And aside from all of that, it’s so delicious and so easy.

A win, win kind of recipe! And I can’t wait for you all to make it!

I’ve made a few loaves of zucchini bread and zucchini muffins in previous years, but this is my first double chocolate! And wow, it’s so yummy!

What is double chocolate? It just means that instead of a blond loaf of zucchini bread, I made the loaf using cocoa powder and chocolate chips. The more chocolate, the better!

The details

Step 1: grate the zucchini

Here’s the thing, when baking with zucchini it’s really important to remove any of the excess moisture (the water). You’ll want to do this so your baked goods don’t end up super dense and watered down. Simply shred the zucchini and place it in a kitchen towel to squeeze out all the excess water. It’s really easy. The drier you can get the zucchini, the lighter texture your loaf is going to be.

Step 2: make the batter

You just need one large bowl. Mix the wet ingredients: eggs with melted coconut oil, maple syrup (or honey), vanilla, and then the shredded zucchini.

Now add the dry ingredients: whole wheat pastry flour (or white whole wheat flour), cocoa powder, baking soda, instant espresso powder, a touch of cinnamon, and some salt. The espresso really helps highlight the rich chocolate flavors, don’t let it scare you!

Step 4: the chocolate chips

Mix in the chocolate chips or use chocolate chunks! I actually did half and half and loved the way my bread came out.

Step 5: bake

Scoop the batter into a prepared pan, then bake in the oven until it’s just set. This will take around 50 minutes, so you need a little patience for this final step.

Your reward will be delicious warm chocolate, chocolate zucchini bread! Once the bread is out of the oven, you can let it cool or you can enjoy it warm. You all know I’m all about a warm loaf of bread. So after letting this cool in the pan for five or so minutes, I turned it out onto a cutting board and made the first slice.

The bread comes out steaming and smells so good. The sweet hints of vanilla and cinnamon together with the puddles of chocolate are so delicious! It’s soft and moist and just so YUM!

Ingredients

Instructions

  • 1. Preheat the oven to 350° F. Grease a 9×5 inch bread pan.
    2. Lay a clean towel on the counter and spread the zucchini out in an even layer, then squeeze out a little excess water, but don't get it fully dry.
    3. In a large mixing bowl, stir together the coconut oil, maple syrup, eggs, and vanilla until combined. Mix in the squeezed-out zucchini. Add the flour, cocoa powder, baking soda, instant espresso, cinnamon, and salt. Mix until just combined. Fold in the chocolate chunks. 
    4. Pour the batter into the prepared bread pan. Bake for 50-60 minutes, or until the center is just set. If the bread is browning before it's done cooking, cover with foil. Remove the bread and let cool before cutting. Or slice and eat it warm with the chocolate all melty. YUM!

Notes

To Make Gluten Free: Use an equal amount of your favorite gluten-free flour blend in place of the all-purpose flour. I recommend Cup4Cup gluten-free flour
Storing: This bread keeps well for 2-3 days at room temperature. 
Freezing: Cool the bread, wrap well with plastic wrap, then store in a freezer-safe container. Freeze for up to 3 months. Thaw for a few hours on the counter.

    1. Hi Patty,
      Thanks so much for trying this recipe and sharing your feedback, so sorry it was dry! I would maybe reduce the bake time, it sounds like that has worked for others! xT

  1. 5 stars
    Delicious! I used vegetable oil instead of coconut oil because that’s what I had. And because my bread pans are glass, the baking time was about 35 minutes–I should have lowered the oven temp. But it came out perfectly, and is perfectly delicious with a cup of coffee. I will definitely make this again.

    1. Hi Judy,
      Perfect!! Thanks for sharing what worked well for you:) So glad to hear that this recipe was enjoyed! xT

    I love this recipe. It makes me feel like I’m having a delicious chocolate cake for breakfast, and there’s nothing better than that except, perhaps, having it with a good, rich cup of coffee. The only suggestion I’d have is to check for doneness a little earlier than 50 min. For some reason, my loaf was done at 40 min., and it was perfect – any longer in the oven, and it would probably have been dry.

    1. Hi Ginger,
      Happy Monday!! I am thrilled to hear that this recipe turned out well for you, thanks for trying it and your comment!🌼🌸 xx

    Not bad . I thought it would be more moist with the zucchini but it was a little denser than I like but not bad for a deep dem sweet chocolate loaf

    I live in a small town and whole wheat pastry flour is not available. I used regular King Arthur whole wheat and this bread was still delicious! Used a bourbon maple syrup for sweetener and the sweetness was perfect. The zucchini made it moist. I couldn’t wait and ate it warm but I bet it will be even better tomorrow!

    1. Hi Heidi,
      Thanks so much for giving this recipe a try and sharing your feedback, so glad to hear it was a hit! xx

        1. Hi Kimberly,

    I thought they were brownies and realized that it is zucchini bread; how divine is that as it is very good for you. Thank you.

  7. This looks amazing. Would it be possible to use another flour – like Almond or Oat? I need it GF. Thank you

    1. Hi Sharon,
      Yes, that will work well for you! Let me know if you give this recipe a try, I hope it’s delish! xT

    1. Hi Jill,
      Any other neutral oil will work well for you! Please let me know if you have any other questions! xT

  9. I love this recipe! Can we leave out the espresso powder? Can we sub it with instant or ground coffee? Espresso powder isn’t something I usually have on hand! Thanks!

    1. Thanks so much Stephanie!! Sure, instant coffee would also work well for you here! Let me know if you give this recipe a try, I hope it’s delish! xT

      1. Can we substitute another oil for coconut oil? This recipe looks amazing. Can’t wait to make it! Thank you for sharing always the best recipes, too.

        1. Looks like a delicious receipe! Could/Would canola oil be an appropriate substitution for the coconut oil in some proportion?
          Related to cardiac, coconut oil is not on the approved listing of ingredients per cardiology for me.
          Thanks and again the receipe looks amazing!!
