What You’ll Need

Here is what you’ll need to make these mini zucchini muffins:

Ingredients to make gluten free zucchini muffins.
  • Shredded Zucchini: Adds moisture and sneaks in a serving of veggies. Be sure to squeeze out any excess liquid after shredding.
  • Oat Flour: Keeps these muffins soft, hearty, and naturally wholesome.
  • Baking Powder & Baking Soda: Help the muffins rise and prevent them from becoming too dense.
  • Ground Cinnamon: Adds a warm hint of flavor.
  • Egg: Helps bind the batter together.
  • Greek Yogurt: Adds moisture, protein, and richness.
  • Oil: Keeps the muffins soft and tender. Use a mild-tasting oil like avocado oil.
  • Maple Syrup: Naturally sweetens the muffins.
  • Vanilla Extract: Adds warmth and enhances the overall flavor.

See the recipe card below for full information on ingredients and quantities.

Ingredient Substitutions & Additions

  • Greek Yogurt: Can be replaced with applesauce for a dairy-free option.
  • Egg: The egg may be replaced with a flax egg (Mix 1 tablespoon ground flaxseed with 3 tablespoons water and let sit for 5 minutes to thicken, then add in place of the egg).
  • Maple Syrup: Honey can be used in place of maple syrup (if serving these muffins to little ones over the age of 1).
  • Oil: The oil can be replaced with melted butter.

Step-by-Step Instructions

Steps to make gluten free zucchini muffins.

STEP 1: Preheat the oven to 350°F and prepare a 24-cup mini silicone (or metal) muffin pan.

STEP 2: Finely grate the zucchini using a box grater and use your hands or a clean kitchen towel to squeeze out the excess moisture (Image 1).

STEP 3: In a medium bowl, add the egg, Greek yogurt, oil, maple syrup, and vanilla extract. Whisk until smooth (Images 2 & 3).

STEP 4: Add the oat flour, baking powder, baking soda, and cinnamon and stir until just combined (Images 4 & 5).

STEP 5: Fold in the squeezed, grated zucchini and any add-ins (Images 6 & 7).

STEP 6: Spoon tablespoon-sized portions of batter evenly into the mini muffin pan (Image 8).

STEP 7: Bake the muffins for 15 minutes, or until the tops are set and a toothpick inserted comes out clean. Allow the muffins to cool fully before serving.

Storage Instructions

Once cooled, store the muffins in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. To freeze, place the muffins in a freezer-safe bag or container and freeze for up to 3 months. Reheat in the microwave for a few seconds or allow to thaw at room temperature.

Tips For Success

  • Make sure to squeeze excess moisture out of the zucchini so the muffins do not become gummy.
  • I love to use a silicone mini muffin pan for baking these mini muffins, as they pop out easily without sticking. If using a regular mini muffin pan, be sure to coat it with cooking spray beforehand. 
  • This recipe makes 24 mini zucchini muffins. You may make regular-sized oat bites by adding a few more minutes to the total bake time.

Frequently Asked Questions

Do I need to peel the zucchini?

No! The zucchini peel softens as the muffins bake and blends right in.

Why do I need to squeeze the zucchini?

Zucchini contains a lot of water, and removing excess moisture helps prevent soggy muffins.

      Hi Aparna! This recipe is for mini muffins which could pretty quickly, normal-sized muffins would need more time to cook, likely between 25 to 28 minutes. I hope they turned out!

    My littles INHALED these muffins!! I used blueberries instead of nuts so I could send them to school, and they are so tasty! With the blueberries, I think I can get away with cutting down the sweetener without getting busted 🙂

    1. Lily Payen says:

      I’m so happy to hear that your little one loved these! I love the idea of swapping the nuts with blueberries! Thank you for sharing your great feedback, Katie!😊
