Double Chocolate Zucchini Bread

The massive zucchini rush (too bad it’s not a gold rush, right?!) has slowed down in the garden, but I’m still picking at least one every couple of days. That’s more than enough zucchini to eat and still have some left for baking experiments! I’ve done my fair share of zucchini bread, from a traditional version, to my grandma’s recipe with pineapple, walnuts and dates, and even zucchini cornbread. While I have seen tons of recipes for zucchini bread fused with chocolate, I just couldn’t wrap my head around it. Believe it or not, given my disdain for most vegetables, I actually like zucchini bread… And we all know I positively love chocolate, but for some reason I just couldn’t envision these two worlds mashing together in a positive way. It’s a good thing I got desperate with the zucchini that was sitting around and wanted to try a new recipe, or else I wouldn’t have finally given in to the chocolate and zucchini marriage. I definitely went into this recipe skeptical and was proven way wrong on all accounts. This bread is utterly amazing – it’s rich, sweet, moist and oozing with chocolate flavor. I am a skeptic no more. Bring on the chocolate zucchini goodness!

I had been poking around for a chocolate zucchini bread recipe for awhile before stumbling across this one. My mom said she remembered my grandma making some chocolate zucchini loaves on a few occasions, but we couldn’t find an actual recipe. I found a few others online that didn’t look quite chocolate-y enough for my very high-maintenance (read: like a 5-year-old’s) taste buds, and then last week this beauty popped up in my Google reader. I always love to see what the folks over at King Arthur Flour are baking up since they’re my favorite stop for ingredients and baking tools, and they knocked it out of the park with this bread. The chocolate flavor is deep and rich, the bread stays moist thanks to the zucchini, and the chocolate chips give it an extra oomph of chocolate flavor and really add to the texture. Almost everyone who tasted this agreed that it tasted like an incredible piece of chocolate cake. We even sliced some for dessert and topped it with vanilla ice cream! You could also go the route of my Double-Chocolate Loaf with Peanut Butter Cream Cheese Spread and eat it for breakfast. Both are perfectly acceptable serving options in my book!

Can I still claim that I’m eating my veggies when my veggies are baked into a vat of chocolate? I say yes! :)

Double Chocolate Zucchini Bread

Yield: One 8x4-inch loaf

Prep Time: 15 minutes

Cook Time: 65 to 75 minutes

Total Time: 1 hour 30 minutes


1 & 2/3 cups all-purpose flour
1/3 cup Dutch-process cocoa powder
1 teaspoon salt
½ teaspoon baking powder
½ teaspoon baking soda
2 eggs
½ cup vegetable oil
½ cup light brown sugar
1/3 cup honey
1 teaspoon vanilla extract
2 cups shredded zucchini
1 cup semisweet chocolate chips


1. Preheat oven to 350 degrees F. Grease and flour an 8x4-inch loaf pan; set aside.

2. In a medium bowl, whisk together the flour, cocoa powder, salt, baking powder and baking soda; set aside.

3. In a large bowl, whisk together the eggs, vegetable oil, brown sugar, honey and vanilla extract. Add the flour mixture to the wet ingredients and use a rubber spatula to gently fold the batter together until almost no flour remains. Stir in the zucchini and chocolate chips, ensuring they are evenly distributed.

4. Pour the batter into the prepared loaf pan and bake for 65 to 75 minutes, or until a toothpick (or thin knife) inserted into the center comes out with just a few moist crumbs attached. Allow to cool in the pan for 15 minutes, then turn out onto a cooling rack to cool completely before slicing. Store leftovers at room temperature, tightly wrapped in plastic wrap.

    I love zucchini in baked goods! Although…the chocolate part of this recipe is definitely what appeals to me most :)


  2. Kristen on July 17, 2012 at 12:55 am

    Sounds interesting. I’m not a big zucchini fan but the chocolate might be enough to convince me to try it.


    • Betty G on July 8th, 2014 at 1:14 pm

      I hope you already tried it, since we’re on the same road.
      I baked it yesterday night and brought some slices to the office today. Total success!


  3. Ashley @ Wishes and Dishes on July 17, 2012 at 1:16 am

    I was just thinking about trying a zucchini bread today and I see this! I like the chocolate version :)


  4. Angelyn on July 17, 2012 at 2:26 am

    This looks amazing!!!


  5. Victoria on July 17, 2012 at 3:17 am

    Oh my goodness!! Double chocolate zucchini bread is one of my favorite foods on the planet!! So glad you tried it!! I glaze mine with an orange glaze…out of this world! Thank you for the recipe, I love KAF!


  6. Jessica on July 17, 2012 at 5:13 am

    This loaf looks positively scrumptious. I have never tried making OR eating chocolate and zucchini together! This is now on the top of my “must make” list. I will be posting the results on my blog soon. Please visit if you have a moment! Thank you!


  7. IdaBaker on July 17, 2012 at 5:28 am

    I’m not sure if it was because I was raised with zucchini bread or not, but the minute it is mentioned, I’m ready to head to the kitchen.

    Two of my favorites in one bread makes this even better. :)


  8. Jennifer @ Peanut Butter and Peppers on July 17, 2012 at 7:14 am

    I haven’t had zucchini bread in over a year, I have to make it!


  9. Katrina on July 17, 2012 at 7:40 am

    Mmm perfect for breakfast!


  10. Susan on July 17, 2012 at 8:23 am

    I get email updates from King Arthur Flour and when I saw this recipe, I immediately had to try it. While, it was moist and a deep chocolate, it wasn’t sweet enough for me. It seemed a little bitter. I think it needed an addition of white sugar. Or, maybe I did something wrong.


  11. shelly (cookies and cups) on July 17, 2012 at 9:24 am

    I may or may not have 14 zucchini sitting on my counter right now.
    Must make this!


  12. Jennifer on July 17, 2012 at 9:36 am

    This looks fantastic! I love zucchini bread, and I love chocolate. Win!


  13. Ali @ Gimme Some Oven on July 17, 2012 at 9:36 am

    Mmmm…I always end up making a few loaves with surplus zucchini. The double chocolate sounds perrrrrfect!


  14. Jessica@AKitchenAddiction on July 17, 2012 at 10:14 am

    Yum!! I love zucchini bread and chocolate never hurts! :)


  15. sally @ sally's baking addiction on July 17, 2012 at 11:09 am

    I’ve never baked or tasted zucchini bread before! But something tells me I’m missing out. The deep and rich chocolate flavor of this bread has me sold!


  16. colleen @ Secrets fromthe Cookie Princess on July 17, 2012 at 11:23 am

    I’ve been looking for a go to chocolate zucchini bread recipe. This might be it!


  17. Mi Vida en un Dulce on July 17, 2012 at 11:24 am

    I have several problems with zucchini and my kids. Why is so difficult for kids eat something green? I tried with muffins, breads, cupcakes, and no one give me a result. But what if I mixed it with chocolate? Who can resist to chocolate? Maybe that is the key. I will try with your recipe.


  18. caralyn @ glutenfreehappytummy on July 17, 2012 at 11:43 am

    oh yum! i could go for a slice right now!


  19. Nancy @ CouponClippingCook on July 17, 2012 at 12:03 pm

    What a great way to get your daily veggies! And love that chocolate is involved. YUM.


  20. Mollie on July 17, 2012 at 12:37 pm

    I grew up on chocolate zucchini bread and LOVE it. I just made an apricot zucchini cake – sounds like another weird combo but works GREAT!


  21. Riley on July 17, 2012 at 4:38 pm

    I can’t get enough of zucchini bread… Or chocolate! This looks amazing!


  22. April on July 17, 2012 at 7:32 pm

    This is going on my list! Also wondered, have you tried making the Pumpkin Bread in the latest issue of Cooks Illustrated?


    • Michelle on July 28th, 2012 at 3:18 pm

      Hi April, I have not made it yet, but will definitely do so this fall!


  23. Jessica on July 17, 2012 at 7:38 pm

    I can’t wait to try this – I’ll just have to not mention the zucchini part to my hubby and daughter! Yummy:)


  24. Spencer on July 18, 2012 at 12:59 am

    Looks delicious! I love the combination of chocolate and zucchini so I know I would love this!


  25. Jenny on July 18, 2012 at 10:38 am

    I made this last night and its so good! My very picky 9yr old ate it up!


  26. SnoWhite @ Finding Joy in My Kitchen on July 18, 2012 at 11:41 am

    This is quite similar to our family recipe — only we use dark chocolate – yum. I love how moist zucchini makes bread! We’re just starting zucchini season here & I’ll be looking forward to many loaves of bread.


  27. Transportation Services Chicago on July 18, 2012 at 11:56 am

    This looks AMAZING!!!


  28. Quicha on July 18, 2012 at 5:01 pm

    I made this today. Delicious! It came out a little overdone even though I didn’t even bake for the minimum amount of time as indicated in the recipe – all thanks to my electric oven. :( Any suggestions on baking in an electric oven?


    • Michelle on July 28th, 2012 at 3:27 pm

      Hi Quicha, I would recommend getting an oven thermometer so you can be sure of the exact temperature. Your oven might be set at 350, but the temperature could actually be 375 or even 400! Also, if you’re using a dark non-stick loaf pan, decrease the oven temperature by 25 degrees (do this for any recipe where you’re using a dark non-stick pan).


  29. Tracey on July 18, 2012 at 9:31 pm

    The very first thing I ever baked with zucchini was a chocolate cake from KAF, and I expected it to be gross, but it was amazing. I bet this bread is just as good, I’m so excited to make it!!


  30. Lori on July 19, 2012 at 10:23 pm

    I love chocolate zucchini cake. The first time I made it I had bought a zucchini for a weight watchers soup recipe. After ONE day on weight watchers, I said the heck with that and made chocolate zucchini bread instead. Your version sounded great with the honey in it, so I just made it to take to work tomorrow. It smells so good I don’t know if I will be able to share it :)


  31. Jen @ My Kitchen Addiction on July 20, 2012 at 7:26 am

    Between the garden and our CSA, I am still up to my ears with zucchini. I was just thinking I wanted to try some new zucchini bread recipes, and this one certainly sounds like a winner. Yum!


  32. Jodi on July 21, 2012 at 1:51 pm

    I made a loaf this morning, it’s so good!!


  33. Anna on July 21, 2012 at 5:27 pm

    I’ve been paring down on my feeds lately, and yours is one of the few blogs I kept on my list. All the recipes are very good and this bread is to die for. I started making it at 9 pm (Europe) thinking of having it for breakfast. It’s past midnight now and all there’s left is one slice – and it’s mine, mwahahaha!


    • Michelle on July 28th, 2012 at 4:02 pm

      Hi Anna, So glad you kept me around! :)


  34. Nicole on July 23, 2012 at 10:44 am

    Made this to bring to my parents on the farm this weekend. SOOOO good.


  35. LisaG on July 24, 2012 at 7:40 am

    I’m gonna try this one :)

    My usual is a chocolate zucchini layer cake with cream cheese icing- I also make it in a 9″x13″ sheet or cupcakes for work. (stealth zucchini off-loading)

    But this one looks like I could pass it off at breakfast on the weekend – whoo-hoo!


  36. Dee on July 25, 2012 at 1:58 pm

    I have been stalking your site and bookmarking recipes to make whenever I have time. I baked this bread and it’s so good. It got a thumbs up from all family members — including two three year olds! Love it – not too sweet and just the right amount of ‘chocolateyness’ !! Thanks so much for all of your recipes!


  37. Dave Wioodworth on July 25, 2012 at 11:37 pm

    Who knew chocolate and zucchini would mix? I usually send my baked goods off to work with my wife so (I don’t sit home all day and eat!) but this bread I had to save for myself. Luckily it freezes well!


  38. Dee on July 27, 2012 at 2:30 pm

    While I wouldn’t exactly call this bread, HAHA! More like cake, I made today, I had to slice it into 12 slices so I can justify the calories. HAHA! Phenomenal taste.


  39. Elise on July 30, 2012 at 10:52 am

    I made this bread last night and I didn ‘t tell anyone it had zucchini in it until after they had tried it and even my 7 year old son said “Mom this Bukinni is so yummy!” The adults were all very surprised and asked for seconds. I will be using this recipe again I’m sure!


  40. Emilie @ Emilies Enjoyables on August 2, 2012 at 3:03 pm

    Made this and it was a huge hit! So chocolatey!


  41. Lulu on August 5, 2012 at 2:25 am

    thank you for a great cake! easy to make, moist and yummy and OH SO CHOCOLATeY!!! love it


  42. Rachael Pifer on August 7, 2012 at 12:56 pm

    This sounds like a great receipt. I cant wait to try it! My question to you is since i’m a new baker is there a way to use applesauce or greek yogurt instead of some of the other ingredients? To make it a little healthier? I have made lots of things with subs but wasn’t sure which ingredients to sub or if it was even worth trying to change the receipt in any way and still get a great loaf


    • Michelle on August 9th, 2012 at 4:31 pm

      Hi Rachael, You could use applesauce (I would use unsweetened) in place of the vegetable oil in this recipe.


  43. Susan on August 29, 2012 at 12:07 pm

    I’ve made this porbably 4 times this summer!! LOVE.


    • Susan on August 29th, 2012 at 12:08 pm

      Oops. “Probably.” Good thing I bake better than I type : )


  44. Marie on September 18, 2012 at 11:12 pm

    This was fabulous!! I doubled the recipe cuz I got lots o zucchini. We only put in half of the chocolate chips and it was still fabu! Thanks so much!


  45. Carol on August 5, 2013 at 7:30 am

    I tried this recipe yesterday, kinda late I know but the result (according to my friends and family) was great but I thought that I missed something especially after looking at your photos again. Your recipes are really helping me improve my baking skills….thank you all the way from Kenya.


  46. Livia on August 23, 2013 at 2:45 am

    Would love to try this recipe! But howmany zucchinis aprroximately do we need to make 2 cups?


    • Michelle on August 23rd, 2013 at 5:49 pm

      Hi Livia, It really depends on how large the zucchini is. One large zucchini could yield you 2 cups, but it just depends on the size.


  47. robin byrd on August 29, 2013 at 6:19 pm

    This looks really good. I will defininately have to make this. I love the combination of zucchini and chocolate. My mother always makes zucchini chocolate chip cookies that are to die for!


  48. Krysti on September 4, 2013 at 12:20 am

    Turned out great. Yum!


  49. Ilona on September 19, 2013 at 9:20 am

    I baked this today. Yummy! And sooo easy! :)


  50. Cassie on July 12, 2015 at 10:02 am

    I made this!! It was 20 minutes from being done, it was 2:00 in the morning, and i looked at the counter to see- to my frustration- an untouched bottle of sunflower exasperation i turned off the oven and went to bed, leaving the bread in. I whispered to my husband ‘the bread is ruined’. But i woke up the next morning to find him happily eating a slice! Not bad!! In fact pretty darn good! I made another today with the oil to compare… Update to come!
