- 1 1/2 cups all-purpose flour
- 1 1/2 cups whole wheat flour
- 1/4 cup unsweetened cocoa powder
- 1 tablespoon ground cinnamon
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1 teaspoon salt
- 2 cups brown sugar
- 3 eggs
- 1 cup unsweetened applesauce
- 2 teaspoons vanilla extract
- 2 cups shredded zucchini
- 1 cup cinnamon baking chips
- Preheat oven to 350 degrees F (175 degrees C). Grease 2 9×5-inch loaf pans.
- Mix all-purpose flour, whole wheat flour, cocoa powder, cinnamon, baking soda, baking powder, and salt in a bowl until thoroughly combined. Whisk brown sugar, eggs, applesauce, and vanilla extract in a second large mixing bowl. Stir zucchini into the liquid ingredients and beat in flour mixture until batter is just combined; do not overbeat. Gently mix in cinnamon baking chips. Divide batter evenly between prepared loaf pans.
- Bake in preheated oven until lightly golden brown and a toothpick inserted into the center of a loaf comes out clean, 55 minutes to 1 hour. Cool in pans for 10 minutes before removing loaves to finish cooling on wire racks.
