Fluffy Spinach Muffins made right in the blender with old fashioned oats, ripe bananas, and fresh spinach. Naturally sweetened and ready in 30 minutes with bakery-worthy domed tops. Add chocolate chips if you fancy! 100% whole grain, gluten free, and nut free...perfect for school lunchboxes!

Who knew that whizzing spinach, oats, nanners, and a few other baking essentials could result in such a gorgeous green muff? It's a veggie party and you're all invited!
Have you gobbled up my healthy banana muffins, healthy chocolate banana muffins, or chickpea banana muffins yet? Gasp: no spinach banana muffin can be found in the muffin library! That all ends today.
I adore these because a) they're made in the blender, b) they have a fabulous lightness, c) they get my toddler to eat a vegetable, and d) they're way lower in sugar than most. Time to bake!

The main ingredients
- Old fashioned oats: Rolled oats are ideal here versus quick-cooking or steel cut.
- Spinach: Our supremely green leafy veg. Baby spinach or regular is great, just not frozen.
- Bananas: Brown and spotty ones like I use in all of my favorite banana recipes are the way to go! The more natural sweetness we have, the less added sugar needed. Boom!
- Eggs: Large eggs are key for structure and rise. I don't think egg substitutes will work well here. You could add a handful of spinach to any of my other egg-free muffins if you fancy!
- Oil: A quarter cup of oil (I like avocado oil because I'm too lazy to melt coconut oil) is perfect here. Any neutral oil works. You cold do olive oil if you don't mind fruity, floral notes.
- Milk: A splash of milk for much-needed moisture. Any milk you have on hand works.
- Coconut sugar: A more affordable, less refined sweetener that adds lovely caramel notes. Maple syrup, honey, or regular sugar all work! If you want to make spinach muffins for babies, simply omit the sugar.

Behind the scenes of recipe testing
I've made quite a few batches of these bad boys...some with almond and oat flour, some with more spinach, some with liquid sweetener, some with more fat.
On a mission to make a spinach muffin that stands above the rest, I perused existing recipes online (no one needs more of the same thing!) then gathered inspiration from all of my existing healthy muffin recipes.
I'm super pleased with the final result. Here's the why behind it all:
- Eggs are key for tall, fluffy blender muffins with that token rise. No eggs, no pretty domed tops!
- Ripe bananas not only offer sweetness, but extra flavor. My early attempts with less ripe yellow bananas came out with a more pronounced spinach taste.
- More spinach is not always merrier. I found that 2 cups of fresh spinach (remove any long stems) offered that lovely pop of green without leaving any spinach notes behind on the tongue, like 3-4 cups may.
- Ample fat prevents gumminess. When I tested these with only 2 tbsp oil, I didn't like the texture as much. With a quarter cup, they were perfectly moist with a nice delicate crumb. I find subbing applesauce leads to that off-putting, gummy texture.
- The sugar is adjustable. If you want sweeter, more "dessert-like" muffins, use ½ cup sugar. Honey or maple syrup worked well, too!
Let's make it (step-by-step!)

Place bananas, spinach, milk, oil, eggs and vanilla in blender.

Blend until smooth.

Add oats, coconut sugar, baking soda, baking powder, cinnamon, and salt. Blend until smooth.

Pour batter into muffin tin. Bake for 23 minutes.

Cool on a wire rack for 10 minutes and enjoy!
Storage
These beauties will keep in an air-tight container on the counter for up to 2 days. Refrigerate any leftovers after that. They freeze beautifully, too!
Let me know if you try this one! I love reading your feedback so much.

Marian Rankin says
This recipe arrived at the perfect time, with extra spinach to use up, wanting to find a new muffin recipe, and of course St Patrick's Day....
It is a 10 as far as taste, texture, height.... go. Just perfect!
I used a mix of choc. chips and raisins and doubled the amount. I always start with the oven at 450 for the first 5 minutes, then leave the muffins in but turn the oven down for the next 20-25 minutes. I use a thermometer and find the best temp is about 205 degrees,
I will definitely make this again.

Yayyy love those add-ins, thank you so much for sharing Marian!
Marian Rankin says
I missed a few points - after searching ways to get muffins to puff up:
After filling the muffin tins, I let the batter sit for up to an hour, to hydrate the flour, before baking. Then into the oven at 450 degrees.
I turn the oven down from 450 after 5 min, to 350 x approx. 20 min. I use a thermometer to check the internal temp. Should be approx. 205.
And... loving your website and using it daily. New ingredients (to me), healthy versions of favorites.... and all by an RDN, bonus!

I'm gonna start taking tips from you! Love it!! Please let me know what other recipes you try 🙂
Caroline says
My 3 year old wants this EVERY MORNING. I even used less than half of the sugar and no chocolate chips! And thanks Alexis for replying so quickly about the bananas (3 medium banana = 1-1.25 cups).
Alexis Joseph, MS, RD says
Awww this is the best, thank you Caroline! How adorable!
Caroline Lu says
I’m excited to try this especially for the oats and b/c it’s coming form you, an RDN! How much are 3 “medium” bananas like in cups, oz, mashed/sliced, etc.? Thank you!!
Alexis Joseph, MS, RD says
I'd say about 1 to 1 1/4 cups!
Tay says
Loved the recipe and the taste is amazing!
Followed your recipe to the T, came out really well. And, so healthy.
Alexis Joseph, MS, RD says
Yayyy so glad, thanks Tay!
Nicole Morell says
It worked! I don’t even have blender (just used my Ninja and worked in batches). I went light in the spinach (1 packed cup) because the green would have been a tough sell. Chocolate chips for insurance. Great texture, not too sweet. Success!
Alexis Joseph says
I'm impressed!! Thanks so much for the feedback, Nicole!
Kim says
I like the behind the scenes recipe testing and the "why" behind the recipe-so cool!
Alexis Joseph says
Yay! I thought it would help answer some reader questions I get often so I'm really glad you appreciated it, Kim!
Tay says
Amazing recipe! It is flourless too (not counting the oats), and I had to check the recipe twice to confirm! Came out really well! Thank you
Alexis Joseph, MS, RD says
So glad to hear it, thanks Tay!
Ashley says
I had some spinach I needed to use so I made these this AM. I thought I was preparing for the week but since I’ve already eaten 2 I’m not sure they’ll last long 😂. So delicious! Will definitely be making again!
Alexis Joseph says
Love this, thanks so much Ashley!!
Alexis Joseph says
So glad you liked them, Sarah!
