Step‑by‑Step Instructions for Peanut Butter Banana Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C) to create the perfect baking environment for your Peanut Butter Banana Cookies. While the oven warms up, line a baking sheet with parchment paper, ensuring it’s ready for the cookie dough. This will help prevent sticking and promote even baking.
Step 2: Cream the Butters and Sugars
In a mixing bowl, cream together ½ cup softened unsalted butter and 1 cup creamy peanut butter until the mixture is smooth and fluffy, about 2-3 minutes. Gradually add ½ cup white sugar and ½ cup brown sugar, continuing to mix until everything is well combined and light in color. This step is crucial for getting the right texture in your cookies.
Step 3: Incorporate the Eggs and Vanilla
Next, beat in 2 large eggs one at a time, waiting for each to fully incorporate before adding the next. Then, mix in 1 teaspoon vanilla extract, blending until the batter is smooth and creamy. This will infuse your cookies with delightful flavor and help bind all the ingredients together.
Step 4: Mix the Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 2 cups of rolled oats, 1 teaspoon baking soda, and ½ teaspoon salt. Gradually add this dry mixture to your wet ingredients, stirring just until combined. Be careful not to over-mix; you want the texture to remain tender for your Peanut Butter Banana Cookies.
Step 5: Add Bananas and Chocolate Chips
Once the dough is combined, gently fold in 3 mashed overripe bananas and 1 cup of semisweet chocolate chips. Mix until the ingredients are evenly distributed throughout the dough, allowing the natural sweetness of the bananas and the indulgence of the chocolate chips to shine through in your final cookies.
Step 6: Scoop the Dough
Using a large cookie scoop or spoon, drop rounded tablespoons of cookie dough onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading. The dough should look plush and inviting, making the anticipation of baking your Peanut Butter Banana Cookies all the more exciting.
Step 7: Bake the Cookies
Place the baking sheet in your preheated oven and bake the cookies for about 12 minutes, or until the edges are lightly browned and the centers appear set. Keep an eye on them, as overbaking will result in a less chewy texture.
Step 8: Cool the Cookies
Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 5 minutes before transferring them to a wire rack. This allows them to firm up slightly while retaining a soft and chewy center, making your Peanut Butter Banana Cookies even more delightful!

Peanut Butter Banana Cookies Recipe FAQs
What type of bananas should I use for the best flavor?
Absolutely! For the best flavor, it’s ideal to use overripe bananas that have spots or are even a bit mushy. Their natural sweetness enhances the taste of your Peanut Butter Banana Cookies and adds extra moisture, making them deliciously chewy.
How should I store the Peanut Butter Banana Cookies?
To keep your cookies fresh and soft, store them in an airtight container at room temperature for up to 1 week. If you’re in a cooler climate or prefer them chilled, they can last about 10 days in the fridge, but remember to keep them covered tightly to prevent them from drying out.
Can I freeze Peanut Butter Banana Cookies?
Yes, you can easily freeze your cookies for up to 3 months! Allow the cookies to cool completely, then place them in a single layer on a baking sheet and freeze for about 1-2 hours. Once frozen, transfer them into an airtight container or freezer bag, separating layers with parchment paper to prevent sticking. When you’re ready to enjoy, simply thaw them at room temperature or reheat them in the oven!
I want to make a healthier version; can I substitute the sugars?
Very! You can substitute white sugar with coconut sugar for a lower glycemic index, which works wonderfully without sacrificing sweetness. Similarly, if you want to reduce sugar intake, consider using mashed bananas to add extra sweetness and moisture to your Peanut Butter Banana Cookies, and omit or decrease the sugars used.
What if my cookies come out too dry?
If your cookies turn out dry, it might be due to overbaking, so always watch the timer closely and remove them when the edges are just lightly browned. Additionally, using overripe bananas is essential; they add moisture. For a more forgiving texture, you can add a little more butter or peanut butter to the dough next time. Don’t hesitate to enjoy these cookies warm from the oven for that extra chewy bite!
Are these cookies safe for kids with nut allergies?
If you’re preparing these Peanut Butter Banana Cookies for someone with nut allergies, it’s crucial to avoid peanut butter entirely. You can substitute it with sunbutter (sunflower seed butter) or a nut-free alternative that fits your dietary needs. Just ensure to check ingredient labels for cross-contamination, and always consult with the individual if unsure.
