Preheat the oven to 350°F. Spray 2 8x4-inch loaf pans with cooking spray and line with parchment paper. Set aside.
In a large bowl, mix together zucchini, applesauce, eggs, vanilla, and sugar.
In a separate bowl, mix together flours, cinnamon, cardamom baking soda, salt, and baking powder. Add to wet ingredients and stir until just blended.
Pour batter into pans and bake 50-60 minutes, until a toothpick inserted into the center comes out clean. Let loaves cool in the pans 10 minutes, then remove from pans and let cool completely on a rack.
Notes
Makes 2 loaves.
Swap in up to half of the flour with white whole wheat flour.
