Perfect for breakfast, brunch, snack time, or dessert, this bread is easy to bake and freezes well for future enjoyment.

Why Sour Cream Makes a Difference

Sour cream adds richness and moisture to quick breads, keeping the crumb soft and tender even days after baking. Combined with shredded zucchini, it produces a loaf that’s ultra-moist and flavorful without being greasy.

Ingredients

2 cups all-purpose flour
½ cup unsweetened cocoa powder
1 teaspoon baking soda
½ teaspoon baking powder
½ teaspoon salt
1 teaspoon ground cinnamon
½ teaspoon ground nutmeg
1 cup brown sugar, packed
2 large eggs
½ cup vegetable oil
½ cup sour cream
1 teaspoon vanilla extract
1½ cups shredded zucchini (about 1 medium zucchini)
½ cup chocolate chips (optional)

Instructions

Preheat oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan.
In a medium bowl, whisk together flour, cocoa powder, baking soda, baking powder, salt, cinnamon, and nutmeg.
In a large bowl, beat brown sugar, eggs, oil, sour cream, and vanilla until smooth.
Fold shredded zucchini into the wet mixture.
Gradually mix in dry ingredients until just combined. Do not overmix.
Fold in chocolate chips if using.
Pour batter into prepared loaf pan and smooth the top.
Bake 50–60 minutes, or until a toothpick inserted into the center comes out clean.
Allow bread to cool in the pan for 10 minutes, then remove to a wire rack to cool completely before slicing.

Flavor and Texture

This bread is rich, chocolatey, and ultra-moist with tender crumbs. The zucchini melts into the batter, adding moisture without altering the chocolate flavor. Sour cream enhances the softness, while chocolate chips add melty pockets of chocolate in every bite.
