Finding a cookie recipe that’s both kid-friendly and made with ingredients you actually feel good about can be tough. Most cookie recipes call for loads of butter and sugar, which aren’t exactly ideal when you’re trying to keep things a bit healthier for your family, and it gets even trickier when you’re working with dietary restrictions or picky eaters.
Thankfully, these peanut butter banana cookies solve all those problems: they’re naturally sweetened with ripe bananas, simple to whip up with just six ingredients, and easy to customize based on what’s already sitting in your pantry.
Why You’ll Love These Peanut Butter Banana Cookies
- Only 4 ingredients – You probably have everything you need in your pantry right now, making these cookies super convenient to whip up whenever a craving hits.
- Naturally sweetened – The ripe bananas provide all the sweetness you need, so there’s no added sugar required.
- Ready in under 30 minutes – From mixing bowl to cooling rack, these cookies come together fast, perfect for last-minute snacks or desserts.
- Healthy treat – Made with wholesome oats, fruit, and peanut butter, these cookies make a great breakfast option or post-workout snack that won’t leave you feeling guilty.
What Kind of Peanut Butter Should I Use?
For these cookies, you’ll want to stick with regular creamy peanut butter rather than the natural kind that separates. The natural varieties with the oil on top can make your cookies too greasy and they won’t hold together as well. If you’re a chunky peanut butter fan, that works too and will add some extra texture to your cookies. Just make sure whatever peanut butter you use is at room temperature so it mixes easily with the mashed bananas.
Options for Substitutions
These simple cookies are easy to customize based on what you have in your pantry:
- Quick oats: You can use old-fashioned rolled oats instead of quick oats. Just pulse them a few times in a food processor or blender to break them down slightly, so your cookies hold together better.
- Peanut butter: Any nut or seed butter works here – try almond butter, cashew butter, or sunflower seed butter if you have a peanut allergy. Just make sure it’s the creamy kind, not the natural separated type, or your cookies might turn out too crumbly.
- Bananas: The bananas are really what holds these cookies together, so I wouldn’t recommend substituting them. Make sure they’re nice and ripe with brown spots for the best sweetness and binding power.
- Chocolate chips: Feel free to swap these out for raisins, dried cranberries, chopped nuts, or even butterscotch chips. You could also leave them out completely for a plain version.
Watch Out for These Mistakes While Baking
The biggest mistake you can make with these cookies is using bananas that aren’t ripe enough – look for bananas with brown spots all over the peel, as they’re sweeter and mash more easily into a smooth consistency.
Another common error is skipping the flattening step, which leaves you with thick, undercooked cookies that don’t hold together well, so press each ball down to about 1/2 inch thick before baking.
Since these cookies don’t contain flour or eggs, they’re more delicate than regular cookies and can fall apart if you try to move them too soon – let them cool on the baking sheet for at least 5 minutes before transferring to a cooling rack.
Finally, keep a close eye on them during the last few minutes of baking, as the thin edges can go from golden to burnt quickly, and remember that they’ll firm up as they cool even if they seem soft when you first take them out.
What to Serve With Peanut Butter Banana Cookies?
These cookies are perfect for an afternoon snack with a cold glass of milk or your favorite coffee. I love packing them in lunchboxes alongside some apple slices and cheese cubes for a balanced treat that keeps everyone happy. They also make a great breakfast on busy mornings when you pair them with Greek yogurt and fresh berries. Since they’re naturally sweet from the bananas, they go really well with something tangy like a fruit smoothie or even just a cup of hot tea.
Storage Instructions
Store: Keep these cookies in an airtight container at room temperature for up to 3 days, or in the fridge for about a week. They’ll stay soft and chewy, making them perfect for grabbing as a quick breakfast or snack throughout the week.
Freeze: These cookies freeze really well for up to 3 months. Just layer them between parchment paper in a freezer-safe container so they don’t stick together. You can also freeze the dough in scoops on a baking sheet, then transfer to a bag once frozen, so you can bake fresh cookies whenever you want.
Thaw: Let frozen cookies sit at room temperature for about 20 minutes, or pop them in the microwave for 10-15 seconds if you want them warm and gooey. They taste amazing straight from the freezer too if you like a firmer texture!

- Calories: 1550-1700
- Protein: 35-40 g
- Fat: 60-70 g
- Carbohydrates: 215-230 g
Ingredients
- 2 1/4 cups quick oats (I always use Quaker for the best consistency)
- 1 1/4 cups mashed bananas (very ripe with brown spots for natural sweetness)
- 1/2 cup peanut butter (I prefer Jif creamy for a smoother dough)
- 1/3 cup chocolate chips
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
Step 1: Prepare the Oven and Mise en Place
- Parchment paper for baking sheet
Preheat your oven to 350°F and line a baking sheet with parchment paper.
While the oven heats, gather all your ingredients and have them ready to go—this quick prep ensures you can mix the dough efficiently once everything is measured out.
Step 2: Combine All Ingredients into Cookie Dough
- 1 1/4 cups mashed bananas
- 1/2 cup peanut butter
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 2 1/4 cups quick oats
- 1/3 cup chocolate chips
In a large mixing bowl, combine the mashed bananas, peanut butter, ground cinnamon, and salt.
Mix until well combined, then fold in the quick oats until fully incorporated—the dough will be thick and slightly moist.
Finally, gently fold in the chocolate chips, being careful not to crush them.
I always recommend using very ripe bananas with brown spots here, as they provide natural sweetness and moisture without needing added sugar.
Step 3: Shape and Arrange Cookies on Baking Sheet
- Cookie dough from Step 2
Using a 1.5 tablespoon cookie scoop or two spoons, portion the dough into evenly-sized balls and place them about 2 inches apart on the prepared baking sheet.
Gently flatten each cookie to about 1/4-inch thickness using the back of a spoon or your palm—this helps them bake more evenly and develop better texture.
Step 4: Bake Until Set and Golden
- Shaped cookies from Step 3
Place the baking sheet in the preheated 350°F oven and bake for 8-10 minutes, until the edges are lightly golden and the centers are just set.
I like to check them around the 8-minute mark since oven temperatures vary—they should still feel slightly soft in the center when you remove them, as they’ll continue to firm up as they cool.
Step 5: Cool and Serve
- Baked cookies from Step 4
Remove the baking sheet from the oven and let the cookies cool on the sheet for 2-3 minutes to firm up slightly, then serve warm or transfer to a cooling rack for complete cooling.
These cookies are best enjoyed fresh and warm, when the peanut butter and chocolate are still slightly soft.
