1. Prepare the Crust:

1. Preheat oven to 325°F (165°C). Line a baking sheet with parchment paper.
2. In a large bowl, cream together the softened butter, granulated sugar, and powdered sugar until light and fluffy. Beat in the vanilla extract and orange zest.
3. In a separate bowl, whisk together the flour and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Fold in the chopped dried cranberries.
4. Divide the dough in half. On a lightly floured surface, shape each half into a log about 1.5 inches in diameter. Wrap in plastic wrap and chill for at least 30 minutes.
5. Slice the chilled logs into 1/2-inch thick rounds and place them 1 inch apart on the prepared baking sheet. Bake for 18-22 minutes, or until the edges are just beginning to turn golden. Let cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
