# Expert Advice:

01 -
  • The bananas do double duty here, adding natural sweetness and keeping every cookie impossibly soft for days.
  • You probably have every single ingredient in your kitchen right now, no grocery run required.
02 -
  • Underbaking by one minute is always better than overbaking, the cookies firm up considerably as they cool and you want that chewy center to survive.
  • If your bananas are not quite ripe enough, pop them in a 300 degree F oven for 15 minutes and the skins will blacken while the flesh turns syrupy sweet inside.
03 -
  • Mash the bananas on the finer side, any large chunks create wet spots in the baked cookie that can fall apart.
  • Rotate your baking sheet halfway through baking if your oven has hot spots, even browning makes a noticeable difference in both appearance and texture.
