How to Make Double Chocolate Zucchini Bread Recipe

Step 1: Prep and Mix Your Dry Ingredients

First, preheat your oven to 350°F (177°C) and grease your loaf pan—9×5 inches works great, but an 8×4 inch gives a taller loaf if you prefer. In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and espresso powder until fully combined. Then stir in the chocolate chips so they’re evenly distributed and won’t sink to the bottom while baking.

Step 2: Whisk Wet Ingredients Separately

In a separate bowl, beat the eggs with the oil, Greek yogurt, sugar, and vanilla extract until smooth. This helps ensure your batter comes together easily without overmixing the flour later, which can make bread tough.

Step 3: Combine Wet and Dry, Then Fold in Zucchini

Pour the wet mixture into the bowl of dry ingredients, stirring gently just until combined. The batter will be thick, which is absolutely right. Now fold in the shredded zucchini evenly. Resist the urge to overmix here; it’s key to keeping the bread tender.

Step 4: Bake Carefully for Moist Perfection

Pour the batter into your prepared pan and place in the oven for 45 to 55 minutes. Around the halfway mark, loosely cover the top with aluminum foil to prevent over-browning. Start checking at 45 minutes by inserting a toothpick; it should come out with just a few moist crumbs but no raw batter. The exact timing depends on your oven and pan size, so keep an eye on it!

Step 5: Cool and Optional Chocolate Chip Finish

Once baked, let the bread cool in the pan on a wire rack for about an hour. While still warm, I like to press a few extra chocolate chips on top for a prettier finish—totally optional but adds a lovely touch. Then remove the bread from the pan and cool completely.

Pro Tips for Making Double Chocolate Zucchini Bread Recipe

  • Don’t Overmix: I learned the hard way that over-stirring makes the bread dense, so mix until just combined.
  • Use Natural Cocoa Powder: It really heightens the chocolate flavor compared to Dutch-process and makes baking soda work properly.
  • No Need to Peel Zucchini: Leaving the skin adds color and nutrients, plus it gets tender when baked.
  • Cover Mid-Bake: Preventing over-browning with foil halfway ensures the top doesn’t get too dark before the middle is done.

How to Serve Double Chocolate Zucchini Bread Recipe

Two slices have been taken from the loaf and placed beside it, revealing a moist crumb filled with chocolate chips that are melted and shiny. The top of the loaf is slightly cracked and studded with more chocolate chips, giving it a rich, textured look. A green cloth with a soft texture is casually draped in the background.

Garnishes

I sometimes sprinkle extra chocolate chips or a light dusting of powdered sugar just before serving, which adds a pretty, homemade look. A swipe of softened butter or cream cheese spread really brings out the richness, especially if you’re serving it as breakfast or a snack.

Side Dishes

I love pairing this bread with fresh fruit or a simple cup of coffee or tea. For a brunch spread, it goes wonderfully alongside scrambled eggs or a cheesy frittata—balance out the sweetness with something savory.

Creative Ways to Present

For a party, I’ve sliced this bread into thick pieces and arranged them on a platter with fresh berries and mint leaves. You can also turn it into muffins or cupcakes by using the same batter, which I find perfect for gifting or lunchboxes.

Make Ahead and Storage

Storing Leftovers

After it cools completely, I keep my Double Chocolate Zucchini Bread wrapped tightly in plastic wrap or an airtight container at room temperature. It stays perfectly moist and fresh for about 5 days, making it a great make-ahead option.

Freezing

I’ve frozen sliced loaves without issue—just wrap individual slices or the whole loaf very tightly in plastic wrap and then foil or a freezer bag. It keeps well up to 3 months. When I want to enjoy it, I thaw in the fridge overnight, and it tastes almost as fresh as the day I baked it.

Reheating

To warm up leftovers, I pop a slice into the microwave for about 20 seconds or toast it lightly for a lovely slightly crispy edge. If it’s a whole loaf, warming in a low oven (around 325°F) for 10-15 minutes restores that just-baked feel nicely.

FAQs

  1. Can I use frozen zucchini for this Double Chocolate Zucchini Bread Recipe?

    Yes! If you use frozen zucchini, be sure to thaw it fully and lightly blot away excess moisture with a paper towel. This prevents the bread from becoming too wet and helps maintain the perfect texture.

  2. What’s the purpose of espresso powder in this recipe?

    Espresso powder enhances the chocolate flavor, making it richer and deeper without adding a coffee taste. It’s a little trick I discovered that really boosts the overall deliciousness of the bread.

  3. Can I make this Double Chocolate Zucchini Bread Recipe gluten-free?

    Absolutely, you can substitute the all-purpose flour with a gluten-free baking blend that’s meant for one-to-one substitution. Just check that it contains xanthan gum for structure, and your bread should turn out great.

  4. How do I know when the bread is done baking?

    Insert a toothpick in the center—the bread is done when it comes out clean or with just a few moist crumbs attached, but no raw batter. Also, the top should spring back lightly when pressed.

  5. Can I double the recipe for two loaves?

    Yes! Double all ingredients and divide the batter evenly between two loaf pans. If the batter feels too thick, a splash of milk can help adjust the consistency before baking.

Final Thoughts

This Double Chocolate Zucchini Bread Recipe has become one of my absolute favorites to bake and share. It’s a perfect way to sneak in some veggies while satisfying that chocolate craving, with a texture and flavor that impress everyone. I truly hope you enjoy making it as much as I do—once you try it, I’m betting this will become a staple in your baking repertoire just like it is in mine!

Ingredients

Units Scale

Dry Ingredients

  • 1 cup (125g) all-purpose flour (spooned & leveled)
  • 1/2 cup (41g) unsweetened natural cocoa powder (not Dutch process)
  • 3/4 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1/2 teaspoon espresso powder
  • 3/4 cup (135g) semi-sweet chocolate chips

Wet Ingredients

  • 2 large eggs
  • 1/4 cup (60ml) vegetable oil or melted coconut oil
  • 1/3 cup (80g) plain Greek yogurt or sour cream
  • 2/3 cup (135g) granulated sugar
  • 1 teaspoon pure vanilla extract
  • 1 and 1/2 cups (180g) shredded zucchini (no need to blot)

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (177°C). Grease a 9×5-inch or 8×4-inch loaf pan with nonstick spray and set aside.
  2. Mix dry ingredients: In a large bowl, whisk together the all-purpose flour, natural cocoa powder, baking soda, baking powder, salt, and espresso powder until well combined. Stir in the semi-sweet chocolate chips. Set the mixture aside.
  3. Mix wet ingredients: In a medium bowl, whisk the eggs, vegetable oil (or melted coconut oil), plain Greek yogurt (or sour cream), granulated sugar, and vanilla extract until combined.
  4. Combine wet and dry ingredients: Slowly pour the wet ingredients into the dry ingredients and gently whisk or fold until just combined. Fold in the shredded zucchini carefully. The batter will be thick.
  5. Bake the bread: Pour the batter into your prepared loaf pan. Bake for 45 to 55 minutes. About halfway through baking, loosely cover the bread with aluminum foil to prevent the top from over-browning. The 9×5-inch pan will be closer to 45 minutes, and the 8×4-inch pan will take closer to 55 minutes. Begin checking doneness at around 45 minutes by inserting a toothpick into the center; it should come out clean or with a few moist crumbs.
  6. Cool the bread: Remove the bread from the oven and let it cool in the pan on a wire rack for 1 hour. Optionally, while still warm, press a few extra chocolate chips on top for an attractive finish.
  7. Finish cooling and store: Remove the bread from the pan and cool completely on the wire rack. Store covered at room temperature for up to 5 days or refrigerate for up to 1 week.
