Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars

Jump to Recipe

When life hands you overripe bananas, bake up some Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars with Peanut Butter Oat Streusel. Whew, that’s a mouthful! A delicious, chewy, chocolatey mouthful.

No Such Thing as a Bad Banana

I cannot even look at these photos without my mouth watering. Friends, these banana bread bars are everything. They’re sweet, chewy, dense, and y’all, I’m not even over here pretending they are a healthier version of anything 😂. Made with butter, brown sugar, and lots and lots of love, they disappear as fast as you can serve them up.

It all began one morning with a bunch of very ripe bananas. Never one to let a squishy banana go to waste, I decided to whip up something new. Something dreamy. And these Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars with a Peanut Butter Oat Streusel are a dream come true!

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.

Banana Bread Bar Batter (Say THAT Three Times Fast!)

To make the batter, first, cream the butter, 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 the vanilla.

In a separate bowl, whisk together the oats, baking powder, and baking soda. Next, add the oat mixture to the ingredients in the stand mixer and beat on low to medium speed until well combined. Finally, fold in the mashed banana and then 1 cup of chocolate chips.

Streusel, Bake, Eat

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 pan, sprinkle the streusel evenly over the batter. There you have it!

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

I admit that waiting for these beauties to bake requires a lot of patience. And letting them cool for 15 minutes feels like a Herculean task. But I promise they’re worth the wait!

Finally, once cooled at least 15 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!”

Craving some more sweet banana inspiration? Try this Classic Banana Bread or one of my flourless banana bread recipes which are all easily made in the blender with minimal ingredients. You’d never believe they don’t have any flour, butter, oil or granulated sugar in them.

I hope you and your loved ones enjoy these Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars as much as we do. When you make them, be sure to snap a picture and tag me on Instagram @thebakermama so I can see! 😍 I just love seeing how inspired and creative y’all get with the recipes and ideas I share.

xoxo,

    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!

    Could you substitute old fashion oats instead of quick cooking oats?

      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!

    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:)

      Hi there! You can always sub pumpkin puree for the banana, if you choose. Enjoy!

    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!!

    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.

      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!

    This looks awesome! Can natural peanut butter be used as a substitution? Has anyone tried?

      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!

    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!

    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.

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