1. Preheat the oven to 180 C. Spray an 8x4" loaf pan and set aside. 
2. Using a handheld shredder or the shredding attachment of your food processor, shred 1 medium zucchini. Strain out any excess liquid from zucchini and set aside. 
3. In a mixing bowl, whisk together sugars with apple sauce, vegetable oil, and vanilla extract. In a separate bowl combine flour, baking powder, baking soda, salt, and spices. Add dry ingredients to wet and stir to combine. Fold in zucchini and walnuts.
4. Transfer batter into prepared loaf pan and bake for 50-65 minutes until a toothpick inserted in the middle comes out clean. Let cool 10 minutes in the loaf pan before transferring to a wire cooling rack to cool completely.
