What Do I Need to Make Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars?
- Unsalted butter, softened
- Creamy or crunchy peanut butter
- Light brown sugar
- Vanilla
- Eggs
- Quick-cooking oats
- Baking powder
- Baking soda
- Mashed ripe bananas
- Chocolate chips

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.

Notes
In this recipe, peanut butter can be substituted with almond butter or cookie butter.
I made this today, it’s delicious!!! It’s a hit with the whole family.
They are excellent !! Healthier, moist and sweet (but not too sweet) – best of all worlds! Yum!!
Can I substitute the bananas for something else beside Pumpkin Puree?
Hi Tiffany! You could use applesauce, but I would recommend only using 1 cup to replace the mashed banana. Hope this helps. Enjoy!
These look delicious. I should keep these on hand for breakfast.
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.
Just made these, they are delicious! Followed the recipe exactly except added some chopped peanuts to the crumble.Yum!!!
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!
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!
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
Healthy enough for breakfast? 😍😬
