Preheat oven to 350°F. Line a baking sheet with parchment paper or silpat mat and set aside.
Add mashed banana, seed butter, water and vanilla to a medium-sized mixing bowl. Mix to combine. Add coconut flour, oats, cinnamon, salt, raisins and zucchini and mix until oats are well moistened. It may be easier to use your (clean) hands!
Scoop out about 1 1/2 tablespoons of dough and roll into a ball. Flatten with the palms of your hand and place on the prepared baking sheet. Cookies will not spread much, so you only need to leave about 1 inch in between each cookie. Repeat until all dough is used.
Bake at 350°F for 15 minutes, or until edges are golden brown. Let cool for a few minutes before transferring to a cooling rack.
