Double Chocolate Zucchini Bread

Decadent, rich, and irresistibly moist: that’s the promise of double chocolate zucchini bread. This treat blends dark cocoa with bursts of melty chocolate chips and a generous helping of fresh zucchini. The result? A loaf with deep chocolate flavor, a plush crumb, and a whisper of vegetable goodness you can barely detect. Whether you bake it for breakfast, an afternoon treat, or dessert, this chocolate loaf hits the spot every time. Let’s break down how to make it, what to expect, and ways to get creative with your own loaf.

Why Double Chocolate Zucchini Bread Belongs in Your Kitchen

Chocolate bread might sound like dessert, but there’s more at play here. Zucchini sweeps in as the hero ingredient, keeping the loaf extra luscious and tender. You won’t taste the zucchini—its subtlety is its strength. Chocolate shines in two forms: cocoa powder for depth, chocolate chips for pockets of sweetness. The pairing gives this recipe an unbeatable fudgy vibe.

Plus, one bowl, ten minutes of prep, and a standard loaf pan are all you need. The process welcomes both experienced bakers and kitchen beginners. And unlike standard chocolate cakes, this bread sneaks extra nutrition into your snack break—ideal for anyone wanting to eat a bit better without giving up flavor.

The Secrets Behind Stellar Double Chocolate Zucchini Bread

Here’s why this loaf works so well:
Ultra-moist crumb: Zucchini brings much-needed moisture but melts into the batter.
Layered chocolate flavor: Dutch-process cocoa delivers intensity, while chocolate chips offer surprises in every bite.
Just the right texture: Eggs and a touch of sour cream guarantee a soft, sliceable crumb.
Balanced sweetness: Brown sugar adds warmth, white sugar keeps it classic, and vanilla anchors the taste.

You don’t need any electric mixers. A whisk and a spatula will suffice, making cleanup quick.

Ingredients for Double Chocolate Zucchini Bread

A few pantry staples along with fresh zucchini set you up for baking success. Here’s a table to overview the components and their role:

Ingredient Role
Zucchini (shredded, wrung) Moisture, tenderness, and added nutrition
All-purpose flour Structural base for the loaf
Dutch-process cocoa Deep chocolate taste, rich color
Semisweet chocolate chips Bursts of melted chocolate throughout
Brown sugar Subtle caramel notes, extra moisture
White sugar Clean sweetness to balance cocoa
Baking powder + baking soda Lift and fluffiness
Salt Enhances the chocolate and counteracts the sweet
Unsalted butter Fat for tenderness, flavor, and golden edges
Eggs Binding and lightness
Sour cream Added moisture, tanginess, and soft crumb
Vanilla extract Aroma and background flavor
Espresso powder (optional) Accentuates the chocolate, no coffee flavor

Tip: If you prefer, substitute sour cream with plain Greek yogurt for a similar effect.

How to Make Double Chocolate Zucchini Bread: Step-by-Step

1. Prep Your Pan and Oven

Preheat your oven to 350°F (175°C). Grease an 8.5×4.5-inch or standard loaf pan. For easy lifting, line with parchment paper, letting the edges hang over the sides.

2. Prepare the Zucchini

Trim the ends and grate two medium zucchini (about 1½ cups packed). Lay the shreds in a clean towel and squeeze out as much moisture as possible. Extra water can make your loaf soggy. Set aside.

3. Mix the Dry Ingredients

In a medium bowl, whisk:
– 1½ cups all-purpose flour
– ½ cup Dutch-process cocoa powder
– 1 teaspoon baking soda
– ½ teaspoon baking powder
– ½ teaspoon salt
– 1 teaspoon espresso powder (optional)

4. Combine the Wet Ingredients

Melt ½ cup unsalted butter. In a large bowl, whisk the melted butter, ¾ cup packed brown sugar, and ¼ cup white sugar until creamy. Add 2 large eggs, one at a time, whisking after each addition. Stir in ⅓ cup sour cream and 1 teaspoon vanilla.

5. Toss and Fold

Reserve ¼ cup of the dry mix. Sprinkle over the shredded zucchini and toss to coat—this will help keep the zucchini from releasing water as the loaf bakes. Gently fold the remaining dry ingredients into the wet mixture. Add the zucchini and ¾ cup semisweet chocolate chips. Fold until just combined. Don’t overmix; a few streaks are fine.

6. Bake

Pour the thick batter into your prepared loaf pan and spread evenly. Scatter the remaining ¼ cup chocolate chips over the top. Bake for 45–55 minutes. The bread is done when a toothpick comes out with just a few moist crumbs clinging to it.

7. Cool and Slice

Let the bread cool in the pan for 10 minutes. Lift out using parchment, then transfer to a wire rack. Cool completely for clean slices and the fudgiest texture.

Success Tips and Creative Variations

  • Use Dutch-process cocoa for the deepest flavor. Natural cocoa will work but gives a lighter color.
  • If you like crunch, fold in toasted walnuts or pecans.
  • A cream cheese swirl is easy: Mix 4oz cream cheese with 2 tbsp sugar and 1 egg yolk, and swirl into the batter before baking.
  • Don’t skip wringing out the zucchini. Extra water can make the center dense or underdone.
  • Want more chocolate? Add a sprinkle of cocoa nibs to the top for texture.
  • To make muffins: Divide batter among lined muffin tins. Bake at 350°F for 18–22 minutes.

Serving Ideas

Double chocolate zucchini bread is easy to pair. Here are a few ways to enjoy it:
Warm for breakfast with a cup of strong coffee or tea.
As a dessert: Top slices with vanilla ice cream or fresh raspberries.
On the go: Wrap a thick wedge in parchment—ideal for lunch boxes or picnics.
Late-night snack: Zap a slice in the microwave for 10 seconds and enjoy gooey, melty chocolate.

Storing and Freezing

This bread keeps well and even gets more flavorful overnight.

  • At room temperature: Store in an airtight container for up to three days.
  • In the fridge: Wrap tightly and refrigerate for up to seven days. The texture stays moist.
  • In the freezer: Cool completely, then wrap in plastic and foil. Freeze for up to three months. For best results, slice before freezing so you can thaw only what you need.

To reheat: Microwave slices for 10–15 seconds. Or, toast them lightly for a crisp edge and soft center.

Your Double Chocolate Zucchini Bread Questions, Answered

Can I Make This Gluten-Free?

Yes. Swap the all-purpose flour for a gluten-free 1:1 baking blend. I recommend adding an extra ¼ teaspoon xanthan gum.

Does the Loaf Taste Like Zucchini?

Nope. The vegetable melts into the chocolate, offering moisture but no veggie flavor.

Should I Peel the Zucchini First?

Peeling isn’t necessary. The skin is mild and softens during baking.

How Can I Reduce the Sugar?

Cut both sugars by one-third for a less sweet loaf. Keep in mind that texture will be less moist.

Final Thoughts: The Loaf That Wins Over Everyone

Moist, dense, and packed with chocolate, this zucchini bread defies expectations. You’ll find yourself slicing another piece before you know it, whether you’re craving an afternoon treat or a midnight bite. The prep is easy—no stand mixer or fancy equipment required.

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.

  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!
