It’s that time of summer where All The Zucchini are ready to be used, and we’re looking for ways to use this green summer vegetable!

I’m happy to tuck shredded zucchini into chicken meatballs or roast them with some tomatoes, but my favorite way to eat zucchini is probably always going to be paired with chocolate. Because yum.

Last year, it was a CRAZY delicious Almond Flour Chocolate Zucchini Cake. This year, it’s Gluten-Free Chocolate Zucchini Bread.

This ultra-chocolatey chocolate zucchini bread is made with an all-purpose gluten-free flour blend so it’s easy to pull together (no need to mix and match flours!), and the end result is fudgy, tender, and perfectly studded with chocolate chips.

Here’s what you need to get started on our easy gluten-free chocolate zucchini bread recipe…

Gather Your Ingredients

Here’s what goes into our gluten-free chocolate zucchini bread:

ingredients for gluten-free chocolate zucchini bread
  • GRATED ZUCCHINI. Grated zucchini makes our gluten-free chocolate zucchini bread nice and moist. I know that’s the grossest word ever, but it’s true! (See the FAQ for a tip for grating zucchini!)
  • EGGS + AVOCADO OIL. Eggs + avocado oil give this chocolate zucchini bread plenty of body and prevent it from getting dry.
  • COCONUT SUGAR + VANILLA. To round out the wet ingredients, you’ll add coconut sugar and vanilla. You can totally use white or light brown sugar if you prefer in your chocolate zucchini bread.
  • DARK COCOA POWDER. To give this gluten-free chocolate zucchini bread that ultra chocolatey look and taste, I use dark unsweetened cocoa powder, sometimes labeled Dutch-processed cocoa or alkalized cocoa powder. Dark cocoa powder tends to be less expensive and easier to find. Dutch processed cocoa is nice if you can find it!
  • GLUTEN-FREE FLOUR. I use a simple 1:1 gluten-free flour to keep things simple. I prefer King Arthur Flour Measure-for-Measure gluten-free flour blend. It’s got a nice mix of flours, no strange taste or smell, and no grittiness. If you use other blends, you may have slightly different results.
  • BAKING SODA + SALT. To finish up the dry ingredients, I add baking soda and salt. This will help the chocolate zucchini bread rise and balance the flavors nicely.
  • CHOCOLATE CHIPS. Aaaaand I love adding plenty of chocolate chips for even more chocolate flavor. A few on the top and plenty inside mean that you’ll get a little chocolate in every bite. Which is exactly how I like my chocolate zucchini bread.

How to Make Gluten-Free Chocolate Zucchini Bread, Step By Step

As always, you can find the full recipe, with ingredient amounts, detailed instructions, and tips in the recipe card below!

making gluten-free chocolate zucchini bread step by step
  1. Preheat & Prep. To start, preheat oven temperature to 350 degrees F. Grease a loaf pan (mine is a 9″x5″ loaf pan) and line with parchment paper.
  2. Combine Dry Ingredients. In a medium bowl, combine flour, baking soda, and salt. Whisk to combine well.
  3. Combine Wet Ingredients. In a large bowl, combine eggs, oil, coconut sugar, cocoa powder, and vanilla. Stir or whisk to combine well.
  4. Add Dry Ingredients to the Wet Ingredients and stir until almost fully combined, with just a few white floury patches left.
  5. Fold In Zucchini & Chocolate Chips. Add grated zucchini and chocolate chips to the batter and fold in until evenly blended.
  6. Bake Zucchini Bread. Pour batter into prepared loaf pan and sprinkle with remaining chocolate chips. Bake at 350 degrees F. for 50-60 minutes, or until a toothpick inserted in the center comes out clean with only a few moist crumbs. (A little melted chocolate chip is ok, but you don’t want any wet batter.)
  7. Cool. Place pan on a cooling rack for about 15 minutes, then run a knife around the edges of the bread and transfer the bread out of the pan and onto a wire rack to finish cooling before slicing. (If you’ve used parchment, you can usually just lift the bread out of the pan using the parchment as “handles.”)
  8. Store leftover chocolate zucchini bread in an airtight container at room temperature 2-3 days, or freeze up to 2 months in a freezer bag.

FAQ + Tips For The Best Gluten-Free Chocolate Zucchini Bread

A TRICK FOR GRATING ZUCCHINI. If you’ve got a food processor, grating zucchini takes less than 30 seconds. Just use the grating attachment, cut your zucchini in half, and get to work! Otherwise, I love this style of grater, which gathers everything up for you nice and tidily.

WHAT’S THE BEST GLUTEN-FREE FLOUR FOR ZUCCHINI BREAD? I recommend using a 1:1 or measure-for-measure gluten-free flour blend for our chocolate zucchini bread. We highly recommend King Arthur Flour’s Measure-for-Measure flour. Our second choice is Bob’s Red Mill 1:1 gluten-free flour blend.

CAN I MAKE THIS WITH REGULAR COCOA POWDER? Yes, though it won’t look or taste *quite* as chocolatey. You can find dark cocoa powder at lots of regular grocery stores, or you can order Dutch-processed cocoa here.

HAVE YOU TRIED THIS WITHOUT EGGS? I haven’t yet. I’d probably start with flax eggs or powdered egg replacer if I were going to try a substitute.

HOW DO YOU STORE LEFTOVER CHOCOLATE ZUCCHINI BREAD? With most gluten-free baked goods, I prefer to put them in the refrigerator or freezer. This will keep in the fridge 2-3 days and in the freezer for about a month. (I like freezing it cut in slices so I can pull one out at a time.)

  • 1/2 teaspoon salt
  • 1/2 cup chocolate chips (2-3 Tbsp. set aside)

Notes

  • Oil. You can use canola oil, melted & cooled coconut oil, melted vegan butter, or melted butter.
  • Gluten-Free Flour. We recommend King Arthur Flour Measure-for-Measure Gluten-Free Flour for this recipe. Our runner up is Bob’s Red Mill 1:1 gluten-free flour. If you use another brand, be sure it contains xanthan gum, or the zucchini bread will not turn out properly. Do not substitute almond flour or coconut flour here as they will not work in this recipe. 
  • Zucchini. There’s no need to squeeze extra liquid out of the zucchini for this recipe. You can just wash it, trim off the ends and grate it!

    The bread was amazing! So chocolately and moist. It was almost like eating chocolate cake. We had friends over and I served this for dessert and they loved it. A great way to put a dent in the over abundance of zucchini 😊

    Took this to a function so they would have a gluten free option. It was a hit. I “save” a lot of recipies but print few. Printed this one!

  3. 5 stars
    Used coconut oil and half coconut sugar, half brown sugar. Delicious! Thank you! Will definitely be making again!

    1. Hi Melanie! The macros are based on 12 slices. I haven’t weighed the individual slices, but if you cut into 12 even slices, 1 slice = 1 serving.

    I had so much zucchini I made two loaves. One barely made it to cool completely and the other I had to hide so it could cool and I could freeze it for later! My three teen devoured the first loaf!

  5. 5 stars
    This was absolutely delicious! I had olive oil on hand, so I subbed that for the avocado. Otherwise I followed the recipe, and my kiddo and I both loved it. 😋

  6. 5 stars
    Made this for my GF daughter and family – they LOVED it. This was super moist and choclatey and uncomplicated to make. This is a winner for family and guests – you can’t go wrong.

    Made this for my sister who was advised to go gluten free, recently. I used a different brand of flour alternative, than those mentioned. Only because those were not available at the store on the day I was shopping. I did use avocado oil, the Dutch processed cocoa, etc. per the recipe. I baked in a dark loaf pan for 60 minutes, I checked at 50 minutes. It was still not ready and at 60 minutes was perfect. Honestly this was very delicious, not at all a “gluten-free” good enough kind of quick bread!
