Cozy and Healthy Peanut Butter Muffins

Are you a peanut butter lover? If so, these decadent seeming (yet actually healthy) peanut butter banana muffins are for you. They're bursting with indulgent peanut butter flavor, yet are made with nourishing ingredients like banana and whole oats. These beauties are gluten-free, oil-free, and refined sugar-free, so they're a treat you can feel good about enjoying. Best of all, the batter is made in just a couple minutes right in the blender.

These aren't ordinary blender muffins though; they have a special treat hiding inside. Each muffin has a creamy, flavorful dollop of peanut butter tucked away in its center. Dreamy, right? I can't wait for you to try them!

What Are Blender Muffins?

Like the name implies, blender muffins are made right in the blender. They're convenient, fast, and minimize dirty dishes. Additionally, because you're enlisting the help of the blender, you can use whole oats as the flour element. No need to buy pricey oat flour or dirty a separate kitchen gadget to grind your own oat flour.

Intrigued? I think you'll also love these Vegan Morning Glory Blender Muffins and these Vegan Mocha Banana Blender Muffins.

How to Make Blender Muffins

The secret to these healthy peanut butter muffins is to add the wet ingredients before the dry; using this sequence helps to prevent the dry ingredients from clumping below the blades. Other than that, this is basically just a dump-and-blend recipe; there's no separate bowls for wet/dry, no fussy sifting, and no melting of butter. Just remember to keep your mix-ins (in this case the chocolate chips) out of the batter when you blend it, then stir them in by hand at the end.

The only part of this recipe that requires more than a few minutes is adding the gooey peanut butter filling. You'll put about half the batter into the muffin cups to start, then add a dollop of PB right into the center of each, then put the rest of the batter on top. The key is to use a non-drippy peanut butter so that it will hold its shape without leaking into the surrounding batter.

Ingredients and Substitutions

Here's what you'll need for this healthy peanut butter muffin recipe, as well as some thoughts, tips, and possible substitutions. If you make any substitutions, I'd love to hear about it in the comments section below.

• Ripe banana
• Eggs. This is an old recipe and I haven't (yet!) tried a vegan version. I expect it will work fine with flax or chia eggs, or even just a few extra spoonfuls of peanut butter, although the muffins will have less loft. Please let me know in the comments if you try it.
• Milk. I usually make these muffins with unsweetened soy milk because of its richness, although I've also made them with chickpea milk and almond milk. I have not tested them with dairy milk.
• Non-drippy peanut butter. You'll use PB both to provide fat (and flavor!) to the batter and to stuff the muffins. For stuffing, make sure to use a non-drippy peanut butter so that it holds its shape in the muffin centers without leaking into the surrounding batter.
• Maple syrup. Or feel free to use honey for a different flavor profile.
• ‍Whole rolled oats
• Baking powder
• Baking soda
• Salt
• Chocolate chips. I prefer dark chocolate to offset the delicate sweetness of these peanut butter banana muffins, but you can use what you prefer (choose dairy-free if needed).
• Flaky sea salt. For garnishing the tops of the muffins and creating a sweet/salty balance.

Closing Thoughts

I think blender muffins are such great proof that baked goods can still nourish the body. These easy peanut butter banana muffins are made from whole food ingredients, with no oils and no refined sugar. They have good fiber thanks to the oats and healthy fats thanks to the peanut butter. They're satisfying without feeling heavy, with no sugar crash after (unlike bakery muffins, which are essentially just cake in disguise).

Aren't these healthy peanut butter muffins fun? The combination of the fluffy, hearty muffin with the gooey peanut butter center is absolutely divine. Whether you enjoy them as an easy breakfast, a portable snack, a post-workout treat, or even dessert, I hope you love them as much as we do.
