Using an electric mixer, beat together the butter, granulated sugar, brown sugar, egg and vanilla on medium speed until smooth. In a separate bowl, sift together the flour, baking soda and salt. Turn the electric mixer to low and slowly add the dry mixture to the wet mixture. Stir in the chocolate chips.
With a 1-ounce ice cream scoop, drop the batter about 2 inches apart on ungreased cookie sheets. Bake until lightly browned, 8 to 10 minutes. Carefully remove the cookies to a wire rack to cool. Store in an airtight container.
