Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper if desired.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In another bowl, whisk together the flour, baking soda, and salt. Slowly incorporate the dry ingredients into the wet mixture until just combined.
Gently fold in the dried cranberries and white chocolate chips, if using.
Using a cookie scoop or tablespoon, drop the dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.
