    can i substitute a nut butter for the protein powder?

    • replied:

      Hmm I think the texture will turn out differently!

  • says:

    These look delicious! Can I substitute almond flour or ground flaxseed for oat bran? Any other suggestions?

    • replied:

      I haven’t tried it so I’m not sure how it will turn out! Feel free to use almond flour in these muffins instead 🙂

    I am currently addicted to these muffins! I had a ton of oat bran around because I used to use it to make overnight oats. These remind me of overnight oats but so so so much better and more fun to eat.
    My protein powder is not vanilla and it is unsweetened- so I do add a few drops of liquid monk fruit depending on the flavor of my bananas. Ripe bananas can be super sweet or just average and blah so I taste as I go and decide.
    My favorite add in so far are mini frozen blueberries! Adds extra moisture and natural sweetness. And I take take the liberty of sprinkling a little of that chunky baking sugar on top before baking so they feel like a bakery treat.
    I like them warm but I also like them just as well cool from storing in the fridge. I have not needed to add any spread to enjoy when I use enough bananas and they are super moist. If I don’t have quite enough they are a bit drier so a little butter or peanut butter is nice.
    Now I am wondering if there are any substitutes for the bananas because I want to eat them all the time and don’t always have ripe bananas hanging around. This is a very healthy AND yummy recipe! Thank you.

      Amazing! So glad you love these ones 🙂 I haven’t tested these using an alternative to bananas, so I’m not 100% sure.

    Are you able to use oats instead of oat bran?

    I thought these muffins were very good! That being said, I changed the applesauce for oil because I didn’t have any applesauce. I also added a touch of salt, and I’m glad I did because there wasn’t a whole lot of flavor going on, so you really need the salt to help the flavors out. Also, these are tasty if you are expecting a “healthy” muffin. These don’t taste like cupcakes or a muffin you would get from a bakery. They are perfect in the morning with a little salted butter and a drizzle of maple syrup!

    • replied:

      Happy they turned out great! And good idea to add the salt to boost the flavor 🙂 Thanks so much for the review!

  • says:

    WOW!!! Super impressed with this recipe. Measured 230 g oat bran (Bobs Red Mill). 200 g is 1 2/3 cups. Extra 30 g to replace protein powder. Added heaping tsp cinnamon, few sprinkles nutmeg and toasted whole walnuts. Filled 11 cupcake liners. Baked 375 18 minutes.
    Served warmed with sliced bananas and drizzled with honey. Yum!! Yum!! Yum!!
    Thank you!! I wanted to find a healthy dessert and this is it. Even my husband who is a foodie loved them. Saving your recipe!!

      Thanks for sharing, Denise! I’m so happy you and your husband both loved these 🙂

    Nope, these were gross. I think there needs to be a fat, either oil or but butter. There could also be more salt. Oat bran? Who can find that?! I figured I had oat flour and oats so I did 1 cup oat flour and 2/3 cup oats. And the flavor was gross. Won’t be trying these again

    • replied:

      Sorry you didn’t enjoy these!

  • says:

    What brand vanilla protein powder did you use? There are so many and some are really sugary or have sugar alcohol.

    • replied:

      I love Aloha! Here’s the one I often use 🙂

    Followed recipe exactly and they turned out great. Very tasty and satisfying for the number of calories. I added dark chocolate chip morsels to half the batch and wow did that take them to a whole other level!

    • replied:

      Perfect! Glad you loved them!

    This is my favorite “healthy” muffin recipe now! Oat bran works so much better than other oat flour recipes I’ve tried since those get gummy. Question – for a pumpkin version, do you think just substituting 1/2 cup pumpkin puree instead of the applesauce is enough for pumpkin flavor? Or should I maybe replace 1 banana with some pumpkin too? I didn’t want to lose the sweetness from the bananas. Thanks!

  • says:

    Not knowing what oat bran is, I just accidentally bought Kellogg’s Cracklings Oat Bran cereal because that is all that showed up on my grocery store’s app.
    16 grams of sugar per serving. Whoops.
    Now order Bob’s Red Mill version from amazon. 🤷🏻‍♀️

    • replied:

      Shoot! Sorry about that! Let me know if you end up giving them a try with the oat brand 🙂

  • Hi can you use almond meal or whole wheat flour instead of bran? Or rolled oats? Thanks

    • replied:

      I haven’t tried it, but oat flour may work well!

  • says:

    Okay, so intrigued by these. Oat bran?? I’ve never even thought of using that, but it sounds way good (what’s not good from Trader Joes though, right?). I usually make protein muffins from boxed mix – https://shop.kodiakcakes.com/collections/muffins. But, since many of us have been home quite a bit more lately, I have been baking a lot – especially from scratch. My question is, do you feel like your muffins rise in the oven as much as muffins with flour do?

    • replied:

      Love that idea! And they won’t be quite as fluffy as regular flour, but still delicious 🙂

  • says:

    such a good snack

  • says:

    Wow! Absolutely loved it Monique. Will certainly be baking it again. Perfect healthy muffin with all the protein trimmings :-). I used plant based protein powder with no flavour but was still delicious xx

    • replied:

      The perfect snack! Glad you enjoyed 🙂

    This recipe is amazing!! So hard to find good healthy snacks recipe but this one is perfect! I reduced the amount of oat bran and doubled the protein powder to make the perfect high protein snack. Some chocolate chips and they came out sweet and moist. Hard to only eat one!
    Thank you for the recipe!!

      So glad you liked them recipe 🙂

    I made these with rolled oats instead of oat bran since I didn’t have any and I used a vanilla casein protein powder. They turned out so yummy!! I gave each of them different toppings for fun: blueberry and coconut, raspberry and peanut, chocolate and almond, and raisin and pumpkin seed. I love all of them! Thank you so much!!

    • replied:

      Amazing! Love the idea of different toppings 🙂 glad you loved them all!

  • says:

    Add 1 tsp salt. Thank me later.

  • says:

    These look awesome! Quick question… is the protein powder you use sweetened? Mine is sweetened with stevia, not sure if that would affect the taste at all? Thanks!

    • replied:

      It’s usually sweetened a bit (the one I like has a bit of coconut sugar). It will just make these a little sweeter, but not too sweet.

    Sounds delicious 😋 but I wouldn’t called them protein muffins as it yields 17.3 g of carbs and only 6.3 g of protein per muffin.

  • says:

    Can you tell me the brand of vanilla protein powder you used to make the muffins? Looking forward to making them.

    • replied:

      I usually use Aloha protein powder! Enjoy 🙂

    I accidentally forgot the egg and these still turned out really well. The flavor is great. Obviously the consistency would have been better if I hadn’t of forgotten the egg, but I could still tell it’s a good recipe!

    • replied:

      5 stars
      Glad you enjoyed regardless!

  • says:

    I made these and they were good but a little ‘too’ moist.

    Can you suggest a way to make them a little more dry? Cook them longer? Add/Lesten one of the ingredients?

  • says:

    Hi Monique, excited to try this and wondering if you think I can sub collagen for the protein powder?

  • says:

    Made these today and they are BOMB! I used quick cooking oats instead of oat bran(lightly blended the oats into a semi-flour before mixing) and olive oil cuz I don’t have applesauce. I added mini choc chips to the batter before baking. Didn’t expect them to be this good! Thank you!

    • replied:

      Perfect! Mini chocolate chips sound amazing in here – definitely adding those next time. Glad you enjoyed!
