Erin’s Recipe Rundown

Texture: Moist, tender crumb with rich chocolate chips.
Taste: Fudgy chocolate flavor with hints of zucchini.
Ease: Easy beginner-friendly quick bread recipe!
Top Tip: Zucchini has a high water content. To get the best texture, finely grate it and then lightly squeeze out the liquid before using.
Recommended GF Flour: Use a high-quality flour that contains xanthan gum. I like King Arthur Gluten-Free Measure-for-Measure Flour and Bob’s Red Mill Gluten-Free 1:1 Baking Flour.
Would I make these again? 100% yes! This easy gluten-free double chocolate zucchini bread is decadently chocolatey and a delicious way to use up summer zucchini. It makes a delicious snack or dessert!

Ingredients You’ll Need
Here are a few notes on some of the key ingredients to make this gluten-free double chocolate zucchini bread. Jump to the recipe card below for the exact measurements.

- Gluten-free flour: For the best texture, use a high-quality flour that contains xanthan gum. I recommend King Arthur or Bob’s Red Mill.
- Grated zucchini: Use the smallest holes on a box grater to finely shred the zucchini. Be sure to gently squeeze out the excess liquid before measuring too. This step is crucial for achieving the right texture!
- Sour cream: I often use full-fat sour cream in my recipes because it helps create the most tender crumb.
How to Make Gluten-Free Double Chocolate Zucchini Bread
Here’s an overview of how to make this recipe. You can jump to the recipe for the full instructions!

Start by shredding and squeezing the zucchini, then set it to the side. In one bowl combine the dry ingredients, in another combine the wet ingredients. Add the grated zucchini to the wet ingredients, then combine the two bowls using a rubber spatula.
This recipe makes one 9×5-inch loaf. Pour the batter into the prepared pan and bake. The toothpick test is the best way to judge if it is baked through. Let it cool in the pan for 5 minutes, then remove it from the pan and let it cool on a wire rack. Enjoy!

Super easy to make and very delicious. I tested it out on several friends who all said they couldn’t tell it was gluten free. Now a favourite of mine.

Is there a substitute for sour cream in this chocolate zucchini bread .
Hi Sandra, dairy-free sour cream or dairy-free yogurt can be used in place of the sour cream. We hope you enjoy the recipe!
So easy, SO very yummy. Already making a 2nd loaf to share.
Yay! We’re so pleased you loved the new recipe so much! Thank you for your kindness.
I was wondering if I can bake as muffins instead, it soo hot and having oven on for almost hour, I like to cut down baking time if possible, I really what to make this recipe??
Hi Dorrel, yes that should work! We’d guess 18-22 minutes will work for muffins (same temperature), but keep a close eye on them and use a toothpick to confirm if the centers are baked through. We’d love to hear how it goes!
