Split-Second Cookies

Directions

1. Preheat oven to 350°. Cream butter and sugar until light and fluffy. Beat in egg and vanilla. In another bowl, whisk together flour, baking powder and salt; gradually beat into creamed mixture.
2. Divide dough into four portions; shape each into a 12x3/4-in. log. Place 4 in. apart on two greased baking sheets. Make a 1/2-in. depression down center of each log; fill with jam.
3. Bake until lightly browned, 15-20 minutes. Cool 2 minutes. Cut diagonally into 3/4-in. slices. Remove from pans to wire racks to continue cooling.
