Spelt flour, zucchini, applesauce, and chocolate chips may seem like a crazy combination, but you're going to love them together in this moist and delicious update on the classic zucchini bread.
Preheat oven to 350 degrees. Coat four 3-by-5 1/2-inch loaf pans with cooking spray. Line each with parchment, leaving 2 inches of overhang on long sides. Spray parchment.
Whisk together flours, baking powder, salt, and cinnamon in a bowl. In another bowl, whisk together eggs, oil, applesauce, sugar, zucchini, and vanilla. Stir in flour mixture until combined. Stir in chocolate.
Divide batter evenly among prepared pans, filling each three-quarters full (about 1 1/2 cups a pan). Bake until a tester inserted in centers comes out clean, about 45 minutes. Let loaves cool completely on wire racks before removing from pans. Loaves can be stored at room temperature up to 2 days.
You can also bake all the batter in one large, 5-by-10-inch loaf pan for 1 hour, 5 minutes.
