Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, cream together the softened butter and granulated sugar using an electric mixer until light and fluffy.
Add the vanilla extract and orange zest, and mix until well combined.
In a separate bowl, whisk together the flour and salt.
Gradually incorporate the dry ingredients into the butter mixture, mixing until just combined.
Fold in the chopped dried cranberries with a rubber spatula until evenly distributed.
Scoop tablespoon-sized portions of the dough onto the prepared baking sheet, spacing them about 2 inches apart.
Gently flatten each cookie with the bottom of a glass or your hand.
Bake in the preheated oven for 20 minutes or until the edges are lightly golden.
Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a cooling rack.
Once cooled, dust with powdered sugar before serving.
