Preheat oven to 350 degrees. Spray a 9x5 bread loaf pan with cooking spray.
In a small bowl, mix the chopped cranberries, ½ cup of the white sugar and 1 teaspoon of orange zest until the zest is evenly distributed. Set aside.
In a large mixing bowl, whisk (or sift) together the all-purpose flour, remaining sugar, baking powder, baking soda and salt.
In a medium bowl, mash the bananas. Add the eggs and neutral oil and mix until well incorporated.
Pour the banana mixture into the dry ingredients and stir just until combined. Don't over-mix.
Fold in the cranberry mixture and the chopped walnuts until evenly distributed.
Pour the batter into the prepared loaf pan.
Optional topping: In a small bowl, add ¼ cup chopped walnuts, 2 teaspoons of Sugar in the Raw and ½ teaspoon of orange zest. Stir until the orange zest is evenly distributed. Sprinkle evenly over the batter.
Bake for 55 to 60 minutes or until a toothpick inserted in the center comes out clean.
