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!

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.

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.

    I have always wanted to make big puffy bakery-style muffins, but could never get them to look like that. So I never really make muffins. I could probably do these, though! Love how healthy they are too! I can’t believe there isn’t any butter or oil. So impressive! ๐Ÿ™‚

  2. Mary Frances says:

    You make the most gorgeous skinny muffins! I would love that undercooked center ๐Ÿ™‚ And mainly because there is so much PB involved!

  3. Layla @ Brunch Time Baker says:

    Underbaking muffins is the best – even if they don’t look perfect, the texture is PERFECT!! These look so delicious – and I’m obviously a sucker for chocolate peanut butter, mmmm

  5. Rebecca @ Dorm Room Baker says:

    I’ve always been a big proponent of underbaking brownies and some cookies, but never thought to do it with muffins. I adore how healthy these are since I know I’m going to end up eating maybe 10 of them I don’t have to feel quite as guilty haha.

  6. Gayle @ Pumpkin 'N Spice says:
