How to Make Banana Oat Cookies

Preheat oven: Preheat your oven to 350°F and line a baking sheet with parchment paper. This ensures even baking and easy cleanup, giving cookies golden bottoms.
Mash bananas: Peel and mash 2–3 overripe bananas in a medium bowl using a fork or potato masher until mostly smooth, leaving small chunks for chewy texture.
Mix dry ingredients: Combine 1½ cups rolled oats, 1 teaspoon baking powder, 1 teaspoon ground cinnamon, and a pinch of salt in a bowl. Stir until all dry ingredients are well blended.
Combine: Pour mashed bananas and 1 teaspoon vanilla extract into the oat mixture. Fold gently with a spatula until the batter is evenly combined and slightly sticky, creating dough that’s easy to spoon.

Optional Add-Ins:

Fold in: Your choice of ½ cup chocolate chips, chopped nuts, or dried fruit; stir until add-ins are evenly distributed throughout the dough.
Scoop dough: Use a tablespoon to drop mounds onto the prepared sheet, spacing cookies about 2 inches apart for even spreading and uniform shapes.
Bake: Bake at 350°F for 12–15 minutes, rotating the sheet halfway through. Look for golden edges and centers that are set but still soft.
Cool: Let cookies rest on the sheet for 5 minutes to set, then transfer to a wire rack to cool completely before enjoying.

Optional: Sprinkle a pinch of sea salt over warm cookies for a gourmet twist.

Expert Tips for Banana Oat Cookies

Use ripe bananas: Overripe bananas are key for natural sweetness and moisture, preventing bland or dry cookies.
Don’t overmix: Fold ingredients gently to keep the cookies tender and chewy, avoiding tough or dense results.

Best Banana Oat Cookies Recipe FAQs

How ripe should the bananas be for the best banana oat cookies?
For the sweetest and most flavorful cookies, use overripe bananas with dark spots all over the peel. These bananas are soft, naturally sweeter, and add wonderful moisture to the dough. Avoid underripe bananas as they may result in a less sweet and drier cookie.

What’s the best way to store banana oat cookies, and how long do they last?
Store your banana oat cookies in an airtight container at room temperature to keep them soft and chewy for up to 3 days. If you prefer a firmer texture, refrigerate them in an airtight container, which extends their freshness up to a week. Always let them cool completely before storing to prevent moisture buildup.

Can I freeze banana oat cookies, and how do I thaw them properly?
Absolutely! Freeze your cookies by first placing them in a single layer on a baking sheet to avoid sticking, then transfer them to a freezer-safe bag or container. They keep perfectly for up to 3 months. When ready to enjoy, simply thaw at room temperature or heat briefly in the microwave for about 10–15 seconds to revive their chewy softness.

My cookies turned out crumbly instead of chewy—what went wrong?
This is a common issue and usually means the banana-to-oat ratio was off or the oats were overmeasured. Be sure to use enough ripe bananas for moisture, and measure oats accurately—not packed or heaping cups. Also, avoid overbaking; take the cookies out when the edges are golden but centers still look a little soft to retain chewiness.

Are banana oat cookies safe for my pets or people with allergies?
These cookies generally contain simple ingredients safe for humans but might not be suitable for pets because of ingredients like chocolate chips or nuts. For allergy concerns, substitute add-ins like nuts with seeds or dried fruit and always check for cross-contamination if gluten sensitivity is a concern (use certified gluten-free oats). I often recommend customizing the mix to your family’s needs!
