1-Preheat your oven to 350°F (175°C) and place a rack in the center position. Prepare a loaf pan by spraying it with baking spray and lining it with parchment paper, leaving some overhang on the sides for easy removal later.

2-Prepare the zucchini by grating it using a box grater or food processor. If the grated zucchini has excess moisture, press it firmly between paper towels or a clean kitchen towel to remove excess liquid. This step is crucial to prevent a soggy texture in your finished bread.

3-In a medium bowl, combine the grated zucchini, brown sugar, granulated sugar, eggs, olive oil, and vanilla. Mix these ingredients thoroughly until well combined and slightly fluffy.

4-In a separate large bowl, whisk together the dry ingredients: all-purpose flour, Dutch process cocoa powder, salt, baking soda, and baking powder. Make sure to distribute the cocoa powder evenly to avoid dark streaks in your bread.

5-Add the zucchini mixture to the dry ingredients and stir until just combined. Be careful not to overmix, as this can result in a tough bread. A few small lumps in the batter are perfectly fine.

6-Fold in most of the chocolate chips, reserving a small handful (about 2 tablespoons) for topping the bread before baking.

7-Pour the batter into the prepared loaf pan and smooth the top with a spatula. Sprinkle the reserved chocolate chips over the top, which will create an attractive, caramelized crust as the bread bakes.

8-Bake for 45 50 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs attached. The exact baking time may vary depending on your oven and the size of your loaf pan.

9-Once baked, let the bread cool in the pan for 5 minutes before transferring it to a wire rack. This resting period helps the bread set and makes it easier to remove from the pan without breaking.

10-Slice the bread with a serrated knife for clean, even cuts. Serve warm or at room temperature, as preferred.
