Preheat the oven to 350°F (175°C).
In a mixing bowl, cream together the softened butter and powdered sugar.
Add vanilla extract and orange zest to the creamed mixture.
In a separate bowl, combine the all-purpose flour, salt, and chopped cranberries.
Gradually mix the dry ingredients into the wet ingredients until just combined.
Form the dough into small balls (about 1 inch in diameter) and roll in granulated sugar.
Place the dough balls on a baking sheet lined with parchment paper, spacing them about 2 inches apart.
Bake for 12-15 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
