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.
How To Make Peanut Butter Banana Muffins
- Preheat oven and grease muffin tin.
- Mash banana and mix with peanut butter, honey, vanilla, brown sugar, and egg.
- Blend oats to make oat flour.
- Add salt, baking soda, baking powder, oat flour, oats, and chocolate chips to the mixture.
- Scoop into muffin tin and bake until set.
- 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
- 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 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.

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! 🙂
You make the most gorgeous skinny muffins! I would love that undercooked center 🙂 And mainly because there is so much PB involved!
I can never get enough skinny recipes. I love this skinny version and would love to have it everyday for breakfast. YUM! 🙂
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
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.
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!
I was JUST searching for a peanut butter and chocolate muffin recipe last night! What perfect timing 🙂 These look so good!
Banana and peanut butter? Always a winning combination!
All the best things! These muffins are perfect for tea time!
I love underbaked muffins! These sound delicious and I can’t wait to give them a try!
