Preheat oven to 350°F. Line a baking sheet with parchment paper and set aside.

In a large bowl, add bananas and mash until smooth. Add the peanut butter, maple syrup, butter, egg, and vanilla. Whisk until well incorporated.

Add the oats, baking powder, baking soda, and cinnamon. Using a rubber spatula, stir and fold until well mixed. Fold in raisins, chocolate chips and walnuts.

Using a 2-tablespoon cookie scoop, drop cookie dough onto prepared baking sheet, about 1-2 inches apart. Using a fork, flatten each cookie to desired thickness. They won’t spread much during baking.

Bake for 9-11 minutes. Allow to cool on the baking sheet for a few minutes before transferring to a cooling rack. Allow to cool completely. Enjoy!
