Notes
- Use very ripe bananas for natural sweetness and moisture.
- Natural peanut butter works best to keep the flavors rich and smooth.
- Instant or quick cooking oats provide a better texture; rolled oats can be used but will produce a denser bar.
- Chocolate chips add a delightful sweetness but can be omitted or replaced with nuts for a healthier option.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate to keep longer.
