Join me as we bake up a batch of these irresistible cookies!
Ingredients
- Ripe Bananas: The riper, the better! Overripe bananas provide natural sweetness and moisture, creating a soft and tender cookie. The enzymes in ripe bananas also help break down starches, contributing to a smoother texture.
- Creamy Peanut Butter: Provides that classic peanut butter flavor and adds richness to the cookies. Opt for natural peanut butter with no added sugar or oils for a healthier option. You can also substitute with other nut butter such as almond or cashew.
- Rolled Oats: Rolled oats (also known as old-fashioned oats) give the cookies a chewy texture and add a boost of fiber. Quick oats can be used in a pinch, but the texture will be slightly different.
- All-Purpose Flour: Provides structure to the cookies. For a gluten-free option, use a gluten-free all-purpose flour blend.
- Baking Soda: A leavening agent that helps the cookies rise and become light and airy.
- Baking Powder: Adds extra lift and contributes to a softer texture.
- Vanilla Extract: Enhances the overall flavor of the cookies.
- Cinnamon: Adds warmth and a touch of spice.
- Salt: Balances the sweetness and enhances the other flavors.
- Chocolate Chips (Optional): For an extra touch of indulgence. Dark chocolate chips are a great option for a slightly healthier treat.

Expert Tips for Perfect Peanut Butter Banana Oatmeal Cookies
Here are a few of my tried-and-true tips for achieving the best possible Peanut Butter Banana Oatmeal Cookies:
- Don’t overmix the batter: Overmixing can lead to tough cookies. Mix the wet and dry ingredients until just combined.
- Use a cookie scoop: This ensures that all the cookies are the same size, which helps them bake evenly.
- Chill the dough (optional): Chilling the dough for 30 minutes can help prevent the cookies from spreading too much during baking.
- Bake until golden brown: The cookies should be golden brown around the edges and slightly soft in the center. They will continue to firm up as they cool.
- Let the cookies cool completely before storing: This prevents them from becoming soggy.
In my testing, I’ve found that using very ripe bananas is key to the best flavor and texture. I often freeze overripe bananas specifically for baking these cookies. Also, don’t be afraid to experiment with different mix-ins! Chopped nuts, dried fruit, or even a sprinkle of sea salt can add a unique twist.
FAQ: Your Peanut Butter Banana Oatmeal Cookie Questions Answered
Can I use quick oats instead of rolled oats?
Yes, you can use quick oats, but the texture of the cookies will be slightly different. They will be a bit softer and less chewy. If you’re using quick oats, you may want to reduce the amount by a tablespoon or two to prevent the cookies from becoming too dry.
Can I freeze these cookies?
Absolutely! These cookies freeze beautifully. Let them cool completely, then store them in an airtight container in the freezer for up to 2 months. Thaw at room temperature before enjoying.
Can I make these cookies vegan?
Yes, you can! Replace the peanut butter with another nut butter or a sunflower seed butter alternative. Since there are no eggs, it’s already mostly vegan friendly.
How do I store these cookies?
Store the cookies in an airtight container at room temperature for up to 3 days. To keep them fresh longer, store them in the refrigerator for up to a week.
Can I add protein powder to these cookies?
Yes, you can add protein powder to these cookies! I recommend using about 1/4 cup of your favorite protein powder. You may need to add a tablespoon or two of milk or water to compensate for the added dryness. Whey or casein protein will make a slightly cakier cookie, while plant-based protein may make the cookie a bit denser.
Are these cookies healthy?
While these cookies contain natural sugars from bananas and may include chocolate chips, they are generally healthier than traditional cookies. They are made with whole grains, healthy fats, and natural sweeteners. Portion control is always important, but these cookies can be a satisfying and guilt-free treat.
What if my cookie dough is too dry?
If your cookie dough seems too dry, add a tablespoon of milk or water at a time until the dough reaches a scoopable consistency. The amount of liquid needed can vary depending on the size of your bananas and the moisture content of your peanut butter.
