FAQs

A2: No, ripe bananas provide natural sweetness. You can add honey or maple syrup if you want them sweeter.

Q3: Can I make these cookies gluten-free?
A3: Yes, just use certified gluten-free rolled oats to keep them safe for gluten-sensitive diets.

Q4: How ripe should the bananas be?
A4: The riper the better! Bananas with lots of brown spots are sweetest and mash easily.

Q5: Can I double or triple the recipe?
A5: Absolutely. Keep the ingredient ratios the same and bake in batches as needed.
