Prep Your Pans: Preheat your oven to 350°F (175°C). Grease 3-4 standard loaf pans and line 24 muffin cups, or grease them very well.
Grate the Zucchini: Wash your zucchini and trim the ends. Grate it using a food processor with the shredding disc (the fastest way!) or the large holes of a box grater.
Mix Wet Ingredients: In a very large bowl, whisk together the sugar (or honey), eggs, oil, and vanilla until smooth and well combined.
Add Zucchini: Stir the 7 cups of grated zucchini into the wet ingredients.
Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Combine: Add the dry ingredients to the wet ingredients in a few batches, stirring gently with a spatula just until no dry streaks of flour remain. Be careful not to overmix, as this can make the bread tough.
Fold in Extras: Gently fold in any optional add-ins like nuts or chocolate chips.
Fill Pans: Fill your prepared loaf pans about ⅔ full and the muffin cups about ¾ full. An ice cream scoop works perfectly for portioning muffin batter evenly.
