Preheat your oven to 350°F (175°C) and prepare baking sheets with parchment paper.

In a large mixing bowl, cream together the unsalted butter, granulated sugar, and brown sugar until light and fluffy.

Add one room-temperature egg and beat until incorporated and smooth.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually mix into the wet ingredients until just combined.

Gently fold in dried cranberries, white chocolate chips, and orange zest until evenly distributed.

Drop portions of dough onto prepared baking sheets, spacing them about 2 inches apart.

Bake for 12-15 minutes until edges are light golden brown and centers are soft.

Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
