Seriously, if you think baking takes hours and a million ingredients, you need to stop everything and try these Two-Ingredient Banana and Oat Cookies.

If you’re looking for a naturally gluten-free cookie that comes together faster than ordering takeout, these Two-Ingredient Banana and Oat Cookies are about to become your new best friend. They are perfect for busy weeknights or when those unexpected guests drop by!
Gathering What You Need for Two-Ingredient Banana and Oat Cookies
The best part about these cookies is that you probably have everything you need hiding in your fruit bowl right now. Seriously, the ingredient list for these Two-Ingredient Banana and Oat Cookies is shorter than my grocery receipt! We are keeping this super simple, but I do have a few key rules about the bananas you choose. Get your mixing bowl ready, because the prep time here is almost nothing!
Essential Ingredients for Two-Ingredient Banana and Oat Cookies
The foundation of these simple cookies relies entirely on two things: bananas and oats. You absolutely must use bananas that are extremely ripe—I mean, the skins should be mostly black! That’s where all the sweetness comes from. Check the list below to see the exact amounts before you start mashing. These are the only two things required to make the base of the Two-Ingredient Banana and Oat Cookies.
- 2 large very ripe bananas, mashed (about 1\u00bd cups)
- 1\u00bd cups rolled oats
Optional Add-ins for Flavor Variation
While the base recipe is fantastic, I usually can’t resist jazzing them up a little bit. If you want a bit more texture or a touch of chocolate decadence, these optional mix-ins are perfect. Chocolate chips melt slightly and give you that classic cookie feel. Walnuts add a nice crunch, and raisins plump up beautifully during the short bake time. Feel free to mix and match what you have on hand!
- \u2153 cup dark chocolate chips (Optional)
- \u00bc cup chopped walnuts (Optional)
- 2 tablespoons raisins (Optional)
Step-by-Step Guide to Making Two-Ingredient Banana and Oat Cookies
Alright, let’s get these baked! This process is so fast you’ll be amazed. We’re preheating the oven first, which is always my first move in any baking project—gotta get that heat ready! Line a baking sheet with parchment paper, please. Trust me on this; even though these cookies don’t spread much, having that easy cleanup is worth the 30 seconds it takes to lay down the paper.
The magic of these Two-Ingredient Banana and Oat Cookies starts with the mash. You need those bananas so soft they practically liquefy when you poke them. Use a fork, and mash them until they are as smooth as you can get them. A few tiny lumps are fine, but you want most of the texture to come from the oats, not big chunks of banana.
Preparing the Dough Base
Once you have your smooth banana mush, dump in all the rolled oats. Stir it up really well with a spatula or even that same fork. It’s going to look sloppy at first, maybe a little wet, but don’t panic! This is where patience comes in for about five minutes. Cover the bowl and just let it sit on the counter. Those oats are thirsty little things, and they soak up the banana moisture, turning that sloppy mixture into a real, scoopable dough. If you’re adding your optional chocolate chips or nuts now, fold them in during this resting time!
Remember, this dough won’t behave like regular cookie dough. It’s not going to be soft and pliable; it’s going to be thick and almost clumpy. That’s exactly what we want!
Shaping and Baking Your Two-Ingredient Banana and Oat Cookies
Now for the shaping! Grab a rounded tablespoon of that thick dough and drop it onto your prepared sheet. Space them about two inches apart because while they don’t spread much, they need a little breathing room. Here’s the key tip for these Two-Ingredient Banana and Oat Cookies: you have to flatten them yourself! Use the back of a spoon, or just gently press them down with your palm until they are about half an inch thick. If you skip this step, you end up with little mounds, not cookies.
Pop them into that preheated 350°F oven. They bake fast—only 13 to 15 minutes. You’re looking for the bottoms to just start turning a light golden brown. Don’t overbake them! They look a little soft when you pull them out, but they firm up beautifully as they cool. Let them sit right there on the hot pan for five minutes before you move them to a wire rack. If you try to move them too soon, they might crumble on you!
Expert Tips for Perfect Two-Ingredient Banana and Oat Cookies
I’ve made these cookies so many times I practically have the steps memorized, and I learned a few things the hard way! If you want your Two-Ingredient Banana and Oat Cookies to be chewy and perfectly sweet, you absolutely must pay attention to the bananas. I can’t stress this enough: brown spots mean brown sugar flavor, and that’s what makes these shine.
If your dough seems a little too wet after you mix in the oats—maybe your bananas were extra large or super mushy—just stir in an extra tablespoon of oats until it feels manageable. On the flip side, if it seems stiff, a tiny splash of milk (any kind works!) will loosen it right up. Remember what I said about flattening them? That’s critical. Since these don’t spread like traditional sugar cookies, you need to physically press them down before they go into the heat.
Finally, take them out right when they look set! They will continue to bake slightly on that hot sheet pan, and if you wait until they look perfectly crisp in the oven, they will be rock hard when they cool. Let them firm up on the rack, and then store them right away to keep all that soft texture locked inside.
Frequently Asked Questions About Two-Ingredient Banana and Oat Cookies
I get so many questions about these simple cookies because people can’t believe how easy they are! Most people want to know if they can make substitutions, and I always tell them that while the base is perfect, you have to be careful changing things up. Here are the most common things folks ask me about their Two-Ingredient Banana and Oat Cookies.
Are these Two-Ingredient Banana and Oat Cookies truly gluten-free?
That’s a great question, especially since they are often marketed as gluten-free cookies! Since the recipe only calls for rolled oats, they *can* be gluten-free. However, you absolutely must check your oat packaging. Standard oats are often processed near wheat, so if you have a serious sensitivity, make sure you buy oats specifically labeled as certified gluten-free. Otherwise, they are naturally free of wheat flour, which is the main thing!
How thick should the dough be before baking my Two-Ingredient Banana and Oat Cookies?
The dough for these Two-Ingredient Banana and Oat Cookies is much thicker than what you might expect from a standard chocolate chip cookie recipe. It will feel almost like thick oatmeal that you can scoop. Because the bananas don’t cause the cookies to spread out in the oven like butter does, you need to help them along! Make sure that when you scoop your tablespoon onto the sheet, you flatten it down firmly with the back of a spoon until it’s about half an inch thick. If you don’t flatten them, you’ll end up with little half-sphere balls instead of cookies!
Storing and Keeping Your Two-Ingredient Banana and Oat Cookies Fresh
Don’t let your hard work go to waste by letting these soft treats dry out! The key to enjoying your Two-Ingredient Banana and Oat Cookies over several days is proper cooling and storage. You must let them cool down completely on the wire rack before you even think about putting them away. If you seal them up warm, you’re just trapping steam, and they’ll get soggy instead of staying soft.
Once they are totally cool—and I mean cool to the touch all the way through—pop them into an airtight container. They stay wonderfully soft at room temperature for about three or four days. If you made a huge batch and need them to last longer, you can actually freeze them! Just layer them between pieces of wax paper in a freezer-safe bag. These simple cookies are just too good to waste! Follow us on Pinterest for more quick snack ideas!
Here is a quick guide to keeping track of your batches:
| Storage Method | Duration | Tip |
|---|---|---|
| Airtight Container (Room Temp) | Up to 4 days | Ensure cookies are fully cooled first. |
| Freezer | Up to 2 months | Separate layers with parchment or wax paper. |
Understanding the Nutrition in Two-Ingredient Banana and Oat Cookies
Since these Two-Ingredient Banana and Oat Cookies are made from just fruit and whole grains, they are a much better choice for a snack than most store-bought options! Keep in mind that the nutrition facts change a lot depending on how big your bananas were and if you added any of those optional mix-ins we talked about. The numbers below are just an estimate for two cookies made with only the base ingredients.
We are looking at basic energy here, focusing on calories, fat, carbs, and protein for a serving of two cookies. It’s good to know what you’re fueling up on! If you are interested in other healthy baking options, check out our banana bread bites.
