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!

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 (looking at you, honey bun!), my brother, mom and myself began to get super fancy and get 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…

  • they’re not loaded with sugar
  • they’re incredibly moist
  • feels like you’re having cake for breakfast
  • the combination of chocolate and peanut butter is always and forever unbeatable
  • 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, and they literally melt in your mouth.

The peanut butter swirl on top gives them a nuttiness that’s the perfect balance to the dark chocolate flavor. I definitely recommend the Nuttzo brand – it’s SO smooth and you don’t have to stir the oil in like with normal “natural” peanut butters. It’s already super smooth and ready to eat! And pro-tip, y’all: when you slather extra butter or extra Nuttzo peanut butter on top of these muffins, they are just mind blowingly good.

Let’s get into how to make them!

Ingredients you need for Chocolate Peanut Butter Swirl Muffins:

  • Nuttzo peanut butter (I used the Peanut Pro Smooth flavor for this!)
  • ripe bananas
  • maple syrup
  • egg
  • vegetable oil (or any neutral oil should work)
  • all purpose flour
  • chocolate chips
  • cocoa powder
  • baking powder + baking soda
  • butter (for greasing the muffin tins)

How to Make Chocolate Peanut Butter Swirl Muffins:

Preheat the oven to 375. Using butter, grease your muffin tin (or use muffin liners) and set aside. In a large bowl, mash 3 medium 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, cocoa powder, baking soda, baking powder and salt. Mix gently to combine. Add in your chocolate chips after it’s mixed and fold them in gently. Raise your hands if you love baking in one bowl!!

I used a jumbo 6 muffin tin for this recipe. Feel free to use the 12 muffin tin pan. Fill with batter until about halfway full. To this, add about 1 tbsp of the Nuttzo peanut butter and using a butter knife, swirl it in the batter.

Bake for 20-22 minutes or until a toothpick comes out fully clean. Let them cool for 2-3 minutes in the muffin pan and then gently move them to a cooling rack. Enjoy warm with a schmear of salted butter or more  peanut butter!

    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! 🙂
