These Healthy Zucchini Muffins have a perfectly fluffy texture and bake faster than a loaf of zucchini bread. You’ll get all the flavor you love in half the time!

Made with oat flour and grated zucchini, these tender muffins are a delicious way to use up any summer zucchini you have on hand. They are naturally sweetened with maple syrup and are easy to customize. 

Add in a few chocolate chips to make them taste like dessert, or fold in walnuts or pecans for extra crunch. 

Ingredients You’ll Need

Using oat flour keeps these muffins gluten-free, without using any complicated flour blends. Oat flour is made by simply grinding rolled oats in a blender, so this is something you can quickly make at home if you don’t have store-bought oat flour in your pantry.

Paired with maple syrup, cinnamon, and nutmeg, they have a classic flavor you’ll love.

Swap the maple syrup for 1/2 cup honey, if you prefer. (Honey has a stronger flavor when compared to maple syrup, so it’s important to use a little less when making swaps.)

If you prefer to use another flour and don’t need a gluten-free recipe, you can most likely swap this with white whole wheat flour or all-purpose flour. But, experiment at your own risk, as I haven’t tested these options on this recipe yet.

How to Make Healthy Zucchini Muffins

Preheat your oven to 350ºF and line a muffin tin with 12 parchment paper liners. (Greasing your muffin pan may be sufficient, but I like to use parchment muffin cups to guarantee they will be easy to remove later.)

In a large mixing bowl, combine the dry ingredients including the oat flour, baking powder, cinnamon, nutmeg, and salt. Whisk well to break up any clumps.

Next, add in the wet ingredients like the eggs, maple syrup, vanilla extract, and olive oil. If you prefer to use coconut oil or butter, just make sure the eggs are at room temperature, otherwise, it may clump up in your batter. (Another mild flavored vegetable oil will work, too.)

Stir until the batter looks relatively smooth, then fold in the shredded zucchini. Unlike other zucchini recipes, there’s no need to squeeze out extra moisture for this recipe. The oat flour will absorb it as it bakes! 

This also means you can use less oil, and don’t need to add extra moisture, like milk, mashed banana, or applesauce. 

Divide the batter evenly among the 12 prepared muffin cups. Sprinkle a few chopped walnuts or pecans on top for added texture, or add some chocolate chips for zucchini chocolate chip muffins that taste like dessert.

Bake for 25 to 30 minutes, until the top of the muffins are dry to the touch and spring back when you press on them. You can also insert a toothpick into the center of the muffin to make sure it doesn’t come out with any wet batter attached. 

Let the muffins cool for at least 15 minutes, then transfer them to a wire rack to finish cooling. Their texture will improve as they cool. Once they have cooled for at least 30 minutes, they are ready to enjoy! 

storage Tip

Muffins can be stored at room temperature for up to 24 hours, but since they are so moist, it’s best if you store them in an airtight container in the fridge for up to 5 days. Don’t be surprised if the tops of the muffins start to become sticky the next day. This is a natural consequence of using maple syrup as the sweetener (it often occurs in recipes that call for brown sugar, too).

  • 1 ½ cup oat flour (certified gluten-free, if needed)
  • 2 teaspoons baking powder
  • 2 teaspoons ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ¾ teaspoon fine sea salt (I use Real Salt brand)
  • 3 large eggs
  • â…” cup maple syrup
  • ¼ cup olive oil (or other vegetable oil)
  • 2 teaspoons vanilla extract
  • 1 ½ cups shredded zucchini (no need to squeeze)
  • â…“ cup chopped walnuts or pecans (optional)
  • Preheat the oven to 350ºF and line a muffin tin with 12 parchment paper liners. In a large bowl, combine the oat flour, baking powder, cinnamon, nutmeg, and salt. Whisk well to break up any lumps.

  • Next, add in the eggs, maple syrup, olive oil, and vanilla extract. Stir until the batter looks relatively smooth. Then stir in the shredded zucchini. (No need to squeeze out the extra moisture from the zucchini; the oat flour will absorb it as it bakes.)

  • Divide the batter evenly among the 12 muffin cups. Top each muffin with chopped nuts, if desired. (They add a nice crunch! But chocolate chips are an option, too.) Bake at 350ºF for 25 to 30 minutes, or until the tops of the muffins feel dry and spring back when you lightly press on them.

  • Let the muffins cool in the pan for 15 minutes, then transfer to a wire rack to finish cooling. The texture will improve as they cool; oat flour can have a gummy texture when warm. Once they have cooled for at least 30 minutes, then are ready to serve. Cooled muffins can be stored in an airtight container in the fridge for up to 5 days.

Nutrition information is for 1 of 12 muffins without the optional nuts on top. This information is automatically calculated and is just an estimate, not a guarantee.
Need to use another sweetener? Honey should also work, but I would use less, starting with just a 1/2 cup.
Need an egg-free recipe? I don’t think 3 flax eggs would work well here but check out my vegan pumpkin muffins as a starting point. I think swapping the pumpkin for zucchini should work similarly.
