Common Mistakes to Avoid
Baking Banana Bars with Brown Butter Icing can be a delightful experience, but avoiding common mistakes is crucial for success.
- Skipping the ripeness check: Always use very ripe bananas for the best flavor and moisture. If your bananas are not ripe enough, they won’t blend well or provide that sweet taste.
- Overmixing the batter: Mixing too much can lead to dense bars. Stir gently until just combined for a light texture.
- Not measuring ingredients accurately: Use proper measuring tools. Inaccurate measurements can drastically change the outcome of your bars.
- Ignoring cooling time: Allow the bars to cool slightly before icing them. This helps the icing spread evenly and creates a perfect melt-in-your-mouth effect.
- Using cold butter: If using brown butter, let it cool slightly before mixing into your icing. Hot butter can cause the powdered sugar to dissolve too quickly.

Storage & Reheating Instructions
Refrigerator Storage
