Preheat your oven to 350°F (175°C).
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth.
Beat in the eggs one at a time, then stir in the vanilla.
In a separate bowl, combine the flour, baking soda, and salt.
Gradually blend the dry ingredients into the wet mixture.
Fold in the chocolate chunks until evenly distributed.
Drop spoonfuls of dough onto ungreased baking sheets.
Bake for 10-12 minutes or until the edges are lightly golden.
Remove from the oven and let cool on the baking sheets for 5 minutes.
Transfer to wire racks to cool completely.
