Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 3-4 minutes.
Beat in the eggs one at a time, then stir in the vanilla extract.
In another bowl, mix together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined.
Gently fold in the dried cranberries, white chocolate chips, and chopped pecans (if using) until evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, leaving space between each cookie for spreading.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden but the centers are still soft.
Remove from the oven and allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Arrange the cookies on a decorative plate, and consider drizzling some extra melted white chocolate over the top for an elegant touch. Enjoy with a glass of milk!
