This banana walnut chocolate chip cookies recipe delivers the perfect balance of chewy texture, nutty crunch, and gooey chocolate—all in one bite. 🌟 The secret lies in ripe bananas that add natural sweetness and moisture, while toasted walnuts provide that satisfying crunch.
I developed this recipe after years of testing, ensuring every cookie has a tender center and crisp edges without drying out.
What makes these cookies stand out is the combination of ingredients working together harmoniously. The bananas bind the dough naturally, eliminating the need for extra eggs, while the walnuts add richness and texture that pairs beautifully with the chocolate chips.
The result is a cookie that's slightly denser than traditional chocolate chip but still light enough to enjoy with a glass of milk.
Baking at 350°F for about 12 minutes ensures golden edges and a soft center, with walnuts that stay crisp. The chocolate chips melt just enough to create pockets of gooey goodness in every bite.
This recipe is foolproof, whether you're making a batch for a holiday treat or a quick afternoon snack.
For added versatility, you can easily swap out the chocolate chips for white chocolate or dark chocolate chunks, or even add a sprinkle of sea salt for a gourmet twist.
The dough can also be made ahead and chilled for up to 48 hours, making it perfect for meal prep or last-minute baking.
Ingredients for banana walnut chocolate chip cookies
Ripe bananas, toasted walnuts, and chocolate chips transform simple pantry staples into irresistible cookies.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Spot blackened for sweetness |
| All-Purpose Flour 🌾 | 2 ½ cups | Sifted for light texture |
| Walnuts 🥜 | 1 ½ cups | Toasted and chopped |
| Chocolate Chips 🍫 | 1 ½ cups | Semi-sweet preferred |
| Granulated Sugar 🍚 | ¾ cup | Light brown sugar works too |
| Baking Soda 🧂 | 1 tsp | Ensures proper rise |
| Ground Cinnamon 🌿 | 1 ½ tsp | Warmth without overpowering |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🥛 | 1 tsp | Pure extract for flavor |
| Unsalted Butter 🧈 | ½ cup | Room temperature for mixing |
| Flaky Sea Salt 🧂 | 1 tsp | For finishing cookies |
The bananas are non-negotiable—spot the blackest ones for maximum sweetness and moisture. Trader Joe's usually has perfect ones, or check the back of the produce section at Whole Foods. Walnuts should be toasted until fragrant (about 8 minutes at 350°F) to deepen their flavor. For chocolate chips, Ghirardelli semi-sweet are my go-to, but any quality brand works. The butter needs to be room temperature—press a finger in it; if it springs back, it's ready. Too cold? Microwave 20 seconds to soften.
No ripe bananas? Use 1/2 cup unsweetened applesauce plus 1/4 cup extra sugar—it mimics the moisture. Swap walnuts for pecans or almonds if you prefer, but toast them first. Chocolate chips can be white chocolate or dark chocolate chunks—just adjust baking time slightly. For a gourmet twist, add 1/4 tsp sea salt to the dough or sprinkle flaky salt on top after baking. The cinnamon can be omitted if you dislike its flavor, but I find it enhances the walnut sweetness beautifully.
Dough keeps 48 hours in the fridge, wrapped tightly in plastic. For best texture, bake immediately after mixing. Store baked cookies in an airtight container at room temperature for up to 5 days or freeze for 3 months. Reheat in a 300°F oven for 2-3 minutes to restore crispness. These cookies reheat surprisingly well—perfect for a quick snack when you need a taste of homemade.
Why You'll Love This Recipe

Step-by-step instructions for banana walnut chocolate chip cookies
Here's how to craft chewy, nutty-sweet cookies with perfect texture every time.
👨🍳 Step 1: Mash the Bananas and Mix Wet Ingredients
In a medium bowl, mash the 3 medium ripe bananas with a fork until completely smooth—no lumps allowed. The bananas should be spotty blackened for that perfect sweetness. Add the 0.5 cup unsalted butter (room temperature) and mix until fully combined. Then stir in the 0.75 cup granulated sugar, 1 tsp vanilla extract, and 1.5 tsp ground cinnamon until everything is evenly incorporated.
This is where the magic starts—the banana's natural sweetness and moisture create the chewy texture these cookies are famous for. If your butter isn't quite room temperature, let it sit at room temperature for another 10 minutes before mixing. You'll know it's ready when it leaves a slight indent when pressed with your finger.
👨🍳 Step 2: Combine Dry Ingredients and Fold in Mix-Ins
In a separate large bowl, whisk together the 2.5 cups all-purpose flour, 1 tsp baking soda, and 0.5 tsp salt. Sift the flour mixture once to aerate it—this ensures a light, tender cookie. Gradually pour the dry ingredients into the wet mixture and stir just until combined. You want to avoid overmixing, so stop stirring as soon as the flour disappears.
Next, fold in the 1.5 cups walnuts (pre-toasted and chopped) and 1.5 cups chocolate chips using a silicone spatula. Make sure the nuts and chocolate are evenly distributed throughout the dough. I like to press down gently on the dough with the spatula to ensure the mix-ins are fully incorporated—no one wants a surprise bite of plain dough!
⏰ Step 3: Chill the Dough for Perfect Texture
Cover the bowl with plastic wrap and refrigerate the dough for at least 30 minutes—I prefer 1 hour if you have time. This chilling step is crucial for two reasons: it firms up the butter so the cookies hold their shape, and it allows the flour to fully hydrate, resulting in a tender crumb. Don't skip this step, even if you're eager to bake. Trust me, the wait is worth it.
While the dough chills, preheat your oven to 350°F and line two baking sheets with parchment paper. The dough will be soft and sticky when you take it out of the fridge, but that's exactly how it should be. If the dough feels too soft to handle, give it another 15 minutes in the fridge—it needs to be firm enough to scoop without sticking to your hands.
🔥 Step 4: Bake to Golden Perfection
Using a cookie scoop or tablespoon, portion the dough into 1.5-tablespoon-sized balls (about 1.5 ounces each) and place them 2 inches apart on the prepared baking sheets. These cookies spread slightly, so giving them space ensures they don't merge together. Sprinkle each cookie with a pinch of flaky sea salt right before baking—this adds a delightful contrast to the sweetness.
Bake for 10-12 minutes until the edges are golden brown and the centers still look slightly soft. They'll continue cooking on the hot baking sheet after you remove them from the oven, so don't overbake. The cookies should pull away from the edges of the parchment paper slightly, but the centers should remain slightly underdone for that perfect chewy texture.
⏰ Step 5: Cool and Enjoy Warm
Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. This brief resting period helps them set slightly, making them easier to handle. The cookies will firm up as they cool, but they're best enjoyed warm—still soft and gooey inside with that perfect crunch from the walnuts and chocolate chips.
Serve them with a glass of cold milk or a cup of coffee. These cookies are at their peak when they're still slightly warm, with the chocolate chips just starting to melt and the walnuts adding a satisfying crunch. Store any leftovers in an airtight container at room temperature for up to 3 days, though I doubt they'll last that long!
Pro Tips For Making Banana Walnut Chocolate Chip Cookies
- Mash Bananas Until Smooth: I learned this the hard way—lumpy banana dough turns into dense, chewy cookies. Use a fork first to break them up, then switch to a potato masher or wooden spoon for 2-3 minutes until no visible chunks remain. The smoother the mash, the lighter the texture.
- Toast Walnuts First: Skip the raw walnuts—they’ll release bitter oils and make your cookies taste like a sad salad. Lightly toast them in a dry skillet over medium heat for 4-5 minutes, shaking the pan often, until fragrant and golden. Let them cool completely before chopping, or they’ll melt into the dough.
- Chill Dough for 30 Minutes: Yes, even if you’re impatient like me. The banana releases moisture, and skipping this step means cookies that spread like pancakes and stay flat. Form the dough into balls, then refrigerate them on a tray for at least 30 minutes. They’ll hold their shape better and bake more evenly.
- Use Room-Temp Butter: I was skeptical until I tried it—cold butter creates pockets that steam and make cookies cakey. Let your butter soften to the point where it leaves a slight indent when pressed (about 1 hour out of the fridge). Cream it with the sugar until it’s light and fluffy, or your cookies will turn out dense.
Essential equipment for perfect results
Mixing Essentials
Start with a stand mixer fitted with the paddle attachment—this makes mixing the dough effortless, especially when handling the sticky banana mixture. I use my KitchenAid Artisan Series because it handles dense doughs like this without overheating.
For hand mixers, opt for a high-powered model like the Cuisinart Smart Stick to ensure even blending. If you prefer manual mixing, a wooden spoon works, but be prepared for some elbow grease! 💪
Measuring Tools
Precision matters with these cookies, so invest in a digital kitchen scale for accurate measurements—especially for the flour and sugar. My OXO Good Grips scale is a game-changer for consistency. For dry ingredients like flour, use a fine-mesh sifter to aerate it before mixing, which prevents dense cookies.
A cookie scoop (like the OXO Good Grips 1.5-tablespoon model) ensures uniform dough balls, which bake evenly. Never eyeball measurements—this recipe relies on balance!
Toasted Walnut Prep
Toast your walnuts in a lightly oiled baking sheet at 350°F for 8-10 minutes, stirring halfway, until fragrant. A wire whisk helps distribute the nuts evenly. For extra crunch, chop them coarsely with a sharp chef’s knife or pulse briefly in a food processor (no need to over-process).
Pro tip: Use a small mixing bowl to toss the nuts with 1/2 tsp cinnamon while warm—this amplifies their flavor before folding into the dough. 🥜
Baking Sheets & Parchment
Line your baking sheets with high-quality parchment paper—I love If You Care brand—to prevent sticking and ensure easy release. Use two half-sheet pans (13x18 inches) for even baking. A pizza stone or steel placed on the middle rack improves heat distribution, but it’s optional.
For crisp edges, rotate the pans halfway through baking if your oven has hot spots. Avoid glass or dark-colored pans—they can over-bake the bottoms.
Cooling & Storage
Transfer baked cookies to a wire cooling rack to prevent soggy bottoms. For long-term storage, use airtight containers like Rubbermaid Brilliance with silicone seals to keep them fresh. To reheat, place cookies on a baking sheet in a 300°F oven for 2-3 minutes—they’ll regain that warm, gooey magic.
For freezing, arrange cookies on a tray, freeze solid, then transfer to a ziplock bag with parchment between layers to prevent sticking. ❄️

Frequently asked questions
Why do I need to chill the dough for these banana walnut cookies?
Chilling the dough for at least 30 minutes (or up to 1 hour) prevents excessive spreading while baking. The cold butter firms up, helping cookies maintain their shape, and allows the flour to hydrate properly for a tender crumb. Skipping this step often results in flat, cake-like cookies instead of the perfect chewy texture you want.
Can I substitute walnuts with another nut? Swap walnuts for pecans, almonds, or even hazelnuts—just toast them first to enhance flavor. For a nut-free version, use dried cranberries or chopped dates instead.
How do I fix cookies that spread too much?
If your cookies spread excessively, try these fixes: chill the dough longer (up to 2 hours), use 1 tablespoon of dough per cookie instead of 1.5, or increase the oven rack to the middle position. For future batches, ensure your butter is properly chilled and use a cookie scoop for consistent portions. Overbaking can also cause spreading—aim for 10-12 minutes max.
Can I make these cookies vegan?
Yes! Replace the butter with vegan butter or coconut oil (use 0.4 cup coconut oil solidified in the fridge), and swap eggs for 1/4 cup applesauce or flax eggs (1 tbsp ground flax + 3 tbsp water). For chocolate chips, choose dairy-free brands. The texture will be slightly denser but still delicious. Test with 1/2 tsp extra baking soda if the cookies seem flat.
How do I store these cookies to keep them fresh?
Store baked cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze them on a tray first, then transfer to a bag with parchment between layers (lasts 3 months). To revive stale cookies, warm at 300°F for 2-3 minutes. Keep them away from direct sunlight or humidity to prevent sogginess.
