Preparation
Step 1
Preheat oven to 325°F.
Step 2
Pulse toasted pecans with 2 tablespoons confectioners sugar in a food processor until finely ground. Whisk together flour, salt, and baking powder in a bowl.
Step 3
Beat together butter, remaining 2/3 cup confectioners sugar, and vanilla in a bowl with an electric mixer at high speed until pale and fluffy, about 3 minutes. Add egg yolk and beat well. Add flour and ground-pecan mixture and mix at low speed until just combined, 30 seconds to 1 minute. (Dough will be crumbly but will hold together when squeezed.)
Step 4
Halve dough and roll out 1 half between 2 sheets of wax paper until 1/4 inch thick (about a 9-inch round). Cut out as many rounds as possible with cookie cutter and arrange about 2 inches apart on buttered large baking sheets, reserving scraps. Roll out and cut remaining dough in same manner. Gather scraps, then reroll and cut in same manner.
Step 5
Beat egg white until frothy, then brush tops of rounds lightly with egg white. Put a pecan half on top of each round, then brush pecan lightly with egg white.
Step 6
Bake cookies in middle of oven until tops are pale golden, 15 to 20 minutes. Cool cookies on sheets on racks 2 minutes, then transfer to racks to cool completely.
