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

Cream together the unsalted butter, granulated sugar, and light brown sugar for 2-3 minutes until light and fluffy.

Add the egg, vanilla extract, and grated orange zest to the mixture and beat until well combined.

In a separate bowl, whisk together the flour, baking powder, and fine sea salt. Gradually blend this into the wet ingredients.

Fold in the fresh cranberries and white chocolate chips.

Scoop the dough into balls and place them on the prepared baking sheet, spaced about 2 inches apart.

Bake in the preheated oven for 12-15 minutes until the edges are golden brown.

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