Key Ingredients

Healthy chocolate zucchini muffins.
  • Flour: You can use all-purpose flour, oat flour like I use in these Oat Flour Banana Muffins, whole grain flour, or a gluten-free flour blend. Using oat flour is my personal favourite for an extra boost of fibre!
  • Zucchini: use a box grater or the shredding attachment on a food processor to grate the zucchini.
  • Butter or oil: use melted butter, coconut oil, or any neutral tasting oil like avocado oil.

How To Store

Store the muffins in an airtight container at room temperature for up to 3 days or in the fridge for up to 5 days. For longer storage, freeze them for up to 2 months and thaw at room temperature before enjoying.

Jess’s Tips

  • Grate finely: Use the small side of a box grater so the zucchini blends seamlessly into the batter. You can use the larger size for a chunkier texture.
  • Use room temperature ingredients: Eggs and butter or oil at room temp will help create a light and fluffy muffin.
  • Adjust sweetness: Unlike these Almond Flour Banana Muffins that use mashed banana for sweetness, zucchini muffins are less sweet. This recipe uses 3/4 cup of maple syrup, but if you prefer your muffins less sweet, reduce to 1/2 cup.
  • Mix gently: Stir just until combined to avoid dense, tough muffins.
  • Add Mix-Ins: Chocolate chips are obviously great, but feel free to add some chopped walnuts like I add to these Healthy Banana Nut Muffins, pecans or dried fruit to these muffins.
  • Substitute zucchini: Swap the zucchini for mashed banana or pumpkin purée like I use in these Healthy Pumpkin Muffins for a seasonal variation.

Frequently Asked Questions

Can I make these muffins gluten‑free or dairy‑free?

Absolutely! Swap in gluten‑free flour or oat flour to make them gluten‑free. For dairy‑free, use a nondairy milk, coconut oil or avocado oil in place of butter and dairy‑free chocolate chips.

Why didn’t my muffins rise?

This can happen from over-mixing the batter, or using stale baking powder or baking soda. Mix just until combined and make sure your ingredients are fresh.

    So yummy! We keep making these muffins on repeat with the large zucchinis that grow in our backyard! 

    1. Jessica Hoffman says:

      So glad to hear you’re enjoying the recipe 🙂

  2. Kendra Stiwich says:

    I would really give this 4.5 stars. I find there is a bit too much baking soda taste, so I reduce to 3/4 tsp each. But other than that it is fabulous. Rick and chocolatey, moist, soft etc.

  3. Chef John says:

    I love muffins. Looks very tasty. Thanks for the recipe. I will definitely try.

    1. Jessica Hoffman says:

      Enjoy John!

  4. Alie says:

    These look deliciousI’d love to try making them but I was wondering if I can make them vegan by swapping the eggs with an alternative like ‘chia eggs’.  Do you think that would work?

    1. Jessica Hoffman says:

      Hi Alie, I haven’t personally tested out this recipe with a flax or chia egg so I can’t say 100% if it will work well, generally those swaps work pretty well to replace eggs in recipes.

      1. Alie says:

        Thanks Jessica! I tried making these with a chia egg and they turned out so good. Apart from the slight little crunch from the chia seeds (which I actually quite like) I doubt you’d know the difference.  I’ll definitely be making these again. Thanks for the lovely recipe. 

    2. Sarah L says:

      I subbed the eggs with apple sauce and it was delicious

        Happy you liked the recipe Sarah 🙂
