01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - In a large bowl, mash the bananas until smooth. Whisk in melted coconut oil, honey or maple syrup, egg, and vanilla extract until well combined.
03 - In a separate bowl, stir together the rolled oats, flour, baking soda, ground cinnamon, and salt until evenly distributed.
04 - Fold the dry ingredient mixture into the wet ingredients until just combined. Stir in chocolate chips and nuts if using, being careful not to overmix.
05 - Drop heaping tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. Slightly flatten each cookie with the back of a spoon or your fingers.
06 - Bake for 13–15 minutes, or until the cookies are set and lightly golden around the edges.
07 - Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before serving or storing.
