Preheat your oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan.
In a medium bowl, whisk together the flour, baking soda, and salt.
In a large bowl, cream together the granulated sugar and softened butter until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with the orange juice, beginning and ending with the dry ingredients. Mix until just combined; do not overmix.
Gently fold in the chopped cranberries and orange zest. If using frozen cranberries, do not thaw them first.
Pour the batter into the prepared loaf pan and spread evenly.
Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
If desired, prepare the orange glaze by whisking together powdered sugar and orange juice until smooth. Drizzle over the cooled bread.
Notes
To prevent cranberries from sinking, toss them with a tablespoon of the flour mixture before folding them into the batter.
This bread freezes well. Wrap cooled loaves tightly in plastic wrap and then foil.
For a stronger orange flavor, you can add more zest.
