Step-by-Step Instructions
Step 1: Preheat & Prepare Pans
Preheat your oven to 350 °F (175 °C). Grease and flour two 9-inch round cake pans (or line with parchment). This ensures smooth release and even baking.
Step 2: Toast the Walnuts
In a dry skillet over medium heat, toast the chopped walnuts until fragrant (~3-4 minutes), stirring constantly. Let them cool before folding into the batter. Toasting boosts their essential oils and aroma.
Step 3: Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside. Ensuring leaveners are evenly distributed helps uniform rise.
Step 4: Cream Butter, Sugar & Eggs
In a large bowl or stand mixer, beat the softened butter and granulated sugar until pale and fluffy (about 3-4 minutes). Add eggs one at a time, then vanilla extract. This stage incorporates air for lift and light crumb.
Step 5: Add Bananas & Buttermilk
Stir in the mashed bananas and butter-milk mixture until just combined. The mashed banana gives natural sweetness and banana flavor; buttermilk ensures a tender texture.
Step 6: Combine Wet & Dry, Fold in Walnuts
Alternate adding the dry mixture and remaining wet ingredients (if any) into the butter mixture, beginning and ending with dry ingredients. Gently fold in the toasted walnuts. Avoid over-mixing to keep the crumb light.
Step 7: Bake the Cake
Divide batter evenly between the prepared pans. Bake for ~30-35 minutes or until a toothpick inserted in the centre comes out clean with a few moist crumbs. Let cakes cool in pans for 10 minutes, then turn out onto a rack to cool completely.
Step 8: Prepare Banana Filling & Whipped Cream Frosting
While cakes cool:
-
Toss the sliced bananas with lemon juice and optional brown sugar; set aside.
-
Chill a mixing bowl and beaters for 10 minutes, then whip heavy cream, powdered sugar, and vanilla until stiff peaks form. This gives you a light, creamy filling and frosting that complements the dense cake layers.
Step 9: Assemble the Cake
Once cake layers are fully cool:
-
Place first layer on your cake stand, spread a generous layer of whipped cream, then top with banana slices.
-
Place second cake layer on top, cover entire cake with remaining whipped cream.
-
Garnish with extra walnuts, banana slices, chocolate shavings or caramel drizzle for presentation.
Step 10: Chill & Serve
Chill the assembled cake for at least 1 hour before slicing. This helps the layers set, flavors marry and provides clean slices. Serve chilled or at room temperature depending on preference.

Using ripe bananas boosts natural sweetness and moisture — according to nutrition data, bananas also provide potassium and dietary fibre, making this cake slightly more nutrient-dense than a standard vanilla butter cake.
Healthier Alternatives for the Recipe
-
Reduce Sugar: Replace half the granulated sugar with coconut sugar or maple syrup; use ¼ cup powdered sugar in frosting instead of ½ cup.
-
Lower Fat: Use half butter and half Greek yogurt in the batter; switch heavy cream to light cream or whipped aquafaba for nondairy.
-
Gluten-Reduced/Dairy-Optional: Replace all-purpose flour with a gluten-free flour blend; swap heavy whipping cream for coconut cream; use dairy-free butter.
-
Nut-Free Version: Omit walnuts or substitute with toasted sunflower seeds if nut allergy is a concern, maintaining crunch.
-
Extra Fruit & Fiber: Add ½ cup mashed Greek yogurt or applesauce in place of some butter; fold in ½ cup grated carrot for added moisture and nutrition.
Serving Suggestions

-
Serve a slice with a scoop of vanilla ice cream and a drizzle of warm caramel sauce for an indulgent twist.
-
For a brunch option: pair with a side of mixed berries and a light latte or herbal tea.
-
For a festive presentation: top with fresh banana slices and chopped walnuts at the table, letting guests sprinkle themselves.
-
Leftover idea: Use cake crumbs in a parfait layered with Greek yogurt and banana slices for next-day breakfast or snack.
Common Mistakes to Avoid
-
Using underripe bananas: Missed opportunity for natural sweetness — overripe bananas yield better flavor and moist cake.
-
Over-mixing batter: Leads to dense, tough texture; mix only until ingredients are just combined.
-
Skipping cooling before frosting: Warm cake layers will melt whipped cream and ruin presentation.
-
Not toasting walnuts: Raw nuts can taste flat—toast enhances aroma and texture.
-
Serving immediately: The cake benefits from a chill period to let layers set; serving too soon may result in squished layers or runny filling.
Storing Tips for the Recipe
-
Refrigeration: Store in an airtight cake container or cover loosely with plastic wrap; keep in fridge for up to 2-3 days. The whipped cream frosting means refrigeration is required.
-
Freezing: Freeze individual slices wrapped in plastic-wrap and foil; freeze up to 1 month. Thaw overnight in fridge and serve chilled.
-
Make-Ahead: Bake the cake layers a day ahead, wrap in plastic, and assemble next day. This saves time and flavors deepen overnight.
-
Serving Room Temperature: Remove from fridge ~20 minutes before serving for best texture and flavor.

FAQs
Q1: Can I use frozen bananas for this cake?
Yes — thaw and drain excess liquid before mashing to avoid overly wet batter. Overripe frozen bananas work great for flavor.
Q2: What size cake pans should I use?
Use two 9-inch round pans for this recipe. If you only have an 8-inch pan, reduce baking time and monitor closely.
Q3: How far ahead can I assemble the cake?
You can bake the layers up to 24 hours in advance, but assemble with whipped cream frosting on the day of serving for best texture.
Q4: Can I substitute the whipped cream frosting with cream cheese frosting?
Yes — cream cheese frosting adds tang and stability, which is good if you can’t serve right away or need a firmer topping.
Q5: My cake sank in the middle — what happened?
Possible causes: under-baking, opening the oven too early, or over-mixing. Ensure oven is properly preheated and check for doneness before removing.
