Combine banana and quick oats in a small bowl. Note: Quick oats are definitely recommended over standard oats.
Add nuts and combine. Note: Gina recommended walnuts in the original recipe, but I used pecans only because that’s what I had on hand.
Using a tablespoon, scoop out the dough and place on the cookie sheet, making 8 cookies.
Bake at 350 degrees for 15 minutes. Note: Cookies become a little bit browner than I expected, but they’re PERFECT that way!
