# Ingredients:

→ Main Ingredients

01 - 113 g unsalted butter, melted and slightly cooled
02 - 150 g granulated sugar
03 - 1 large egg, plus 1 egg yolk, room temperature
04 - 1 teaspoon vanilla extract
05 - 1/4 cup sour cream, room temperature
06 - 1 3/4 cups shredded zucchini, loosely packed and patted dry
07 - 130 g all-purpose flour
08 - 50 g Dutch process cocoa powder, sifted
09 - 3/4 teaspoon baking powder
10 - 1/2 teaspoon baking soda
11 - 1/4 teaspoon salt
12 - 2/3 cup semi-sweet chocolate chips, plus more for topping

# Instructions:

01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan with non-stick baking spray and line with parchment paper, leaving the edges overhanging for easy removal.
02 - Using a box grater, shred a medium to large zucchini to yield about 1 3/4 cups loosely packed zucchini. Wrap in paper towels or a dishcloth to pat dry and set aside.
03 - In a large bowl, whisk the melted butter and granulated sugar together until pale and well combined.
04 - Mix in the egg followed by the egg yolk until fully incorporated. Add vanilla extract and sour cream; whisk to combine.
05 - Stir in the prepared shredded zucchini until evenly distributed in the mixture.
06 - In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
07 - Add the dry ingredients to the zucchini mixture in two additions. Gently fold using a spatula or wooden spoon. Avoid overmixing.
08 - Gently stir in the semi-sweet chocolate chips until evenly distributed in the batter.
09 - Pour the batter into the prepared loaf pan. Sprinkle additional chocolate chips on top for decoration.
10 - Bake for 45–50 minutes, checking halfway through. If the top is browning too quickly, cover loosely with aluminum foil. Bake until a toothpick inserted into the center comes out clean or with a few crumbs.
11 - Allow the bread to cool in the pan for 20–30 minutes. Use the parchment paper overhangs to lift it out and transfer to a wire rack. Cool completely before slicing, or serve warm.

# Notes:

01 - Patting the shredded zucchini dry helps prevent excess moisture in the batter.
02 - Loosely covering the pan with foil during baking ensures the top doesn’t over-brown.
