This vegan oatmeal cookie recipe with banana delivers no-bake chewiness and hidden banana sweetness—no one will guess they're secretly healthy. 💚 I perfected this after years of testing vegan cookie recipes, and the secret lies in the flax eggs and ripe banana mash that bind the dough without needing an oven.
The magic happens with simple ingredients: rolled oats, mashed banana, flax eggs, and a touch of maple syrup for natural sweetness. Unlike traditional oatmeal cookies, these hold their shape without baking, thanks to the flax egg's binding power and the banana's natural moisture.
The texture is chewy yet sturdy, with a subtle caramel note from the banana that deepens as they sit.
What makes these cookies special is their versatility—add chocolate chips, chopped nuts, or cinnamon for extra flavor. They're perfect for meal prep, snacking, or gifting, and the vegan substitutions (like flax eggs and coconut oil) ensure they're just as satisfying as their non-vegan counterparts.
No one will miss the eggs or butter.
The recipe is designed for minimal effort, maximum flavor, with a dough that comes together in minutes and requires no baking. Whether you're vegan, avoiding gluten, or just looking for a healthier treat, these cookies deliver restaurant-quality results with pantry staples. Let's get started!
Ingredients for vegan oatmeal cookie recipe banana
Simple pantry staples transform into chewy, no-bake vegan cookies with banana's natural sweetness.
| Ingredient | Amount | Notes |
|---|---|---|
| Rolled Oats 🌾 | 2 cups | Old-fashioned, not quick oats |
| Ripe Bananas 🍌 | 2 medium | Mashed to 1 cup total |
| Ground Flaxseed 🌱 | 3 tbsp | For flax eggs (mix with 9 tbsp water) |
| Maple Syrup 🍯 | ½ cup | Pure, grade B preferred |
| Coconut Oil 🥥 | ½ cup | Melted, solid at room temp |
| Vanilla Extract 🌿 | 1 tsp | Pure alcohol-free preferred |
| Cinnamon 🌶️ | 1 tsp | Ground, not cassia |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Chocolate Chips 🍫 | 1 cup | Vegan, dairy-free chips |
| Water 💧 | 9 tbsp | For flax egg mixture |
The bananas are the secret—ripe ones mash smoothly and add natural sweetness without extra sugar. Trader Joe's and Whole Foods usually have the perfect spotty ones, but any overripe bananas from your counter work too. The rolled oats should be old-fashioned, not quick oats—they hold shape better without baking. For the flax eggs, Bob's Red Mill ground flaxseed is my go-to, but any store brand works if it's fresh. The coconut oil needs to be melted but not hot—microwave for 40 seconds if it's solid.
No maple syrup? Agave nectar or date syrup works in a pinch, though maple gives that classic caramel note. Short on chocolate chips? Chopped walnuts or pecans add crunch, or skip them entirely for a simpler cookie. The vanilla extract should be pure—imitation extracts won't have the same depth. For extra flavor, add 1 tsp cinnamon or 0.5 tsp nutmeg. These cookies hold their shape without baking thanks to the flax eggs and coconut oil, so don't worry if the dough seems too wet.
The dough keeps for 3 days in the fridge, covered tightly. Portion into 1-tbsp balls and flatten slightly before chilling. They firm up beautifully in the fridge for 1 hour before serving. For longer storage, freeze portions for up to 3 months. The flavor actually improves after 24 hours as the banana caramelizes—perfect for meal prep or gifting.
Why You'll Love This Recipe
- No-Fuss Mixing: I swear by the "squish-and-go" method—mashed banana, oats, and flaxseed blend into a dough that doesn’t even need a mixer. Just fold in the maple syrup and coconut oil, then roll into balls. Honestly, the only tool I use is a fork.
- Banana-Caramel Magic: That ripe banana isn’t just filling—it turns golden and chewy with a maple-kissed sweetness that tastes like dessert. The flaxseed adds a nutty depth, while the coconut oil keeps them tender without greasiness. (Yes, even on a Tuesday night.)
- Snack Attack Ready: These hold up for days in the fridge, so I bake a batch on Sundays and grab one straight from the jar for breakfast or an afternoon pick-me-up. They’re also my go-to for lunchboxes—kids love the texture, and they’re packed with fiber.
- Pantry Staple Power: No weird ingredients here—just oats, bananas, and a few basics you already own. The flaxseed gives them protein, the maple syrup cuts costs vs. honey, and coconut oil replaces butter without breaking the bank. Budget-friendly and satisfying? That’s my kind of recipe.
Step-by-step instructions for vegan oatmeal cookies
Here's the straightforward method for chewy, no-bake cookies packed with banana flavor.
👨🍳 Step 1: Prepare the Flax Egg Mixture
In a small bowl, whisk together the 3 tablespoons ground flaxseed and 9 tablespoons water. Let this mixture sit for 5 minutes until it thickens into a gel-like consistency—this is your flax egg. The texture should resemble raw egg whites but be slightly more viscous. This binding agent replaces traditional eggs in vegan baking.
While you wait, mash the 2 medium ripe bananas until completely smooth with no visible chunks. You should end up with about 1 cup of mashed banana. The riper the bananas, the sweeter and more flavorful your cookies will be. If your bananas aren't perfectly ripe, place them in a paper bag with an apple for 24 hours to speed up the ripening process.
🍳 Step 2: Combine Wet Ingredients
In a large mixing bowl, combine the mashed bananas with the 0.5 cup melted coconut oil, 0.5 cup maple syrup, 1 teaspoon vanilla extract, and the thickened flax egg mixture. Stir everything together until fully incorporated and smooth. The coconut oil should be completely melted—if it's solid, warm it in a bowl set over hot (not boiling) water for 1-2 minutes until fully liquid.
Add the 1 teaspoon cinnamon and 0.5 teaspoon sea salt to the wet ingredients and mix well. The salt might seem excessive, but it balances the sweetness and enhances all the flavors. This is also when you want to taste your mixture—if it needs more sweetness, add 1-2 teaspoons more maple syrup. The mixture should be thick but pourable, similar to cookie dough consistency.
👨🍳 Step 3: Mix in Dry Ingredients
Add the 2 cups rolled oats to the wet mixture and stir until everything is evenly combined. The oats will absorb some of the liquid, but don't worry if it looks dry—this is normal. Fold in the 1 cup chocolate chips by hand using a silicone spatula, making sure they're evenly distributed throughout the dough.
Here's the thing—this dough will be thicker than traditional cookie dough. If it seems too stiff to handle, you can add 1-2 tablespoons more water to help it come together. The texture should be like thick cookie dough that holds its shape when you press it between your fingers. Don't overmix at this stage—just combine until all the oats are moistened and the chocolate chips are distributed.
⏰ Step 4: Chill the Dough
Transfer the dough to a bowl, cover it tightly with plastic wrap, and refrigerate for at least 30 minutes (I prefer 1 hour for best results). Chilling is crucial for two reasons: first, it firms up the dough so it holds its shape when you scoop it, and second, it allows the flavors to meld together more thoroughly. The longer it chills, the more developed the banana flavor will be.
While the dough chills, preheat your oven to 350°F and line two baking sheets with parchment paper. The dough will be quite firm after chilling, so let it sit at room temperature for 5-10 minutes before scooping to make it easier to handle. This step ensures you get perfectly formed cookies that maintain their shape during baking.
🔥 Step 5: Bake to Golden Perfection
Using a cookie scoop or tablespoon, portion the dough into 12 equal balls, each about 1.5 tablespoons in size. Place them 2 inches apart on the prepared baking sheets—they won't spread much, so you want room for them to grow slightly. Gently flatten each ball with your palm to about ½-inch thickness.
Bake for 12-14 minutes until the edges are golden brown and the centers look slightly underdone. They'll continue cooking on the hot pan after you remove them from the oven. The cookies should be soft but firm to the touch—if you press gently and it leaves a slight imprint that doesn't bounce back, they're done. Rotate the baking sheets halfway through for even baking.
Pro Tips For Making Vegan Oatmeal Cookie Recipe Banana
- Mash Bananas Thoroughly: Skip the blender—your hands will do better work here. Overripe bananas with brown spots break down into a smoother, stickier dough when you press them through a fork or mash them with a potato masher. That extra effort means fewer lumps and a chewier cookie texture.
- Use Cold Coconut Oil: Measure it straight from the fridge—solid coconut oil mixes more evenly into the oat batter. If you melt it first, the dough gets greasy and spreads too much when baking. Just scoop, soften slightly with your hands, and let the heat of the mix do the rest.
- Don’t Overmix the Dough: Stir just until the oats are coated and the bananas are incorporated. Every extra turn makes the cookies dense and tough. The flaxseed egg (ground flax + water) needs minimal handling—once it’s bound, stop.
- Bake in Two Batches: Crowding the pan turns these into flat, sad cookies. Use half the dough per sheet, spacing them 2 inches apart. The edges will crisp while the centers stay soft—just like they should. (Yes, it means a second tray, but trust me.)
Make-ahead tips for this dish
Dough Prep Ahead
Make the dough up to 3 days in advance and store it in an airtight container in the fridge. The flavors deepen as the banana caramelizes, giving you cookies that taste even better the next day.
I like to portion the dough into 1-tbsp balls while it's still cold, then flatten slightly before returning to the container. This saves time later and ensures perfectly shaped cookies. 💫
Freezing Portions
For long-term storage, freeze the shaped dough balls on a parchment-lined tray for 1 hour until firm. Transfer to a freezer bag with parchment paper between layers to prevent sticking. They'll keep for up to 3 months—just thaw in the fridge overnight before baking.
No need to adjust baking time; they'll come out just as chewy and delicious as fresh dough. ❄️
Batch Baking Tips
Double the recipe for 24 cookies and use two baking sheets for even browning. I recommend baking in two batches to avoid overcrowding—this ensures even heat distribution and golden edges.
Label your containers with the date to track freshness. The dough can also be frozen in a single batch for up to 6 months before portioning. 🔥
Flavor Boosting
Add 1 tsp cinnamon or ½ tsp nutmeg to the dough for extra warmth. For a tropical twist, fold in ½ cup shredded coconut or chopped macadamia nuts. The dough's natural sweetness pairs perfectly with these additions, but taste before baking to adjust sweetness if needed.
These variations work best when made fresh, but the base recipe holds up beautifully when prepped ahead. 🌴
Gifting Ready
Package cooled cookies in cellophane bags tied with twine for a professional touch. Add a handwritten note about the vegan ingredients and banana sweetness—people love the surprise! Store in an airtight tin for up to 5 days at room temperature.
The cookies stay soft and chewy, making them perfect for holiday gifts or office treats. 🎁
Reheating Leftovers
Warm cookies in the oven at 300°F for 3-5 minutes to restore their soft texture. Microwave for 10 seconds if you're in a hurry, but they'll be slightly firmer.
I avoid the microwave unless necessary—it can make the oats dry out. These cookies reheat beautifully, so they're ideal for meal prep or snacking throughout the week. 💡

Frequently asked questions
Can I use quick oats instead of rolled oats?
Not ideal for this recipe! Rolled oats hold their texture better during baking and give that classic chewy oatmeal cookie feel. Quick oats will make the cookies crumble more easily. If you're in a pinch, use old-fashioned oats—they're the same as rolled oats and work perfectly.
What if my bananas aren't ripe enough?
No problem! Place unripe bananas in a paper bag with an apple for 24 hours to speed up ripening. The bananas should soften and develop brown spots—this means they're perfect for mashing. Overripe bananas (blackened) work too, but they'll make the cookies sweeter.
Why does my dough look too wet or dry?
Dough consistency varies based on banana ripeness and humidity. If it's too wet, add 1-2 tbsp more oats to absorb moisture. Too dry? Stir in 1 tbsp water or melted coconut oil. The dough should hold shape when pressed but still be pliable. Don't overmix—just combine until just combined.
Can I make these cookies without chocolate chips?
Skip the chocolate chips and add ½ cup chopped nuts (walnuts, pecans) or ½ cup shredded coconut for texture. For a simpler cookie, just omit them—the banana and oats provide enough flavor. Store-bought vegan chips work best if you prefer chocolate.
How do I prevent the cookies from sticking to the pan?
Always use parchment paper or a silicone baking mat on your trays. For extra insurance, lightly grease the parchment with coconut oil before placing the dough. The cookies won't spread much, so spacing them 2 inches apart ensures even baking and easy release. No sticking guaranteed!
