Oatmeal Banana Peanut Butter Muffins

April 21, 2020

Extra-ripe bananas and all-natural peanut butter make these oatmeal banana peanut butter muffins a healthier snack option! Made in one bowl and no added sugar, these muffins will become a must-bake healthy treat!

This recipe came about when I opened up my freezer and found 12 overripe bananas. #truestory Since I already perfected banana bread (which is my usual go-to), I decided to change it up and experiment with one of my favorite flavor combinations: peanut butter + banana.  

Think banana bread meets oatmeal meets peanut butter. It really doesn’t get any better than this these Oatmeal Banana Peanut Butter Muffins! Once you save up enough ripe bananas, you just need pantry staples to make these delicious muffins. 

Ingredients You Need:

  • oat flour – you can easily make your own by grinding rolled oats if you don’t have oat flour on hand!
  • baking powder
  • baking soda
  • sea salt
  • VERY ripe bananas – I’m talking black, mushy bananas!
  • vanilla extract
  • egg
  • peanut butter – I like to look for an all natural version where the ingredients are just peanuts and salt.
  • unsweetened almond milk

No Sugar Added!

Did you notice that sugar isn’t on the ingredient list? The ripe bananas add enough sweetness for these banana peanut butter muffins… you just have to make sure they are super ripe. Bananas that aren’t quite ready are more tart while bananas that look like they should be thrown away are actually almost caramelized and perfect for these muffins! If you like things on the sweeter side you can add some coconut sugar.

Making and Storing These Muffins

To store these muffins: you’ll want to make sure they’re completely cool first. Allow them to cool in the muffin tin for 20 minutes before moving them to a wire rack to completely cool. Store in an airtight container at room temperature for up to three days or in the freezer for up to three months.

    Just made these and am trying not to eat them all now! I didn’t have oat flour so I replaced it with 1c. Whole wheat flour and 1/2 c each almond and coconut flours. Turned out perfectly and so quick to prep!!! My toddler likes them too and she doesn’t even like bananas. This will be my new go to recipe since I’m cutting sugar and all sweeteners from my diet. Thank you!!!

    Hi Davida,

    I’ve made and love so many of your recipes! Of all the foodie bloggers I follow, your recipes are the most consistently reliable and delicious. What a wicked last name BTW! Have you come up with a kugel recipe? There are so many kugel variations even within my family alone.

    These muffins are currently in the oven but I was all out of peanut butter so I used cashew butter. Substitutions are like a pet peeve for me but I made an exception during a hangry emergency. Thanks and keep rocking it xo

      Hi Natalie! Sorry for the delay in responding, I’ve been on the road for a few weeks! I haven’t come up with a kugel recipe as my mom’s peach kugel might be the ultimate and hard to top 😉 I hope you enjoyed the muffins. I love that recipe!

    Is oat flour just blitzed porridge oatlets? I live in Ireland and have never seen oat flour but have baked with oats. Many thanks.

    I love September and am always hit with back to school nostalgia, I’m the kid who loved going back to school, when classes started and it was time to buy new pens and notebooks and all those great staples!! 😀

    I love the combination of banana+peanut butter+oats, can’t wait to try these! Just so I know what to expect: are these dense, rather chewy and moist kind of muffins?

      Is it weird if I say they’re dense, chewy and moist? I find when they’re dense they’re pretty chewy and moist and when they’re lighter they’re fluffier and drier? But that’s just me!

        Not at all weird, that’s how I meant to ask as well: dense-chewy-moist go hand in hand usually with muffins that aren’t fluffy, airy and light. So I got it, thanks! 🙂
