Banana peanut butter oat muffins are healthy, delicious, and simple to make.   All of the ingredients get pulverized in a food processor, or blender.  This breaks down most of the oats and produces a smooth batter.  It also makes the mixing process a cinch.

There is no flour or oil in this recipe.  The oil is replaced with fat free Greek yogurt.  However, there may be some oil in your peanut butter, depending on what kind you buy.

These muffins are a perfect breakfast to make ahead for grab-and-go breakfasts throughout the busy work week.  Just store them in an airtight container in the refrigerator for up to 7 days.  Or, place them in the freezer in freezer-safe storage bags.  Then, transfer individual muffins to the refrigerator the night before you want to eat them.

  1. Delicious- and I even forgot to add the sugar! I’m going out to buy more oats this morning to make more to take to a friend. Will probably add the sugar this time LOL

    These put the “muff” in Muffin. They are just lovely, wait about 5 mins after out of oven with a dab of butter. So easy to prepare, and just the right blend of ingredients. I added one item to them to test the waters and it was wonderful. Great JOB and top of the muffin to you.

  3. 5 stars
    These are yummy. The family loved them. Also very fast and easy to put together. I added raisins and nuts.

  4. Loved this recipe, though I substituted sour cream and almond flavoring for the yogurt and vanilla. I also added chopped dried apricots. Delicious muffins.. could also ad raisins or chopped apples.👏

    Scrumptious, 3 bananas, 1 egg, 3 tablespoon of honey, no sugar, no salt oops I forgot the salt. I have a mini-chopper put in the large oats to grind added in bowl with dry ingredients. In chopper whipped the bananas then added the wet ingredients and with a spoon mixed everything. The yogurt was vanilla flavoured so no vanilla added. Also the bananas weren’t fully ripped.

    Hi Amanda – I just made the muffins – they are great, with a very light and fluffy texture!

    I used tahini instead of peanut butter, included lemon zest and a 1/2 teaspoon of cinnamon, and did not include any sugar. Next time I might try the muffins with a 1/4 cup brown sugar.

    Thanks for the recipe, it is definitely a keeper, and will be made often!

    I made this over the weekend with a couple of modifications:
    1. Regular homemade yogurt instead of greek yogurt because that’s what I had on hand
    2. Brown sugar instead of regular

    This is such a winner! I’m totally enjoying the subtle sweetness from the bananas and the saltiness from the peanut butter. I also love the texture that the tiny grains of oatmeal add.

    I just ate one for breakfast and am kicking myself for not bringing 2!

  8. ok made this and doubled the recipe. didn’t have yogurt so used sour cream and some lemon juice and mayo and milk and only used 1 cup total… also added some protein powder… made in a 9×13 cake pan baked at 350 for 30 minutes and it was wonderful…. will make this again best cake gluten free texture ever…. thanks for the wonderful recipe.

  9. I wanted to put these in my weight watchers list but I need to know the grams of sugar to get points value. Does anyone have this?

    These are AMAZING. I’ve made quite a few times. Blending everything gives it the consistency of “normal” muffins (not the weird texture of oat muffins). I typically throw over ripe (peeled) bananas in the freezer, and they work perfectly for this recipe. I’ve made these into mini muffins and full sized muffins. They are also good with a few chocolate chips sprinkled in (although I wouldn’t use a ton, or you over power the peanut butter & banana flavor). 2 thumbs up!

        I also loved them
        I used Better N Peanut butter it’s less fat then regular peanut butter and added tiny bit of walnuts and ch chips

    Just made a double batch of these and they are delicious! I added some chocolate chips. Into the freezer they go for an easy breakfast. Thanks loving the oat flour recipes!

    This is a great recipe and they turned out very tasty! Thank you! The only problem I had was that they were nice and round and deflated after a few minutes out at room temperature. Did I do something wrong?

  13. 5 stars
    Thank you! I have tried this recipe a couple of times and it we enjoy them.
    This past time I took out 2 TBS of oat flour and adding 3 and 1/2 TBS almond flour.
    I used coconut oil instead of almond butter.
    I used date sugar instead of sugar.
    I used whole milk yogurt instead of greek (this I was very nervous about)…and it was little more moist and tasty!!!
    Thank you again for sharing!

  14. 5 stars
    Great recipe!! Simple and satisfying!
    Thank you very much for sharing!
    I used maple syrup instead of brown sugar and next time I will attempt with dates instead.

  15. I made these muffins but forgot to put them in the fridge. Is it required? I wasn’t sure since it had yogurt in them. 🙁

  16. 5 stars
    just made these, I added 3 scoops of protein (protein 17) to mine! they turned out great. but seems if I would not have put my protein in, they would have turned out to mushy. but either way would have been delicious, I couldn’t stop eating the batter

  17. Sounds really yummy? Have you ever tried a substitute for the sugar? I’d love to make these for my toddler but without the sugar… Any suggestions would be awesome. Thx!

    1. Abby,
      I haven’t made them without the sugar. But, I believe that substituting natural sweeteners, such as honey, agave, or maple syrup, would work just fine.
      Hope you like them!

      Family really liked these muffins. I skipped the sugar because I figured the bananas and peanut butter had enough to sweeten them and I was right. I had chocolate chips to half of them for the kids. Great and healthy recipe for a quick snack.

      One question-how long are these good for and do they need to be refrigerated? Thanks!

  18. I love your recipes! You are my go-to source for healthy yet delicious food. I was wondering if you thought these could be made with cashew butter instead, since my husband has a peanut allergy. I wasn’t sure if the composition of nut butters was similar enough to replace one another when doing something as exact as baking. What do you think? I might give it a try.

    1. Britton,
      Thank you so much!!
      Yes. You could easily switch out the peanut butter in this recipe for other nut butters, like cashew or almond butter, using the same measurements.
      Hope you like it!

  19. I love this recipe! I have some banana’s ready to bake up and it will be a nice change from banana bread.
