Ingredients for 1 banana cookie
Just 9 ingredients transform one banana into magical cookies that taste like restaurant magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Banana 🍌 | 1 whole | Spotty yellow with brown speckles |
| Walnuts 🥜 | 1 cup | Chopped, unsalted for best flavor |
| All-Purpose Flour 🌾 | ½ cup | For structure without heaviness |
| Baking Powder 🧂 | ½ tsp | Aluminum-free preferred |
| Ground Cinnamon 🌿 | 1 tsp | Freshly ground for warmth |
| Vanilla Extract 🍯 | ½ tsp | Pure alcohol-free if preferred |
| Sea Salt 🧂 | ¼ tsp | Fine grain for delicate seasoning |
| Unsweetened Applesauce 🍎 | ¼ cup | For moisture without sweetness |
| Dark Brown Sugar 🍚 | ¼ cup | Packed tightly for caramel notes |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For crisp edges and richness |
The banana is your star—pick one with brown speckles (those spots = natural sweetness). Walnuts? Store-bought chopped saves time, but toasting them first (5 minutes at 350°F) takes flavor to another level. I grab mine from the bulk section at Whole Foods—cheaper than pre-packaged and fresher too. The baking powder here is non-negotiable: it’s what gives these cookies their sturdy yet tender texture. Diamond Crystal is my go-to brand, but any aluminum-free kind works. For the cinnamon, Penzeys or the bulk spice aisle at Trader Joe's have the freshest ground options—trust me, it makes a difference.
No walnuts? Pecans or almonds work in a pinch (same amount), but the texture gets slightly softer. Short on applesauce? Mashed avocado (same quantity) adds richness without altering flavor. The olive oil can be swapped for melted coconut oil if you’re avoiding nuts entirely. Subbing brown sugar? White sugar works, but these cookies lose their deep caramel notes. Pro tip: Toast the walnuts—even 3 minutes in a dry pan intensifies their flavor. And if you’re worried about the cookies spreading? Chill the dough for 15 minutes before baking—game changer.
These cookies stay soft for 3-4 days in an airtight container, but honestly? They’re best fresh out of the oven. Freeze extras by flattening them slightly on a tray first, then transferring to a bag—prevents them from turning into hockey pucks. I like to portion the dough into 12 equal balls ahead of time so baking becomes a breeze. Double batch and freeze half: perfect for when banana cravings hit unexpectedly. And if you’re meal prepping? These hold up beautifully—just reheat for 10 seconds in the microwave to revive the crisp edges.

Step-by-step instructions for single-ingredient banana cookies
Here's how to transform one ripe banana into 12 perfect cookies with nutty crunch!
👨🍳 Step 1: Mash the Banana and Mix Wet Ingredients
Start by mashing the 1 whole ripe banana in a medium bowl until completely smooth—no lumps! I like to use a fork for this step, pressing down firmly to break up any stubborn bits. The banana should look like a thick, creamy puree.
Add the 0.25 cup unsweetened applesauce, 0.25 cup dark brown sugar (packed tightly), and 1 tbsp extra-virgin olive oil. Stir everything together until fully combined. The mixture will be thick but spreadable—this is perfect for our cookie dough. The olive oil gives these cookies that beautiful crisp edge while keeping them tender inside.
👨🍳 Step 2: Combine Dry Ingredients and Fold Together
In a separate bowl, whisk together the 0.5 cup all-purpose flour, 0.5 tsp baking powder, 1 tsp ground cinnamon, 0.5 tsp vanilla extract, and 0.25 tsp sea salt. The cinnamon should be freshly ground for that warm, aromatic flavor that makes these cookies special.
Pour the dry ingredients into the wet mixture and gently fold everything together with a silicone spatula. Be careful not to overmix—just combine until no dry spots remain. The dough will be thick and sticky, almost like cookie dough you'd expect from a ripe banana.
👨🍳 Step 3: Fold in Chopped Walnuts for Crunch
Add the 1 cup chopped walnuts to the dough and fold them in gently but thoroughly. You want each spoonful of dough to have a good distribution of those nutty pieces. I like to press the dough together with my fingers to ensure even coating—this is where those delicious crunchy bits will shine in every bite.
Here's the thing—don't worry if the dough looks too thick. It's supposed to be this way! The walnuts will add moisture as they soften slightly during baking, and the applesauce helps keep everything cohesive. If you're concerned, you can chill the dough for 15 minutes to make it easier to handle, but it's not strictly necessary.
🔥 Step 4: Scoop and Bake for Perfect Cookies
Preheat your oven to 350°F and line two baking sheets with parchment paper. Using a 1-tablespoon cookie scoop (or a spoon), portion out the dough onto the prepared sheets, leaving about 2 inches between each scoop. The cookies won't spread much, so you can place them a bit closer than usual.
Bake for 12-14 minutes until the edges are golden brown and the tops look set but still slightly soft in the center. They'll firm up as they cool. Watch them closely after 10 minutes—the olive oil helps create that beautiful crisp edge, but you don't want them to overbrown. When you pull them out, they should still have a slight sheen to the top.
⏰ Step 5: Cool and Enjoy (Or Freeze for Later!)
Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This short rest prevents them from breaking apart when you move them. As they cool, you'll notice the aroma of cinnamon and walnuts filling your kitchen—trust me, it's worth the wait!
These cookies are best enjoyed warm, but they'll keep at room temperature in an airtight container for up to 3 days. For longer storage, freeze them for up to 3 months. When you're ready to eat, just pop them in the oven at 300°F for 3-5 minutes to warm them up and restore that perfect texture.
Pro Tips For Making 1 Banana Cookie
- Mash Bananas First: I learned this the hard way—skipping the mash step means uneven texture. Use a fork to break up the banana completely, then press through a fine-mesh sieve to remove those stubborn skin bits. Your cookies will thank you with a smoother bite.
- Toast Walnuts Before Mixing: My grandmother swore by this, and she was right: toasting walnuts for 5-7 minutes in a dry pan until fragrant adds depth. Let them cool before chopping—hot nuts release oils that make your dough greasy. (Yes, even if you're impatient like me.)
- Chill Dough for 30 Minutes: This isn’t the prettiest method, but it’s the tastiest. The dough will spread less, and the cinnamon flavor mellows into something richer. I skip this when I’m lazy, but the cookies are noticeably better when I don’t—crisp edges, soft centers, no sad flat pancakes.
- Use 1 Extra Teaspoon Cinnamon: The recipe’s amount feels shy. I was skeptical until I tried it—an extra teaspoon (up to 2 if you’re bold) makes the banana flavor sing. Just don’t overmix after adding it, or your cookies turn dense. Stir until just combined.
Perfect pairings for 1 banana cookie
Creamy Coffee Pairing
Warm these cookies with a cup of cold brew coffee or vanilla latte for a cozy contrast. The nutty, caramelized edges of the cookie complement the smooth, slightly bitter notes of coffee perfectly.
I love adding a splash of heavy cream to my coffee to balance the richness of the banana and walnuts. For an extra touch, sprinkle cinnamon sugar on top of the cookies right before serving. ☕
Iced Tea Refreshment
Serve these cookies alongside sweet iced tea (I prefer peach or hibiscus) for a refreshing balance. The tea’s tartness cuts through the cookie’s natural sweetness, while the ice keeps the cookies from getting soggy.
For a festive twist, add a slice of lemon to your glass. The citrus brightens the flavors and makes the cookies taste even more indulgent. 🍹
Chocolate Dipping Sauce
Melt 60g dark chocolate (70% cocoa) with 1 tbsp coconut oil for a quick dipping sauce. The bitterness of the chocolate contrasts beautifully with the cookie’s caramelized edges and creamy banana center.
I like to drizzle a little sea salt on top for a sophisticated finish. This pairing is perfect for dessert nights or when you want to elevate your cookie experience. 🍫
Yogurt Dip Comfort
Warm Greek yogurt with a drizzle of honey and a pinch of cinnamon makes an unexpected but delicious dip for these cookies. The tangy yogurt balances the cookie’s richness, while the honey adds a subtle sweetness.
This combo is especially great for breakfast or an afternoon snack when you need something light yet satisfying. 🥄
Spiced Milk Alternative
Heat 1 cup milk (dairy or almond) with ½ tsp cinnamon, ¼ tsp vanilla extract, and a pinch of nutmeg. The warm spices echo the cookie’s cinnamon flavor while adding depth.
Serve the cookies warm alongside this drink for a comforting, dessert-like experience that feels like a hug in a cup. 🌟
Fruit Salad Contrast
Pair these cookies with a fruit salad featuring berries, kiwi, and mango for a refreshing contrast. The bright, juicy flavors of the fruit balance the cookie’s richness, while the walnuts add a satisfying crunch.
This combo works perfectly for brunch or a light dessert when you want something fresh and balanced. 🍓

Frequently asked questions
Why do I need to use a ripe banana for this recipe?
Ripe bananas with brown speckles are sweeter and creamier, creating a naturally sweet cookie without added sugar. The natural sugars caramelize beautifully during baking, giving these cookies their signature depth of flavor. Overripe bananas (black spots) work too, but they're even sweeter—reduce the brown sugar to 0.125 cup if using them.
Can I make these cookies without walnuts?
Swap walnuts for 1 cup chopped pecans or almonds for a different texture. For nut-free versions, try 1 cup oats or chopped dried fruit like cranberries or apricots. Just note the texture will be softer—these cookies rely on the walnuts for their signature crunch.
How do I prevent the cookies from spreading too much?
Chill the dough for 15 minutes before baking to firm it up. Use a 1-tablespoon scoop and place cookies 2 inches apart on the baking sheet. The olive oil helps create crisp edges, but if they still spread, reduce baking time to 10-12 minutes—they'll firm up as they cool.
Are these cookies gluten-free?
Not as written, but you can easily adapt them! Replace the all-purpose flour with 0.5 cup gluten-free 1:1 baking flour (like Bob's Red Mill) plus 0.25 cup almond flour for structure. Add 0.5 tsp xanthan gum if your blend requires it. The texture will be slightly denser but still delicious.
Can I make these cookies ahead of time?
Yes! These cookies stay fresh for 3-4 days in an airtight container at room temperature. For longer storage, freeze the baked cookies for up to 3 months. To reheat, warm at 300°F for 3-5 minutes to restore crisp edges. The dough itself can be refrigerated for 24 hours—just let it sit at room temp for 10 minutes before scooping.
