In a separate mixing bowl, beat the butter, granulated sugar, and powdered sugar together until light and fluffy. Add the egg, vanilla extract, and salt and mix until well combined. Slowly add the flour mixture to the butter mixture, and mix until just combined. Roll the dough into small balls, about 1 inch in diameter. Place the dough balls on the prepared baking sheet, spacing them about 2 inches apart. Press the cookies down slightly with a fork to create a crisscross pattern. Bake the cookies for 12-15 minutes, or until they are golden brown. Let the cookies cool...
