The Only Chocolate Zucchini Bread Recipe You Need

I love sneaking extra veggies into recipes, especially baked goods like this double chocolate zucchini bread. For even more veggies, you have to try my Chocolate Veggie Muffins next.

  • Healthy and nutrient-packed. There’s tons of zucchini bread recipes out there- this one is not only delicious but nutrition-forward too! Each slice has 3 grams of fiber and 5 grams of protein, plenty of zucchini and sweetened with honey instead of refined sugar.
  • Fudgy chocolate flavor. This moist zucchini bread is packed with rich chocolate flavor and it truly tastes like a decadent dessert (it’s more like chocolate zucchini cake, honestly).
  • Perfect for extra zucchini. When you have an abundance of zucchini in the summertime, this is the perfect recipe! It’s my favorite way to use up extra zucchini.
  • Super easy. Unlike other zucchini bread recipes, you don’t have to squeeze out excess liquid from the zucchini for an extra easy recipe.

Ingredients

This recipe comes together with simple ingredients! Be sure to scroll down to the recipe card for the full instructions and ingredients.

  • White whole wheat flour: White whole wheat or “golden wheat” flour is one of my favorite ways to get whole grains in without an overpowering wheat flavor. You can also use regular all purpose flour (white flour).
  • Zucchini: You’ll need shredded zucchini of course! I recommend using the fine side of a box grater because you can barely see the zucchini once it’s baked. You can also use a food processor with a grater attachment.
  • Honey: I use honey but you can also use maple syrup, brown sugar or even coconut sugar.
  • Greek yogurt: Plain Greek Yogurt adds a little bit of protein and helps keep this healthy zucchini bread nice and moist.
  • Eggs: Eggs help hold this bread together for the perfect texture.
  • Oil: Any neutral oil will work. My go-to is avocado oil but any vegetable oil, canola oil, or even melted coconut oil would work.
  • Vanilla extract: This one is my favorite.
  • Dutch process cocoa powder: Any unsweetened cocoa powder will work. I love the rich color and deep chocolate flavor that dutch process cocoa powder creates.
  • Baking soda and baking powder: To help the bread rise.
  • Cinnamon: Cinnamon adds just the right amount of warm spice to balance out the other flavors.
  • Chocolate chips: Regular semi-sweet chocolate chips or mini chocolate chips are my go-to. You can also use dark chocolate chips.

Variations

  1. Chocolate zucchini banana bread. Swap a cup of zucchini for a cup of mashed banana for an easy healthy zucchini banana bread.
  2. Zucchini carrot bread. Instead of 2 cups of zucchini, add 1 cup of zucchini and 1 cup of grated carrots.
  3. Peanut butter chocolate bread. Swirl a few tablespoons of peanut butter into the top of the bread batter before baking.
  4. Add nuts. Add 1/2 cup of chopped walnuts or pecans for some crunch and healthy fats.
  5. Chocolate zucchini muffins. Bake in a muffin pan instead!

Jamie’s Tips

Recipe Tips

  • Choose small to medium zucchinis. Zucchinis that are too big can be bitter and have much more larger seeds.
  • Prep your loaf pan. Make sure to generously grease your loaf pan or line with parchment paper. There’s nothing worse than getting your bread stuck in the pan!
  • Watch the oven. Ovens (and loaf pans) vary, so make sure to keep an eye on your zucchini bread to prevent burning. Start checking for doneness around 48-50 minutes, and then keep checking every couple of minutes after that.

Notes

White whole wheat flour is sometimes also called “golden wheat”. You can also use all regular whole wheat flour, all white flour, or half and half!
For a lower sugar loaf, use just 1/3-1/2 cup of honey. Just keep in mind, it won’t be as sweet and the zucchini flavor will come through more.
