This decadent chocolate zucchini bread transforms garden vegetables into a dessert-like treat that even veggie-skeptics will devour. The rich chocolate flavor completely masks the zucchini while benefiting from its moisture-adding properties for an irresistibly tender loaf.

I first created this bread during a summer when our garden produced more zucchini than we could possibly eat. My chocolate-loving husband claimed he could detect the vegetables, until I served it to him without mentioning the secret ingredient and he devoured three slices thinking it was just chocolate bread.

Ingredients

  • All purpose flour: provides the perfect structure while keeping the crumb tender
  • Dutch process cocoa: gives a deeper chocolate flavor than regular cocoa but either works beautifully
  • Baking soda: creates the perfect rise when activated by the moisture in zucchini
  • Sea salt: enhances all the flavors especially the chocolate notes
  • Room temperature eggs: blend more evenly into the batter for proper emulsification
  • Melted butter: adds richness that vegetable oil alone cannot provide
  • Oil: keeps the bread moist for days longer than recipes using only butter
  • Brown sugar: provides more moisture and caramel notes than white sugar
  • Pure vanilla extract: balances and enhances the chocolate flavor
  • Shredded zucchini: disappears completely while adding incredible moisture
  • Semisweet chocolate chips: create pockets of melty goodness throughout

Step-by-Step Instructions

Prepare Your Equipment:
Heat your oven to 350°F and thoroughly grease your loaf pan ensuring you get into all corners and crevices to prevent sticking which can ruin a beautiful loaf after baking.
Combine Dry Ingredients:
Whisk together flour cocoa powder baking soda and salt ensuring there are absolutely no cocoa lumps which would create bitter spots in your finished bread.
Mix Wet Ingredients:
In a separate larger bowl combine eggs butter oil vanilla and brown sugar stirring until well incorporated but not worrying about small brown sugar lumps which will dissolve during baking adding caramel notes.
Combine Wet and Dry:
Gently mix the dry ingredients into wet ingredients using a folding motion rather than vigorous stirring which develops gluten and creates a tough bread texture.
Add Zucchini and Chocolate:
Fold in the shredded zucchini which provides essential moisture without needing to be squeezed dry first then incorporate most of the chocolate chips reserving some for the top.
Bake to Perfection:
Pour batter into your prepared pan sprinkle remaining chocolate chips on top and bake for 50 to 60 minutes until a toothpick inserted comes out mostly clean with perhaps a bit of melted chocolate but no wet batter.
Cooling Process:
Allow the bread to cool in the pan for exactly 15 minutes which gives the structure time to set before carefully removing to finish cooling on a wire rack preventing a soggy bottom.

The real secret to this bread is not overmixing once you add the zucchini. I learned this after making countless loaves and noticing that a gentle fold creates a much more tender crumb than vigorous stirring. My family actually requests this bread year-round now I keep grated zucchini in the freezer specifically for winter baking emergencies.

Best Zucchini Preparation

Always use the fine side of your box grater when preparing zucchini for this bread. Larger shreds remain more noticeable in the final product which can alert suspicious vegetable avoiders. No need to peel the zucchini first as the skin contains nutrients and disappears completely in the dark bread. If your zucchini is particularly watery especially large garden specimens you may want to lightly blot but not completely squeeze dry as that moisture is beneficial to the recipe.

Make It Your Own

This versatile recipe welcomes customization based on your preferences. Swap walnuts or pecans for some of the chocolate chips for added texture and nutritional benefits. For a mocha variation add one tablespoon of espresso powder to the dry ingredients which intensifies the chocolate flavor without tasting like coffee. Those avoiding refined sugar can substitute coconut sugar for the brown sugar with minimal texture changes. For a gluten-free version use a 1to1 gluten-free flour blend but add an extra egg to help with binding.

Serving Suggestions

While delicious on its own this chocolate zucchini bread reaches new heights when served slightly warm with a spread of salted butter or cream cheese. For an indulgent dessert toast a slice and top with a scoop of vanilla ice cream and a drizzle of caramel sauce. Cut into small cubes this bread makes an unexpected addition to a brunch buffet or dessert platter. Children especially love it in lunch boxes where it feels like a special treat while secretly containing vegetables.

Common Queries

→ Why add zucchini to chocolate bread?

Zucchini helps keep the loaf moist and tender without making it taste like vegetables. It also blends seamlessly into the chocolate flavor and adds a soft texture.

→ Can I use regular cocoa instead of Dutch process?

Yes, either unsweetened cocoa or Dutch process works. Dutch process will give a deeper chocolate flavor and color, but both are delicious.

→ Do I need to peel the zucchini?

No need to peel! Simply wash and shred the zucchini. The skin is tender and nearly disappears in the loaf.

→ What's the best way to store this bread?

Wrap the loaf tightly in plastic wrap and keep at room temperature for up to four days. You can also freeze slices for longer storage.

→ How do I prevent sogginess in the loaf?

Make sure to squeeze out excess moisture from the shredded zucchini before adding it to the batter. This helps the loaf bake evenly.

What You’ll Need

→ Dry Ingredients

01 1 cup all-purpose flour
02 1/2 cup Dutch process cocoa or unsweetened cocoa
03 1 teaspoon baking soda
04 1/2 teaspoon sea salt

→ Wet Ingredients

05 2 large eggs, at room temperature
06 1/4 cup unsalted butter, melted and slightly cooled
07 1/4 cup canola oil, vegetable oil, or melted coconut oil
08 3/4 cup packed light brown sugar
09 1 teaspoon pure vanilla extract
10 1 1/2 cups packed shredded zucchini

→ Add-ins

11 1 cup semisweet chocolate chips, divided

Steps to Follow

Step 01

Preheat your oven to 350°F (175°C). Grease a 9-by-5-inch loaf pan with nonstick cooking spray and set aside.

Step 02

In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and sea salt. Set aside.

Step 03

In a large bowl, combine the eggs, melted butter, oil, brown sugar, and vanilla extract. Stir until smooth, leaving small brown sugar clumps if necessary.

Step 04

Stir the dry ingredients into the wet ingredients, being careful not to overmix. Gently fold in the shredded zucchini and 3/4 cup of the chocolate chips until just combined.

Step 05

Pour the batter into the prepared loaf pan. Sprinkle the remaining 1/4 cup of chocolate chips evenly over the top.

Step 06

Bake for 50-60 minutes or until a toothpick inserted into the center comes out mostly clean (melted chocolate chips on the toothpick are fine, but there should not be gooey batter).

Step 07

Remove the pan from the oven and set on a wire cooling rack. Let the bread cool in the pan for 15 minutes. Run a knife around the edges and carefully remove the bread from the pan. Allow the loaf to cool until slightly warm before slicing and serving.

Additional Notes

  1. If using coconut oil, ensure it is melted and slightly cooled before incorporating. The bread can be stored on the counter, wrapped in plastic wrap, for up to 4 days. It also freezes well; to freeze, fully cool the bread, wrap it in plastic wrap and aluminum foil, and freeze for up to 1 month. Defrost completely before slicing.
