Add eggs, one at a time, beating well after each addition. Gradually beat in flour mixture. Stir in nuts (if wanted). Drop by rounded tablespoon onto ungreased baking sheets.
Bake for 9 to 11 minutes or until golden brown. Cool on baking sheets for 2 minutes; remove to wire racks to cool completely.
