Get your oven hot: First, set your oven to 350°F (175°C) and grease your 8.5 x 4.5 inch loaf pan so the bread won’t stick later on.
Combine Dry Ingredients: In a big bowl, whisk together 1 ½ cups of all-purpose flour, ½ cup of cocoa powder, 1 tsp of baking soda, ½ tsp of baking powder, salt, and cinnamon.
Mix the wet Ingredients: In another bowl, beat the 2 large eggs with the ½ cup of vegetable oil, ½ cup of granulated sugar, ½ cup of brown sugar, and 2 tsp of vanilla.
Prepare the Zucchini: Grate 2 cups of zucchini and use a clean towel to squeeze out all the extra water until it’s nice and dry.
Put it all together: Pour the wet mix into the dry mix and stir gently. Then, fold in your squeezed zucchini and 1 cup of chocolate chips.
Time to bake: Pour the batter into your pan and bake it for 50-60 minutes. You can check if it’s done by poking it with a toothpick.
Let it cool down: Let your loaf cool in the pan for about 10 minutes before you move it to a wire rack to cool all the way.
