Common Mistakes to Avoid

- Not measuring ingredients properly: Accurate measurements are key. Use measuring cups and spoons for precision, especially for oats and peanut butter.
- Skipping the baking powder: Baking powder helps the bars rise. Don’t skip it, as it contributes to a better texture.
- Ignoring cooling time: Letting the bars cool is important for cutting. If you cut them too soon, they may crumble.
