Triple Chocolate Zucchini Bread Recipe: Fudgy Loaf

This rich, moist chocolate zucchini bread melts in your mouth and tastes like your favorite chocolate cake.

I had a few zucchini sitting in the refrigerator and decided to turn them into something irresistible. If you’ve ever planted zucchini, you know how quickly a few plants can produce more than you expect—so finding simple, delicious ways to use them is a must. This chocolate zucchini bread is a perfect example: it uses fresh shredded zucchini for moisture and texture while delivering deep chocolate flavor.

The recipe layers chocolate in several ways: unsweetened cocoa powder in the batter, mini semi-sweet chips for pockets of melted chocolate throughout, and white chocolate chips on top for a pretty, contrasting finish. A pinch of instant coffee deepens the chocolate notes without imparting a coffee taste, and a touch of Greek yogurt keeps the crumb tender. The result is a loaf that feels more like a chocolate cake than a traditional quick bread—dense, rich, and satisfying.

Ingredients you’ll need:

• 1 1/2 cups shredded zucchini
• 1 cup all-purpose flour
• 1/2 cup unsweetened cocoa powder
• 3/4 teaspoon baking soda
• 1/4 teaspoon baking powder
• 1/4 teaspoon salt
• 1/2 teaspoon instant coffee powder
• 3/4 cup mini semi-sweet chocolate chips
• 2 large eggs
• 1/4 cup vegetable oil
• 1/4 cup Greek yogurt
• 3/4 cup granulated sugar
• 1 teaspoon vanilla extract
• 1/4 cup white chocolate chips (for topping)

Step-by-Step Instructions:

1. Preheat the oven to 350°F (175°C). Grease an 8 x 4-inch loaf pan or line it with parchment paper.
2. Shred the zucchini using the large side of a box grater. Place the shredded zucchini on folded paper towels and gently press to absorb some excess moisture.
3. In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, instant coffee powder, and the mini semi-sweet chocolate chips.
4. In a separate medium bowl, whisk the eggs, vegetable oil, Greek yogurt, sugar, and vanilla until combined.
5. Add the wet ingredients to the dry ingredients and stir just until combined; do not overmix.
6. Fold in the shredded zucchini until evenly distributed throughout the batter.
7. Transfer the batter to the prepared loaf pan and smooth the top with a spatula.
8. Bake at 350°F for 45–55 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs attached. Ovens vary, so check at 45 minutes.
9. Remove the loaf from the oven and immediately sprinkle the white chocolate chips over the top so they adhere without completely melting.
10. Allow the bread to cool in the pan on a wire rack for about 10 minutes, then remove it from the pan and let it cool further on the rack before slicing.

Tips and Variations

• Drain the zucchini lightly: You want some moisture for a tender crumb, but too much liquid can make the loaf dense. Blotting with paper towels helps strike the right balance.
• Swap-ins: For a slightly lighter loaf, replace half the oil with unsweetened applesauce. For a deeper chocolate profile, use bittersweet or dark chocolate chips in place of the semi-sweet.
• White chocolate topping: Adding the white chips immediately after baking gives a pretty finish while leaving some chips intact on the surface instead of fully melting in.
• Parchment alternatives: If you don’t have parchment paper, grease the pan well with butter or nonstick spray. Avoid wax paper in the oven.

Storage and Freezing

This zucchini bread stores well at room temperature for 2–3 days wrapped in foil or stored in an airtight container. For longer storage, wrap individual slices or the whole loaf tightly in plastic wrap and place in a freezer bag or sealed container. Properly wrapped, the bread can be frozen for up to 3 months. Thaw in the refrigerator or at room temperature, and warm slices briefly in the microwave or oven before serving if you prefer them warm.

Frequently Asked Questions

Will the white chocolate melt if I add it before baking? Yes—white chocolate will usually melt if added prior to baking. For a decorative top with visible chips, add the white chocolate immediately after the loaf comes out of the oven.

Can I make muffins instead? Yes. Scoop the batter into a lined or greased muffin tin and bake at 350°F for about 16–20 minutes, or until a toothpick comes out clean. Baking time will be shorter since muffins are smaller than a loaf.
