Chef Tips from the Video

- For extra flavor, toast the rolled oats lightly before mixing.
- Add a pinch of cinnamon or vanilla extract for a subtle aromatic boost.
Troubleshooting
Bars are crumbly and fall apart.

Mixture is too sticky to spread.
Lightly wet the spatula or press with a piece of parchment between the mixture and the tool.
