Double Chocolate Zucchini Bread.

This moist and fudgy double chocolate zucchini bread will raise a huge question. How on earth are there vegetables in THIS?!

Moist and FUDGY Double Chocolate Zucchini Bread is so simple to make. And it tastes like chocolate cake!

A story:

Looking for a snack, Kevin poked around the kitchen and unwrapped leftover double chocolate zucchini bread. He grabbed a plate and zapped the piece of chocolate bread for 15 seconds in the microwave. I watched as he opened the pantry, not a word said, and grabbed the peanut butter jar. Opened the drawer for a knife and slathered the warm piece of chocolate bread with creamy peanut butter.

It was at that moment I knew I married the right man.

Alternate titles for today’s recipe:

  • Chocolate Cake Bread
  • Chocolate Bread That is Actually Filled with Vegetables but Tastes Like Brownies
  • Peanut Butter’s Soul Mate Bread
  • Where’s All The Butter and Oil? Bread
  • This Won’t Ruin My Diet? Bread
  • The Only Bread You Will Make For the Rest of the Summer
  • Stop Talking I Need to Eat This!!! Bread

Soooo in other words, this bread is magical. As I mention in my little description above, this incredibly moist, fudgy, double chocolate-loaded bread will have you raising your hand. Um, excuse me. There are vegetables in THIS? Yes. This bread is filled with shredded zucchini and no one will be any the wiser.

It can be our little secret. Muhahaha.

I made this recipe with healthy habits on the brain. Though my blog is filled with chocolate things, caramel swirls, and frosting galore, I actually take healthy eating quite seriously. And I find it much easier to make really, really good recipes that are equally wholesome in the summertime when my favorite produce is at its peak. Hence, today’s bread. (Joey said hence.)

Besides the addition of a green veggie, this recipe has a slew of other notable ingredients. First of all, there is only 1/2 cup of sugar in the entire loaf. I got 9-10 slices out of this loaf which means there is less than 1 Tablespoon of added sugar in each slice. Chocolate chips provide further sweetening, while also creating melty pockets of chocolate throughout each slice. Another ingredient doing double duty is the Greek yogurt. Greek yogurt adds protein, while also tenderizing the bread. I like to use Greek yogurt in some recipes to replace oil because it is low in fat and high in moisture. My secret weapon, if you will.

Chocolate chips. My other secret weapon. ↓ ↓

A little espresso powder makes each slice incredibly rich. Espresso powder or even instant coffee are actually normal ingredients added to chocolate cakes, muffins, cupcakes, and breads. They accentuate the chocolate flavor, making each bite EXPLODE with chocolate. You have to try it. Have to! (Yes, it’s optional if you despise coffee. But you don’t taste coffee!)

The only other thing you need to know about today’s recipe: make more than 1 loaf. This bread will be gone quicker than you can say where’s the peanut butte….

Double Chocolate Zucchini Bread

My piece of advice? Make more than 1 loaf. This bread disappears! Recipe can easily be doubled or tripled or baked in batches.


  • 1 and 1/2 cups (225g) shredded zucchini
  • 1 cup (125g) all-purpose flour(measured correctly)
  • 1/2 cup (42g) natural unsweetened cocoa powder (not dutch process)2
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 teaspoon instant coffee powder (or 1/4 teaspoon espresso powder)3
  • 3/4 cup (135g) semi-sweet or dark chocolate chips4
  • 2 large eggs
  • 1/4 cup (60ml) canola or vegetable oil
  • 1/4 cup (60g) plain Greek yogurt5
  • 1/2 cup (100g) granulated sugar6
  • 1 teaspoon pure vanilla extract


  1. Adjust the oven rack to the lower third position and preheat oven to 350°F (177°C). Spray a 9x5 (or 8x4) loaf pan with nonstick spray. Set aside.
  2. Place the shredded zucchini on a couple paper towels to absorb some (but not all!) moisture. Press a paper towel on top as well. Set aside until step 4.
  3. In a large bowl, whisk the flour, cocoa powder, baking soda, baking powder, salt, instant coffee, and chocolate chips together until combined. Set aside.
  4. In a medium bowl, whisk the eggs, oil, yogurt, sugar, and vanilla together until completely combined. Pour the wet ingredients into the dry ingredients and lightly whisk until combined. Using a rubber spatula or wooden spoon, fold in the zucchini. Pour/spoon batter into prepared baking pan, scraping up every last drop. Trust me, you want it all!
  5. Bake for 45-55 minutes or until a toothpick inserted in the center comes out clean. My bread only took about 46 minutes, but do not be alarmed if yours takes longer. All ovens are different. Allow bread to cool completely in the pan set on a wire rack. Slice and serve when bread has completely cooled. Store leftover bread in an airtight container at room temperature for up to 5 days.
  6. Make ahead tip: Bread freezes well for up to 3 months. Thaw overnight in the refrigerator and allow to come to room temperature before serving.

Recipe Notes:

Double Chocolate Zucchini Muffins: Preheat oven to 425°F (218°C) degrees and spray a 12-count pan with nonstick spray or line with cupcake liners. Prepare batter as directed above, fill each liner to the top with batter and bake the muffins for 5 minutes at 425°F (218°C). Then, keeping the muffins in the oven, lower the temperature to 350°F (177°C) and continue to bake for an additional 14-15 minutes or until a toothpick inserted in the center comes out clean. Makes 10-12 muffins.

Chocolate Zucchini Bread Cupcakes (pictured above): Preheat oven to 350°F (177°C) and line a 12-count pan with cupcake liners. Prepare batter as directed above, fill each liner 2/3 full with batter and bake for 19-20 minutes or until a toothpick inserted in the center comes out clean. Cool then frost with milk chocolate frosting and garnish with mini chocolate chips. Makes 12 cupcakes.

  1. Try using white whole wheat flour or a blend of whole wheat and all-purpose flour! I do not suggest using all whole wheat flour-- the bread may be a little too dense.
  2. Do you remember why you shouldn't use dutch process cocoa? It's because you need the acid in natural unsweetened cocoa powder to help activate the baking soda. Here is my lesson on baking powder vs baking soda.
  3. This little bit of instant coffee or espresso powder accentuates the chocolate SO much. You can't taste the coffee. But you do taste more chocolate. Always a good thing. Keeping this in mind, you can leave it out.
  4. Don't leave these out! They sweeten the bread and give the bread more chocolate flavor. The bread is a little bland without them.
  5. I use low fat plain Greek yogurt. You can use full fat, nonfat, or even vanilla flavor instead. Or even regular yogurt (non-Greek).
  6. For a sweeter bread, use 3/4 cup sugar.

Today’s recipe is adapted from Joy of Baking and this Award-Winning Zucchini Bread. Have you tried it yet?!

Award Winning Chocolate Chip Zucchini Bread

Doubling this recipe is recommended because it ALWAYS disappears!


  1. Sally, this is my second year of making your double chocolate zucchini bread. I prefer to use small loaf pans and give many loaves away as gifts, freeze enough to last through Thanksgiving, and always have a loaf ready for the family snack.
    Well over 100 times, I have used your recipe! Thank you for sharing.
    My favorite time to enjoy a piece of this delicious bread is with my first cup of morning coffee.

  2. So good! I didn’t have paper towels, so just squeezed the zucchini to get rid of the extra moisture.

    Also, I used goat milk yogurt (stronger taste, but still turned out rich and yummy) and topped the finished loaves with fresh, finely grated cinnamon stick. Good thing I tripled the recipe!

  3. Any suggestions for this if I use the shredded zucchini that I have stashed away in my freezer? Thaw and drain all of the liquid? Or just some of the liquid?

  4. I just made this bread using a generic gluten-free flour mix, doubled the recipe, and it came out great! So intensely fudgey and chocolatey, I can’t believe it has less fat/sugar. My coworkers are going to love it!

  5. I made the double chocolate zucchini bread into muffins. Used all whole-wheat pastry flour, replaced the oil with apple sauce and added a 1/2 tsp. cinnamon. My coworkers ate them up!

  6. I’m trying to make this for a friend who eats vegan. Could I use all coconut oil and no yogurt?

  7. I just made the chocolate zucchini bread. Wow…is it ever good! The bread was moist, chocolatey and delicious. I made the full recipe, complete with chocolate chips which by the way are essential. I used a good instant coffee (ground into a powder with mortar and pestle).

  8. I’m making it now by measuring all the ingredients in grams, just found out that for 1 cup of flour, the recipe stated = 125 grams but for chocolate chip is 3/4 cup but = 135 grams…..

  9. Can I use regular coffee instead of instant? We don’t drink instant coffee but I have regular coffee grounds on hand. Can’t wait to make this!

  10. Hello Sally 🙂

    Could I use honey instead of the sugar, and if yes, how much would you suggest?


  11. Can I freeze the cupcakes?  Trying to find school lunch fillers that are healthy and tasty!  If not frozen, they would not last a single afternoon!!! 

    • Absolutely! Up to 2-3 months.

      • These are soooooo yummy!  My VERY fussy husband was not at all impressed when he heard there was healthy zucchinni in them but has been gobbling them up quick smart and can’t believe they are healthy and yummy!  I used stevia instead of sugar and they worked perfectly.  Lovely and moist too!

  12. OMG! Look Tasty should i try to make up for my family. LOVE it 🙂

  13. I just made this bread using a generic gluten-free flour mix, doubled the recipe, and it came out great! So intensely fudgey and chocolatey, I can’t believe it has less fat/sugar. My coworkers are going to love it!

  14. Sally, I am so confident already. You have helped me more than fifteen years of therapy and a company-funded Alaskan cruise ever could. Always in my heart xxo

  15. Hi Sally. Can I substitute honey for the sugar and applesauce for oil?  If so do I need to make any other adjustments to the ingredients or the recipe? 

  16. Made this today in mini-loaf pans! This recipe is perfection <3 <3 <3

  17. hi Sally! is there a way to shred the zucchini fast? i did it manually and its giving me sore neck.

    • Not that I know of besides using a grater!

      • Do you have a food processor with a grater blade? That makes quick work of shredding anything.

      • Hi.
        My Mom has always put the eggs and small cubed zucchini pieces in the blender, pulse it with the “grate” button (or similar of course).
        It takes just a couple of minutes.

  18. I’ve made this using Splenda (a little shy of 1/2 cup), coconut oil  and whole wheat and AP mixed and it was fantastic! I just made this using coconut oil, coconut flour, and coconut sugar. Not as sweet and a slightly more bitter taste but still fantastic! Super moist!

  19. I am just putting a double batch in the oven, I didn’t have instant coffee to add, I used coconut oil instead of canola, I used Stevia and had to add a little more liquid than it called for… I hope they turn out

  20. I would get out of bed for this 🙂

  21. Hi Sally!

    I saw some courgettes in the fridge and knew I had to make this. I’ve alerady baked your healthy zucchini bread and I absolutely LOVE it. I loved this too! Moist and chocolate-y. My sister isn’t a big fan of zucchini bread because she can’t stomach the idea of veggies in cake but she hasn’t figured out that she’s eating veggies in this cake too! Does that make me evil? Thank a ton for this recipe! Oh btw, I substituted the yogurt for homemade sourcream and it was perfect.

  22. I’ve really been wanting to create a chocolate banana bread.   It wouldn’t have the same health benefits as green vegetables but do you think that substituting bananas, in place of the zucchini, might work?   I love the concept of this recipe and feel that a little tweaking may get me to what I was hoping to find.   

  23. Hi Sally loved your recipe!! It was gone in almost a day in my house everyone loved it!! I really want to make it again, but I was wondering if you could substitute the 1/2 cup of sugar for honey or something else? Thanks for all your recipes they are always so fun to make!!

  24. I ran out of semisweet chocolate chips and ended up substituting about 1/4 cup with peanut butter chips – SO GOOD. Thank you for such a great recipe!

  25. Zucchini ? I had know idea you can use that successfully in a chocolate cake, but it sounds amazing and has to be tried soon

  26. Hi Sally
    Absolutely love many of your recipes – thank you for such wonderful ideas!
    Question on this zucchini bread…can I substitute the yogurt for reduced fat sour cream?
    Thanks very much!

  27. This is the second year I will be using this recipe.  I usually make mini loaves and give them to neighbors.  Such a big hit!  Some of the best zucchini bread I ever made.  Thanks so much for the recipe

  28. So sad to see you using a brand of eggs that traps multiple chickens into cages no larger than the size of an iPad. The hens are covered in feces from the cages above them which makes them sick so they are fed antibiotics. Then if one dies (likely from stress and illness) they are left in the cage to rot while the living ones step on them. 

    I would think as someone who loves her pups so much, you would be willing to spend a little more so the animals can actually spread their wings and see sunshine. You can do better, Sally.

    • Thanks Sarah! I have since broken my contract with Eggland’s Best (in July 2016) after learning about the way they treat the animals. Thanks for the reminder to remove their brand name from this recipe post.

  29. Just made this in muffin form. Absolutely delicious! My 9 year old was bracing for the taste of zucchini, but she said she loved the muffins and couldn’t taste the veggies at all. Thank you so much for including weight measurements with your recipes! I prefer to weigh ingredients whenever possible for accuracy/better results. Really appreciate it!

  30. Subs for the sugar? Honey or agave?
