In small bowl, combine flour, baking soda and salt. In large bowl, beat butter and sugar with electric mixer until light and fluffy. Add egg and vanilla; mix well. Add flour mixture, mixing until just combined. Stir in cereal and chocolate chips. Drop tablespoonfuls of cookie dough onto parchment-lined cookie sheets, about 2 in. apart.
Bake 10-12 minutes or until golden brown around edges. Cool cookies on cookie sheet 3 minutes. Transfer to cooling grid; cool completely.
