Ingredients and Their Roles

Knowing why each ingredient matters helps you achieve bakery-quality results. Here’s what you’ll need — and why:

Ingredient Purpose
Shredded Zucchini Moisture, subtle earthiness, tender crumb
Dutch-Process Cocoa Powder Deep color and robust chocolate flavor
All-Purpose Flour Framework and structure
Baking Soda & Baking Powder Rise and fluffiness
Salt Balances sweetness, sharpens flavors
Espresso Powder (optional) Intensifies cocoa, no coffee flavor
Unsalted Butter Tender texture, flavor, moist crumb
Granulated Sugar Sweetness, texture
Light Brown Sugar Moisture, hints of caramel
Large Eggs Binding, rise, structure
Sour Cream Tang, moisture, delicate crumb
Vanilla Extract Complexity and warmth
Semisweet Chocolate Chips Melty texture, double chocolate impact

Ingredient Notes

  • Zucchini: Use regular green zucchini. Trim, grate, and don’t bother peeling — the skin melts right into the crumb.
  • Cocoa Powder: Dutch-process offers a mellow, deep flavor, but unsweetened natural cocoa works if that’s what you have.
  • Sour Cream: Full fat is best; you can swap in plain Greek yogurt if needed.
  • Espresso Powder: This is optional, but it makes the chocolate flavor pop.
  • Chocolate Chips: Semisweet balances sweetness, but dark or milk chocolate are fine variations.

Step-by-Step Guide: From Batter to Baked

Let’s break down the process so you get a perfect loaf every time.

1. Set Up for Success

  • Preheat your oven to 350°F (175°C).
  • Grease a standard 9×5-inch loaf pan. Line with parchment for easy removal.

2. Prep the Zucchini

  • Wash and trim the ends.
  • Shred (medium holes on a box grater). For even distribution, avoid large shreds.
  • Place the zucchini in a clean kitchen towel and gently squeeze to remove excess liquid. Aim for damp, not dry.
  • Measure out 1 1/2 cups after draining.

3. Mix Dry Ingredients

  • In a medium bowl, whisk together:
  • 1 3/4 cups all-purpose flour
  • 1/2 cup Dutch-process cocoa powder
  • 1 tsp baking soda
  • 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1 tsp espresso powder (optional)

4. Cream Wet Ingredients

  • In a large bowl, beat together:
  • 1/2 cup unsalted butter, melted and cooled slightly
  • 3/4 cup granulated sugar
  • 1/2 cup light brown sugar

  • Beat until combined and fluffy. Add:

  • 2 large eggs, one at a time, mixing well after each
  • 1/2 cup full-fat sour cream
  • 2 tsp vanilla extract

5. Combine Batter

  • Add the dry ingredients to the wet in three parts, mixing gently after each addition.
  • When just a few streaks of flour remain, fold in:
  • Drained zucchini
  • 3/4 cup semisweet chocolate chips

  • Stir until no dry streaks remain. Don’t overmix.

6. Assemble and Bake

  • Pour batter into your prepared pan.
  • Smooth the top and sprinkle the remaining 1/4 cup chocolate chips over the batter.
  • Bake 50-60 minutes, or until a tester comes out with only a few moist crumbs.

  • If the top darkens too fast, tent with foil in the last 10-15 minutes.

7. Cooling and Slicing

  • Cool in the pan for 10-15 minutes.
  • Lift out using parchment; cool on a rack until completely cooled.
  • Slice gently with a serrated knife for the cleanest pieces.

Tips for Irresistible Double Chocolate Zucchini Bread

Achieve bakery-level results every time with these insights:

  • Don’t overmix: Stir until just combined. Overmixing yields dense bread.
  • Use room temperature eggs and sour cream: This ensures an even, creamy batter.
  • Check for doneness: Ovens vary. Start checking at 50 minutes.
  • Grate, then measure zucchini: Squeeze after grating, then measure for accuracy.
  • Additions: Chopped walnuts, pecans, or dried cherries work beautifully.

Troubleshooting Common Issues

  • Why is my bread gummy? Too much moisture. Squeeze zucchini well and measure carefully.
  • Crumbly texture? Overbaked or too much flour. Spoon flour into your cup, then level off.
  • Chocolate flavor too mild? Use Dutch-process cocoa and include espresso powder for intensity.

Creative Variations

Want to tweak the loaf? Try these spins:

  • Swap half the chocolate chips for peanut butter chips or white chocolate.
  • Add a swirl of cream cheese for a cheesecake-style layer.
  • Mix in toasted hazelnuts for crunch.
  • Stir in orange zest for a burst of citrus against the chocolate.

Serving Suggestions: Breakfast, Snack, Dessert

This bread fits any occasion:

  • Breakfast: Pair with hot coffee or a cold glass of milk.
  • Mid-morning snack: A thick slice keeps you fueled through busy mornings.
  • Satisfying dessert: Warm a slice in the microwave for 15 seconds; the chocolate chips melt into gooey perfection.

For a special touch, serve with a dollop of whipped cream or a small scoop of vanilla ice cream.

Storing and Freezing

Double chocolate zucchini bread stays moist for days, making it perfect for baking ahead.

  • Room Temperature: Keep wrapped airtight up to 3 days.
  • Refrigerator: Store slices in a container for up to a week.
  • Freezer: Wrap slices individually (plastic, then foil), for up to 3 months. Thaw overnight or give a quick zap in the microwave for a speedy treat.

For best texture, avoid storing unwrapped, as this will dry out the crumb.

Frequently Asked Questions

Can I make this gluten-free?

Swap the all-purpose flour for your favorite 1:1 gluten-free blend. Check the texture and add a splash more sour cream if the batter seems too thick.

Can I use another vegetable?

Try finely grated yellow squash or carrots. Both keep the bread moist with minimal flavor change.

How do I keep the bread extra moist?

Sour cream, plenty of zucchini, and not overbaking keep the loaf tender. Avoid reducing the sugar or fat, as these contribute to the texture.

Double chocolate zucchini bread marries the best of two worlds: rich chocolate pleasure and the subtle benefit of veggies. Every bite is soft, moist, and so chocolatey it could pass for cake. Whether you bake for your family, for a weekend brunch, or for a covert way to finish that garden zucchini, this recipe will quickly become your go-to. Pour a cup of coffee, cut a generous slice, and enjoy the taste and texture only this bread delivers.

This easy and indulgent double chocolate zucchini bread is decadently chocolatey. It’s wonderfully moist. It’s perfect for using up summer zucchini.

Ingredients

  • 1/2 cup granulated sugar
  • 1 cup all-purpose flour
  • 1 cup semisweet chocolate chips, divided
  • 2 cups shredded zucchini
  • 1 teaspoon baking soda
  • 2 teaspoons vanilla extract
  • 1/4 cup light brown sugar
  • 2 large eggs, room temperature
  • 1/2 teaspoon espresso powder, optional
  • 1/4 cup sour cream
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1/2 cup Dutch-process cocoa powder
  • 1/3 cup unsalted butter, melted and cooled

Instructions

  1. Preheat the oven to 350°Fahrenheit. Grease a 9x5-inch loaf pan and line with parchment paper, leaving an overhang on the sides.
  2. Grate the zucchini onto a clean kitchen towel, then wring it over the sink to remove excess moisture. Open the towel and spread the zucchini into a thin layer. Pat dry with paper towels and leave to dry until ready to use. (see note)
  3. In a medium bowl, whisk the flour, cocoa powder, baking soda, baking powder, salt, and espresso powder (if using) until well combined. Set aside.
  4. In a separate large bowl, whisk the melted butter, sour cream, and sugars until thick and smooth. Blend in the eggs, one at a time, followed by the vanilla.
  5. Gradually stir about 3/4 of the dry ingredients into the wet ingredients until just combined. Toss the zucchini in the remaining flour until evenly coated. Add to the bowl with 3/4 cup of the chocolate chips. Mix gently just until no streaks of flour are visible.
  6. Pour the batter into the prepared pan and smooth the top. Sprinkle with the remaining 1/4 cup of chocolate chips.
  7. Bake for 45-55 minutes or until a toothpick inserted into the center is removed cleanly or with just a few moist crumbs.
  8. Let the bread cool in the pan for 10 minutes. Then, carefully lift it out using the parchment paper and transfer it to a wire rack to cool completely before slicing. Enjoy!
