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, allowing some excess paper to hang over the sides for easy removal later.
Step 2: Prepare the Batter
In a large bowl, beat together:
1. Sugar
2. Sour cream
3. Butter (the ½ cup)
4. Egg
Continue mixing until creamy and smooth. Then blend in:
– Mashed bananas
– Vanilla extract
Step 3: Combine Dry Ingredients
Add:
– All-purpose flour
– Baking soda
– Salt
Stir together until just combined; do not over-mix. Spread the batter evenly into the prepared pan.
Step 4: Bake the Bars
Bake in your preheated oven for about 20 to 25 minutes or until golden brown on top. Allow them to cool slightly before removing from the pan using the parchment paper.
Step 5: Make Brown Butter Icing
In a medium saucepan over medium-high heat, melt:
– The remaining ¼ cup of butter
Let it cook until it turns golden brown with small bits forming at the bottom; swirl occasionally but 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: Ice Your Bars
Once the banana bars have cooled for about 10–15 minutes (they should still be warm), spread the brown butter icing generously on top for that perfect finishing touch!

Common Mistakes to Avoid

- Overmixing the batter: This can lead to tough bars. Mix until just combined to keep them moist and tender.
- Ignoring oven temperature: Ovens can vary; always preheat to ensure even baking. Use an oven thermometer if necessary.
