Ingredients
For the Bars
- 1/2 cup/1 stick of butter
- ¾ cup sugar
- ½ cup sour cream
- ¼ cup butter, softened
- 1 egg
- 1 cup (about 2) very ripe bananas, mashed
- 1 tsp. vanilla extract

- ½ tsp. baking soda
- ½ tsp. salt
For the Brown Butter Icing
- 2 cups powdered sugar
- 1 tsp. vanilla extract
- 1½ tbsp. milk
How to Make Banana Bars with Brown Butter Icing
Step 1: Preheat the Oven
Heat your oven to 375°F (190°C). Line an 8×8 baking dish with parchment paper. Overlapping two pieces works best so that the sides hang over the pan, making it easy to lift out the bars later.
Step 2: Mix Wet Ingredients
In a large bowl, beat together:
1. Sugar
2. Sour cream
3. Softened butter
4. Egg
Continue mixing until creamy. Then blend in:
– Mashed bananas
– Vanilla extract
Step 3: Combine Dry Ingredients
Add:
– All-purpose flour
– Baking soda
– Salt
Stir until just combined without overmixing. Spread this batter evenly into your prepared baking pan.
Step 4: Bake the Bars
Bake for 20 to 25 minutes or until golden brown on top. Once done, let cool slightly before using the parchment paper to lift them out of the pan.
Step 5: Prepare Brown Butter Icing
In a medium saucepan over medium-high heat:
1. Melt butter while swirling occasionally.
2. Let it cook until brown bits form at the bottom—keep an eye on it so it doesn’t burn.
Step 6: Mix Icing Ingredients
Pour the browned butter into a heat-proof bowl and whisk in:
– Powdered sugar
– Vanilla extract
– Milk
Mix until smooth.
Step 7: Frosting Application
After letting the bars cool for about 10–15 minutes, spread the icing on top. The frosting goes on easier when slightly warm and creates a wonderfully soft texture.

- Use very ripe bananas: The riper your bananas, the sweeter and more flavorful your bars will be.
- Don’t overmix: Gently stir in the flour until just combined to avoid dense bars.
- Check for doneness: Insert a toothpick into the center; it should come out clean or with a few crumbs attached.
- Cool before icing: Allow the bars to cool slightly before spreading on the icing for better adherence.
- Store properly: Keep leftover bars in an airtight container at room temperature to maintain moisture.

Common Mistakes to Avoid
Making Banana Bars with Brown Butter Icing can be a delightful experience, but a few common pitfalls can affect your results.
- Using unripe bananas: Always choose very ripe bananas for the best flavor and moisture. Overripe bananas contribute natural sweetness and a soft texture.
- Not cooling the bars enough: If you don’t let the bars cool before icing, the frosting may melt off. Allow them to cool for at least 10-15 minutes.
- Overmixing the batter: Mixing too much can lead to dense bars. Stir just until the ingredients are combined for a lighter texture.
- Incorrect oven temperature: Baking at the wrong temperature can cause uneven cooking. Use an oven thermometer to ensure it’s set correctly.
- Skipping parchment paper: Not using parchment paper can make it difficult to remove the bars from the pan. Always line your baking dish for easy lifting.
