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