Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. Beat in the eggs and add the vanilla extract. Mix until well combined.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the flour mixture into the butter mixture, mixing until just combined.
Fold in the dried cranberries, chopped pecans, and white chocolate chips until evenly distributed throughout the dough.
Using a spoon or cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheets, leaving space between each for spreading.
Bake in the preheated oven for 10-12 minutes or until the edges of the cookies are golden brown.
Allow the cookies to cool on the baking sheets for a few minutes before transferring them to wire racks to cool completely.
