Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that your oven is at the right temperature by the time your batter is ready.
Grease the Loaf Pan: Grease a 9×5-inch loaf pan with cooking spray or butter, ensuring all sides and corners are coated to prevent sticking.
Step 2: Prepare the Dry Ingredients
Combine Dry Ingredients: In a medium bowl, whisk together 1 1/2 cups of all-purpose flour, 1/2 cup of unsweetened cocoa powder, 1 teaspoon of baking soda, 1/2 teaspoon of baking powder, and 1/2 teaspoon of salt. Make sure all the dry ingredients are well combined and any lumps are broken up.
Step 3: Prepare the Wet Ingredients
Mix Wet Ingredients: In a large bowl, mix together 1/2 cup of vegetable oil, 1/2 cup of granulated sugar, 1/2 cup of brown sugar, 2 large eggs, and 1 teaspoon of vanilla extract. Whisk until the mixture is smooth and well combined. The sugars should be fully dissolved into the wet mixture.
Step 4: Combine Wet and Dry Ingredients
Incorporate Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, mixing gently until just combined. Be careful not to overmix; you want to combine them until you no longer see streaks of flour.
Step 5: Add the Zucchini and Chocolate Chips
Fold in Zucchini and Chocolate Chips: Fold in 1 1/2 cups of grated zucchini and 1 cup of chocolate chips into the batter. The zucchini will add moisture to the bread, and the chocolate chips will provide delightful bursts of chocolate in every bite.
