Why This Recipe Works

When geriatric bananas begin to emerge on my counter, there are a few recipes that immediately come to mind. My favorite banana bars, banana bread and these peanut butter banana cookies.

Here are a few reasons why these three-ingredient peanut butter cookies will change your life:

• This easy recipe is made using only 3 ingredients and done in 20 minutes. Need I say more?
• If you’re looking for delicious flourless peanut butter cookies, you’ve come to the right spot.
• These are the easiest cookies on the block.
• This is a healthy cookie that the whole family will love and that will make your taste buds sing.
• These are the best peanut butter cookies for your cookie jar, providing a great option if you’re looking for a rich peanut butter flavor and chewy cookies.

Recipe Ingredients

Bananas – Ripe bananas work best for this recipe. Simply mash them with fork tines.

Oats – Old-fashioned oats work better than quick oats. This ingredient acts as a flour replacement, making it possible to create a flour free peanut butter cookie (not even almond flour is needed!).

Peanut Butter – Creamy peanut butter works great, but for an added crunch use crunchy peanut butter instead.
For an even healthier cookie, use natural peanut butter, unsalted peanut butter, almond butter, sunflower seed butter or cashew butter.

Peanut Butter Cookie Mix Ins

If you want more than a 3-ingredient peanut butter cookie recipe, add some of these options to the batter. Do not exceed more than 1/2 cup of the following for best results:

• Regular or mini chocolate chips
• Chopped almonds or pecans
• Raisins, dried blueberries or dried cranberries
• Dark chocolate chunks

How To Make Peanut Butter Cookies Without Eggs (+ Only 3 Ingredients!)

These 3-ingredient peanut butter cookies could not be any easier! There is nothing complicated about them. No electric mixer, no flour, no leavening agent, no added oil, no softening butter or bringing eggs to room temperature.

Step 1

Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper and set aside. In a large mixing bowl, combine 2 ripe mashed bananas, 1 cup oats, 1 cup creamy peanut butter and 1 cup semi-sweet chocolate chips (if using).

Stir until combined.

Step 2

Drop 1-inch cookie dough balls onto the prepared baking sheet. Press down slightly on each ball of dough either with your fingers or the back of a fork.

Bake cookies in the preheated oven for 15 minutes, or until golden brown around the edges.

Let the cookies cool completely on a wire rack. Or not. Enjoy!

Recipe Notes

• A teaspoon of vanilla extract would be a delicious addition.
• 1/2 teaspoon of sea salt would add immensely to the flavor, as well!
• A tablespoon or two of maple syrup would add an extra unique flavor.
• A few tablespoons of brown sugar would provide extra sweetness and be extra satisfying for your sweet tooth.
• Use a medium cookie scoop for consistently sized cookies.
• These cookies are gluten free, but be sure to read the label on your oats to make sure they were not packaged in a facility that contains wheat.

How To Store Cookies

These eggless peanut butter cookies should be kept in an airtight container in the fridge for 3-5 days. They can also be frozen for 2 to 3 months in a freezer bag or airtight containers.

Allow them to thaw completely before diving in, or place them in the microwave for 10 seconds if you can’t wait that long!

How To Store Bananas

Store bananas in their bunches on the counter or hanging from a banana tree. Keeping them at room temperature is optimal when they are not yet past their prime.

Some grocery stores will do this for you but to extend the shelf life, wrap the stems in plastic wrap.

Once they start to show signs of ripeness (brown or even black spots), throw them into the fridge if you know you’ll be using them in a recipe in the next few days.

If you don’t have a plan in the near future for overly ripe bananas, put them in the freezer instead.

Before you freeze ripe bananas, it is ideal to remove them from the peel first. It is also ok to just toss the entire banana in the freezer if you don’t want to mess with a peel.

When you are ready to use them in a recipe, allow them to thaw completely before mashing and adding them to your next batch of baked goods!
