Step 1

Preheat oven to 350F degrees. Spray a baking sheet with nonstick spray or line (parchment, foil, silpat).

Step 2

In a medium bowl, mash the bananas with a fork until almost no lumps remain (the mixture should be almost liquid if using really ripe bananas; you should have about 1 cup). Stir in the oats until well-blended. Let the mixture stand for 5 minutes. Mix in any optional ingredients, if using.

Step 3

Using a small cookie scoop or rounded tablespoon measure, drop rounded tablespoons onto prepared baking sheet about 1 inch apart. Press down for flatter cookies (they don’t really spread). Sprinkle with any of the suggested toppings, if desired.Bake in preheated oven for 15 to 18 minutes until golden brown and firm to touch at the center. Transfer to cooling rack and cool completely.
