Ingredients
  

Vegetables
  • 2 cups shredded zucchini (about 200 grams)
Baking Essentials
  • 1 ¾ cups all-purpose flour (220 grams)
  • ¾ cup unsweetened cocoa powder (75 grams)
  • 1 tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt
Sweeteners
  • 1 cup sugar (½ cup granulated white sugar and ½ cup brown sugar, 200 grams total)
Liquids
  • ½ cup vegetable oil (120 ml)
Eggs
  • 2 large eggs room temperature
Flavoring
  • 1 tsp vanilla extract
Mix-Ins
  • 1 cup chocolate chunks or chips (170 grams)

Method
 

Preparation
  1. Wash and shred 2 cups of zucchini. Squeeze out excess water using a clean kitchen towel to prevent sogginess.
Mixing Ingredients
  1. In a large mixing bowl, whisk together the flour, cocoa powder, baking soda, baking powder, salt, and sugars until evenly combined.
  2. Add vegetable oil, eggs, and vanilla extract to the dry ingredients. Stir gently with a wooden spoon or silicone spatula until just combined; batter will be thick.
  3. Carefully fold in the shredded zucchini and chocolate chunks or chips to avoid overmixing.
Baking
  1. Pour the batter into a greased 9×5 inch loaf pan and smooth the top.
  2. Bake at 350°F (175°C) for 50-60 minutes. Check doneness with a toothpick at 50 minutes; it should come out with moist crumbs but no wet batter.
Cooling
  1. Cool the bread in the pan for 15 minutes, then transfer to a cooling rack for at least 30 minutes before slicing.

Notes

Ensure not to overmix the batter after adding zucchini and chocolate to maintain a moist texture. Store wrapped at room temperature for up to 3 days or freeze for longer storage. Consider using whole wheat flour or reducing sugar for a healthier option.
