Preheat oven to 325°F/160°C. Line a large cookie sheet with parchment paper or a silicone baking mat.

In a large bowl, mash the ripe bananas until very smooth and liquid.

Add the peanut butter, rolled oats, and protein powder to the mashed bananas. Mix to combine.

Add the chia seeds, melted coconut oil, honey, chocolate chips, raisins, vanilla extract, cinnamon, and salt. Stir everything together until well combined.

Shape the mixture into 20 cookies and place on the prepared baking sheet. Flatten the cookies to about ½ inch thick.

Bake the cookies for about 10-12 minutes until set and the bottoms start to brown.

Let the cookies cool completely on a wire rack before transferring to an airtight container for storage.
