Heat oven to 375 degrees F. Line a large cookie sheet with parchment or lightly grease.
Cream butter and sugar in medium mixer bowl until light and fluffy. Beat in egg until thoroughly blended.
Combine dry ingredients; stir into butter mixture until thoroughly blended.
Drop batter by small teaspoonfuls onto prepared baking sheet, about 2 inches apart. Bake until edges are golden brown, about 9 minutes. Remove from oven and let cookies sit on sheet for 1 minute before removing with a spatula and transferring to wire rack to cool completely.
Note: The batter will be rather soft. The recipe makes exactly 2 dozen cookies so don't be tempted to eat any of the dough! I used an ice teaspoon to drop the dough, and make sure they are equal in size. The cookies crisp up as they cool.
