Ingredients
I’m a strong believer in weighing your ingredients for the best baking results. The most accurate way to measure your ingredients is with a kitchen scale. This is why I’ve made it possible for you to view the ingredients on the recipe card by either weight (metric) or volume (US Customary).
Here’s more about some key ingredients in this recipe:
- Zucchini: You’ll need one to two medium sized zucchini for this recipe. Just like with my Healthy Zucchini Muffins with Chocolate Chips, there’s no need to blot the moisture out of the zucchini – you want all that moisture for the recipe.
- All-Purpose Flour: There’s not much flour in this recipe, but just enough to make this a soft, cake-like loaf. Also keep in mind the cocoa powder is another dry ingredient that absorbs moisture too.
- Cocoa Powder: You can use either regular cocoa powder or Dutch-processed cocoa powder. My personal preference is the latter. I love the fudgy, dark chocolate flavor that Dutch-processed cocoa powder yields in this recipe!
- Chocolate Chips: You can use either regular or mini chocolate chips. There’s pros and cons to each. Regular sized chocolate chips give a more prominent burst of chocolate in each bite, but I love how well the mini chocolate chips get incorporated all throughout the loaf. Choose whichever you prefer. I also like to add a handful to the streusel topping. Yum!
- Oil: Use a neutral oil like vegetable, canola, mild olive oil, or melted coconut oil. Oil adds even more moisture and great texture to quick breads.
- Yogurt: Using Greek yogurt in this recipe creates an amazing flavor and fluffy texture. It’s a healthier alternative to sour cream, like in my Peach Cobbler Quick Bread, but with the same yummy results.
- Cinnamon: This spice adds an extra “something” to this bread. It’s ever so slight, but makes all the difference in this chocolate zucchini recipe!
Why bake with zucchini?
Zucchini is a vegetable with a high water content, but doesn’t have a strong vegetable flavor. That makes it perfect to use in recipes where you’re going for a moist and tender crumb!
Zucchini is amazing in a variety of different savory and sweet recipes. You’ll love the moisture it adds to my recipe for Healthy Zucchini Muffins with Chocolate Chips!
Simply grate it with a box grater or the vegetable cutter attachment on your food processor.
How to make Double Chocolate Zucchini Bread
Just like with my other quick breads, I love how easy this chocolate zucchini bread comes together!
- In a large bowl, combine the dry ingredients. Whisk them together and set it aside.
- In a separate mixing bowl, combine the wet ingredients. Whisk them together, and then…
- Add the wet ingredients to the dry ingredients. Mix it together until there are no more dry bits of flour mixture remaining. This will be a thick mixture, almost like brownies.
- Add the shredded zucchini and stir until it’s fully incorporated. There’s no need to blot the zucchini before adding it.
Once the zucchini is mixed in, add the mini chocolate chips. Pour it into a prepared loaf pan. Sprinkle a generous amount of chocolate streusel topping over the loaf.
Look at that amazing chocolate crumb topping! It adds so much yummy extra chocolate flavor and a satisfying crunch to the crust!
- Bake the double chocolate zucchini bread for 50-60 minutes at 350°F. Insert a toothpick or cake tester into the center of the loaf to make sure it’s baked all the way through.
Once it’s baked, allow the double chocolate zucchini loaf to cool in the pan for at least 15 minutes before transferring it to a wire cooling rack. Allow it to cool completely before slicing. I know it’s so hard to be patient when smelling this chocolate bread, but it will slice so much better if you wait until it has completely cooled!
My tips for making Double Chocolate Zucchini Bread
- When making a large loaf, I find it helpful to line the pan with parchment paper and secure it with simple metal clips (they won’t melt in the oven!). This makes it so much easier to lift and remove from the loaf pan.
- I prefer making mini loaves of chocolate zucchini bread for this recipe. Not only do they bake a bit faster, it feels less indulgent if you’re not wanting as big of a slice. Minis are also such a great way to gift a loaf of bread. I package them with these 5×7-inch cellophane bags and tie it with a cute ribbon.
- This recipe will make either one large loaf (9×5-inch loaf pan) or two mini loaves (about 6×3-inch loaf pan). If you make mini loaves, decrease the bake time by 10-15 minutes.
FAQ
You can easily shred zucchini with a cheese grater, like this box grater. You can also use the shredding attachment on your food processor.
There is no need to blot the shredded zucchini before adding it to the recipe. Try to shred the zucchini right before adding it to the mixture – if it sits too long, the moisture will drain from the zucchini and this will change the texture of your bread.
You will absolutely LOVE this super moist, incredibly fudgy double chocolate zucchini bread! It’s the perfect way to get your chocolate fix and eat your veggies at the same time!
My best advice: Double this recipe, because one loaf just won’t be enough!
