Common Mistakes to Avoid
Making Banana Bars with Brown Butter Icing can be a delightful experience, but there are common pitfalls to watch out for.
- Boldly forget about ripeness: Using unripe bananas will not give you that sweet, natural flavor. Always select very ripe bananas for the best results.
- Mix too much: Overmixing the batter can lead to dense bars. Mix just until combined to keep them light and fluffy.
- Skip cooling: Frosting warm bars can make a mess of your icing. Allow the bars to cool slightly before adding the icing for a smoother finish.
- Neglect baking time: Every oven is different. Check your bars at the 20-minute mark to avoid overbaking and ensure they stay moist.
- Use wrong pan size: Using a pan that’s too small can cause overflow, while a larger one may result in thin bars. Stick to an 8×8 inch dish for ideal thickness.
