Protein Cookies with Banana, Peanut Butter, and Oats Recipe
Introduction
These protein cookies combine the natural sweetness of ripe bananas with creamy peanut butter and protein powder for a nutritious, satisfying snack. With just four ingredients and simple preparation, they’re perfect for a quick boost after a workout or a healthy treat anytime.

Ingredients
- 2 large ripe bananas (approx. 225g)
- 1 cup natural peanut butter (250g)
- 1/2 cup rolled oats (45g)
- 2 scoops whey or casein protein powder (60g)
Instructions
- Step 1: Preheat your oven to 350°F (180°C). In a large bowl, mash the bananas until they reach a liquid, soup-like consistency with no visible lumps.
- Step 2: Stir in the natural peanut butter until the mixture is a uniform, mahogany-colored paste.
- Step 3: Fold in the protein powder and rolled oats. Use a spatula to press the dough against the sides of the bowl to eliminate any pockets of dry ingredients.
- Step 4: Scoop tablespoon-sized mounds onto a baking sheet lined with parchment paper.
- Step 5: Use a fork to press a cross-hatch pattern into the top of each cookie to increase surface area for browning.
- Step 6: Bake for 12 minutes until the bottoms are deeply golden and the tops feel dry to the touch.
- Step 7: Let the cookies cool on the baking sheet for at least 10 minutes to allow the proteins to firm up before moving.
Tips & Variations
- For extra flavor, add a pinch of cinnamon or vanilla extract to the dough before baking.
- Substitute peanut butter with almond or cashew butter for a different nutty taste.
- Use gluten-free oats if you require a gluten-free option.
- Mix in chocolate chips or chopped nuts for added texture.
Storage
Store the cooled cookies in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week or freeze for up to 3 months. Reheat briefly in the microwave or enjoy them cold.

Ingredients

- 1 cup Natural Peanut Butter (250g)
- 1/2 cup Rolled Oats (45g)
- 2 Scoops Whey or Casein Protein Powder (60g)
Instructions
- Preheat Oven: Preheat your oven to 350°F (180°C) to prepare for baking the cookies.
- Mash Bananas: In a large bowl, mash the ripe bananas until they reach a completely smooth, liquid, soup-like consistency with no lumps remaining.
- Add Peanut Butter: Stir in the natural peanut butter until the mixture becomes a uniform, mahogany-colored paste, ensuring even blending.
- Incorporate Protein Powder and Oats: Fold in the protein powder and rolled oats using a spatula, pressing the dough against the bowl sides to eliminate any dry powder pockets for an even dough consistency.
- Form Cookies: Scoop tablespoon-sized mounds of the dough onto a baking sheet lined with parchment paper, spacing them slightly apart.
- Shape and Texture: Use a fork to press a cross-hatch pattern onto the top of each cookie, increasing the surface area to enhance browning during baking.
- Bake: Bake the cookies in the preheated oven for 12 minutes, until the bottoms turn a deep golden color and the tops feel dry to the touch.
- Cool: Allow the cookies to cool on the baking tray for at least 10 minutes. This cooling step helps the proteins to set and firm up the cookies before removing them.
Notes
- You can substitute whey or casein protein powder with a plant-based protein powder to make the recipe vegan-friendly, but this may affect texture.
- For added sweetness, you may drizzle a small amount of honey or maple syrup, though the bananas provide natural sweetness.
- Make sure bananas are very ripe to ensure proper sweetness and moisture for the cookies.
- These cookies are best stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
- Feel free to add mix-ins like chocolate chips or chopped nuts if desired.
