Banana everything cookies

This is a kitchen sink recipe that uses banana as a binder in lieu of eggs and butter, plus chocolate chips, walnuts, and oats. We tried this recipe: https://cooking.nytimes.com/recipes/1012904-banana-everything-cookies?smid=ck-recipe-iOS-share We used 1 large, ripe banana. Instead of spraying the baking sheets with oil, we lined with parchment, which we then sprayed with corn oil. We found this recipe yielded 27 cookies. We forgot to slightly flatten the cookies before baking them, so we baked at 350 for about 14 mins. Then, following the instructions, we let cool on the baking sheets for 2 mins before transferring to a cooling rack. (May 2020)
