‘Shockingly easy’: Just 3 ingredients. I’ve made it enough times to skip measuring entirely.

Because this recipe is so simple, small adjustments can change the character of the cookies quite a bit. For extra flavor without adding more ingredients, toast the oats lightly in a dry skillet over medium heat for a few minutes before mixing; this brings out a nutty aroma that makes the cookies taste more complex. If you’d like a bit more texture, stir in 2–3 tablespoons of chopped nuts (walnuts, pecans, or almonds) while keeping the base to three primary ingredients. You can also swap the chocolate chips for raisins or dried cranberries for a more breakfast-leaning cookie, or use dark chocolate chips if you prefer less sweetness. For a firmer cookie, add an extra tablespoon or two of oats, especially if your bananas are very large or particularly soft. To coax more caramelized flavor, let the cookies bake an extra minute or two, watching carefully so the bottoms don’t scorch. Finally, if you’re cooking for kids or anyone new to “banana-only” cookies, bake a small test cookie first; adjust the size, baking time, or amount of oats until you land on the texture you like best—chewier, softer, or a bit more structured.
