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.

    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! 🙂

  2. Mary Frances says:

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

  3. Layla @ Brunch Time Baker says:

    5 stars
    I can never get enough skinny recipes. I love this skinny version and would love to have it everyday for breakfast. YUM! 🙂

  4. Cate @ Chez CateyLou 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:

    As soon as I saw peanut butter and banana muffins, I just had to pin this right away. These sound so delicious, and I absolutely LOVE that they’re gluten-free! Beautiful pictures, too!
