Stir together flour, soda, and salt. In a mixer bowl beat butter for 30 seconds. Add peanut butter and sugars; beat till fluffy. Add egg and vanilla; beat well. Add dry ingredients to beaten mixture; beat till well combined. Shape dough into 1 inch balls; roll in granulated sugar, if desired. Place 2 inches apart on an ungreased cookie sheet; crisscross with the tines of a fork. Bake at 375 for 9-10 minutes .

Cool about 1 minute before removing to a wire rack.

Makes 48. For an alternative, do not crisscross with a fork. Simply cook as directed. Upon removing cookies from the oven, place a chocolate candy Kiss in the center of each cookie, unwrappped of course.

Press slightly and cool completely. You can wrap cookie dough into a 1 inch ball around a candy kiss and cook as directed. This gives you a cookie with a chocolate center. This is also another great alternative.
