- 1 cup creamy peanut butter: Provides rich, nutty flavor and creamy texture throughout each cookie.
- 1 cup rolled oats: Adds hearty chewiness and structure, keeping the cookies tender but firm.
- 1/4 cup brown sugar: Brings caramel warmth and a subtle sweetness that complements the bananas.
- 1 teaspoon vanilla extract: Infuses a fragrant sweetness and depth to balance flavors.

How To Make Peanut Butter Banana Cookies
Baking these cookies is a breeze! You’ll mix, bake, and enjoy gooey, chewy treats in just a few simple steps. By following these instructions, you’ll harness the natural sweetness of bananas and the creamy richness of peanut butter, combining them with oats and warm spices for cookies that feel homemade and wholesome every single time.
1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking and ensure even baking.
2. In a large bowl, mash the ripe bananas with a fork or potato masher until completely smooth and lump-free.
3. Add the creamy peanut butter, brown sugar, and vanilla extract to the mashed bananas, then mix vigorously until all ingredients are well combined and silky.
4. Sprinkle the baking soda and salt into the bowl, then stir gently to distribute those leavening and flavor-balancing agents evenly.
5. Fold in the rolled oats, using a spatula to ensure they’re evenly distributed throughout the batter without overworking the dough.
6. Scoop about 1 tablespoon of dough per cookie onto the prepared baking sheet, spacing them about 2 inches apart. Gently flatten each mound with the back of a spoon for an even shape.
7. Bake in the preheated oven for 10 to 12 minutes, or until the cookie edges turn a light golden color and the centers are set.
8. Allow the cookies to cool on the baking sheet for 5 minutes before carefully transferring them to a wire rack to cool completely.

Tips For Perfect Peanut Butter Banana Cookies
These cookies are forgiving, but a few insider tricks will have you baking like a pro in no time! With just a handful of pantry staples, you can adjust sweetness, texture, and storage to suit your tastes and schedule. Here’s how to make each batch even better:
- The brown sugar adds a hint of caramel flavor but can be omitted for a lower-sugar cookie.

How To Store It
Keeping your Peanut Butter Banana Cookies fresh is a cinch. Whether you’re planning to snack over a few days or stash extras in the freezer, storing them properly ensures they stay soft and flavorful.

- Freeze cookies in a sealed freezer bag or container, layering parchment paper between batches to prevent sticking; they’ll keep perfectly for up to 1 month.
Frequently Asked Questions
Got questions? You’re not alone—here are answers to your most common cookie curiosities:
- How long does it take to prepare and bake these Peanut Butter Banana Cookies?
The total time is about 25 minutes. You’ll need 5 minutes to mash the bananas and mix in peanut butter, sugar, vanilla, baking soda, salt, and oats. Scooping and flattening take another 5 minutes. Baking requires 10 to 12 minutes, plus a 5-minute rest on the baking sheet before cooling completely on a wire rack.
- Can I use overripe or frozen bananas for this recipe?
Yes. Overripe bananas (with brown spots) work well because they’re naturally sweeter and easier to mash. If using frozen bananas, thaw them fully in the microwave or at room temperature, then drain any excess liquid before mashing to prevent soggy dough.
- What can I substitute if I don’t have creamy peanut butter?
You can swap creamy peanut butter for crunchy peanut butter for extra texture or use almond butter or sunflower seed butter if you need a peanut-free option. Note that nut or seed butters with higher oil content may require an extra tablespoon of oats to balance moisture.
- How should I store these cookies, and how long will they stay fresh?
Once completely cooled, store the cookies in an airtight container at room temperature for up to 3 days. To extend shelf life, layer them between parchment paper and freeze in a sealed freezer bag for up to 1 month. Thaw overnight at room temperature before serving.
- Can I make the cookies vegan or reduce the sugar further?
The recipe is already vegan since it contains no eggs or dairy. To reduce sugar, omit the brown sugar entirely; the bananas add natural sweetness. You can also stir in a tablespoon of maple syrup or agave if you prefer a touch more sweetness without refined sugar.
- My cookies spread too much or came out too dense—how can I fix that?
If they spread too much, chill the dough for 10–15 minutes before baking and flatten slightly less. For a lighter texture, use old-fashioned rolled oats rather than quick oats and ensure your baking soda is fresh so the cookies rise properly.
- How can I customize the flavor or add mix-ins?
Fold in up to 1/4 cup of mix-ins such as chocolate chips, chopped nuts, dried fruit, or shredded coconut after adding the oats. You can also sprinkle a pinch of cinnamon or nutmeg into the batter for warm spice notes, or drizzle melted dark chocolate over cooled cookies for an indulgent finish.
