Cream Frosting:
While the cakes cool, mix the sliced bananas with lemon juice and optional brown sugar. Set aside to macerate slightly. Chill your mixing bowl and beaters, then whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
Assemble the Cake:
Place one cooled cake layer on your serving plate. Spread a generous layer of whipped cream over it, then add the banana slices. Top with the second cake layer and cover the entire cake with the remaining whipped cream. Garnish with walnuts, banana slices, or chocolate shavings as desired.
Chill and Serve:
Refrigerate the assembled cake for at least one hour before serving. This allows the layers to set and flavors to meld. Serve chilled or allow the cake to come to room temperature about twenty minutes before slicing for the best texture.

The toasted walnuts are one of my favorite parts. Toasting them brings out an irresistible aroma that pairs beautifully with the sweetness of the bananas. I still remember the first time I toasted walnuts for this cake—it filled the kitchen with such a warm nutty scent that I knew it was going to be something special.

Storage Tips

Store the cake covered loosely or in an airtight container in the refrigerator for up to three days to keep the whipped cream fresh. For longer storage, wrap individual slices in plastic wrap and foil and freeze them for up to a month. Thaw slices overnight in the fridge before serving.

Ingredient Substitutions

To reduce sugar, try swapping half the granulated sugar with coconut sugar or maple syrup and reduce the powdered sugar in the frosting. For a lower fat version, replace half the butter with Greek yogurt and use light cream instead of heavy whipping cream. Use gluten-free flour blends and coconut cream for dairy-free or gluten-free variations. If nut allergies are an issue, substitute walnuts with toasted sunflower seeds to maintain crunch.

Serving Suggestions

Serve this cake with a scoop of vanilla ice cream and a drizzle of warm caramel sauce for an indulgent dessert. For brunch, pair a slice with fresh mixed berries and a light latte or herbal tea. Leftovers make a great parfait layered with Greek yogurt and banana slices for a tasty next-day treat.

→ How far ahead can the cake be assembled?

Bake layers up to 24 hours ahead. Assemble with whipped cream frosting on serving day for best texture and appearance.

→ Can cream cheese frosting replace whipped cream?

Yes, cream cheese frosting adds a tangy flavor and firm texture, ideal if the cake needs longer storage or firmer topping.

Step-by-Step Directions

Step 01

Preheat oven to 175 °C. Grease and flour two 23 cm round cake pans or line them with parchment paper for easy release.

Step 02

Toast chopped walnuts in a dry skillet over medium heat for 3-4 minutes until fragrant, stirring constantly. Allow to cool.

Step 03

In a medium bowl, whisk together flour, baking powder, baking soda, and salt to ensure even distribution of leavening agents.

Step 04

In a large bowl or stand mixer, beat softened butter and granulated sugar until pale and fluffy, about 3-4 minutes. Add eggs one at a time, then mix in vanilla extract.

Step 05

Stir mashed bananas and buttermilk into the butter mixture until just combined, preserving moisture and flavor.

Step 06

Alternately fold dry mixture and any remaining wet ingredients into batter, beginning and ending with dry ingredients. Gently fold in toasted walnuts without over-mixing to maintain a light crumb.

Step 07

Divide batter evenly between prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean with a few moist crumbs. Cool in pans for 10 minutes, then invert onto a rack to cool completely.

Helpful Notes

  1. Use overripe bananas to maximize natural sweetness and moisture. Allow cake layers to cool completely before frosting to prevent melting and preserve presentation.
  2. Chilling the assembled cake helps layers to set and provides clean slices.
  3. For a dairy-free version, replace butter with dairy-free alternatives, buttermilk with plant-based milk plus lemon juice, and heavy cream with chilled coconut cream.
