Step 1: Preheat your oven to 350°F (175°C).
Step 2: Grease the muffin tin or line it with parchment liners.
Step 3: In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and ground cloves (if using).
Step 4: In another bowl, beat the eggs and then add the sugar, oil, and vanilla extract. Mix until well combined.
Step 5: Fold the grated zucchini into the wet mixture.
Step 6: Gently add the wet mixture to the dry ingredients and stir until just combined.
Step 7: Divide the batter evenly among the muffin cups, filling each about two-thirds full.
Step 8: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted comes out clean.
Step 9: Let the muffins cool in the tin for 5 minutes before transferring them to a wire rack.
