Made 4 loaves for church this year because I got so many compliments last year

1. Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan.
2. In a medium bowl, whisk together the flour, cinnamon, baking soda, baking powder, and salt.
3. In a large bowl, beat the egg lightly, then add the oil, granulated sugar, brown sugar, and vanilla extract. Mix until well combined.
4. Stir the grated zucchini and apple into the wet mixture.
5. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix.
6. Fold in the chopped nuts if using.
7. Pour the batter into the prepared loaf pan and smooth the top.
8. Bake in the preheated oven for 55-60 minutes, or until a toothpick inserted into the center comes out clean.
9. Let the bread cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely before slicing.
