Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.

In a large mixing bowl, mash the ripe bananas until smooth. Add the nut butter, honey (or maple syrup), and vanilla. Stir well to combine.

Add the oats, cinnamon, salt, coconut flakes, and any optional add-ins (like chocolate chips or flaxseed). Stir until everything is well mixed. The dough will be thick and sticky.

Use a cookie scoop or spoon to drop 2-tablespoon portions onto the baking sheet. Flatten slightly with the back of a spoon or your fingers—they won’t spread much while baking.

Bake for 12–15 minutes, or until the cookies are set and lightly golden on the bottom.

Sprinkle sea salt over top, if desired. Let cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
