Common Mistakes to Avoid
When making Banana Peanut Butter Oat Bars, it’s easy to run into a few common pitfalls. Here are some mistakes to watch out for.
- Not using ripe bananas: Ripe bananas provide natural sweetness and better texture. Always choose bananas that are speckled brown for the best flavor.

- Overmixing the batter: Overmixing can lead to tough bars. Mix just until everything is combined for a softer texture.
- Not measuring ingredients accurately: Accurate measurements are key for the right consistency. Use measuring cups and spoons to ensure you have the correct amounts.
- Ignoring baking time: Every oven is different. Keep an eye on your bars as they bake, and check for doneness around 28 minutes.
