COMBINE flour, baking soda and salt in small bowl. Beat butter, granulated sugar, brown sugar and vanilla in large mixer bowl. Add eggs one at a time, beating well after each addition; gradually beat in flour mixture. Stir in morsels and nuts (if desired). Drop by rounded tablespoon onto ungreased baking sheets.

BAKE in preheated 375°F oven for 9 to 11 minutes or until golden brown. Let stand for 2 minutes; remove to wire racks to cool completely.

TIP: If you like your chippers chewy, bake for 8 to 9 minutes. The centers will still look slightly wet and the edges will be golden brown. Let cool on cookie sheet for 2 to 3 minutes
