The BEST Chocolate Zucchini Muffins

These chocolate zucchini muffins are wonderfully chocolaty, and anytime I can eat chocolate for breakfast, I’m happy. And when a recipe is on the healthier side, even better. There’s no dairy, no butter, and only 1/4 cup oil in the entire batch!

These zucchini bread muffins are easy to make and you don’t need a mixer. They’re extremely soft, tender, and moist all thanks to zucchini. If you’ve never baked with zucchini before, this is the recipe to start with.

If you’re not a zucchini fan, I promise you can’t taste it. I think it’s fairly neutral-tasting and takes on the flavor of the ingredients it’s prepared with, but my family has keen tastebuds for zucchini and they couldn’t detect it. I recommend finely grating the zucchini with a box grater. It incorporates better both in terms of texture and undetectable flavor when it’s finely grated.

What’s in Chocolate Zucchini Muffins? 

For this easy zucchini muffin recipe, you’ll need:

  • Grated zucchini
  • All-purpose flour
  • Granulated sugar
  • Unsweetened cocoa powder
  • Baking soda 
  • Salt
  • Egg
  • Silk Dark Chocolate + Walnut Nutchello
  • White vinegar
  • Vegetable oil
  • Vanilla extract
  • Boiling water
  • Mini chocolate chips

This is the perfect recipe to have on hand during the warmer months when zucchini is in season! Make a big batch and share some with your neighbors — they’ll love you for it!

Is There a Nutchello Substitute I Can Use? 

To intensify the chocolate flavor, I used Silk Dark Chocolate + Walnut Nutchello. However, this product is no longer available. Instead, feel free to use another of Silk’s non-dairy milks in this. Their regular soy, almond, or coconut milk would work well in these chocolate zucchini muffins, as would regular chocolate milk. Use whatever you can find!

How to Make Chocolate Zucchini Muffins

To make these chocolate zucchini muffins, you’ll first need to grate the zucchini. Then, add the wet ingredients to one bowl and the dry to another. Combine the wet and dry ingredients, then stir in the zucchini and boiling water. Note that the batter will be very thin! 

Stir in the mini chocolate chips, then divide the batter among the prepared muffin tins and bake the zucchini muffins until a toothpick in the middle comes out clean. Let the muffins cool for a few minute in the tins before removing them (otherwise you might break them).

How to Freeze Muffins

If you have a lot of zucchini to use up, make a few batches of chocolate zucchini muffins and freeze them for later! To do so, let the muffins first come to room temperature, then pop them into a zip-top bag and freeze.

When you’re ready to eat the frozen muffins, either nuke them in the microwave for 30 seconds or let them come to room temperature on your countertop.

I like having frozen muffins on hand for quick afternoon snacks or grab-and-go breakfasts. These muffins are so flavorful on their own that you don’t need to worry about adding toppings to them (although these taste amazing with a little peanut butter on them!).

Tips for Making Chocolate Zucchini Muffins

First and foremost, the water MUST be boiling when you add it to the batter. Hot tap water won’t cut it here — you actually need to boil the water in a kettle. It makes a big difference, trust me! 

Also, if you don’t have white vinegar on hand, another neutral vinegar (like apple cider vinegar) will work. Just don’t use a really flavorful vinegar like balsamic in this recipe, since that would alter the flavor of the muffins. 

To make these chocolate zucchini muffins prettier, I like to sprinkle a few more mini chocolate chips on top before baking them. It just adds a little something, and makes these zucchini bread muffins seem even more decadent.

Ingredients  

  • 1 cup finely grated zucchini, measured loosely laid and not packed in the cup (from about 1 medium zucchini)
  • 1 cup all-purpose flour
  • ¾ cup granulated sugar
  • cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ¼ teaspoon salt, or to taste
  • 1 large egg
  • ½ cup Silk Dark Chocolate + Walnut Nutchello, Silk Soy, Almond, or Coconutmilk, or chocolate milk, may be substituted
  • 2 teaspoons white vinegar
  • ¼ cup canola or vegetable oil
  • 1 teaspoon vanilla extract
  • ½ cup boiling water
  • ½ cup semi-sweet mini chocolate chips
  • about 12 teaspoons semi-sweet mini chocolate chips, divided

Instructions 

  • Preheat oven to 350F. Line a 12-Cup Regular Muffin Pan with liners; set aside.*
  • Grate the zucchini on the fine blade of a box grater; set aside.
  • To a large bowl, add the flour, sugar, cocoa powder, baking soda, salt, and whisk to combine; set aside.
  • To a medium bowl, add the egg, Nutchello, vinegar, oil, vanilla, and whisk to combine.
  • Pour the wet ingredients over the dry and stir to combine; don’t overmix but take care to make sure all dry bits are incorporated at the bottom of the bowl.
  • Add the zucchini and stir to combine.
  • Add the boiling water and stir to combine. Batter will be thin.
  • Add 1/2 cup mini chocolate chips and stir to combine.
  • Fill each muffin liner 3/4 full. Some of mine were a bit fuller than 3/4 because the batter is thin and was ‘pouring fast’ but it’s okay because the muffins don’t rise a ridiculous amount.
  • Evenly top each muffin with a generous pinch of mini chocolate chips, about 1 teaspoon per muffin.
  • Bake for about 20 minutes or until tops are domed, set, and a toothpick inserted in the center comes out clean or with a few moist crumbs. Cool muffins in pan on a wire rack for about 10 to 15 minutes or until you can remove them. Muffins will keep airtight at room temp for 5 days or in the freezer for up to 4 months.

Notes

*Note: I had enough batter for about 13 to 14 muffins, but opted to make a mini loaf that I baked alongside the 12-count muffin pan because my oven is too small for two large pans at once. Do what’s most convenient or discard excess batter.

    This is my go-to recipe during zucchini season when I have a zucchini that gets forgotten in my fridge for a few days. :) So chocolate-y and delicious! I substitute chocolate milk for the Nutchello, since I don’t have that on hand, and it tastes just great! (Though maybe it would taste even better with that…Hmmm…) Thanks for a great recipe!!

  2. 2 stars
    I was really looking forward to enjoying these. Unfortunately, I took them out after 25 minutes…thinking they HAD to be done. Nope. Raw on the inside. The cooked parts don’t taste very sweet. I used chocolate milk since the other stuff can’t be found.
    Oh well! Perhaps I’ll try again sometime or just look for a new recipe.

    1. All ovens, ingredients, pans, etc. are different so always bake until done in your particular oven and situation – whatever amount of time that means.

      They are not an excessively ‘sweet’ muffin. There is sweetness but more of a rich chocolate taste rather than a ‘sugary’ sweetness. Thanks for trying the recipe.

  3. I made the chocolate zucchini muffins and they were wonderful. I didn’t have the chocolate milk the recipe called for so I just mixed up chocolate ice cream topping with regular milk and it turned out fine. This is a definite keeper of a recipe. Oh, and I didn’t have mini choc chips so I just tossed regular choc chips into a mini food processor and pulsed for a few seconds. Perfect!

    1. Great idea to pulse your regular chocolate chips and that chocolate syrup + regular milk did the trick, too! Glad they were wonderful!

  4. Can this be made in loaf form? I’m sure it will take longer to bake, but I just don’t have the patience for muffin tins today!

  5. Nutchello has been discontinued. :( I looked all over for it and then found out the news from Silk’s Facebook page. Guess we’ll just have to use the dark chocolate almond milk instead.

    1. Dark chocolate milk, chocolate milk, chocolate non-dairy milk, even regular milk will all work. Enjoy!

    1. Some zucchini has more moisture than others. You could always wring out in paper towels before adding to the batter. Otherwise it could be your oven running on the cool side.

  6. Most recipes with zucchini direct the excess moisture needs to be removed before including in recipe. I presume this step is not necessary for this recipe?

    1. I know usually that is the case but for this case, no I did not wring it out. Saves a step and the recipe works just fine that way!

  7. This is the 3rd time ive made the chocolate zucchini muffins in less than one week I absolutely love them !!! My grandson 6 yr old loves them as I am now making a batch as I email you !!! They were a hit with my b friend and his daughter  ! Thank you for sharing your great recipes I also  made the cinnamon Nutella rolls !   So good !!!!!!!!!!!!

    Dolores !

    1. Thanks for trying the recipe and I’m glad it came out great for you, three times in less than a week! Glad this is a hit even with the 6 yr old!

      Great to hear you love the Nutella rolls as well! Keep me posted what else you make! :)

  8. These were delicious! Tasted like brownies! Made with chocolate almond milk and made into mini muffins. Baked 16 minutes. Kids devoured them! Your recipes are always a success! Thank you!!

    1. Thanks for trying the recipe and I’m glad it came out great for you! Thanks for the compliments on my recipes and glad you have success with them!

  9. Just made these because I found your recipe on foodgawker and had extra zucchini left over… they turned out great! I was skeptical when I saw how thin the batter was, but they came out so light and fluffy! And wonderfully moist. I used regular sized chocolate chips because it was all I had and they kind of sank to the bottom, but it made for an extra decadent bottom and I’m not complaining! Thanks for the recipe! 

    1. Thanks for trying the recipe and I’m glad it came out great for you!

      I even wrote in the blog post, trust in the thin batter, it all works out, and see it did :) And yes full size chips will sink but as you said, made for an extra decadent bottom!
