Preheat your oven to 350°F (175°C). Grease a loaf pan or line with parchment paper.

In one bowl, mix the grated zucchini and apples. In another bowl, whisk together the flour, baking soda, granulated sugar, brown sugar, and cinnamon.

In a separate bowl, beat the eggs. Add vegetable oil and vanilla extract; mix until well combined.

Gradually fold the dry mixture into the wet mixture until just combined. Gently stir in the zucchini and apple mixture.

Pour batter into the prepared loaf pan. Bake for 50-60 minutes or until a toothpick comes out clean.

Let it cool in the pan for about 10 minutes before transferring to a wire rack.
