These Chocolate Peanut Butter Swirl Muffins are a no-fuss, easy and delicious way to get a chocolate fix in the mornings! Not too sweet, perfectly moist and mouthwatering! 

This recipe was originally published in May 2019 – I’ve since updated the photos and added additional blog content. Enjoy! 

I remember when I was younger and my mom would drive me to school. We were usually running late (not much has changed in that sense ha!) so we would often stop at the grocery store to pick up breakfast. 

Instead of getting my usual Lil Debbie Cake – I’m looking at you, honey bun! My brother, mom and I began to get super fancy and pick up muffins from the bakery. You could buy them in a box of 4.

You could mix and match so my brother would get chocolate chip, mom would get blueberry and I would often get pistachio because they looked SUPER cool due to the fact that they were green. 

That point of that insanely long story is: I have always loved muffins. Any kind, anytime, anywhere. But lately, I am pretty partial to these Chocolate Peanut Butter Swirl Muffins. Why, you ask? Well…

Why You’ll Love These Muffins:

  1. They’re not loaded with sugar 
  2. They’re incredibly moist 
  3. It literally feels like you’re having cake for breakfast 
  4. The combination of chocolate and peanut butter is always and forever unbeatable 
  5. They’re insanely easy to make (aka one bowl goodness!) 

But really, y’all. These muffins have a deep cocoa flavor and they are studded with chocolate chips throughout but they never reach that “overly sweet” level that some muffins have.

They are super moist, melt in your mouth goodness. The peanut butter swirl on top gives them a nuttiness that’s the perfect balance to the dark chocolate flavor. 

When you slather extra butter or nut butter on top, they are just mind blowingly good. Let’s get into how to make them! 

Ingredients you Need:

  • Your favorite smooth peanut butter (the more natural oily kind works best) 
  • Ripe bananas 
  • Maple syrup 
  • Egg
  • Vegetable oil (or any neutral oil should work) 
  • All purpose flour 
  • Chocolate chips 
  • Cocoa powder 
  • Butter or cooking spray (for greasing the muffin tins) 

Best Muffin Baking Tips: 

It’s always best to make sure that your oven is adequately heated when you’re about to bake! So be sure to preheat the oven to 375 and give it enough time to fully warm up. 

Next, feel free to use butter or cooking spray to grease your muffin tin (or use muffin liners) and set aside. You can use either a 12 count muffin tin or 6 count jumbo muffin tin for this recipe. 

In a large bowl, mash your very ripe bananas until all the lumps are gone. 

To this, add maple syrup, vegetable oil, 1 egg and mix until fully combined with a whisk. To this bowl, sift in flour, baking soda, baking powder and salt. Mix gently to combine. Lastly, if desired, gently fold in those chocolate chips! Raise your hand if you love baking in one bowl!! *raises both hands*

Next, grab that muffin pan and fill each liner with the prepared batter until about halfway full. 

To this, add about 1 tbsp of peanut butter and using a butter knife, swirl it in the batter. I found that using the more natural “oily” peanut butter (or nut butter) works best for this recipe. 

Bake for 20-22 minutes or until a toothpick comes out fully clean. Let them cool in the muffin pan for a few minutes – or as long as you physically can, ha!

Then gently move them to a cooling rack. Enjoy warm with a schmear of salted butter or more peanut butter!

These would be perfect for meal prep, breakfast on the go, a fun brunch option or just for a snack in the middle of the day! Enjoy! 

Storing Leftovers: 

Store these in a tightly sealed tupperware container for 2-3 days at room temperature. Of course, they are best eaten the day of 😉

Recipe Notes

I have used both a jumbo 6 muffin tin pan and a 12 count muffin tin for this recipe and they both work!

For peanut butter, it's best to use a natural more "oily" peanut butter for this recipe 🙂

    I just made these today and they are perfect! I didn’t alter anything and the texture is amazing and the gooey peanut butter center was delicious. Can’t recommend these enough. Thank you! And yes, pb and chocolate cannot be beat!!

    1. Hi Elana! I’m not sure…I haven’t ever tested it myself. However, I did a quick search for you and found a lady who has done it before in other muffin recipes. She said: “If you’re just trying to make your muffins more hearty, substituting oat flour in a smaller quantity should also work. I have a general rule to keep it to about 1/2 cup substituted flour for a 12-muffin recipe.” Let me know if it works out! 🙂

    These look delicious, but I tried them and unfortunately they were not tasty. Also the peanut butter stayed in one glob on top and was very firm

    1. Hey Jazz – I’m so sorry this recipe didn’t work out for you 🙁 Did you use a more natural “oily” peanut butter? Usually that type works best for this recipe. I’ve since updated the recipe card to add that detail. Sincerest apologies for not having it there before. Thank you for your feedback! Hope you’re staying safe and well during this time! Best – Haylie

  6. So, I made these for the first time today and they were very easy to make and the house smelled amazing! The one thing I found odd was the peanut butter at the top. I used Crazy Richards creamy peanut butter and at about 18 minutes the peanut butter at the top looked kind of dry. I might not have put enough peanut butter and filled the cups too high because they did rise a lot and the peanut butter topping spread out and dried out a little. But overall they looked pretty good and smelled even better! AS for the taste, they are amazing! Not too sweet but not bland. Is definitely a treat I feel good about 🙂 Thanks for the recipe, will be saving it for later . Oh yeah and at 23 minutes the bottoms of mine started to burn a little but our oven runs a little hotter.

    1. Hi Yesenia! Thank you so much for making this recipe and for your feedback! So glad to hear that you enjoyed them! I agree – I love that they’re not overly sweet but also not bland. So good! 🙂 Hope you’re well! Best – Haylie

    Made these for the family and they were a huge hit! Super soft, moist, perfect amount of banana taste, and perfect level of sweetness (perfect!!!). Will definitely be making again.
