In a medium mixing bowl, add mashed bananas and peanut butter. Stir with a spatula until banana is fully incorporated into the peanut butter and your mixture becomes a thick paste. The paste should be able to pull away the sides of the mixing bowl.
Stir in coconut until it is evenly incorporated and a cookie dough forms.
Using a 1.5 tbsp cookie scoop, scoop out dough balls and place onto the cookie sheet, spacing the balls about 1 inch apart. Press down on each dough ball until it forms a round disk. Cookies will not change shape so shape them as you would like your final cookies to be.
Place cookies in fridge for about 30 minutes to 1 hour to set. The cookies will not change much during refrigeration. They will only become firm enough to hold without the cookies losing their form. Store uneaten cookies in the fridge until ready to consume.
Notes
Mash bananas before measuring out the 4 tbsp. You want to mash until it has the texture of mashed potatoes. I like using a whisk to mash. You should only need 1 large banana (and will have some leftover).
Make sure to use natural peanut butter. There should only be peanuts and salt in the ingredient list and no added oils. See post for potential substitutions.
If you make these cookies with unsweetened shredded coconut, they will not be very sweet but make a healthy treat. If you prefer something sweeter, use sweetened shredded coconut. Alternatively, you can also mix in 1 tbsp of maple syrup into the dough for sweeter cookies.
