Equipment You’ll Need

• Large mixing bowl
• Fork or potato masher
• Spatula
• Baking sheet
• Parchment paper
• Cookie scoop or two spoons

Ingredients

• 2 large, very ripe bananas (the more brown spots, the better)
• 1/2 cup natural, creamy peanut butter (ingredients should be just peanuts and salt)
• 1/4 cup unsweetened cocoa powder
• Optional: 1/2 tsp vanilla extract
• Optional: Pinch of flaky sea salt for topping

Instructions

1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a large mixing bowl, peel the ripe bananas and mash them thoroughly with a fork or potato masher until they are almost liquid with very few lumps.
3. Add the natural peanut butter and unsweetened cocoa powder to the mashed bananas. If using, add the vanilla extract now.
4. Mix with a spatula until all the ingredients are fully combined and a smooth, thick, brownie-like batter forms. The mixture will be sticky.
5. Using a cookie scoop or two spoons, drop rounded tablespoons of the dough onto the prepared baking sheet, about 2 inches apart.
6. These cookies will not spread while baking. Use the back of a spoon or your fingertips (dampened with a little water to prevent sticking) to gently flatten each mound of dough to your desired cookie thickness.
7. Bake for 12-15 minutes. The cookies are done when the tops are set and feel firm to the touch. They will still be soft inside.
8. Remove the baking sheet from the oven and let the cookies cool on the sheet for at least 10 minutes. This is a crucial step as they will be very delicate while hot and need time to firm up.
9. Once firm enough to handle, transfer the cookies to a wire rack to cool completely. If desired, sprinkle with flaky sea salt while they are still slightly warm.

Expert Cooking Tips

• Banana Ripeness is Key: The sweetness of these cookies comes entirely from the bananas. Use bananas that are heavily speckled with brown or even completely brown for the best flavor and sweetness.
• Peanut Butter Matters: Use a natural, drippy peanut butter. Processed peanut butters like Jif or Skippy contain added sugars and oils that will alter the texture and make the cookies greasy.
• Don’t Expect a Snap: The texture of these cookies is soft, moist, and cakey, similar to a fudgy brownie. They are not a crispy or crunchy cookie.
• Cool Completely: Do not skip the cooling period on the baking sheet. They are very fragile when hot and will fall apart if you try to move them too soon.

Substitutions and Variations

For the peanut butter, any other natural nut or seed butter will work well. Try almond butter, cashew butter, or for a nut-free version, sunflower seed butter or tahini. The cocoa powder can be omitted for a 2-ingredient peanut butter banana cookie. Unfortunately, the banana is essential for the structure, moisture, and sweetness of this recipe and does not have a suitable substitute.

Common Mistakes to Avoid

The most common mistake is using underripe, yellow bananas, which results in a bland and starchy cookie. Another frequent error is expecting the cookies to spread in the oven; they must be flattened before baking. Finally, using processed, no-stir peanut butter can lead to an oily final product with an altered texture. Stick to natural nut butters where the oil separates.

Serving Suggestions

These cookies are fantastic on their own as a quick snack. For a more decadent dessert, serve them warm with a scoop of vanilla bean ice cream or a dollop of coconut cream. They can also be crumbled over a yogurt bowl for a healthy breakfast treat or used to make a cookie sandwich with a cream cheese or yogurt filling.

Storage and Reheating Tips

Store the cookies in an airtight container. They can be kept at room temperature for up to 2 days or in the refrigerator for up to a week. Due to the high moisture content from the banana, refrigeration is recommended to maintain freshness and prevent them from becoming overly soft.

Frequently Asked Questions

Can I add mix-ins like chocolate chips or nuts?

Absolutely! This recipe is a great base for additions. Feel free to stir in 1/4 cup of sugar-free chocolate chips, chopped walnuts, pecans, or even shredded coconut for added texture and flavor.

Are these cookies keto-friendly?

While these cookies are low in carbohydrates compared to traditional cookies, they are not strictly keto-friendly because bananas are high in natural sugars and carbs. They are better suited for a paleo or generally health-conscious diet.

Can I use powdered peanut butter?

You can, but the ratios will change. You would need to reconstitute the powdered peanut butter with water first to achieve a creamy, natural peanut butter consistency before adding it to the mashed banana.
