Ingredient Notes

Ingredients needed for double chocolate zucchini bread.

Espresso powder. If you’re unfamiliar with this secret ingredient, it’s essentially a highly concentrated powdered coffee. While it doesn’t give the bread a coffee flavor it does enhance the richness of the cocoa.

Sour cream. We use sour cream in many of our quick bread recipes. It keeps things moist while adding delicious flavor. Unsweetened Greek Yogurt can be substituted if you prefer.

Zucchini. Shred the zucchini with a box grater before adding it to the batter. No need to peel it first.

Vanilla Extract. Choose a pure vanilla (not imitation) or make our delicious homemade vanilla extract recipe!

Easy Instructions

Combine wet ingredients.

Stir together the oil, eggs, sour cream, sugar and vanilla.

Add dry ingredients.

Mix in the flour, cocoa powder, baking soda, baking powder, kosher salt and espresso powder. Fold in the zucchini and 1.5 cups worth of semi sweet chocolate chips.


Divide the batter into two greased loaf pans. Sprinkle the rest of the chocolate chips on top.

Bake Double Chocolate Zucchini Bread for about 45 minutes. Let the chocolate zucchini bread cool completely before eating or freezing

Tips and Tricks

  • How to prevent loaves from sticking. Place a rectangle of parchment paper at the bottom of each loaf pan. Then, spray with baking spray before adding the zucchini bread batter. If you don’t have parchment paper, then grease the pans generously! Use my easy cake release recipe.
  • How to freeze. Wrap baked loaves in foil. Then slide them into freezer safe gallon sized bags. Thaw in the bag overnight on the counter when ready to serve.
  • Make Muffins! Try our chocolate zucchini muffins for a fun and portable breakfast.
  • Nut variations. Chopped walnuts and pecans would be a delicious addition to this bread.
  • Love chocolate? Try our chocolate chip banana muffins next!

Recipe FAQs

Does the espresso powder make the bread taste like coffee?

It doesn’t give the chocolate zucchini bread any coffee flavor. I promise. Espresso powder brings out the natural richness of the chocolate. Taste it and you’ll see!

Can I use frozen shredded zucchini in this recipe?

Yes, frozen zucchini works perfectly here. Thaw the zucchini and squeeze out any excess water before adding it to the batter.

Can I use milk chocolate chips instead? How about white chocolate?

Yes and yes to ALL chocolate chips in this bread! I happen to love the classic semi-sweetness in my double chocolate zucchini bread.
Feel free to experiment with different chocolate chips to find your favorite. You could even combine them for a fun twist.

  • Preheat oven to 350 degrees F. Line the bottoms of two 9-inch loaf pans with parchment paper and spray with baking spray. Or grease both pans generously.
  • 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.

Comments & Reviews

  1. I have made this bread 2X in the past couple of weeks. It is moist, rich and has a heavenly chocolate flavor. I love the moistness of this bread. I have shared the recipe several times after telling people about it. I even fooled my son, not telling him it had zucchini in it and he loved it. Thanks Aimee for all the delicious recipes. My recipe box is overflowing with SugarySweets recipes!

  2. Thanks a lot for sharing this amazing double chocolate zucchini bread recipe! It tasted amazing and delicious! Highly recommended!

    You had me at double chocolate!! Always love this bread. The zucchini makes it so moist. There’s never anything left!

  5. 5 stars
    My family could not tell at all that this recipe had zucchini! That’s a huge win in my book. I love the flavors.

  6. I’d like to make this Weight Watcher friendly. I saw the Greek yogurt substitution. How about applesauce for the oil & stevia for the sugar? Do you think it would work? And what are use the same amounts?

  7. I made this , delish. I like that the total sugar in each loaf was 1/2 cup! Thank you for the recipe, I will make again!

  8. If using fresh zucchini, do I need to squeeze out the liquid? Whenever I grate fresh zucchini, there’s always a lot of water. Your directions only discuss what to do if using frozen zucchini.  Thanks!

    1. My fresh zucchini is pretty dry. If you find it to be extra moist, then yes, I would squeeze out the extra liquid 🙂

  9. You are the Zucchini Queen! I cannot believe all of the wonderful recipes you have developed, especially that meatball one. I wish my Italian Wedding Style canned soup had some of those in there. My grandmother used to bake my family a loaf of zucchini bread every fall and I thought it was so delicious. I must admit, I have only Home-Ec baking skills from the 10th grade, but this chocolate loaf is so utterly enticing. Maybe I ought to try your Mom’s recipe first.

  10. Wow this looks like so much chocolatey goodness! I still have zucchini that needs to be used. This is a great recipe to use them!

  11. Oh I love zucchini season and plant ‘zuccs’ every year. They are one thing that I can always rely on doing well in the garden. Sadly, this year they have rebelled and I don’t have very many. I guess I have to buy my zucchini at the grocery this year. The bread looks amazingly moist and delicious
