Preheat the oven to 350°F. Grease a 9×5-inch loaf pan or line with parchment paper.

In a large mixing bowl, whisk together flour, baking soda, baking powder, salt, cinnamon, nutmeg, and cloves.

Add eggs, oil, granulated sugar, brown sugar, and vanilla extract to the dry mixture. Stir until just combined.

Fold in grated carrots, grated apple, and nuts (if using). Do not overmix.

Pour batter into the prepared loaf pan and spread evenly.

Bake for 55–65 minutes or until a toothpick inserted in the center comes out clean.

Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
