Why you’ll love our healthy banana oatmeal bars!
Banana Oatmeal Bars with Greek Yogurt are one of those recipes that prove wholesome snacks can be genuinely delicious. 🍌 Made with just a handful of everyday ingredients, they’re naturally sweetened with ripe bananas, packed with hearty oats, and finished with a few dark chocolate chips for just the right amount of sweetness. They’re perfect for breakfast, an afternoon snack, or meal prep for the week ahead.
The inspiration came from our popular banana baked oatmeal with Greek yogurt. Louise and I loved how the yogurt made that recipe soft and tender, so we wondered if it could do the same for oatmeal bars. After several test batches and a few small tweaks, we found the perfect balance. The Greek yogurt is the secret ingredient, keeping the bars moist and soft without the dense, gummy texture that many oat bars have. ✨
We also used less peanut butter than most recipes, letting the banana flavor shine while keeping the bars lighter and more balanced. The result is a snack that slices beautifully, stays tender for days, and all without any added sugar or sweeteners.
These bars are fiber-rich, protein-rich, and naturally gluten-free when made with certified gluten-free oats. They fit beautifully into a Mediterranean-style eating pattern and are an easy way to keep a nutritious homemade snack in the fridge, making wholesome choices simple whenever hunger strikes. 💛

Ingredients
Full ingredients and substitutions are in the recipe box below.
- Bananas: use very ripe, spotty bananas for the best natural sweetness and soft texture. Substitute mashed sweet potato or pumpkin puree for a less sweet twist.
- Greek yogurt: keeps these healthy banana oatmeal bars soft, moist, and not gummy. Use low-fat Greek yogurt, full-fat Greek yogurt, or Skyr for even more protein. For a dairy-free version or if you don’t have Greek yogurt, substitute unsweetened applesauce or an extra mashed ripe banana.
- Peanut butter: adds richness and helps bind the bars. Substitute almond butter, cashew butter, sunflower seed butter, or tahini for a nut-free option.
- Vanilla extract: makes the bars taste sweeter and more like banana bread. Substitute cinnamon, pumpkin spice, or a little orange zest.
- Rolled oats: give the bars structure and make them a hearty make ahead breakfast. Use certified gluten-free oats if needed, or quick oats for a softer texture.
- Dark chocolate chips: add just enough sweetness without making these feel like dessert. Substitute chopped dark chocolate, chopped walnuts, pecans, raisins, dried cranberries, or cacao nibs for banana oat snack bars with a different texture and flavor.
How to Make Banana Oatmeal Bars
1. Make the banana oat mixture
Preheat the oven to 375°F (190°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang on two opposite sides to use as handles later.
Mash the ripe bananas in a large bowl until mostly smooth. Add the Greek yogurt, peanut butter, and vanilla extract, then stir until creamy and well combined.
Add the rolled oats and dark chocolate chips. Stir again until the mixture is evenly mixed and quite thick.
2. Press and bake
Transfer the mixture to the prepared pan. Spread it out evenly, then press the top firmly with the back of a spoon so the bars bake into an even layer.
Sprinkle a few extra chocolate chips on top, if you like.
Bake at 375°F (190°C) for 12 to 15 minutes, or until the center looks set and feels slightly firm. The bars will continue to firm up as they cool, so don’t overbake them.
3. Cool and slice
Let the banana bars with oats cool completely in the pan. This helps them slice cleanly and hold their shape.
Lift the bars out using the parchment paper, then cut into squares. Enjoy right away, or refrigerate them for an easy grab-and-go breakfast or snack throughout the week.
Tips
- Use very ripe bananas: Bananas with plenty of brown spots are sweeter, mash more easily, and give the bars the best flavor and moisture.
- Measure the mashed banana: Aim for about 1 cup. Too little can make the bars dry, while too much may keep them from setting properly.
- Choose rolled oats: Old-fashioned rolled oats give the best chewy texture. Quick oats work too but make the bars softer.
- Use thick Greek yogurt: Thick Greek yogurt is the secret to soft, moist bars that aren’t gummy. Low-fat, full-fat, and Skyr all work well.
- No Greek yogurt? Substitute ⅓ cup unsweetened applesauce or ½ cup mashed ripe banana (about 1 additional banana). Applesauce keeps the bars lighter, while extra banana makes them even softer with a stronger banana flavor.
- Use natural peanut butter: Stir it well before measuring so the oil is fully incorporated. Natural peanut butter gives the cleanest flavor.
- Press the mixture firmly: Use the back of a spoon or measuring cup to compact the mixture into an even layer so the bars hold together after baking.
- Don’t overbake: Bake just until the center is lightly set. The bars will continue to firm up as they cool, so there’s no need to leave them in longer.
- Cool before slicing: Let the bars cool completely for clean slices and the best texture.
- Store in the fridge: Keep the bars in an airtight container in the refrigerator for up to 1 week or freeze them for up to 3 months.
Frequently Asked Questions
Yes. Replace the Greek yogurt with ⅓ cup unsweetened applesauce or ½ cup mashed ripe banana (about 1 additional banana). Applesauce keeps the bars a little lighter, while extra banana makes them softer with an even stronger banana flavor.
Yes. Quick oats work well, but they’ll give your banana oat bars a softer, less chewy texture. Rolled oats are our favorite because they create sturdier bars that hold their shape better.
This recipe is easy to customize. Try chopped walnuts, pecans, raisins, dried cranberries, shredded coconut, pumpkin seeds, sunflower seeds, or chopped dark chocolate. Keep the total amount of add-ins to about ½ cup so the bars stay together.
Let the bars cool completely, then store them in an airtight container in the refrigerator for up to 1 week. They also freeze well for up to 3 months. They’re perfect for healthy banana snacks or a quick breakfast—just thaw overnight in the fridge or let them sit at room temperature for 10 minutes before enjoying.
The bars are done when the center looks set and feels slightly firm when gently pressed. Don’t wait for them to become hard in the oven. They will keep firming up as they cool, which keeps the texture soft and moist instead of dry.
They may need more cooling time. These bars slice best once they are completely cool, and even better after chilling in the fridge. Also, make sure to press the mixture firmly into the pan before baking so the oats, banana, yogurt, and peanut butter hold together.
Yes. Substitute almond butter, cashew butter, or sunflower seed butter. Sunflower seed butter is a good nut-free option, while almond butter gives these banana breakfast bars a milder flavor. For a lighter taste, tahini also works, but it will make the bars slightly more savory.

Hi! We are Nico & Louise
We're here to share easy, healthy, and delicious recipes 🌿✨.
Welcome to our blog, we are glad you are here.
Moist, flavourful and quick to make
oops — meant “whole grain breaD”…..
These bars were delicious with our morning coffee!! I followed the recipe using the frozen bananas I had and just mashed those up really well and let them warm up quite a bit. I had some whole milk Greek yogurt that I had already strained in the frig so that’s what I used in the recipe. It was super thick since I like to spread it on my homemade “vollkorn brot” (whole grain break) like a fresh cheese (Quark in German). I did use the natural peanut butter and rolled oats as recommended. I ended up adding extra craisins, dried cherries and currents plus pecans and just a bit of dark salted chocolate bar that I chopped. Really moist and delicious!! And not too sweet!!! Thanks for sharing this easy recipe!
Hello, do you think you can use frozen bananas? I would thaw them, Of course .
I always save them for when I make my banana bread and I usually drain the excess water out.
Any opinion? Thank you
Hi AnnMarie,
We haven’t tested the bars with thawed frozen bananas, so I’m not completely sure. With that being said, draining off the excess liquid, as you mentioned, sounds like a sensible approach, and it could work as the recipe is quite forgiving 🙂
Also, you might need to bake the bars a couple of minutes longer. Enjoy!!
Kindest,
Louise
Delicious healthy snack. Followed recipe exactly, 13 minutes in the oven. Your recipes continue to be perfect! Great for small breakfast as well 😊
Tasted great put of the oven. I forgot to refrigerate overnight, are they still ok to eat?
Hi Dan,
I’m so glad you enjoyed them!!
It depends on how long they were left out. Since they contain Greek yogurt, if they sat at room temperature overnight (more than about 2 hours), I’d recommend discarding them to be on the safe side.
Kindest,
Louise
I followed the recipe exactly and after 15 minutes it still hadn’t set in center but the recipe stressed not to over bake so I removed it and placed on a cooling rack. After 3 hours I tried it and the instant oats tasted raw and nasty. I have no plans to make this again. I think it needs to be edited. Also, even dark chocolate contains sugar so you may need to change the recipe name.
Hi Kate,
Thanks so much for taking the time to share your feedback. I’m sorry the bars didn’t turn out as expected for you.
The bars should be baked for 12–15 minutes, or until the center looks set and feels slightly firm. If the center is still soft after 15 minutes, it’s best to leave them in a little longer, as ovens can vary. They will continue to firm up as they cool, but the center should already be set when they come out of the oven.
I appreciate your honest feedback.
Kindest,
Louise
Dark chocolate chips have sugar. So saying there is no sugar is not quite true. This is problematic for those who can eat NO sugar!!!
I purchased zero sugar dark chocolate chips. I got them from Costco. 0g sugar and 0g added sugar. Its not hard to find.
Sadly I feel this really does need some honey or brown sugar. I will eat it but there’s no way the husband or kids will. Its a great recipe but if I make it again I’ll sweeten it up a bit.
Hi Laura, thanks so much for your feedback! 😊
These bars are intentionally not very sweet, as they’re naturally sweetened with ripe bananas. If you prefer a sweeter snack, adding a little honey or brown sugar is absolutely fine.
Thanks again for giving the recipe a try. Kindest,
Louise
Hi Nico, I made these bars today and they came out really well. I used Barney brand crunchy Almond Butter that is lower in sugar than most peanut butter or sunbutter, so they will need 1/3 cup of mini choc chips to satisfy my tastebuds. I may even add some chopped walnuts or raisins for the next batch. Also, since they are mini squares, I wanted to munch on 2 of them. Thanks for the recipe idea. How about doubling the amount and freezing them? Have you tried that yet?
Hi Eileen, thanks so much for sharing! Your version sounds delicious 🙂
I would assume these would freeze well, although we haven’t tested it ourselves. Just let them cool completely, then store them in an airtight container or freezer bag. All the best,
Louise
