Lightly spray a 4x8-inch loaf pan with non-stick spray. Set aside.
In a large bowl, combine dry ingredients: both flours, baking powder, baking soda, and salt. Mix well.
In a smaller bowl, combine remaining wet bread ingredients (egg whites, sugar, oil, cherry preserves, juice, vanilla extract, and almond extract). Beat with a fork or whisk until well combined. Add wet ingredients to dry ingredients, mixing until all ingredients are moistened. Pour into prepared pan.
Bake 30-35 minutes, or until a wooden toothpick inserted in the center of the bread comes out clean.
Cool in pan 5 minutes, then transfer to a rack to finish cooling.
Make dark chocolate icing:
Mix powdered sugar, milk, and cocoa together until smooth.
With the bread still on the cooling rack, drizzle the glaze over the cooled bread, or pour over the top, using as much or as little as you like.
