Ingredients for banana nut oatmeal cookie
Seven wholesome ingredients create chewy banana nut oatmeal cookies with nutty crunch and caramelized edges.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 whole | Slightly squishy for sweetness |
| Old-Fashioned Rolled Oats 🌾 | 1 ½ cups | Not instant, for texture |
| Walnuts 🥜 | 1 cup | Chopped, toasted for flavor |
| Unsweetened Applesauce 🍎 | ½ cup | Replaces butter, binds dough |
| Pure Maple Syrup 🍯 | ½ cup | Vegan sweetener, not honey |
| Ground Flaxseed 🌱 | 1 tbsp | Mixed with 3 tbsp water for egg |
| Ground Cinnamon 🌶️ | 1 ½ tsp | Warm, aromatic, not sweet |
| Vanilla Extract 🍃 | 1 tsp | Pure, not imitation |
| Sea Salt 🧂 | ½ tsp | Fine grain, enhances flavor |
| Baking Soda 🧪 | ½ tsp | For leavening, not powder |
| Coconut Oil 🥥 | ¼ cup | Melted, vegan butter sub |
Ripe bananas are non-negotiable here—look for slightly squishy ones at the grocery store's produce section, not the rock-hard ones. Whole Foods or Trader Joe's usually have the sweetest varieties. The walnuts should be raw and toasted for maximum flavor; Costco's bulk section offers the best price per pound. For the oats, Bob's Red Mill old-fashioned rolled oats give the best texture—avoid quick oats, which get mushy. The coconut oil needs to be 100% pure, unrefined for that rich, tropical flavor that mimics butter.
No walnuts? Pecans or almonds work equally well, though texture will differ slightly. Short on applesauce? Mashed ripe avocado at half the amount adds creaminess without altering flavor. The maple syrup can be swapped for agave nectar or brown sugar, but maple delivers that subtle caramel note. For the flax egg, chia seeds work too—just use the same ratio. The baking soda is critical; baking powder won't give the same lift. If you're making these ahead, freeze the dough balls instead of chilling—they'll keep for months without drying out.
Storing these cookies is simple: cool completely on a wire rack to prevent sogginess, then transfer to an airtight container. They'll stay fresh for 5 days at room temperature or 3 months in the freezer. For reheating, 30 seconds in the microwave restores that just-baked warmth. I always make a double batch—one for immediate snacking, one to freeze for when cravings strike. The dough can be refrigerated for up to 3 days if you want to prep ahead, but don't skip the 30-minute chill before baking—trust me on this.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by this recipe because it’s literally 5 ingredients tossed together—no creaming butter, no precise measuring cups. Just mash those bananas, fold in the oats and walnuts, and let the applesauce and maple syrup bind it all. Honestly, my toddler could do it (and often does).
- Chewy Crunch Perfection: That walnut crunch against the soft oatmeal center? It’s the kind of texture that makes you pause mid-bite. The maple syrup adds just enough caramel depth, while the applesauce keeps them moist without tasting artificial. (Yes, even on a Tuesday night.)
- Packable for Anything: These hold up like champs—toss them in a lunchbox, pack for a road trip, or freeze half for later. I’ve sent them to soccer practice, used them as ice cream toppers, and even crushed them into overnight oats. They’re the ultimate flexible snack.
- Budget-Friendly Staples: Using pantry basics like oats, bananas, and walnuts means no specialty ingredients. The applesauce replaces butter, and maple syrup stretches further than honey. Between us, I’ve made 3 dozen with what I already had—and still had leftovers for days.
Step-by-step instructions for banana nut oatmeal cookies
Here's how to create cookies with chewy centers and a satisfying crunch from toasted walnuts.
👨🍳 Step 1: Prepare the Flax Egg and Melt the Coconut Oil
In a small bowl, combine the 1 tablespoon ground flaxseed with 3 tablespoons water and stir well. Let it sit for 5 minutes until it thickens into a gel-like consistency—this acts as our egg substitute. Meanwhile, melt the 0.25 cup coconut oil in a microwave-safe bowl for 20-30 seconds or until completely liquid. The flax egg should be fully gelled before using, forming a thick paste that binds the dough.
This step is crucial for texture. The flax egg adds moisture and structure, while the melted coconut oil ensures the cookies stay tender. If your flax mixture isn't fully thickened after 5 minutes, give it another stir and wait an extra minute—it needs to be completely set to prevent gummy cookies.
👨🍳 Step 2: Mix Wet Ingredients for Perfect Texture
In a large mixing bowl, mash the 2 whole ripe bananas with a fork until smooth, with just a few small lumps remaining. Add the melted coconut oil, 0.5 cup unsweetened applesauce, 0.5 cup pure maple syrup, 1 teaspoon vanilla extract, and the flax egg mixture. Stir until completely combined—this creates the base of our dough.
The bananas should be slightly squishy but not overly mushy. If they're too firm, let them sit at room temperature for another 10 minutes. The applesauce and coconut oil replace butter while keeping the cookies moist. Mix just until combined—overmixing develops gluten and makes the cookies tough.
👨🍳 Step 3: Combine Dry Ingredients for Crispy Texture
In a separate bowl, whisk together the 1.5 cups old-fashioned rolled oats, 1.5 teaspoons ground cinnamon, 0.5 teaspoon sea salt, and 0.5 teaspoon baking soda. Pour these dry ingredients into the wet mixture and gently fold with a spatula until just combined. Avoid overmixing—you should still see small oat clusters in the dough.
Old-fashioned oats give these cookies their signature texture, while the cinnamon adds warmth without sweetness. The baking soda provides lift, and the salt enhances all the flavors. Fold just until no dry spots remain—this prevents dense cookies. If the dough seems too sticky, chill it for 10 minutes before proceeding.
🥘 Step 4: Fold in Walnuts for Crunch
Chop the 1 cup walnuts into small pieces if they're large, then fold them into the dough using your hands or a spatula. The walnuts should be evenly distributed throughout the dough. Cover the bowl with plastic wrap and refrigerate for at least 30 minutes—this resting period is essential for flavor development and easier handling.
For best results, toast the walnuts first by spreading them on a baking sheet and baking at 350°F for 8-10 minutes until fragrant. This enhances their flavor significantly. The chilled dough will hold its shape better when scooping, resulting in thicker cookies with crispy edges and chewy centers.
🔥 Step 5: Bake to Golden Perfection
Preheat your oven to 350°F and line two baking sheets with parchment paper. Scoop the chilled dough into 1.5-tablespoon portions (about 12 cookies total) and place them 2 inches apart on the prepared sheets. Flatten each scoop slightly with your palm to about 0.5-inch thickness—this ensures even baking.
Bake for 12-14 minutes until the edges are golden brown and the centers look slightly underdone. The cookies will continue cooking on the hot pan after removal. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack. They should be soft in the middle with crispy edges and a satisfying walnut crunch throughout.
Pro Tips For Making Banana Nut Oatmeal Cookie
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana bits in your cookies scream "I didn’t try." Use a fork first, then press through a fine-mesh strainer to get rid of those stubborn fiber bits. Your cookies will bake evenly, and the texture will be silky, not chewy.
- Toast Walnuts First: Skip the raw walnuts—they’ll turn bitter and release grease that makes your cookies greasy. Toast them in a dry pan over medium heat for 3-4 minutes until fragrant, then chop. This adds depth of flavor and prevents a soggy bite.
- Chill the Dough: I was skeptical until I tried it: spreading dough straight from the bowl leads to flat, dense cookies. Press the dough into a disk, wrap it, and refrigerate for at least 30 minutes. The cold fat in the applesauce and maple syrup will firm up, giving you thicker, chewier cookies.
- Use Less Maple Syrup: Your recipe might call for ¼ cup, but trust me—start with 2 tablespoons. The bananas and applesauce already add natural sweetness, and too much syrup makes the cookies spread like pancakes. Taste the dough before baking; adjust with a pinch of cinnamon if needed.
Wine and beer pairings for this dish
Sweet White Wine
These cookies pair beautifully with a crisp Sauvignon Blanc from New Zealand, like Kim Crawford or Oyster Bay. The wine’s bright acidity and citrus notes complement the caramelized edges and nutty crunch, cleansing your palate between bites.
Look for a bottle with 12-13% alcohol—not too heavy to overpower the cookies’ natural sweetness. Serve slightly chilled for an extra refreshing touch. 🍷
Spiced Red Wine
A Pinot Noir with warm spice notes, such as La Crema Sonoma Coast, enhances the cinnamon and vanilla in these cookies. The wine’s medium body and black cherry undertones bridge the gap between the sweet banana base and the toasted walnuts.
Opt for a California or Oregon bottle—these regions excel at balancing fruitiness with subtle earthiness. Let the wine breathe for 10 minutes before serving to release its full aroma. 🍇
Creamy Beer Pairing
For beer lovers, a Belgian-style Witbier like Allagash White works wonders. The corianander and orange peel notes mirror the cookies’ cinnamon warmth, while the light effervescence cuts through the richness.
Alternatively, try a honey lager such as Honey Brown Ale from New Belgium—its sweet maltiness echoes the maple syrup’s caramel depth. Serve the beer ice-cold to contrast the cookies’ warm spices. 🍺
Coffee or Tea Finish
End your dessert experience with a dark roast coffee, like Peet’s Major Dickason’s Blend, to balance the cookies’ sweetness. The bitter chocolate notes in the coffee highlight the walnuts’ crunch and the banana’s natural fruitiness.
For a caffeine-free option, a chamomile tea with a splash of vanilla syrup enhances the cookies’ warm spices without overpowering them. Brew the tea stronger than usual to stand up to the rich flavors. ☕

Frequently asked questions
Why do these banana nut oatmeal cookies need to chill before baking?
The 30-minute chill is crucial for two reasons: it prevents spreading (so you get thicker cookies) and lets the flavors meld together. Without chilling, the dough stays too soft and spreads too much in the oven, resulting in thin, cakey cookies instead of the chewy, crunchy texture you want. Pro tip: If you're short on time, chill the dough for at least 20 minutes—just don't skip this step entirely!
Can I substitute walnuts for another nut or seed?
Swap walnuts for pecans, almonds, or even sunflower seeds—just adjust the amount to 1 cup total. Pecans add a buttery richness, while almonds give a slightly sweeter crunch. For extra protein, try chopped pumpkin seeds. Toast them first to enhance flavor, just like the walnuts. The key is keeping the total nut/seed quantity consistent for proper texture.
What if my cookies turn out too dense or cakey?
Dense cookies usually mean overmixing the dough or skipping the chill time. For next time: fold just until combined (small oat clusters should remain) and chill the dough fully. If you've already baked them, try reheating in the oven at 300°F for 5-10 minutes—this can help restore some chewiness. The flax egg also needs to be fully gelled before mixing, or it can make cookies gummy.
How can I make these cookies gluten-free?
Replace the oats with certified gluten-free rolled oats (like Bob's Red Mill GF oats) and use a 1:1 gluten-free flour blend (like King Arthur Measure for Measure) to replace 1/4 cup of the oats. The flax egg and coconut oil will still work perfectly. Test the dough consistency—if it's too dry, add 1 tablespoon almond milk. These adjustments maintain the chewy texture while making them safe for gluten-sensitive eaters.
Can I bake these cookies without an oven?
While not ideal, you can try baking them in a toaster oven or even a skillet on the stove. For the skillet method: Heat a cast-iron skillet over medium heat, add 1 tablespoon coconut oil, then place dough balls in the pan. Cover with a lid and cook for 8-10 minutes, flipping once. They won't be as crispy as oven-baked, but will still be warm and chewy. For best results, use a toaster oven at 350°F with parchment paper.
