Soft, Sweet, and Full of PB Goodness!

After how much you all loved my Chocolate Peanut Butter Muffins, I had to share this banana version. No chocolate this time, just all the peanut butter banana goodness. I have a bunch of banana recipes on the site (some lighter, some more indulgent), but these are the first ones to really bring bananas and peanut butter together in such a crave-worthy way.

If you’re into bananas, peanut butter, oats, and dark chocolate (yep, I still snuck a little in), these muffins are right up your alley!

Ingredients In Peanut Butter Banana Muffins

  • Overripe Banana: Use overripe for the best flavor and texture.
  • Peanut Butter: Replaces the need for oil or butter. Use creamy (not natural or runny).
  • Honey & Brown Sugar: You can adjust the brown sugar for more or less sweetness.
  • Vanilla Extract & Salt: Boosts overall flavor. Salt balances the sweetness.
  • Egg: Binds everything together and gives the muffins structure.
  • Baking Soda & Baking Powder: Helps the muffins rise and keeps them fluffy.
  • Oat Flour: Blend your own oat flour for best results and measure after blending.
  • Dark Chocolate Chips: Sub with milk or semi-sweet chips if preferred, or leave out.
Wet ingredients being added to dry ingredients, mixed together, and then poured into prepared tins for baking.

How To Make Peanut Butter Banana Muffins

  1. Preheat oven and grease muffin tin.
  2. Mash banana and mix with peanut butter, honey, vanilla, brown sugar, and egg.
  3. Blend oats to make oat flour.
  4. Add salt, baking soda, baking powder, oat flour, oats, and chocolate chips to the mixture.
  5. Scoop into muffin tin and bake until set.
  6. Cool in tin, then transfer to a rack. Enjoy!

Quick Tip

A good muffin tin makes a world of difference. These tins are my absolute favorite, and I’ve never had a problem with these muffins not releasing well.

Top Tips For Success

  • Mash bananas thoroughly for a smooth texture. Use extra bananas in this Healthy Banana Cake Recipe.
  • Grease the muffin tin well; avoid liners as the batter sticks.
  • Add extra chocolate chips on top for appearance and more flavor.

Storage

Leftover Peanut Butter Banana Muffins

  • Store muffins in an airtight container at room temp for 1–2 days, or in the fridge for up to 1 week.
  • Freeze for up to 3 months. Thaw at room temp or warm in the microwave.

Equipment

Ingredients

  • Cooking spray
  • 1/2 cup overripe banana 1 medium
  • 1/2 cup creamy peanut butter
  • 2 tablespoons honey
  • 1 teaspoon vanilla extract
  • 1/4 cup light brown sugar lightly packed, see note 1
  • 1 large egg
  • 1/4 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/3 cup + 1 tablespoons oat flour old-fashioned oats that have been blended in the blender
  • 1/3 cup old-fashioned oats see note 2
  • 1/3 cup dark chocolate chips can sub milk or semi-sweet chocolate chips

Instructions 

  • Preheat oven to 350°F. Generously spray 8 cavities with cooking spray. Do not use muffin liners; these muffins stick to the liners.
  • Remove the banana peel and mash well with a fork. Measure the banana after it has been thoroughly mashed.
  • In a large bowl, mix together the mashed banana, peanut butter (do not warm up), honey, vanilla extract, brown sugar, and egg. Mix until thoroughly combined.
  • To make the oat flour, pulse oats in a blender or food processor until they have a flour-like consistency. Make sure to measure the oat flour after blending and not before.
  • To the bowl with the wet ingredients, add the salt, baking soda, baking powder, oat flour, old-fashioned oats, and dark chocolate chips. Mix until thoroughly combined.
  • Using a cookie scoop, scoop 2 full scoops of the dough into each muffin cavity, filling 8 cavities. Bake at 350℉ for 15–18 minutes or until lightly browned along the edges and no longer gooey or wet-looking on top. Watch carefully so they don’t burn and end up less flavorful and crumbly.
  • Let cool for 3–5 minutes in the muffin pan, then use the tines of a fork to gently coax the muffins out of the tin. Transfer to a wire cooling rack to allow the muffins to finish cooling.
Final step! Please let us know how it was by leaving a review.

Recipe Notes

Note 1: If you like your muffins sweeter, increase brown sugar by 1–2 tablespoons. Depending on your preference, start with 4 tablespoons and go up to 6.
Note 2: Make sure oats are certified gluten-free to have a gluten-free muffin.
Storage: Store leftover muffins in an airtight container at room temperature for up to 2 days, or refrigerate for up to a week. Freeze for longer storage.

    Hi Chelsea – this is the first time I’ve made the effort to leave a comment on a blog, because I’m so impressed! I’ve made these muffins a few times now (and your amazing lemon and chia seed muffins too) and can’t believe they’re butter, oil and flour free! I’ve tried a lot of gf and ‘healthy’ bakes out here in London and these are the best by far. I worked out the stats too and am so pleased!

    Thank you so much for your recipes 🙂 please keep up the great work!

      Awe this made my day! I’m so thrilled you’ve been enjoying the healthy muffin options on my site! I’m really happy about that 🙂 Thank you Kate!

  2. Michelle @ Modern Acupuncture says:

    Love that these are flourless and so healthy! My mom is trying to eat gluten free so with gluten free oats, this is perfect!

  3. Lynette neil says:

    I have made these muffins for the past 12months. It’s so reassuring to have a freshly made batch in the fridge.i eat these muffins every single day. Moist peanut butter banana choc chip ! What’s not to like !

    1. chelseamessyapron says:

      Oh this totally makes my day!! Such a great thing to hear!! Thanks for your comment Lynette 🙂

  4. Lainie says:

    I made a double batch to freeze and didn’t have enough peanut butter so I used some Reeses chocolate peanut butter spread instead and it turned out amazing!

    1. chelseamessyapron says:

      Ooo that sounds amazing!! So glad you enjoyed these; thanks for the comment 🙂

    I’ve made this recipe twice now… once with banana and once with apple sauce and crunchy peanut butter (accidentally bought crunchy instead of smooth); both turned out great! I’m not a baker by any means – most of my attempts are hit or miss at best – but this recipe is foolproof. Thank you so much for such a tasty, healthy and easy recipe! : )

    1. chelseamessyapron says:

      Oh this is SO great to hear!! So glad you’ve been able to switch it up and make some yummy muffins! Thanks for the comment 🙂

    Just made these and I’m in heaven. My boyfriend will no doubt probably eat all of them within two days (one day if I let him haha).
    I used crunchy peanut butter instead as well and it worked well, added a nice crunch to them! i didn’t have any chocolate chips but had a giant bar of dark chocolate so I chopped that into chunky pieces and they worked too. I totally forgot these are considered “skinny.” They taste so decadent!!!

    1. chelseamessyapron says:

      Haha so great to hear! I’m so glad you enjoyed these 🙂 And thanks for taking the time to leave a comment! I need to try these with crunchy peanut butter next time!

    I was looking for a peanut-choco recipe and I cane across this one! Boy, I am so glad i did, cause these muffins are soooo good! I didn’t have any honey or agave, so i put 1tb spoon of maple syrup (i had only that much:)) and I also put 1 teaspoon of cinnamon (i just can not live without it, what can i do?!:)). Oh, and the last thing: we europeans struggle a lot with american metric system, so maybe i didn’t use the exact amounts of oats and oat flour, but in the end it all turnerd out very well! So thank you for the recipe! I’m dure i’ll make these muffins often! Ciao from Italy!

    It look very attractive and appetizing. They would be perfect for the kids and me too! I’ll follow and try to do it at the weekend. Thanks for your guide

  9. Nadia says:

    These look yummy! I’m making them next week!
    Did you use unsweetened peanut butter? Could I use tahini instead?

    1. chelseamessyapron says:

      I just used regular peanut butter. I have never tried tahini in these so I can’t say if they would work or not but I do think the flavor would be off.
