Ingredient Highlights & Substitutions
Essential Ingredients
Ripe Bananas: The browner, the better. Overripe bananas are sweeter and mash easier, acting as the wet base for the dough.
Rolled Oats: Old-fashioned rolled oats provide the best chewy texture. They are a great source of fiber.
Peanut Butter: Use a creamy, natural peanut butter. The oils help bind the cookies and keep them moist.
Protein Powder: Vanilla or chocolate whey protein works best here. It adds the protein punch and contributes to the flavor profile.
Smart Substitutions
If you are allergic to peanuts, almond butter or sunflower seed butter are excellent swaps that won’t compromise the texture. For a vegan version, ensure your protein powder is plant-based (like pea or soy protein). If you don’t have bananas, pumpkin puree can be used, though you may need to add a splash of maple syrup for sweetness. Quick oats can be used in a pinch, but the cookies will be softer and less textured than with rolled oats.
Step-by-Step Instructions
Prep Phase
Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat. Peel your ripe bananas and place them in a large mixing bowl. Using a fork or a potato masher, mash the bananas thoroughly until they are almost liquid with only small lumps remaining. Measure out your oats, peanut butter, and protein powder so they are ready to dump in.
Cooking Phase
Add the peanut butter to the mashed bananas and mix until combined. Stir in the protein powder until dissolved and smooth. Finally, fold in the oats until they are fully coated in the wet mixture. If the dough seems too wet, let it sit for 5 minutes so the oats can absorb some moisture. Scoop about 2 tablespoons of dough per cookie onto the baking sheet. Flatten them gently with the back of a spoon or fork, as they won’t spread much while baking. Bake for 12-15 minutes until the edges are golden and the cookies feel set. Let them cool on the pan for 10 minutes before moving to a wire rack.
Pro Tips for Perfect Results
Technique Secrets
The consistency of your cookie dough relies heavily on the size of your bananas and the type of protein powder used. Whey protein tends to be stickier, while casein or plant-based proteins are more absorbent. If your dough is too crumbly, add a splash of milk or water. If it is too runny, add a tablespoon more oats. Flattening the cookies before baking is crucial because without butter or baking soda, these cookies stay exactly the shape you put them in the oven.
Common Mistakes to Avoid
A common mistake is using under-ripe bananas. Green or yellow bananas lack the necessary sugar content and moisture, leading to bland, dry cookies. Wait for those brown spots! Another mistake is over-baking. Since there are no raw eggs or flour to “cook out,” you only need to bake them until they hold together. Over-baking will result in a rubbery texture due to the protein powder drying out.

Frequently Asked Questions
Q1? Can I use instant oats?
Yes, but the texture will be softer and less chewy. Rolled oats are preferred for structure, but instant oats will work in a pinch.
Q2? How do I store them?
Store these cookies in an airtight container in the refrigerator for up to 1 week. Because of the banana content, they can spoil faster than regular cookies if left out in warm weather.
Q3? Can I freeze them?
Absolutely. Flash freeze them on a tray for an hour, then transfer to a freezer bag. They can be frozen for up to 3 months. Thaw on the counter for 15 minutes before eating.
