Brown Sugar Cookies

0 Beat butter at medium speed with an electric mixer until creamy. Gradually add brown sugar, beating well. Add egg and vanilla and continue beating.
1 Combine flour, baking soda, and salt. Add to the butter mixture a little at a time and beat until well blended.
2 Preheat oven to 350F.
3 Roll dough to ¼ inch thickened between 2 sheets of wax or parchment paper. Cut into favorite shape, stars for me. Place 1 inch apart on ungreased baking sheets. Sprinkle cookies with decorator crystals.
4 Bake for 10 to 12 minutes or until golden. Let cookies cool on baking sheet for a minute. Transfer carefully to a wire rack to cool completely.
