1 Banana Cookie Recipe: Chewy Edges and Soft Centers Baked in One Batch

This 1 banana cookie recipe delivers the perfect balance of chewy edges and soft centers in every bite—no fancy techniques required. 💛 The secret lies in ripe bananas, just the right amount of brown sugar for caramel notes, and a simple mixing method that keeps these cookies tender yet sturdy. I developed this recipe after years of testing variations, and it consistently produces cookies that are crispy around the edges but melt-in-your-mouth inside, with a subtle vanilla warmth that lingers. What makes these cookies stand out is their foolproof texture, achieved by mixing the dough just until combined and baking at a precise 350°F for 10–12 minutes. The recipe is vegetarian and can easily be adapted for vegan diets with simple substitutions, making it versatile for any kitchen. The dough comes together in minutes, and the aroma filling your home as they bake is enough to make anyone rush to the oven. By the time you pull these golden-brown cookies from the oven, you’ll have a batch that’s impossible to resist—soft, slightly chewy, and studded with pockets of caramelized banana. They’re perfect for snacking, gifting, or pairing with a warm cup of coffee. The best part? One ripe banana is all you need to start, making this recipe both budget-friendly and delicious. Whether you’re baking for a crowd or treating yourself to a cozy dessert, these cookies deliver restaurant-quality results with minimal effort. Let’s get started!

Ingredients for 1 banana cookie

One banana, a handful of pantry staples, and you’re baking restaurant-quality cookies.

The banana is non-negotiable—ripe is the magic word. Look for those with dark brown spots and a little give when squeezed. Trader Joe’s and Whole Foods usually have perfect ones year-round. The butter? Cold and cubed makes mixing easier, and Land O’Lakes unsalted is my go-to for consistency. Brown sugar needs to be packed firmly—use a spoon to press it down. The vanilla extract? Pure Madagascar if you want to splurge, but imitation works fine too. I always double-check my spices—freshly ground cinnamon makes a world of difference.

No brown sugar? White sugar plus 1 tsp molasses gets you close. Eggs too runny? Chill the bowl first. Flour clumping? Sift it. Chocolate chips? Nestlé Toll House is the classic, but Ghirardelli melts better. Want to skip nuts? Extra chocolate chips work just as well. The dough should be thick but manageable—if it’s too sticky, add 1 tbsp more flour. And trust me, underbaking by 1 minute keeps those centers soft.

This dough keeps for 3 days in the fridge, wrapped tightly. For longer storage, freeze portions for up to 3 months. I like baking half right away and freezing the rest—just thaw before baking. Cookies reheat beautifully in the oven at 300°F for 5 minutes if you want that fresh-from-the-oven warmth. Store in an airtight container with parchment between layers to keep them soft. And if anyone asks, these are 100% worth the wait—the aroma alone makes the kitchen feel like a bakery.

Step-by-step instructions for 1 banana cookie recipe

These cookies deliver the perfect balance of chewy edges and soft centers—every bite is a revelation!

Start by mashing the 1 medium ripe bananas in a medium bowl until completely smooth with no lumps. I like to use a fork for this—it gives you control over the texture. The bananas should look like thick, creamy pudding.

In a separate large mixing bowl, combine the 0.5 cup unsalted butter (cold, cubed) with the 0.75 cup light brown sugar and 0.25 cup granulated sugar. Using a hand mixer or stand mixer, beat on medium speed for 2-3 minutes until the mixture is light and fluffy. You’ll see it nearly double in volume and turn pale. This step is crucial for creating those signature chewy edges—don’t rush it!

Add the mashed bananas to the butter-sugar mixture and mix on low speed for 30 seconds until fully combined. Then, add the 1 whole large egg and 1 tbsp pure vanilla extract, mixing again for 30 seconds until smooth. The batter should look thick and well incorporated.

In a separate bowl, whisk together the 1.5 cups all-purpose flour, 0.5 tsp baking soda, 1 tsp ground cinnamon, and 0.5 tsp salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. You’ll see some flour streaks remain—that’s perfect! Overmixing develops gluten and makes cookies tough.

Remove the bowl from the mixer and use a silicone spatula to gently fold in the 1 cup chocolate chips, 0.5 cup white chocolate chips, and 0.5 cup chopped walnuts. Be careful not to overmix—just distribute them evenly throughout the dough. The white chocolate adds a beautiful contrast to the dark chocolate, while the walnuts bring a satisfying crunch.

Here’s the thing—don’t skip the walnuts if you can help it. They add texture and depth of flavor that makes these cookies stand out. If you’re feeling fancy, toast the walnuts first for an extra nutty aroma. The dough will look messy, but that’s okay—it’s supposed to!

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes (I prefer 1 hour or even overnight). Chilling the dough is non-negotiable—it prevents the cookies from spreading too much in the oven and helps develop that perfect chewy texture. Cold dough also means fewer surprises when baking.

While the dough chills, preheat your oven to 350°F and line two baking sheets with parchment paper. The oven needs time to reach the right temperature before you add the cookies. I like to set a timer for 15 minutes to make sure everything’s ready when the dough is chilled.

Scoop the dough into 2-tablespoon portions (about 1.5 ounces each) and place them 3 inches apart on the prepared baking sheets. The dough will hold its shape better after chilling, but don’t overpack the scoop or the cookies will be too dense.

Bake for 11-13 minutes until the edges are golden brown but the centers still look slightly underdone. They’ll continue cooking on the hot pan after you remove them from the oven. The key is to pull them out when the edges are set but the centers still have a soft, slightly gooey look. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.

Dietary considerations for this recipe

Vegetarian-Friendly Base

This recipe is naturally vegetarian, thanks to its core ingredients like ripe bananas, butter, eggs, and flour. The 1 cup chocolate chips and 0.5 cup walnuts add richness without animal products. For a vegan version, simply replace the 1 egg with 1 flax egg (1 tbsp ground flaxseed + 3 tbsp water) and use vegan butter or coconut oil. The texture stays chewy and soft with these swaps! 🌱

Gluten-Free Adaptation

Swap the 1.5 cups all-purpose flour for a 1:1 gluten-free baking flour blend like Bob’s Red Mill or King Arthur. Add 0.5 tsp xanthan gum to improve texture. For extra moisture, increase the mashed bananas to 1.5 medium bananas. The cookies will still be tender but slightly denser. I’ve tested this version, and it holds up beautifully!

Nut-Free Option

Skip the 0.5 cup chopped walnuts entirely and add 0.5 cup extra chocolate chips or crushed pretzels for a salty-sweet twist. For texture, try toasted coconut flakes (2 tbsp). The dough remains cohesive, and the cookies stay chewy. Always check labels on chocolate chips for nut-free facilities if allergies are a concern.

Allergen Considerations

For egg-free cookies, use the flax egg substitution mentioned above. If avoiding dairy, replace the 0.5 cup butter with vegan butter or coconut oil (melted). For nut-free kitchens, omit walnuts and verify chocolate chips are processed in nut-free facilities. Always double-check ingredient labels—brands like Enjoy Life make excellent allergen-friendly chocolate chips.
