Peanut Butter Banana Chocolate Oatmeal Bars

These are, without a doubt, my FAVORITE healthy snack recipe ever!

Peanut Butter Banana Chocolate Chip Oatmeal Bars

Peanut Butter Banana Chocolate Chip Oatmeal Bars

It is the super ripe bananas that make these bars so incredibly soft. Super ripe bananas are super-brown and super-sweet. The natural sweetness of the ripe bananas also lessens the brown sugar needed in these bars, which is always a good thing in my book.

The more ripe your bananas are, the better these bars will taste. And the softer they will be, too.

The peanut butter packs a HUGE flavor punch and the oats give these bars a nice chewy texture. The chocolate chips and peanut butter chips bring it all together. And these bars are so easy to make. When it comes to healthy recipes, simple  and quick are the most important to me.

Peanut Butter Banana Chocolate Chip Oatmeal Bars

I loathe long bake times, complicated recipes, and slaving away in the kitchen.

There’s none of that in these bars. Just mix everything up in 1 bowl and 20 minutes later you’ll be snacking away.

Simple, quick, and healthy peanut butter banana chocolate chip oatmeal bars!


  • 2 and 1/2 cups (200g) old-fashioned rolled oats (not instant or quick oats)
  • 1/4 cup (50g) light or dark brown sugar, loosely packed
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 cup (120ml) almond milk (regular or soy milk would be fine)
  • 1 teaspoon pure vanilla extract
  • 1 large egg
  • 2 large very ripe bananas, mashed
  • 1/3 cup (85g) creamy peanut butter
  • 1/2 cup (90g) semi-sweet chocolate chips
  • 1/2 cup (90g) peanut butter chips


  1. Preheat oven to 350°F (177°C). Spray 8×8 square (or 9×9 inch) baking pan with cooking spray or line with parchment paper. Set aside.
  2. Mix together oats, brown sugar, baking powder, salt, and cinnamon. Add in the milk, vanilla, and egg. Mix together until evenly combined. Add mashed bananas, peanut butter, chocolate chips, and peanut butter chips. Stir well.
  3. Pour the mixture into the pan and bake for 20 minutes. Allow to cool and cut into bars.


  1. Make Ahead Instructions: Bars stay fresh for up to one week in a covered container at room temperature or in the refrigerator.
  2. Vegan: These bars can easily be made vegan by using vegan chocolate chips + vegan putter butter chips and using one “flax egg” instead of a regular egg. Flax egg = mix 1 tbsp ground flax with 3 tbsp warm water and let it sit for 10 minutes while it “gels” up. Use the “flax gel” as a replacement for the egg.
  3. Gluten Free: Make sure your oats are certified gluten free to ensure these bars will be gluten free.

  1. Hey Sally, I’ve made these bars a few times and I really love them. My problem is that because I can’t get to grips with cooking in cups, they sometimes come out too dry or too soggy ect. I was wondering if you could put the grams in this recipe? That would be amazing. Thank you 🙂

  2. Sally – I’ve just discovered your blog, and I’ve tried 2 of your recipes this week: pumpkin chocolate bread and these bars. Both of these have been -major- hits with my family. I am not a good cook and I rarely have 1, let alone 2 consecutive successes when trying new recipes! So thank you very much for sharing your talent and beautiful blog, and helping an inept cook like me look like a domestic goddess to my family!

  3. These are so delicious, thanks for sharing. My daughter likes them & consider them healthy with the ingredients in this recipe. I just recently discovered your blog!

  4. Hi! I’m so excited to cook these today, but I was wondering if I could use honey in place of brown sugar? Or maybe half honey, half brown sugar. Also, can I use previously frozen and thawed bananas? I know in your healthy banana bread recipe, you said that wouldn’t be a good idea.
    Thank you!

    1. I would do half honey and half brown sugar. I’m unsure about the frozen bananas here– sorry! Let me know if you try it.

      1. I used previously frozen ripe bananas for the recipe, and it worked out great. I would say to thaw them in the fridge for a few hour or until just thawed in order to avoid extra water from thawing at room temperature.

  5. I honestly didn’t have high expectations for these peanut butter oatmeal banana bars, but I was looking for a healthier way to use up some ripe bananas and decided to give them a try. Boy, was I pleasantly surprised! These are delicious!! My only regret is not doubling the recipe. I can’t guarantee there will be any for the kids when they get home from school! Maybe I’ll just hide the evidence and pretend like I never made them. ssshhh! I’ll definitely bd making these again and again. FYI: I omitted the PB chips because I didn’t have any, and they weren’t missed at all.

  6. Hi Sally!! I’m a beginner baker and your blog has helped me to love baking and to actually bake good stuff! Haha. I especially love your chewy fudgy brownies btw. They’re just heaven!!! I just have a question though, what would happen if i use instant oats in this recipe? 🙂

    1. Hi Jam! Instant or quick oats, which are powdery and thin, will dry these bars out. Best to use thicker cut oats.

  7. These are the best oatmeal bars ever! I, for one, am always searching the comments for substitutions so here are mine: (1) I omitted the sugar and added some liquid stevia instead (to taste), (2) replaced half of the peanut butter with coconut butter (not oil), (3) used just 25 grams of 86 % chocolate, which was plenty of chocolate flavor for me. They worked great with the flax egg. Thank you so much for the recipe, Sally!

  8. Hi Sally! I was just wondering about your thoughts on using all natural peanut butter in this recipe, which would maybe require a slight increase in sugar? Love following your blog by the way! 

  9. I was wondering about how many calories are in these bars. Planning on taking them to work for our healthy snack days but need to be able to let the ladies know about the calorie count. Can you help me out?

  10. Please could you tell me what are “Peanut Butter Chips” maybe I would know them under a different name,I am from Cornwall in Southern UK , this recipe really sounds Yummy !!!  June X

    1. Hi June!
      Peanut butter chips are basically chocolate chips but made out of peanut butter instead of chocolate!

  11. If I am making this and freezing it should I mix, bake, and freeze or should I just mix it all, pour into my pan, and then freeze (thawing before baking when I take out to use)??

  12. I made these with a “flax egg” and substituted in pure Almond Butter amd Raisins and dried Cranberries instead of the chocolate chips and  PB chips, turned out great especially for my friend who don’t eat egg or chocolate! Thanks for the tips in your recipes – very helpful! By the way the link in paragraph one you referred to your first “Peanut Butter Banana Oatmeal bars” isn’t working. Only thing wasn’t unclear to me in the recipe was when taking it out of the oven if to let it cool in the pan  for a while or immediately turn it out onto the wire rack. 

  13. These are delicious, I make these almost every other week, another amazing recipe from Sally! Instead of making them into bars, I drop them on to a cookie sheet to make these delicious to-go balls — the perfect mid-workday snack. Thanks, Sally!

  14. Hi- the link to your old peanut butter and banana bars recipe simply redirects to this page… If I want to make these without using the chocolate or peanut butter chips, do I need to make any adjustments? Thanks!

  15. I can’t stop making these! Quick, easy, delicious…amazing!

    We live in Saudi Arabia and I have a zillion bananas growing in my backyard – I’m sneaking three or four bananas into this recipe and making it a bit too gooey but still, yum! A smooshed up banana, fresh from the hot sun, part coconut milk, and gooey oats (also good for breastfeeding Mamas, or so I tell myself while devouring a third or fourth helping!.

  16. Hi Sally! I cant seem to find peanut butter chips in my part of the world and was wondering if you could suggest a different ingredient (as I do not want to replace it with more chocolate chips). Thanks! 🙂

  17. These are perfect! I substituted 2 tbsp of maple syrup instead of sugar. I used quick cooking oats, and left them in the oven for 10 extra minutes. Honestly, they don’t even need a sweetener.
    Delicious – thanks!!!

  18. I haven’t made these in a long time and forgot how yummy they are! I always double the recipe and bake in a 13×9 pan for about 30 minutes. I never have peanut butter chips on hand, so I just skip those and throw in a few extra chocolate chips instead. Easy, delicious and a great way to use up those super ripe bananas.

  19. Hi Sally, I love all your recipes, specially your cakes. First time thought of trying out these bars for my husband who has heart problems and I was very skeptical as to how they would taste, but he totally loved them .. so much that I have been asked to make a double batch next time and also try out all the possible healthy snacks from your site. I only have one question, my bars didn’t get brown from the top like yours are in the picture. Any idea on what I could have done wrong ? I would love it if they looked as good as they taste. Thanks in advance.

    1. Hi Seema, I’m so happy the he enjoyed them! If the bars are the right taste and texture then you didn’t do anything wrong! It’s possible I just left mine in the oven a little longer than you or the lighting in the picture is darker.

  20. So glad you had your website on the bottom of the recipe page. This is a favorite in our house. My husband takes them to work for breakfast. Today I had the windows open and the printed recipe blew to the floor and my dog shredded it. Whew! Found it again and printed it so I can make these tonight. Thank you!

  21. I used up small amounts of chocolate, peanut butter and butterscotch chips – delicious! Just the right amount of liquid ingredients for great texture.

  22. These are amazing, Sally! I have made them several times recently and they get devoured quickly. This is a top recipe for me!
