Storage and Make-Ahead
Once completely cooled, store the cookies in an airtight container at room temperature for 2–3 days, or in the refrigerator for up to 5 days. They’ll be soft and slightly chewy. For longer storage, freeze them in a single layer, then transfer to a freezer bag; thaw at room temperature or warm briefly in the microwave before serving.
FAQs
Can I use quick oats instead of rolled oats?
Yes, quick oats will work and give a slightly softer texture. Avoid instant oats, which can make the mixture too gluey.
Can I substitute another nut or seed butter?
Absolutely. Almond butter, cashew butter, or sunflower seed butter all work well; just make sure they’re creamy and well stirred.
Can I use other fruits?
You can replace blueberries with raspberries, chopped strawberries, or dried fruit like raisins or cranberries; just keep the overall quantity similar.
Are these cookies very sweet?
They’re lightly sweet from the bananas and any natural sweetness in your peanut butter. If you like a sweeter cookie, you can mix in a tablespoon or two of maple syrup or honey (if not strictly sugar‑free).
