Choosing Ripe Bananas

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. 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.

  2. 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.

  3. 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.🤗💕🤤❤️

  4. 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.

  5. 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.

  6. 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!
