Double Chocolate Zucchini Muffins Recipe

If you have some extra zucchinis from your garden because zucchinis are in season right now or you just want to pick up a few extras at the store next time you go, you definitely want to make these double chocolate zucchini muffins!

Zucchini muffins and breads are my favorite things to make when zucchinis are in season, so this recipe (with all the chocolate) is perfect timing.

Although the chocolate may look like the star of this recipe, it’s actually the zucchini that gives them so much delicious flavor, texture and moisture.

How to Make Double Chocolate Zucchini Muffins

My favorite part about this recipe is that you don’t need a mixer. All you need is a bowl and a whisk! Here are the basic steps to making zucchini chocolate chocolate chip muffins: 

  1. Start by whisking all of the wet ingredients together, then add the dry ingredients.
  2. Fold in the chocolate chunks or chocolate chips.
  3. Fill the muffin tins all the way full to the top. You might feel like they’re going to overflow but they will rise really high!
  4. Bake at a high temperature for 5 minutes, then reduce the heat and bake for another 12 minutes.

How to Prep Zucchini for Zucchini Muffins

Shred the zucchini: Start by finely grading the zucchini with a cheese grater. Use a smaller side if you have a few options of shredding size. This recipe calls for 1 cup of shredded zucchini, which ends up being about one small to medium zucchini.

Dry the zucchini: Once it’s shredded, lay the zucchini on a paper towel and dab it dry with another one on top. Allow to dry for 5-10 minutes to get rid of some of the moisture.

Do I Have to Peel the Zucchini?

No, you don’t want to peel the zucchini for these chocolate chip zucchini muffins. Though it might seem like you need to, it actually gets absorbed into the batter because it’s not a super thick skin. Don’t worry about peeling!

Can I Shred the Zucchini in Advance? 

If you want to save some time later on, you can shred your zucchini in advance. Grate the zucchini and dry it on the counter, then place it in an air tight container for up to 5 days before you’re ready to bake.

Tips for Making Chocolate Zucchini Muffins

Add some extra chocolate chips or chocolate chunks to the top of the batter before you put pop the muffins in the oven for some extra appetite appeal!

Also, note that the baking method for these zucchini chocolate chip muffins is a little different than your typical muffin. You’re going to bake them at a higher heat for 5 minutes first. This causes the muffins to rise really high (like the bakery!) and then you’ll turn the temperature down to let them bake all the way through.

Let them cool for a bit and serve them warm! Or cold is good too. You can keep them in an air tight container for up to 1 week.

  • Can I substitute the Greek yogurt for sour cream? Would it be an even swap?

    • Reply
    • Yes, you can make that swap. You don’t want nonfat Greek yogurt though. It’s the fat in the sour cream that makes the muffins so moist and delicious.
