Preheat the oven to 350°F (175°C) and 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, one at a time, followed by the vanilla extract.
In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Gently fold in the dried cranberries and chopped nuts (if using).
Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake for 10-12 minutes or until the edges are lightly golden brown.
Allow cookies to cool on the baking sheets for a few minutes before transferring them to wire racks to cool completely.
