Preheat your oven to 350°F (175°C).
Prepare a 9x5 inch loaf pan by greasing it or lining it with parchment paper.
In a large mixing bowl, combine the dry ingredients: flour, cocoa powder, baking soda, baking powder, and salt. Mix well.
In another bowl, whisk together the granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract until smooth.
Add the grated zucchini to the wet mixture and stir gently to combine.
Gradually fold the dry ingredients into the wet mixture until just combined. Avoid overmixing.
Carefully fold in the chocolate chips, ensuring an even distribution throughout the batter.
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Once baked, let the bread cool in the pan for 10 minutes before transferring it to a wire rack.
Slice and serve your delicious Double Chocolate Zucchini Bread warm or at room temperature.
