You may have heard these spinach muffins called "Hulk muffins," "Ninja Turtle muffins," "Green muffins," "Monster muffins". When you give it a fun title for the kids, they won't even realize healthy veggies are hidden inside! You might also call these "blender muffins" because the batter is quickly pureed in a blender.
We often buy fresh baby spinach from our local big club store because it's the same price there for a MUCH bigger package. But, this often means we have a bunch we need to use it up quickly before it goes bad. We also typically have ripe bananas we don't want to waste. These spinach muffins are perfect for that!

Top Tips and Tricks
Do not over mix. Once you add the dry ingredients to the blender, only pulse the mixture a few short times until it is JUST blended. I like to just pulse it 2 or 3 short times then gently fold the rest with my rubber spatula.
Do not over bake these muffins. If you bake them for the perfect amount of time, you'll keep a nice bright green color. Otherwise, the muffins reach a point in the oven where they start turning brown. So watch them carefully to achieve that perfect green!
Keep the spinach hidden, at first. The first time you make these, quickly whip them up before your kids can see the spinach. Then, after they try the muffins and declare they love them you can reveal the secret ingredient! The next time they can be involved and have fun helping you make them.
My kids love these muffins even though they know there is spinach in them. As you can see, my youngest couldn't even wait until I was done with our photo shoot to grab another one!
Serving Suggestions
Milk: I have tried making these muffins with oat milk, but they turned out way too dense
Oil: I've also tried melted coconut oil instead of the butter, which worked out just fine. Vegetable or canola oil is also a fine substitute for butter.
Mix-ins: You can try other variations such as stirring in a few nuts, chocolate chips, or even cinnamon chips!
Storage and Leftovers
Store: These muffins store well at room temperature in an airtight container. For best storage, line the bottom of container with a paper towel and another layer over top the muffins before placing the top on. This helps keep moisture away from the muffins.
Freeze: You can freeze spinach muffins in a freezer bag for up to 1 month. It may store longer, but my preference for best taste is 1 month.
