The Story: A Coffee Shop Smoothie Becomes a Muffin

These decadent (yet secretly healthy) mocha muffins are loaded with all the best flavors: banana, peanut butter, coffee, and chocolate. They also happen to be vegan, gluten-free, oil-free, refined sugar free, and high in protein. If you need any more incentive to make them, the batter comes together very quickly and right in the blender. It's muffin magic!

There's a fun story behind these vegan blender muffins too. One of our favorite coffee shops in the world, Java Kai on Kaua'i, has a "Wired Monkey" smoothie that's our absolute most favorite post-hike treat. It has coffee and bananas (hence the name) and we always ask them to add a big dollop of peanut butter too. We only get this smoothie after a seriously butt-busting hike, so it has become an incredibly special treat. Years ago I decided to borrow the name and work the flavors into a "wired monkey" muffin; I still make this recipe all the time because we love it so much.

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.

Although many blender muffin recipes call for eggs, this one is entirely plant-based. These vegan blender muffins get their moisture from banana and peanut butter. They get their loft from a combination of baking powder (which activates upon heating in the oven) and baking soda (which in this recipe reacts with a dash of apple cider vinegar to create air bubbles).

How to Make Vegan Blender Muffins

The secret to successful blender 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 chocolate chips) out of the batter when you blend it, then stir them in by hand at the end.

Coffee INSIDE a Muffin??

At the risk of stating the obvious, coffee and muffins are a natural pairing. But have you ever had coffee INSIDE your muffins? These mocha muffins get their nostalgic flavor from espresso powder and chocolate chips, so they taste just like a cozy mocha at your favorite cafe. Even though the muffins are dark in color, there's no chocolate in the batter itself; all that beautiful rich brown comes from espresso. I absolutely love using espresso powder in baking, but see the ingredient descriptions below if you'd rather substitute instant coffee, which is easier to find in stores.

Of course, you can also pair one of these wired monkey muffins with a cup of coffee. That combination makes for the most fabulous post-workout treat, especially because these muffins contain quite a bit of protein thanks to the peanut butter.

Ingredients and Substitutions

Here's what you'll need for this vegan blender 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.

  • Bananas. The riper the better! Make sure they're very soft, with ample brown spots, so that they provide as much sweet banana flavor as possible to these monkey muffins.
  • Plant milk. I like to bake with unsweetened soy milk because of its richness, but any plant milk will work.
  • Peanut butter. You can use a different nut butter (or even sunflower seed butter) if you have a peanut allergy, but good old PB really does yield the best flavor.
  • Maple syrup
  • Apple cider vinegar. I promise this isn't as weird as it sounds! The vinegar reacts with the baking soda to give these vegan blender muffins loft.
  • Vanilla
  • Old-fashioned rolled oats. Steel-cut or quick-cooking oats will not work.
  • Espresso powder. This is made by King Arthur Flour and can be found in well-stocked cooking stores or ordered online from their website. It's one of my favorite baking ingredients. If you can't find it, instant coffee will also work, although the flavor won't be as strong so you might want to double the amount.
  • Baking powder
  • Baking soda
  • Salt
  • Chocolate chips. Remember to choose dairy-free chocolate if needed. You can also use unsweetened chocolate chips if you're trying to avoid refined sugars entirely.

Closing Thoughts

How will you enjoy these cozy mocha muffins? Will you take them as a portable breakfast on a busy morning, snack on them after a workout, or even pack a couple for lunch? Thanks to the nourishing ingredients, they're super satisfying and can easily be all of those things. My biggest tip: they make for an excellent dessert as well, especially if you warm them up first. They're even better if you cut them in half and make a melty peanut butter wired monkey muffin sandwich (swoon!).

Seriously, how gorgeous and are these wired monkey muffins? I hope you'll make them again and again, just like we do. They're the best mixture of delicious, nutritious, and easy.

Vegan Mocha Banana ("Wired Monkey") Blender Muffins

These healthy mocha muffins have it all: sweet banana, energizing coffee, decadent chocolate, and luscious peanut butter. Can you believe they're vegan, gluten-free, and made in just minutes right in the blender?



  • 2 large, very ripe bananas
  • 0.5 c plant milk of choice
  • 6 tbsp peanut butter
  • 0.25 c maple syrup
  • 1 tbsp apple cider vinegar
  • 1 tsp vanilla
  • 2.25 c. old-fashioned rolled oats
  • 1 tbsp espresso powder
  • 2 tsp baking powder
  • 1 tsp baking soda
  • 0.25 tsp salt
  • Generous 0.5 c dark chocolate chips, plus more for sprinkling on top


  1. Preheat the oven to 350 and line a muffin tin with 12 liners.
  2. Measure the wet ingredients into a blender; putting the wet ingredients in first prevents the dry ingredients from clumping below the blades.
  3. Measure in the dry ingredients except for the chocolate chips.
  4. Blend everything until you have a smooth, thick batter.
  5. Add the chocolate chips to the batter and stir them in by hand.
  6. Pour the mixture evenly into the 12-muffin pan.
  7. Sprinkle each muffin top with a few additional chocolate chips.
  8. Bake 25-30 minutes until a cake tester just barely comes out clean. Let the muffins cool completely on a rack before removing them from the muffin tin.
  9. After cooling the muffins completely, store them in a tightly-sealed container in the fridge.

How much oat flour do I use I'm trying to learn to do things gluten free for my daughter and her family and I bought oat flour to use. Thanks

Tammi- Great question, thanks for asking! I love baking with oats (and oat flour) and I'm so excited you're experimenting with it. I usually just buy whole oats (they're less expensive) and then either make my own flour in a food processor or use the whole oats in a recipe like this that is made in a blender. But if you'd rather use oat flour in this one, I'd say about 1.75-2 cups. Whole oats are fluffier and take up more space, so in general you'll want to scale back a bit when you're adjusting from whole oats to oat flour. Even if you use oat flour, I think the blender approach to this batter will work fine. Hope that helps!

Meg- I don't suggest trying this recipe with almond flour. It just behaves so differently from oat flour. I worry your muffins would end up really crumbly and fragile. If you want an almond flour baked goodie though, check out my Nourishing Orange Macadamia Banana Bread!

Do you think these would work with almond flour instead?
