Meet the newest member of my green monster family – green monster muffins! Actually, they’re not new in any sense, since I’ve been making them since Oscar started eating solid food, BUT they are new to LIMO. I got the original recipe from a friend a few years back, courtesy of a blog called the Green Forks; it looks like the site is no longer up and running, but luckily I’ve made and tweaked the recipe enough over the years that I don’t actually need the site anymore!

These muffins were actually the inspiration behind my green monster baked donuts too! It’s an easy, fun way to get a TON of spinach into kids, without them even knowing it. Muwahah!

If you’ve been following along for a while, you’ll know that I love to bake without refined sugars (as much as possible), and bananas are one of my favourite ways to pack a ton of natural sweetness into something; these banana muffins are only sweetened with banana!

Are green monster muffins sugar free?

Since we’re packing a whopping 6 ounces of spinach into these bad boys, you will definitely want to add some additional sweetener along with the bananas; my preference is honey, but if your babe is under 1 or you’d prefer a different sweetener, you can swap the honey for agave or maple syrup.

How do you make green monster muffins?

The muffins are super easy to make! The spinach and bananas are combined in a blender or food processor, along with the other wet ingredients, and then mixed into the dry. I use a combo of whole wheat flour and white flour to ensure the muffins aren’t too dense and heavy; I’ve never been able to get my hands on white whole wheat flour, but if you have some I think you could use it, instead of the mix.

Isn’t this green colour just brilliant!? I love it! The kids don’t mind it either – they’re still too young to be scared of anything green. I am being 100% honest when I say the first day I made these, Wally would not stop asking for them. I think it’s pretty much all he ate that day, and I was ok with it (yay spinach)! It certainly made for an interesting diaper the following day….sorry…

Since it’s March 2nd, I figure it’s perfect timing to start rolling out all of the green recipes in my arsenal – I’ve got a few more up my sleeve! If you need a healthy St. Patrick’s Day inspired treat for your kids, or for yourself, you’ve gotta try these monster muffins!

Green Monster Muffins

  • Author: Katherine
  • Total Time: 33 minutes
  • Yield: 15 muffins 1x


Sneak some spinach into your family’s diet in the form of a vibrantly green, fluffy muffin sweetened with natural sugars and full of healthy ingredients. 


  • 3/4 cup all-purpose flour
  • 1 1/4 cup whole wheat flour
  • 2 tsp baking powder
  • 1/2 tsp baking soda
  • 1 tsp cinnamon
  • 1/2 tsp salt
  • 3/4 cup almond milk*
  • 5 oz fresh spinach
  • 1/4 cup avocado oil*
  • 2 ripe bananas
  • 3/4 cup honey
  • 1 tsp pure vanilla extract


  1. Line two 12-cup muffin tins with liners (you’ll make about 15) and preheat the oven to 350 F. 
  2. In a large mixing bowl, combine together the flours, baking powder, baking soda, cinnamon and salt together. 
  3. To a blender or food processor, add the almond milk, spinach (pack it down to fit), oil, bananas and honey and mix on high until the spinach is completely pureed. Add the vanilla extract and mix for a few more seconds. 
  4. Pour the blender contents into the dry ingredients, and stir together just until combined. Fill the muffin tins about 2/3 – 3/4 full and bake for 16-18 minutes*, or until a toothpick comes out clean. Allow the muffins to cool in the pan for about 5 minutes before removing to a wire rack to cool completely. 

Muffins stay fresh at room temperature in an airtight container for 3-4 days; they will last longer in the fridge and can be frozen for up to 2 months. 


  1. Use any type of milk in place of almond milk (dairy, coconut, etc)
  2. Melted coconut oil, grapeseed oil, or vegetable oil also work
  3. For mini muffins, bake for 10-11 minutes.

  12. dang, the amount of spinach in here is impressive (; definitely thought these were matcha at first, but i think that just means i’ve been consuming too much tea lol.

  32. Amazing, so good. My toddlers gobble them right up. We only used 1/3-1/2 cup of honey and it was still sweet enough!

  33. I love these fun green monster muffins!!! The best way to sneak in some greens!

  34. This is the fourth time I’ve made these. It’s such a quick and easy recipe and my toddler is in love with them! I put the whole batch in the freezer after I make them and heat one up for a few seconds in the microwave when I need a quick morning snack for her. I also appreciate that the recipe helps prevent food waste too because I wait to make them until we have spinach and bananas that are a little older and need to be used.

  35. How many cups of packed spinach is in 6 ounces? Thank you!

  36. Oh MY, it looks great! Can’t wait to cook em this Sunday!
