When is a Banana Ripe Enough for Baking?

First, a quick tip! People ask me all the time how they’ll know if a banana is ripe enough for baking. Do your bananas look gross? Like, really gross? Then they’re ready! The more ripe a banana, the sweeter the batter.

In a pinch, you can ‘ripen’ bananas in your oven. Simply place them on a baking sheet and then bake for 30 minutes or so in a 300°F oven. Keep in mind, though, that oven-ripened bananas don’t quite have the same sweetness to them.

How to Make Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars

  • To make the batter, first, cream the butter, 1/2 cup peanut butter, and brown sugar together in the bowl of an electric stand mixer until light and fluffy. Next, add your eggs, one at a time, beating well after each addition. Then, beat in a teaspoon vanilla extract.
  • In a separate large bowl, whisk together the dry ingredients (oats, baking powder, and baking soda. Note there’s no salt in this recipe). Next, add the oat mixture to the wet ingredients in the stand mixer and beat on low to medium speed until well combined.
  • Fold in the mashed banana and then 1 cup of chocolate chips.

  • To make the streusel, first stir the peanut butter, brown sugar, and oats together in a small bowl with a fork until crumbly. Next, gently mix in 1/2 cup chocolate chips.

  • After spreading the bread batter evenly into a prepared baking dish, sprinkle the streusel evenly over the batter. As always, you can line your baking pan with parchment paper for an easier clean. There you have it!

  • Bake at 350°F for 40-45 minutes, or until a toothpick inserted near the center comes out clean.

Finally, let cool in the pan at least 30 minutes, cut the bread into bars and enjoy a bit of chewy chocolatey heaven. Supposedly, this recipe makes 24 servings, but I’ll let y’all be the judge of that. Serve and enjoy! Your crew will devour these treats before you can say, “Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars with a Peanut Butter Oat Streusel!”

Substitutions and Storage

Nut Butters: I haven’t tried it, but I bet this recipe would work well with whatever nut butter (almond butter, cashew butter, etc.) or seed butter you choose, if peanut isn’t your thing.

Gluten Free: There’s no flour in these banana oatmeal bars, but if you want to make sure it’s free of gluten, choose gluten-free oats.

Store at room temp in an airtight container for up to three days (they won’t last that long!). Or place in a freezer-safe container and freeze for up to three months.

  1. Hi I just made these today, me and my son love them especially him. He wanted more after. I was wondering what’s the best way to store them? Can I leave them in their pan and just put plastic wrap on it?

    1. Hi, Samantha! I’m so happy he loves them! Store at room temp in an airtight container or wrapped tightly with plastic wrap for up to three days. Or place in a freezer-safe container and freeze for up to three months. Hope this helps!

  2. Wondering if there is a substitute for banana that would work well and not change the consistency? Perhaps pumpkin puree or, cooked zucchini or mashed sweet potato would work?

    1. Hi! I think pumpkin puree or applesauce would be the best substitutes for this recipe. I hope this helps and that it bakes up great. Enjoy!

  3. These were such a hit at home and at work. They barely lasted a day! I was able to get 15 out of this recipe… definitely not 24! 😂






    1. Hi, Cristan! I am so happy ya’ll enjoyed them so much! They go quickly at our house, too. Thank you so much for sharing ❤️

  4. I am an avid (and fairly skilled) baker. I made this recipe exactly as written. We found the results to be too sweet and too unpleasantly soft. There seems to be a problem with the ratio of oats, bananas, and sugar. So much so that the family voted to bin them after tasting.
    I’ll be returning to other more successful gluten free recipes.






    1. Hi Alyson! This sounds like a matter of preference unless you underbaked them to where they would be mushy. They are certainly sweet and supposed to be soft and tender like a good banana bread should be. I hope you find another recipe that your family enjoys! Best wishes!

  5. Wow, these are incredible, Maegan!! They were also a hit with my toddler, who gave them a resounding “nummy!” (No surprise there; how could anyone not love these?!)

    The streusel topping is delicious. I’ve never made a streusel with a peanut butter base before, but it really enhanced the flavor and texture of the bars.

    I made a couple of small changes when I made these. I used chopped up Lindt bittersweet chocolate bars instead of chocolate chips, salted butter instead of unsalted, and added a half cup of flour to the batter.

    I cut these into 24 servings. With my modifications, a serving has about 250 calories and provides 5.2 g of protein and 2.4 g of fiber. They are the perfect semi-healthy bars, nourishing without sacrificing flavor or texture.

    Thank you so much for the recipe! This one is a keeper.






  6. Hi Maegan, I make this recipe often and my children absolutely love it. Unfortunately for the last two times my bars gone stringy and got black strings in it just on the third day itself. I kept them in airtight but at room temp. I’m in UK and it is getting warm here. Any advice, suggestion would be welcome. Thank you!

    1. Hi, Aarti! Stringy? I’ve never experienced that. Could it possibly be the stringy banana fibers turned dark? That happens pretty quickly after exposed to air, and probably nothing to worry about. You could take care to remove those long fibers before mashing the banana, if that’s the cause. But you could also keep your bars refrigerated if you’re concerned they’re spoiling too quickly. Hope this helps!

  7. Hello! This is our first time using this recipe. I had to go outside while it was baking, and I walked in the house to this aroma… I was amazed! Of course we couldn’t wait for 30 minutes after it came out 😆
    Thank you so much for sharing this recipe. It’s a keeper!

    1. Hi, Carol! It makes my kitchen smell so good! I’m glad you enjoyed that amazing smell, too. Thank you for sharing!

    1. Hi, Cara! Do you mean you have old fashioned oats? If so, yes! The texture will be a little more dense and chewy, but still delicious! Hope this helps! Enjoy! ❤️

  8. Always searching for a good GF recipe that my husband can enjoy with us. My whole family loved these. I only had old fashion oats on hand so that’s what I used.
    Curious to know what changes by using the quick cooking oats?






    1. Hi, Mari! Yay! I’m so happy y’all enjoyed them. The quick cooking vs old fashioned oats is simply a matter of texture preference. You would have gotten a chewier bite with old fashioned oat. The texture is just a little bit finer with quick cooking, but delicious either way! Hope this helps. Enjoy!❤️

  9. I am an avid baker and almost all recipes work out for me, but this recipe is not good. It is far too sweet and both my husband and I love sweet treats. The texture was also really off. If the sugar was lessened, omitted the crumble and the oats pulsed for the base…it might have been okay. Sorry, but I would not recommend even trying this recipe.






    1. Hi Crystal! Thanks for your feedback and opinion. It sounds like this just isn’t the recipe for y’all as there are a lot of people out there that make and enjoy these bars often, including myself.

  10. hi there! I am Type 1 diabetic momma. I was wondering what the nutrition values and serving size are in this recipe. My T1d son is super picky and I would love to make these for him. So if it isn’t too much could you please post them for me.

      1. Hi, Miriam! YES! The texture is just a little bit finer with quick cooking, so expect it to be a bit chewier with old fashioned, but delicious either way! Hope this helps. Enjoy!❤️

  11. OMG these bars made my house so….. wonderful when I was baking them. I made them for the P.T. staff where I go, I know they will love them. Thank you so much for sharing you recipes.🤗💕🤤❤️






  12. Just made these today! Very good, but I only tried it warm so far. The taste is wonderful. I did sub rolled oats ( pulsed in a blender twice as mentioned in previous comments) and sub apple sauce for oil… It came out so good! Thank you.






  13. these are super yummy! I used dark chocolate chips in the batter and left out the added chocolate chips in the streusel topping, which I found to be perfect for my taste. I think sweeter chips would have made it too sweet for my liking. I also added coconut flakes in the batter, which turned out so good!






    1. Hi, Estrela! Yes! You may need to adjust the salt or sugar to your taste, if your peanut butter is unsalted and unsweetened.

  14. I make these A LOT! We make them in muffin cups and they are a quick and easy breakfast.






    1. I’m so happy to hear, Elizabeth! I love the idea of baking the recipe in muffin cups. Perfect portions. Thanks for sharing!

  15. Made these just to use up some overly ripe banana’s and I have to say they were amazing…..I used a bit more banana then mentioned as it would have been wasted and even though it needed longer bake time it was worth it (just like the l’oreal ad) ! I scoffed 2 chunks with fresh cream drizzled on top OH MY what a treat……amazing. Thank you 😘😘😘






  16. I love this recipe! I’ve made it twice in the last month. Curious if anyone has tried it in muffins? Maybe grinding the oats would help them hold together?






  17. Absolutely delicious and not as sweet as I imagined them to be. I made half a batch and that was the perfect amount for myself and a sick friend. Changes I made were: add a dash of cinnamon and blitz a 1/4 of the oats to make a flour so they would hold their shape a little better (after reading some of the comments). I will be making these again and again!

  18. Wow! I really enjoyed this recipe. I made it over the holidays and froze half. I just finished the frozen half today. Thank you for such a delicious recipe.






    1. Yay! So happy to hear. And thanks for letting us know how great it freezes. I hope you continue to enjoy!

  19. Made this delicious treat this morning! Yummy. Thanks for a great recipe. I purchased a cheap bag of bananas and came across you recipe and thought about if for several days, while those yellow treats turned a bit more brown. I am glad I went with this recipe. Hoping it freezes well, as I am the only one eating it. My husband doesn’t like banana or oatmeal. More for me!






  20. I made this for my grandkids! Not only did they love it but their parents did as well! I did add a hint of cinnamon. Thank you so much for sharing this recipe. Perfectly moist, great flavor!






  21. These are the best bars I’ve ever had! I can’t even tell you how many times I’ve searched for recipes to use up older bananas and this pops up every time…no matter how many times I say “nope! ur gonna try something new!”, it never fails…these r coming out of my oven within an hour !!! So easy and so delicious! Thank you for sharing this recipe!!






  22. These came out really good. Great tasting. My only problem was I cannot cut them into squares because they’re not firm enough. You’d have to scoop them out and put them in a bowl but otherwise they’re very tasty. Would taste great with a scoop of ice cream on top.
    I post a picture but I’m not sure how to do that.






  23. I made these today for the first time, they were a hit! I followed the recipe exactly and also added a sprinkle of cinnamon. Deeelish! I wouldn’t mind trying regular oats for a more chewy texture some time. The recipe is a keeper!






    1. Hi Ann! I don’t provide nutritional information at this time because everyone uses different brands of ingredients which often have differing nutritional values. I would recommend plugging the ingredients you use into a free online nutrition calculator like: http://www.myfitnesspal.com/recipe/calculator Hope this helps. Enjoy!

  24. They are excellent !! Healthier, moist and sweet (but not too sweet) – best of all worlds! Yum!!






    1. Hi Tiffany! You could use applesauce, but I would recommend only using 1 cup to replace the mashed banana. Hope this helps. Enjoy!

  25. These are really great. They didn’t come out exactly as I expected, to be honest, but they were still very good. The texture of the “bread” part was definitely more moist and soft than I thought it would be and had a distinct buttery flavor. If you don’t expect the bars to come out like bread, and more like soft oatmeal bars, you’ll love them. They’re not too sweet either with great flavor.






  26. Just made these, they are delicious! Followed the recipe exactly except added some chopped peanuts to the crumble.Yum!!!

  27. I love these!!! I used whole oats (that’s all I had). It did need a few more minutes to cook but texted is great. It’s in between a granola bar and bread. PERFECT! I also used coconut sugar and I liked it. I was just experimenting. LOL Love your recipes!






    1. Hi Louie! Absolutely! I only use natural peanut butter. Just make sure you stir the oil in really well so it’s not thick or dried out before using it. I use the creamy no-stir natural peanut butter for all of my baking. Enjoy!

  28. This is the greatest baked oatmeal I’ve ever had!!! I added some coconut flakes to the streusal and it was fantastic!!!! I will for sure be making it again

  29. The Best Banana Bars Ever! This will definite my new go-to Banana bar recipe. Thank you so much for sharing!!






    1. Hi Sara! If you’re going to enjoy it within a few days, you can store it covered at room temperature. Otherwise, I would recommend storing it in the refrigerator for up to about 5 days. Enjoy!

  30. I was definitely excited to try this recipe just for something different from traditional banana bread. I noticed there was no salt in the recipe so I added 1/2 teaspoon. The bars smell great out of the oven but I was disappointed with the taste/texture. I want to make this again except I will add flour to the bread batter and not oats. Maybe it was a texture issue for me with the oats. The streusel topping is delicious.






  31. I tried this recipe for first time and realized after about 20 minutes i looked at recipe again and i thought it was for bread. Didnt catch that it said banana bread bars!! Took out of oven and put it in 9×13 dish and put vack in oven. Going to have to watch the timing. Will let you know if i was able to save it in time!!

  32. These are delicious! Perfect amount of sweetness (read, not too sweet) and perfect amount of chocolate and crunch as well. Thank you!






  33. This recipe made my kitchen smell like peanut butter Heaven! The inside of the bars are super gooey and moist (I think because of the bananas), and the peanut butter is soo creamy 😋. I was thinking maybe I could put some coconut in the streusel for some extra chew/flavor but maybe I’ll try that next time:)






    1. Hi Jenel! Yes, but the texture will be a bit chewier and might take a little longer to bake. I like using quick cooking oats for this recipe because they bake with a more uniform texture that is bread-like. The old-fashioned oats will give you more of a chewy granola bar texture. You can use a food processor or blender to pulse the old-fashioned oats a few times to give them the texture of quick cooking oats. Hope this helps. Enjoy!

  34. Oh my goodness, you are so right! I adapted the recipe from another banana bread recipe that used flour. Thank you so much for catching this. There’s no flour in the bars – I meant to put oats in its place. I am curious to hear how your bars turn out!

    1. They didn’t turn out! Fell apart when taking out of the pan…following the recipe exactly. I feel they need some flour to hold them together.

      1. Hi Emma! I’m sorry to hear they didn’t hold together for you. What type/brand of peanut butter did you use? Did you use quick cooking oats? Where your bananas ripe and did you measure them to 1 and 1/2 cups? We bake these all the time and have never had the issue with them falling apart because they are just so moist. I hope you’re able to try them again with better results.
