Butterscotch Pecan Thins

Directions

1. 1
   In a bowl with an electric mixer cream the butter with the brown sugar until the mixture is light and fluffy and beat in the egg and the vanilla.
2. 2
   Into the bowl sift together the flour, the baking powder, and the salt, beat the dough until it is firm enough to handle.
3. 3
   Halve the dough and on a piece of wax paper form each half into a 6-inch log, using the wax paper as a guide.
4. 4
   Chill the logs, wrapped in the wax paper, for at least 4 hours or overnight.
5. 5
   Preheat the oven to 350F.
6. 6
   Cut the logs into 1/4-inch-thick slices with a sharp knife, arrange the slices 3 inches apart on lightly buttered baking sheets, and press a pecan half onto each cookie.
7. 7
   Bake the cookies in batches in the middle of the oven for 10 to 12 minutes, or until they are golden, and let them cool on the baking sheets for 1 minute.
8. 8
   Transfer the cookies to racks and let them cool completely.
