In a large mixing bowl, cream together softened butter and sugar until light and fluffy, about 3–5 minutes. Beat in egg, orange zest, and orange juice until incorporated.

In a separate bowl, whisk together flour, baking powder, and salt. Gradually add to wet ingredients, mixing on low until just combined.

Fold in chopped dried cranberries and white chocolate chips until evenly distributed.

Roll out cookie dough to about ½ inch thickness, cut star shapes, and place on a parchment-lined baking sheet.

Preheat oven to 350°F (180°C). Bake cookies for 10–12 minutes, until edges are golden and centers are slightly puffy.

Remove from oven, sprinkle with extra sugar while warm, and transfer to a wire rack to cool completely.
