Wednesday, June 2, 2021
Double Chocolate Zucchini Bread recipe is an easy loaf of quick bread to make. Chocolate Zucchini Bread is moist with plenty of chocolate and you'll never feel like you're eating your vegetables. A sliced loaf of Chocolate Zucchini Bread on a great cutting board.

My friend gave me 2 giant zucchinis a little while back so I decided yesterday to use them before they go to waste and made this Double Chocolate Zucchini Bread.

This recipes life altering it's so chocolaty and super moist! It makes 2 loaves since most the time when I make zucchini bread it's with one of those zucchini's that's way to large to eat and this breads one of those that has to be shared! 

Colt just happened to grab the second loaf this morning to take to work and texted me to let me know everyone is in love with it! Not that I had even the slightest doubt! I still have a huge zucchini and a half left so I'm thinking I should make a few loaves to take to the neighbors! 

Who doesn't love a super chocolaty loaf of bread packed with lots of hidden veggies? With 1 1/2 cups of zucchini per loaf I totally didn't feel guilty indulging in a slice for breakfast with my morning cuppa coffee, it was the perfect way to start my day! 

Coconut Oil creamed with granulated sugar and brown sugar in a mixing bowl with an egg added to the center.

Cream together:

  • 1 cup Solid Coconut Oil or Room Temperature Butter
  • 1 cup Granulated Sugar
  • 1 cup Brown Sugar until light and fluffy. 
Add 4 whole Eggs one at a time beating well between each addition.

Note: I have used both butter and the coconut oil, I prefer coconut oil but butter works equally as well.

Creamed Sugar and Coconut Oil with Vanilla Extract, Baking Powder, Baking Soda, and Salt in a mixing bowl.

  • 2 teaspoons Pure Vanilla Extract
  • 2 teaspoons Baking Powder
  • 1 teaspoon Baking Soda
  • 1 1/2 teaspoons Salt 
Mix until well combined.

Creamed Butter with flour, grated zucchini, cocoa powder, coffee, semi-sweet chocolate chips and nuts added to a stainless steel mixing bowl.

  • 3 1/2 cups Whole Wheat Pastry Flour or All-Purpose Flour
  • 3 cups Grated Zucchini
  • 2/3 cup Dark Chocolate Cocoa Powder or Natural Cocoa Powder
  • 1/4 cup Hot Coffee
  • 1 cup Semi-Sweet or Dark Chocolate Chips
  • 1 cup Chopped Nuts (optional)
Chocolate Zucchini Bread batter in a stainless steel mixing bowl.

Stir until well combined and scrape bowl well.

Chocolate Zucchini Bread batter divided between 2 bread pans and topped with chocolate chips.

Divide batter equally between (2)  9"x5"x3" greased loaf pans and sprinkle 1/4 cup Chocolate Chips over each loaf. 

Spread batter into corners and leave center slightly hallowed.

Allow loaves to rest 20 minutes while oven preheats to 350 degrees.

Bake for 60-70 minutes until a toothpick inserted into the center of each loaf comes out clean.

Double Chocolate Zucchini Bread recipe.


  1. How can zucchini bread look to chocolaty and so moist? Amazing!

  2. This is the best looking thing I've seen all day, Serena. Bravo to you and your oven!

  3. What a great idea!! I am a huge fan of chocolate bread and it looks like the zucchini has added a fantastic moistness to it :)

  4. What a wonderful recipe - love that it uses coconut oil. Your Zucchini Bread looks simply divine!

  5. Oh wow - loving this recipe! I can even convince myself that it is healthy - part of my "five a day" fruit and vegetables. Looks so moist and delicious :)

  6. Just made this, wonderful recipe and a great way to use up my vast supply of courgettes!

  7. What temperature do you bake this?

  8. Looks fantastic! Do you suppose that yellow summer squash could be substituted?

    1. I haven't tried it, but I think it would work just fine. It's so similar in texture. Thanks, Serena

  9. Came across your recipe and I had two huge zucchini's. Thar are so big, this recipe only used 1/2 of one! I didn't have coconut oil so used vegetable oil and used 3/4 cup of sugar and 3/4 cup of brown sugar instead. It is amazing! I made just one loaf at a time being burned on recipes before and knowing I modified it. But it did not disappoint! thank you for sharing

  10. Hi - what’s your suggested cooking time for muffins?

  11. Does this cake freeze well? Thanks

    1. Hi Lily, I haven't freeze it before but I have frozen the banana bread which is similar and does freeze really well. It should hold up well to being frozen. Thanks, Serena

  12. I made four of these the other week and they freeze really well, I cut two into slices and froze for quick lunch box cake and the others are whole for gifts or for just eating straight away.

  13. Has anybody made a 1/2 recipe for this for one loaf? I have a couple small zucchini I want to use up and this looks so delicious I want to start now! :)

    1. Hi LQ! This recipe is easy to halve! It should work well! Thanks, Serena

  14. I don’t drink coffee so is there a substitute for that? Do I even have to add it?

    1. You could add hot water or milk. The coffee just helps intensify the chocolate.

  15. I followed the directions exactly but all the chocolate chips migrated to the bottom of the loaves and the cake above was just ok. My husband, who's a huge chocolate and sweets man, gave it a thumbs down, so I won't be making this again. I'm rather sad because it was a great use of zucchini.

  16. I’m wondering if this could be made into muffins? What would cooking temp and time be for that?

  17. what about the amount of one cup? how big are your cups?

    1. Hi! It's a measuring cup! Here's some metric conversions if you aren't US based. Thanks, Serena
