Warm peanut butter banana muffins topped with chocolate chips, freshly baked and ready to enjoy.

Peanut Butter Banana Muffins

After receiving such a positive reception for my Chocolate Peanut Butter Muffins, I wanted to share a non-chocolate version featuring bananas. While there are numerous banana treats on this site, both healthy and indulgent, these muffins are the first to irresistibly combine bananas and peanut butter.

If you’re a fan of bananas, peanut butter, oats, and dark chocolate, you’ll love these muffins!

Making oat flour by placing oats in the blender and processing them until they are pulverized into flour.

Ingredients In Peanut Butter Banana Muffins

  • Overripe Banana: Contributes natural sweetness and moisture, resulting in soft textured muffins.
  • Creamy Peanut Butter: Adds richness and flavor, and helps in binding the ingredients.
  • Honey & Light Brown Sugar: These sweeteners improve the flavor and contribute to a moist texture.
  • Vanilla Extract: Provides a subtle fragrance and enhances the overall flavor.
  • Egg: Acts as a binder, giving structure and stability to the muffins.
  • Salt: Balances the sweetness and enhances the overall flavor.
  • Baking Soda & Baking Powder: Serve as leavening agents, helping the muffins rise and become fluffy.
  • Oat Flour: Made from blended oats, it gives the muffins a hearty texture and serves as a gluten-free flour alternative.
  • Old-Fashioned Oats: Adds texture and a chewy bite.
  • Dark Chocolate Chips: Provide sweet, chocolatey bursts in each muffin.

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.

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.

Tips For Success

  • Use very ripe bananas for sweeter muffins.
  • 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 flavor.
  • Tip for Storage: Store muffins in an airtight container to keep them fresh.
  • Freezer Tip: Freeze muffins in a sealed container or bag. Thaw at room temperature or microwave briefly for a quick treat.

Peanut Butter-Banana Muffins

These Peanut Butter-Banana Muffins are gluten-free, nutritious, and packed with flavorโ€”all without oil, butter, or refined white flour!
Prep Time: 20 minutes
Cook Time: 18 minutes
Total Time: 38 minutes
Servings: 8 muffins

Equipment

  • Muffin pan with 8 cavities
  • Blender or food processor

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 350ยฐF. 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 350โ„‰ for 15โ€“18 minutes or until lightly browned along the edges and no longer gooey or wet-looking on top. Watch carefully so they donโ€™t burn and end up less flavorful and crumbly.
  • Let cool for 3โ€“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.

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 ๐Ÿ™‚ please keep up the great work!

  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 ๐Ÿ™‚

  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 ๐Ÿ™‚

    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 ๐Ÿ™‚

    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 ๐Ÿ™‚ 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! Iโ€™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.
