Combine flour, baking soda and salt in a small bowl. Beat butter, granulated sugar, brown sugar and vanilla in large mixer bowl until creamy. Add eggs and beat well. Gradually beat in flour mixture. Stir in chocolate chunks. Using a tablespoon, scoop heaping spoonfuls of the batter onto ungreased baking sheets. If adding sprinkles, make sure to dip in sprinkles before baking.
Bake for 11 minutes or until golden brown. Cool on baking sheets for 2 minutes; remove to wire racks to cool completely.
