It’s easy to make, rich in flavor, and even better the next day. A favorite among home bakers, Triple Chocolate Zucchini Bread is a delightful balance between comfort food and nutrient-rich baking that satisfies the sweet tooth without the guilt.
The History of Chocolate Zucchini Bread
Zucchini bread rose in popularity during the 1960s and 70s, particularly in North America, when home gardening became more widespread and people looked for creative ways to use abundant summer zucchini. Quick breads—those made without yeast—became a canvas for experimenting with fruits and vegetables, and zucchini proved to be an ideal choice due to its high water content and neutral flavor. As chocolate became a more common baking ingredient, bakers discovered that combining it with zucchini not only masked the vegetable’s taste but also resulted in an exceptionally moist and tender crumb. The addition of chocolate chips and melted chocolate later evolved to satisfy cravings for more intense dessert-like versions. Today, chocolate zucchini bread is a staple in many households, valued for being both wholesome and decadent, with “triple chocolate” variations earning cult status among chocolate lovers.
Ingredients Breakdown
All-Purpose Flour: Forms the structural base of the loaf, keeping it light yet sturdy enough to hold moisture from the zucchini.
Unsweetened Cocoa Powder: Provides the foundational chocolate flavor and dark color.
Baking Soda and Baking Powder: Leavening agents that help the bread rise while maintaining a tender texture.
Salt: Enhances the chocolate flavor and balances sweetness.
Granulated Sugar and Brown Sugar: Granulated sugar sweetens the bread, while brown sugar adds moisture and a slight molasses depth.
Eggs: Bind the ingredients and contribute to the structure and moisture.
Oil (vegetable or coconut): Keeps the bread incredibly moist and helps create a tender crumb.
Vanilla Extract: Adds warmth and depth, enhancing the chocolate flavor.
Shredded Zucchini: Adds moisture, nutrients, and subtle texture while remaining undetectable in flavor.
Chocolate Chips: Folded into the batter and optionally sprinkled on top for melty pockets of chocolate throughout.
Melted Chocolate: Intensifies the chocolate experience and contributes to the rich, fudgy consistency.
Step-by-Step Recipe
- Preheat the oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper for easy removal.
- Prepare the zucchini by washing and shredding it with a box grater. Measure out 1½ to 2 cups (about 250g) and gently blot with a paper towel—do not squeeze dry completely, as the moisture is essential for the texture.
- Mix dry ingredients: In a large bowl, whisk together 1½ cups all-purpose flour, ½ cup unsweetened cocoa powder, 1 teaspoon baking soda, ½ teaspoon baking powder, and ½ teaspoon salt.
- Combine wet ingredients: In another large bowl, whisk ½ cup vegetable oil with ¾ cup granulated sugar, ¼ cup brown sugar, 2 large eggs, and 1 teaspoon vanilla extract until smooth.
- Add zucchini: Stir the shredded zucchini into the wet ingredients.
- Melt chocolate: In a heatproof bowl, melt ½ cup chopped dark chocolate or chocolate chips in the microwave in short intervals, stirring until smooth, then mix it into the wet ingredients.
- Combine: Gradually fold the dry ingredients into the wet ingredients using a spatula until just combined—do not overmix.
- Fold in chocolate chips: Stir in ½ to ¾ cup chocolate chips (semisweet or dark).
- Bake: Pour the batter into the prepared loaf pan and top with extra chocolate chips if desired. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out with moist crumbs but no raw batter.
- Cool and serve: Let the bread cool in the pan for 10–15 minutes, then transfer to a wire rack to cool completely. Slice and enjoy slightly warm or at room temperature.
Tips for the Perfect Triple Chocolate Zucchini Bread
Use fresh zucchini with the skin on and no need to peel—it melts into the bread while baking. Don’t wring out the zucchini completely; you want it to retain some of its natural moisture. Use high-quality cocoa powder and chocolate chips for a richer flavor. Mix the batter gently to avoid overdeveloping the gluten, which can lead to a dense loaf. Test for doneness by checking a few spots in the center with a toothpick—chocolate chips can make it tricky. For an extra decadent loaf, swirl a few spoonfuls of melted chocolate or chocolate-hazelnut spread into the top before baking. Let the bread cool fully before slicing to help it set and hold together.
Variations and Customizations
Add chopped walnuts, pecans, or hazelnuts for crunch and texture. Replace half the all-purpose flour with whole wheat flour for added fiber and a nutty flavor. Use dark chocolate chunks instead of chips for pools of melted chocolate throughout the loaf. Add a teaspoon of espresso powder to enhance the chocolate flavor. For a vegan version, substitute eggs with flax eggs (1 tbsp ground flaxseed + 2.5 tbsp water per egg) and use dairy-free chocolate and oil. Incorporate a swirl of peanut butter or almond butter for a nutty twist. For a lighter glaze, drizzle the cooled loaf with a mixture of powdered sugar, cocoa powder, and almond milk.
Health Considerations and Nutritional Value
Though rich and dessert-like, Triple Chocolate Zucchini Bread offers some nutritional benefits thanks to its inclusion of zucchini, which provides vitamin C, potassium, and fiber. The use of vegetable oil instead of butter helps reduce saturated fat, while cocoa powder adds antioxidants known as flavonoids. You can make it healthier by reducing the sugar slightly, using whole wheat flour for added fiber, or incorporating applesauce in place of some oil. One slice typically contains 250–350 calories depending on portion size and add-ins, making it a reasonable indulgence when balanced with other meals. Despite its dessert status, it’s a smarter choice than many store-bought baked goods due to the control over ingredients and the addition of vegetables.
FAQ
Can I taste the zucchini? No—the zucchini is flavorless and blends into the chocolate, contributing moisture without altering taste.
Can I use frozen zucchini? Yes, but be sure to thaw and blot excess liquid. Frozen zucchini tends to be wetter and may affect texture.
How do I store this bread? Keep it wrapped in plastic or an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
Can I freeze it? Absolutely—wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge or at room temperature before serving.
Can I use Dutch-process cocoa? Yes, but if you do, make sure your leavening agents are balanced, as Dutch-process cocoa is less acidic.
Why is my bread too moist or gummy? Overmixing, excess liquid from zucchini, or underbaking can lead to a gummy texture. Use a scale to measure ingredients accurately and test for doneness.
Triple Chocolate Zucchini Bread
Ingredients
- 1 cup 125g all-purpose flour, spooned and leveled
- ½ cup 41g unsweetened natural cocoa powder (not Dutch-process)*
- ¾ teaspoon baking soda
- ¼ teaspoon baking powder
- ¼ teaspoon salt
- ½ teaspoon espresso powder*
- ¾ cup 135g semi-sweet chocolate chips*
- 2 large eggs
- ¼ cup 60ml vegetable oil or melted coconut oil
- ⅓ cup 80g plain Greek yogurt or sour cream*
- ⅔ cup 135g granulated sugar*
- 1 teaspoon pure vanilla extract
- 1½ cups 180g shredded zucchini (no need to blot)*
Instructions
- Preheat your oven to 350°F (177°C). Grease a 9×5-inch loaf pan or an 8×4-inch loaf pan (for a taller loaf) with nonstick spray and set aside. In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and espresso powder until well combined. Stir in the chocolate chips and set the mixture aside. In a medium bowl, whisk the eggs, oil, yogurt, granulated sugar, and vanilla extract until smooth. Gradually add the wet ingredients to the dry ingredients, gently whisking to combine. Fold in the shredded zucchini; the batter will be thick. Pour the batter into the prepared pan and bake for 45–55 minutes, loosely covering the bread with aluminum foil halfway through baking to prevent the top from over-browning. The 9×5-inch pan usually needs about 45 minutes, while the 8×4-inch pan takes closer to 55 minutes. Since ovens vary, start checking doneness at around 45 minutes by inserting a toothpick into the center—it should come out clean with just a few moist crumbs. Remove the bread from the oven and let it cool in the pan on a wire rack for 1 hour. While still warm, you can gently press a few extra chocolate chips onto the top for decoration if desired. Then, remove the bread from the pan and place it directly on the wire rack to cool completely. Store the bread covered at room temperature for up to 5 days or refrigerate for up to 1 week.
