This indulgent chocolate zucchini bread is my go-to treat when I want something rich but not overly sweet You would never guess that a generous helping of shredded zucchini is nestled inside giving it a beautifully moist crumb and a touch of wholesomeness It is the ultimate trick for getting veggies into dessert without anyone being the wiser

When my family first tasted this bread during a rainy weekend baking spree nobody could believe that zucchini was the secret ingredient Now it makes a regular appearance any time we are craving a chocolate fix

Ingredients

  • Large eggs: provide structure and moisture Pick eggs with sturdy shells for freshness
  • Neutral vegetable oil or melted butter: keeps the loaf tender Use a mild oil for the cleanest flavor
  • Sour cream or plain Greek yogurt: adds tang and plushness The fattier the better for richness
  • Light brown sugar: gives moistness and a rounded sweetness Make sure no hard clumps remain
  • Granulated sugar: for balanced sweetness and texture Look for very fine granules if possible
  • Vanilla extract: boosts the chocolate flavor Use pure extract for best results
  • All-purpose flour: gives substance to the loaf Sift if yours tends to be lumpy
  • Natural unsweetened cocoa powder: delivers chocolate intensity Choose a fresh and fragrant variety

Step-by-Step Instructions

Prepare the pan:
Line a metal loaf pan with parchment paper or spray very well with nonstick cooking spray This ensures easy removal and prevents sticking
Combine wet ingredients:
In a large measuring jug thoroughly whisk eggs oil sour cream brown sugar granulated sugar and vanilla together until totally smooth Hunt down any lumps of sugar so the batter bakes evenly
Mix dry ingredients:
In a roomy bowl whisk flour cocoa powder baking powder baking soda and salt together Be meticulous so the leaveners and cocoa are evenly distributed

Add the shredded zucchini to the dry mixture Use a rubber spatula to gently toss until zucchini is well coated with flour mixture Fold in the chocolate chips evenly
Make the batter:

Recipe FAQs

→ Why add zucchini to a chocolate loaf?

Zucchini brings extra moisture and a tender crumb, blending seamlessly with chocolate for a rich texture without a noticeable flavor of vegetables.

→ How do I prevent the loaf from being too dense?

Gently fold the batter and avoid overmixing once wet and dry ingredients combine. This ensures a light, fluffy texture.

→ Can I use Greek yogurt instead of sour cream?

Yes, plain Greek yogurt makes a great substitute for sour cream, keeping the loaf moist and adding a slight tang.

→ Which type of chocolate is best for this loaf?

Milk or semi-sweet chocolate chips or chunks work well. You can use a mix or choose your favorite for the best flavor profile.

→ How should this loaf be stored?

Store cooled bread loosely covered at room temperature for up to three days, or freeze for up to three months after wrapping well.

→ Can I bake in a different pan size?

Standard 4×8 or 5×9 inch loaf pans work best, but you can adjust baking time if using another size or material. Check for doneness with a toothpick.

Yield: 10 Servings (10 slices)

Dietary Preferences: Vegetarian

Ingredients

01 2 large eggs
02 ⅓ cup neutral vegetable oil or melted butter
03 ¼ cup sour cream or plain Greek yogurt
04 ½ cup light brown sugar
05 ¼ cup granulated sugar
06 1 teaspoon vanilla extract
07 1 cup all-purpose flour
08 ½ cup natural unsweetened cocoa powder
09 1 teaspoon baking powder
10 ¼ teaspoon baking soda
11 ¼ teaspoon salt
12 1 ½ cups shredded zucchini (about 1 medium or just under ½ pound)
13 ¾ cup chocolate chips or chunks (milk or semi-sweet, plus more for garnish if desired)

Steps

Step 01

Heat oven to 350°F. Line a 4×8 or 5×9 inch loaf pan with baking parchment or spray well with nonstick cooking spray.

Step 02

Using a whisk, blend eggs, oil, sour cream, brown sugar, granulated sugar, and vanilla extract in a large measuring jug until combined, breaking up any lumps of brown sugar.

Step 03

In a large bowl, whisk together all-purpose flour, cocoa powder, baking powder, baking soda, and salt.

Step 04

Using a rubber spatula, fold shredded zucchini into the flour mixture, ensuring it is evenly distributed. Add chocolate chips and fold them in as well.

Step 05

Pour the wet ingredients into the dry ingredients. Using a rubber spatula, stir just until combined and no dry flour is visible. Do not overmix.

Step 06

Pour the batter into the prepared pan. Sprinkle with additional chocolate chips if desired. Bake at 350°F for 45-55 minutes, until the top is risen and a toothpick inserted into the middle comes out clean. Cover bread with foil after 25-30 minutes if the top gets too dark.

Step 07

Once baked, remove the pan from the oven and let it rest on a cooling rack for 5-10 minutes. Remove the bread from the pan, peel off parchment, and let it cool completely on the rack before slicing.

Notes

  1. Use regular unsweetened cocoa powder, not Dutch processed, for best results.
  2. Zucchini from a medium-sized vegetable is preferred over large ones, which may contain too much water.
  3. Do not overmix the batter as it may result in a dense texture.
  4. For the best texture and flavor, allow the bread to cool completely before slicing.
  5. The baking time may vary depending on your oven and the type of pan used. A standard metal pan is recommended.
