Preheat your oven to 350°F (175°C) and grease two standard loaf pans with butter or non-stick spray.

In a large mixing bowl, combine granulated sugar, brown sugar, and eggs. Beat until light and fluffy.

In a separate bowl, sift together all-purpose flour, baking soda, salt, cinnamon, and nutmeg.

Gradually add dry ingredients to the wet mixture, folding gently until smooth.

Fold in grated zucchini and diced apples, ensuring even distribution.

Divide the batter evenly between prepared loaf pans and smooth the tops.

Bake for 35 minutes, check for doneness with a toothpick, and cover with foil if needed.

Remove from oven, let cool in pans for 10 minutes before transferring to a wire rack.
