Common Mistakes to Avoid
Making Banana Bars with Brown Butter Icing can be a delightful experience. However, there are some common mistakes to watch out for.
- Using unripe bananas: Unripe bananas do not provide the sweetness and moisture needed for the bars. Always use very ripe bananas for the best flavor.
- Overmixing the batter: Overmixing can lead to dense bars. Mix until just combined to keep them light and fluffy.
- Skipping the parchment paper: Not lining your baking dish can make it difficult to remove the bars. Always line with parchment for easy lifting.
- Not cooling before icing: Applying icing on hot bars can cause it to melt away. Allow your bars to cool for at least 10-15 minutes before icing.
- Ignoring baking time: Every oven is different; check your bars a few minutes early. Bake until they are golden brown for optimal texture.
