Three peanut butter oatmeal chocolate chip bars stacked on top of each other. Next to them are some crumbs and 2 more pieces off to the side.

They make an easy throw-together snack or dessert when you are craving something sweet, but still want to keep it healthy. The macronutrient ratio is excellent and they have a good balance of carbs, healthy fats, and fiber, and each one has 7 grams of protein!

I’ve been loving them as a snack or dessert. Enjoy them warm or cold. Once cooled, they get a little firmer and take on a dense and chewy texture and it tastes like a big fat oatmeal cookie. If you really want to do it up, warm one up and top it with some ice cream! Michael did it the other night and the combo is epic!

Why we love these oatmeal chocolate chip bars

  • absolutely delicious – especially out of the oven when they are a little bit warm
  • made in one bowl
  • simple whole food ingredients – and I’m guessing you probably already have most of the ingredients at home.
  • lightly sweetened – we are using just a tablespoon of maple syrup + brown bananas.
  • super customizable – you can easily adjust this recipe to what you have on hand and change up the flavors each week.

Ingredients

  • spotted or brown bananas – the browner, the sweeter the recipe will be!
  • peanut butter – look for a drippy and all-natural variety
  • milk – any kind will work!
  • maple syrup – just a touch a little added sweetness
  • pure vanilla extract
  • rolled oats
  • ground cinnamon
  • baking powder
  • salt
  • chocolate chips

How to make peanut butter oatmeal chocolate chip bars

  1. Preheat oven to 350 degrees Fahrenheit and grease an 8×8 square baking pan.
  2. Mix together wet ingredients. Add bananas to a large bowl and mash with a fork until no lumps remain. Next, add in peanut butter, milk, maple syrup, and vanilla extract and mix until well combined.
  3. Stir in dry ingredients. Add oats, cinnamon, baking powder, and salt and stir until incorporated. Finally, fold in the chocolate chips. The batter should be somewhat wet (see photos above).
  4. Bake. Pour the mixture into the greased baking dish, spreading out evenly. If desired, sprinkle with a few more chocolate chips. Bake for 25-30 minutes until golden brown on the top and a toothpick comes out clean.
  5. Enjoy! Let cool and enjoy!

Storage

  • fridge – first, let the bars cool completely. Add to a sealable airtight container or cover your baking dish with saran wrap. Store leftovers in the fridge for up to a week. You can also leave them on the counter at room temperature, but only if your house is not too hot. I would only do this for 1-2 days.
  • to freeze – let cool completely and place individual bars on a large plate or baking sheet lined with parchment paper. Place in the freezer and let freeze for 2 hours or until hardened. This will help ensure they freeze individually and won’t stick together. Transfer to a large bag (we love reusable silicone ones) and freeze for up to 3 months. You can defrost them by placing them in the refrigerator and then warming up the microwave if desired.
  • reheat – these can be eaten hot or cold! To warm up, pop them in the microwave for 15-30 seconds until warm.

Substitutions and additions

These peanut butter oatmeal chocolate chip bars are great as is, but you can definitely change it up to keep it interesting. Here are a few suggestions:

  • spotted or brown bananas – if you don’t have enough bananas, you can use some applesauce or pumpkin puree to make up the difference. This will change the flavor some.
  • peanut butter – any kind of nut butter will work. Try tahini or sunflower seed butter to keep them nut free.
  • milk – any kind of milk will work (almond milk, oat milk, or dairy milk).
  • maple syrup – any kind of liquid sweetener will work (honey, agave…). You can also leave it out if you don’t want any sweetener.
  • rolled oats – quick oats will work instead of rolled oats. Steel-cut oats will not work as the texture is different. Use certified gluten-free oats if needed.
  • baking powder – baking soda will work instead.
  • chocolate chips – milk, semi-sweet, dark chocolate chips, chocolate chunks, or white chocolate chips will work. Use dairy-free if needed.

And here are a few additions you can add to spice them up:

  • more peanut butter – these have a slight peanut butter flavor, but if you love it, feel free to add more.
  • chopped nuts – walnuts, peanuts, or pecans would be great.
  • fresh or dried fruit – strawberries, raspberries, blueberries, or cranberries would all be great – kind of like a PB&J!
  • shredded coconut – chocolate and coconut are always a good idea.
  • protein powder – for a little extra protein boost, you can add a scoop or two of your favorite protein powder. I would suggest adding a little more milk to ensure they aren’t too dry.
  • cacao powder – to make them extra chocolatey, stir some cacao powder to the batter.

    These are great! I subbed 1 cup of unsweetened applesauce for the bananas and it was a great sub. I just added a few more oats and it all came together. Thanks for the treat!

  2. 5 stars
    Love these! Made these a couple times and they came out super dry last time…any suggestions to make them more moist? I even added less oats

    1. So weird they come out dry for you! I find they are super moist. I would make sure you are using enough bananas (should be 200 grams). You can add more milk as well to help keep them from drying out. The batter should be pretty wet once it is all mixed. Let me know if that helps!

      1. Thank you!! Turns out I needed more milk and now they’re perfect:) one of my favorite recipes!!

    LOVE THESE BARS and even better, so do my kids! Can’t beat 7g of protein per bar and all whole ingredients. These are in our rotation for meal prep!

  4. 5 stars
    These are my go to snack! I cut them in 16 portions (instead of 9) and use them for a snack or a carb with a lite meal. They freeze great… I may or may not have eaten them straight from the freezer!

    I added some walnuts on the second batch. Yum! These are a family staple now. Just waiting for my bananas to get brown enough before I make another batch!
