Three Loaves in One Recipe

Coat three 5-3/4-in. x 3-in. x 2-in. loaf pans with cooking spray; set aside. In a small bowl, combine the flour, sugar, baking powder, salt and baking soda. Whisk the egg, orange juice and butter; stir into dry ingredients just until moistened. Transfer 3/4 cup batter to another bowl; stir in the zucchini, orange peel and cinnamon. Pour into one prepared pan. Transfer 3/4 cup batter to a second bowl. Toss blueberries with flour; fold into batter. Pour into second pan. Combine honey and orange juice; set aside. Stir sour cream into remaining batter; spoon half of the batter into third pan. Combine sugar and cinnamon; sprinkle over batter. Top with remaining batter; cut through with a knife to swirl. Bake all three loaves at 325 ° for 33-36 minutes or until a toothpick inserted near the center comes out clean. Pour reserved honey mixture over warm blueberry bread. Cool loaves for 10 minutes before removing from pans to a wire rack. Whisk confectioners' sugar and milk until smooth; drizzle over cooled cinnamon bread.
