• Step 1: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or non-stick cooking spray.
• Step 2: In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, and salt until well combined.
• Step 3: In a separate bowl, beat the eggs, then stir in the vegetable oil and vanilla extract.
• Step 4: Pour the wet ingredients into the dry ingredients and stir just until combined, being careful not to overmix. Fold in the shredded zucchini.
• Step 5: Pour the batter into the prepared baking pan and spread it out evenly.
• Step 6: Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
• Step 7: Allow the cake to cool completely in the pan before cutting and serving.
