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.

To intensify the chocolate flavor, I used Silk Dark Chocolate + Walnut Nutchello (note: this product is no longer available. I’ve shared substitutions for this ingredient in the recipe card below). Between the Nutchello, cocoa powder, and mini chocolate chips, you’ll be in triple chocolate heaven.

I recommend using mini chocolate chips because they incorporate better and ensure that every bite is pure chocolate bliss. The layer of mini chocolate chips on top makes these some of the best muffin tops ever.

For those of you who enjoy baking science, the vinegar (an acid) reacts with the baking soda to create carbon dioxide, and the result is a lighter, more tender crumb much in the way that buttermilk (an acid) would react.

Trust the boiling water and thinness of the batter. It reminds me of what I did in my Slow Cooker Hot Fudge Cake, which, like these chocolate zucchini muffins, is a keeper.

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? 

If you can’t find Nutchello at your local grocery store, 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 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.

Yield: 13 muffins

Prep Time
10 minutes
Cook Time
20 minutes
Total Time
30 minutes


  • 1 cup finely grated zucchini, measured loosely laid and not packed in the cup (from about 1 medium zucchini)
  • 1 cup all-purpose flour
  • 3/4 cup granulated sugar
  • 1/3 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt, or to taste
  • 1 large egg
  • 1/2 cup Silk Dark Chocolate + Walnut Nutchello (Silk Soy, Almond, or Coconutmilk, or chocolate milk, may be substituted)
  • 2 teaspoons white vinegar
  • 1/4 cup canola or vegetable oil
  • 1 teaspoon vanilla extract
  • 1/2 cup boiling water
  • 1/2 cup semi-sweet mini chocolate chips
  • about 12 teaspoons semi-sweet mini chocolate chips, divided


  1. Preheat oven to 350F. Line a 12-Cup Regular Muffin Pan with liners; set aside.*
  2. Grate the zucchini on the fine blade of a box grater; set aside.
  3. To a large bowl, add the flour, sugar, cocoa powder, baking soda, salt, and whisk to combine; set aside.
  4. To a medium bowl, add the egg, Nutchello, vinegar, oil, vanilla, and whisk to combine.
  5. 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.
  6. Add the zucchini and stir to combine.
  7. Add the boiling water and stir to combine. Batter will be thin.
  8. Add 1/2 cup mini chocolate chips and stir to combine.
  9. 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.
  10. Evenly top each muffin with a generous pinch of mini chocolate chips, about 1 teaspoon per muffin.
  11. 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.


*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.
