This Protein Cookies Recipe is easy to make in one bowl with only 5 ingredients. They are soft, chewy, packed with 6 grams of protein and have no added sugar.
Preheat oven to 350 degrees F. Line large baking sheet with unbleached parchment paper or silicone baking mat, and spray with cooking spray.
In a medium bowl, mash bananas with a fork. Add whey protein powder, oats and peanut butter. Stir well to combine, batter's consistency will be runny. Add chocolate chips and give a few more stirs.
Spoon mixture onto prepared baking sheet (cookies don't spread, so shape them now) and bake for 12-14 minutes (depending on size).
Cool on a cooling rack for 5 minutes.

Notes
Store: Refrigerate in an airtight container for up to 1 week.
Freeze: For up to 1 month. The best way to defrost protein cookies is in a microwave. That way the moisture and softness is restored.
Flavored protein powders: You can use vanilla whey, just make sure you buy unsweetened one.
Can I use plant-based protein powder? No. It contains very absorbent ingredients like peas, rice, which yields dry cookies. For that reason, I don't recommend the substitution.
Can I use previously frozen bananas? Yes. Just make sure to thaw them before using.
Can I use quick oats? You can technically, however due to them being more finely milled, they tend to dry out the cookies, so I avoid them.
