Step 1: Preheat the Oven. Start by preheating your oven to 350°F (175°C) to ensure even baking.
Step 2: Prepare Your Loaf Pan. Grease your loaf pan with non-stick spray or line it with parchment paper.
Step 3: Mix Dry Ingredients. In a large mixing bowl, whisk together flour, cocoa powder, baking powder, baking soda, sea salt, cinnamon, and nutmeg until well combined.
Step 4: Combine Wet Ingredients. In another bowl, beat the eggs, then add vegetable oil, granulated sugar, and vanilla extract. Whisk until smooth.
Step 5: Combine Mixtures. Pour the wet mixture into the dry ingredients and stir until just combined.
Step 6: Add Zucchini and Chocolate Chips. Fold in shredded zucchini and semisweet chocolate chips using a spatula.
Step 7: Pour into Loaf Pan. Transfer the batter to your prepared loaf pan and smooth the top.
Step 8: Bake. Place the loaf pan in the preheated oven and bake for 50-60 minutes, or until a toothpick comes out clean.
Step 9: Cool and Serve. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
