Ingredient Notes

Espresso powder. Adding just a little deepens the cocoa flavor in these muffins. It doesn’t make them taste like coffeee at all.

Shredded zucchini. Use a standard box grater or a food processor fitted with a grating attachment to shred zucchini.

Sour cream. Plain Greek yogurt can be substituted if preferred.

Recipe FAQs

Can I use frozen shredded zucchini in this recipe?

Yes, go ahead and use frozen zucchini. Just make sure to thaw and squeeze out the excess moisture.

Why do you add extra chocolate chips to the top before baking?

A few extra morsels on top make these muffins look even more appealing. You can skip this and fold them right into the batter with the rest, if preferred.

Can this recipe be made gluten free?

We have not tested this recipe with gluten free flour so I’m not sure if it would work. Here’s a wonderful gluten free zucchini muffin recipe if you need one!

How do you store chocolate zucchini muffins?

If you’re not freezing these muffins, you can keep them at room temperature in an airtight container. They stay moist and delicious for several days.

Rich and fudgy Chocolate Zucchini Muffins with double the chocolate! Freezer friendly instructions too!

Ingredients

  • 4 large eggs
  • ½ cup vegetable oil
  • ½ cup sour cream
  • 1 cup granulated sugar
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • 1 cup unsweetened cocoa powder
  • 2 tsp baking soda
  • ½ tsp baking powder
  • 1 tsp kosher salt
  • ½ tsp espresso powder
  • 3 cups shredded zucchini
  • 1 bag (11 oz) semi-sweet chocolate chips, divided

Instructions

  1. Preheat oven to 425 degrees F. Spray two 12-count muffin pans with nonstick baking spray and set aside.
  2. In a large mixing bowl, combine the eggs, vegetable oil, sour cream, sugar, and vanilla until blended. Add in flour, cocoa powder, baking soda, baking powder, salt, and espresso powder. Mix until combined.
  3. Fold in zucchini and 1 ½ cups chocolate chips. Using a large scoop (about ¼ cup batter), fill each muffin tin nearly to the top. Top with remaining chocolate chips.
  4. Bake for 5 minutes. While keeping the muffins in the oven, reduce oven temperature to 350 degree F. Continue baking for an additional 15 minutes. Remove from oven and cool.
  5. If freezing, cool completely. Slide each muffin carefully into a gallon sized ziploc bag (I can fit 9 per bag nicely) and freeze for several months. Place on room temperature counter to thaw overnight (still in bag).
  6. For extra deliciousness, heat muffin for ten seconds in the microwave to give it a warm, fudgy texture!

Notes

  • Adding the Espresso Powder does NOT make it taste like coffee. It just brings out the richness of the chocolate. I use this one from amazon! Recipe can be halved for 12 muffins if preferred. I like to bake extra and freeze for a later date!

Comments & Reviews

  1. Delicious moist chocolate yummy muffins. I used paper liners and the muffins stuck. I’ll just spray the pans next time. Thanks for sharing this wonderful recipe.

    1. Yes definitely squeeze out the extra moisture. You’ll still need a full amount of zucchini for this recipe, so make sure you’re aware of that 🙂

  2. Zucchini, pumpkin and peppermint are the trifecta of fall flavors! These look amazing and I love that these are freezer friendly. Not like delicious things ever last long in my freezer, but I like having that option :). Thanks, Aimee!
