How to Make Banana Bars with Brown Butter Icing
Step 1: Preheat the Oven
Heat oven to 375F. Line an 8×8 baking dish with parchment paper. I recommend overlapping two pieces so the sides hang over the pan for easy removal later.
Step 2: Prepare the Batter
In a large bowl, beat together sugar, sour cream, butter, and egg until creamy. Blend in mashed bananas and vanilla extract until well combined.
Step 3: Combine Dry Ingredients
Add flour, baking soda, and salt to the mixture. Stir together until just combined to avoid overmixing.
Step 4: Bake the Bars
Spread the batter evenly into the prepared pan. Bake for 20 to 25 minutes or until golden brown on top. Let cool slightly before removing from the pan using the parchment paper.
Step 5: Make Brown Butter Icing
In a medium saucepan, melt butter over medium-high heat. Continue cooking until brown bits form at the bottom; swirl the pan occasionally for even cooking.
Step 6: Whisk Together Icing Ingredients
Pour browned butter into a heat-proof bowl. Whisk in powdered sugar and vanilla until smooth.
Step 7: Frosting Time!
Spread icing on warm bars after they have cooled for about 10-15 minutes. The warmth helps create a slightly melty effect that enhances flavor.

How to Perfect Banana Bars with Brown Butter Icing
To achieve the best banana bars with brown butter icing, follow these simple tips. Each step will ensure your bars turn out moist and flavorful.
- Use Ripe Bananas: The riper the bananas, the sweeter and more flavorful your bars will be. Look for bananas that are mostly brown.
- Don’t Overmix: Mix just until combined when adding flour to keep your bars tender and fluffy.
- Monitor Baking Time: Check your bars often towards the end of baking to avoid overcooking; they should be golden but not dry.
- Cool Before Icing: Allow your bars to cool slightly before adding icing; this helps it spread smoothly without melting away.

Common Mistakes to Avoid
When making Banana Bars with Brown Butter Icing, it’s easy to stumble on a few common issues. Here’s what to watch out for:
- Using underripe bananas: Make sure to use very ripe bananas, as they provide the best flavor and moisture for your bars. Overripe bananas are ideal since they are sweeter and softer.
- Not measuring ingredients accurately: Improper measurements can lead to dense or dry bars. Use proper measuring cups and spoons for accuracy.
- Skipping the parchment paper: Not lining your baking dish can make it difficult to remove the bars. Always use parchment paper for easy lifting.
- Overmixing the batter: Mixing too much can result in tough bars. Stir until just combined for a light, moist texture.
- Not letting the bars cool before icing: Icing hot bars can cause it to melt away. Allow them to cool for about 10-15 minutes before spreading the icing.
