- 9×9-inch baking pan or round cake pans
- Small saucepan (for browning butter)
- Cooling rack (optional)
Ingredients
For the Banana Cake:
- 1 cup unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs (room temperature)
- 2 ½ teaspoons pure vanilla extract
- 2 ½ cups all-purpose flour
- 2 teaspoons baking soda
- ½ teaspoon salt
- 4 ripe medium bananas, mashed (about 2 cups)
For the Brown Butter Icing:
- ¾ cup unsalted butter, cubed
- 4 cups powdered sugar
- ¼ cup heavy cream or whole milk
- 2 teaspoons pure vanilla extract
How to Make Banana Cake with Brown Butter Icing
1. Preheat and Prepare:
Begin by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch cake pan (or line it with parchment paper for easy removal). If using round pans, also line the bottom with parchment and grease the sides.
2. Mix the Wet Ingredients:
In a large mixing bowl, cream the softened butter and sugar together until light and fluffy—this takes about 2–3 minutes with a mixer. Add the eggs one at a time, beating well after each addition. Then stir in the vanilla extract.
3. Add Bananas:
Fold in the mashed bananas to the wet mixture. It’s okay if the batter looks a little lumpy from the banana that’s where the flavor comes from.
4. Incorporate Dry Ingredients:
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing just until everything is combined. Don’t overmix—it will make the cake dense.
5. Bake the Cake:
Pour the batter into the prepared pan, spreading it evenly. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean. Cool the cake in the pan for about 10 minutes, then transfer to a wire rack to cool completely before icing.
6. Make the Brown Butter Icing:
In a saucepan over medium heat, melt the butter and let it cook, stirring frequently, until it turns golden brown and develops a nutty aroma—about 5–7 minutes. Remove from heat. Immediately whisk in the powdered sugar, heavy cream (or milk), and vanilla. Keep whisking until smooth and spreadable. Add more cream if needed to reach your desired consistency.
7. Ice the Cake:
Once the cake is completely cool, pour or spread the brown butter icing over the top. Use a spatula to smooth it out. The icing will set up slightly as it cools, giving it a lovely finish.
Special Notes
❖ Banana Ripeness: For the best results, use ripe bananas with plenty of brown spots. These will give the cake a natural sweetness and add extra moisture.
❖ Brown Butter: Don’t rush the brown butter process. It can quickly go from golden to burnt if you’re not careful, so keep an eye on it. If you accidentally burn the butter, you may need to start over with fresh butter.
❖ Icing Consistency: If you prefer a thicker frosting, reduce the milk in the icing. On the other hand, if you’d like a more glaze-like finish, increase the amount of milk for a thinner texture.

Why My Recipe Works
This Banana Cake with Brown Butter Icing works because it balances moisture, flavor, and texture beautifully. The ripe bananas keep the cake tender and naturally sweet, while the butter and eggs add richness and structure.
Baking soda reacts with the bananas to create a light, fluffy crumb. The brown butter icing brings a deep, nutty flavor that enhances every bite without overpowering it.
Simple ingredients come together in a thoughtful way, and each step builds on the last to create a cake that feels homemade, nostalgic, and incredibly satisfying.
What Is The Best Serving Ideas
1. Fresh Fruit on the Side: Serve slices with a handful of fresh berries (like raspberries or blueberries) or thin banana slices for a fresh contrast to the sweet icing.
2. Lightly Toasted Nuts: Top each slice with a few chopped toasted pecans or walnuts. The added crunch and nuttiness enhance the brown butter flavor beautifully.
3. Whipped Cream or Yogurt: A dollop of lightly sweetened whipped cream or vanilla Greek yogurt adds a creamy, cool element that balances the cake’s richness.
4. Drizzle of Caramel or Chocolate Sauce: A thin drizzle of warm salted caramel or dark chocolate sauce takes it to dessert-worthy heights, especially for special gatherings.
5. With a Cup of Coffee or Tea: This cake shines when served with a warm drink. The slightly bitter notes in coffee or an earthy tea (like Earl Grey or chai) cut through the sweetness and create a cozy pairing.
Health Benefits Of Banana Cake With Brown Butter Icing
Banana Cake with Brown Butter Icing offers some surprising health benefits, especially thanks to the bananas. Bananas provide essential vitamins like potassium and vitamin C, supporting heart health and digestion.
The natural sugars in ripe bananas reduce the need for added sweeteners, making the cake slightly less sugary than other desserts. Brown butter adds healthy fats and antioxidants from the toasting process.
While still a treat, this Banana Cake with Brown Butter Icing delivers nutrients alongside indulgence, making it a more wholesome choice when enjoyed in moderation.
How To Decorate Banana Cake With Brown Butter Icing
To decorate your banana cake with brown butter icing, spread the icing evenly over the cooled cake using a spatula for a smooth, glossy finish.
For added texture, sprinkle chopped walnuts on top, letting them gently fall over the edges. You can also garnish with a few fresh banana slices for a vibrant touch.
For a polished look, pipe the icing in decorative swirls around the edges or center. The warm, nutty flavor of the brown butter icing pairs beautifully with these simple, yet elegant toppings.
Recipe Tips And Techniques
1. Start by making sure your bananas are really ripe dark spots mean maximum sweetness and flavor. Using underripe ones will make the cake less moist and flavorful.
2. When creaming the butter and sugar, take your time. This step is key to a light, fluffy cake texture, so don’t rush it; it’s worth the extra minute or two.
3. I always add the dry ingredients gradually and fold them in gently. Overmixing makes the cake dense, so mix just until you don’t see streaks of flour.
4. Browning the butter requires attention watch it carefully and stir often. The moment it turns golden and smells nutty is when you want to remove it from the heat to avoid burning.
5. Cooling the cake completely before icing is crucial. Warm cake melts the icing, making it runny and messy, so patience here pays off with a neat finish.
6. Lastly, I like to store this cake wrapped tightly or in an airtight container. It actually tastes better the next day when the flavors have had time to meld.
Variations Of Banana Cake With Brown Butter Icing
1. Chocolate Chips: Add 1/2 cup of chocolate chips to the banana cake batter for a rich, chocolatey twist that complements the sweetness of the bananas.
2. Cinnamon Spice: Incorporate 1 teaspoon of ground cinnamon or a pinch of nutmeg into the dry ingredients for a warm, spiced flavor.
3. Cream Cheese Icing: Swap the brown butter icing with a tangy cream cheese frosting for a slightly different taste that pairs perfectly with banana.
4. Banana-Nut Swirl: Instead of just adding chopped walnuts to the batter, swirl some crushed walnuts and banana slices into the cake for added texture and flavor.
5. Caramel Drizzle: Drizzle homemade or store-bought caramel sauce over the top of the iced cake for an indulgent, sweet finish.
How To Store Leftovers
To store leftover Banana Cake with Brown Butter Icing, cover it tightly with plastic wrap or place it in an airtight container. This will help keep the cake fresh and prevent it from drying out.
Store it at room temperature for up to 2-3 days. If you want to keep it longer, you can refrigerate the cake for up to a week.
Before serving, let it come to room temperature for the best flavor and texture. For even longer storage, you can freeze the cake by wrapping it tightly in plastic wrap and aluminum foil, where it will stay fresh for up to 3 months.
