Can you think of a better way to eat vegetables than when they’re baked into a chocolate dessert? I can’t!

My Chocolate Zucchini Muffins are incredibly fudgy and moist, just like your favorite vegan chocolate cake or double chocolate cookies. The only difference? These muffins are chock-full of grated zucchini to give them a boost of nutrients and moisture.

You’re going to love that these vegan muffins made with zucchini and chocolate chips don’t taste like vegetables. The subtle flavor of the grated zucchini blends right into the chocolatey batter and makes the muffins extra moist. It’s a great alternative when you don’t want to add more oil or vegan butter into the batter. 

If your garden is overflowing with more zucchini than you know what to do with, make a double batch of these vegan zucchini muffins and my 1-bowl Zucchini Bread as well. Both are freezer-friendly so you can enjoy rich and soft desserts all summer long!

How to make chocolate zucchini muffins

Your muffin tin is lined, the oven is preheating, and the zucchini is grated and drained. It’s time to get these muffins going!

  1. Whisk all of the dry ingredients in a large bowl and the wet ingredients in a separate medium bowl. Fold the grated zucchini into the wet ingredients.
  2. Pour the wet mixture over the dry and stir until just combined. Fold in the chocolate chips.
  3. Divide the muffin batter into the lined muffin cups, sprinkle the tops with extra chocolate chips, and bake. 
  4. The muffins are done when a toothpick inserted in the middle comes out clean. Leave them to cool completely, then enjoy!

Baking with zucchini

There are a few tips you need to know if you’re baking with zucchini for the first time. To begin, grate the zucchini finely either using a box grater or food processor. Small pieces of zucchini baked into the muffins will help each one bake evenly and result in a much softer and enjoyable texture.

You’ll need to strain the grated zucchini of as much moisture as possible to ensure your muffins turn out decadent and rich. After grating, place the zucchini in a fine mesh strainer and gently press it down to drain the excess water. If you don’t have a strainer, wrap the zucchini tightly in a clean kitchen towel and squeeze out as much water as you can over the sink.

Tips and substitutions

  • Sweetness – If you’d like the muffins to taste less sweet, use slightly less sugar in the recipe. If you’d rather they taste more sweet, add more sugar!
  • Gluten free – Swap the all purpose or whole wheat flour for a gluten free 1:1 flour blend instead.
  • Walnuts – For an added crunch, add in ½ cup of chopped walnuts into the batter.
  • Oil free – Replace the oil in the recipe with ¼ cup of applesauce instead.

Can you freeze zucchini muffins?

Yes! Vegan zucchini chocolate chip muffins freeze so well and make for a quick and delicious snack. Just freeze the baked and cooled muffins in a freezer-safe bag or airtight container and let them thaw first or pop them in the microwave for a few seconds before snacking.

5 stars (8 ratings)


  • 1 1/2 cups all purpose flour*
  • 1/2 cup dutch-processed cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup unsweetened soy milk, or almond/coconut/oat
  • 1/4 cup neutral flavored oil, such as canola, grapeseed, melted coconut
  • 2 tablespoons ground flaxseeds
  • 3/4 cup granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 cup lightly packed grated zucchini, drained of excess water, about 1 medium zucchini
  • 3/4 cup vegan chocolate chips


  • Preheat the oven to 350 degrees F. Line a standard muffin pan with liners and spray them lightly with oil so the muffins don't stick to the liners.
  • In a large bowl, add the flour, cocoa, baking powder and salt. Whisk well to combine.
  • In another medium sized bowl, whisk together the soy milk, oil, ground flaxseeds, sugar and vanilla until smooth. Lightly squeeze excess water out of the grated zucchini, then stir it into the wet ingredients.
  • Add the wet mixture to the bowl with the dry ingredients and stir until just combined, being careful not to over mix.  Fold in the chocolate chips, saving some for the tops.
  • Divide the batter among the muffin cups, filling about 3/4 of the way full. Sprinkle with extra chocolate chips, if desired. Bake for 20-23 minutes, or until a toothpick inserted in the middle comes out clean.
  • Cool in the pan for about 5 minutes, then carefully transfer to a cooling rack. Enjoy!
  • Muffins will keep for up to 3 days in an airtight container at room temperature, or up to 5 days in the refrigerator. They also freeze well.


  1. May substitute a gluten free flour mix (I like King Arthur Cup for Cup) or whole wheat pastry flour. 
  2. You may use natural cocoa powder, but the muffins won’t be as dark. 
  3. For oil free, substitute the oil with applesauce.
  4. Consider adding 1/2 cup chopped walnuts for extra crunch.
