In a large bowl whisk together the flour, sugars, orange zest, baking powder, salt and baking soda. Add the melted butter, sour cream, buttermilk, orange juice, vanilla extract and eggs mixing well with a spoon. Fold in the cranberries and nuts. Spray two 8 x 5 loaf pans with cooking spray or one 9 x 5 and bake in preheated 350 degree oven 40 to 45 minutes. (I like to make two smaller loaves because I give one of them away or you can make the one larger loaf)
TOPPING INSTRUCTIONS:
Whisk together and drizzle over bread. Can add more sugar or more milk to get the consistency you like.
