ounces pecan halves, toasted (1 cup)
ounces (2 sticks) unsalted butter, softened
cup confectioners' sugar, plus more for dusting
tablespoon pure vanilla extract
teaspoon coarse salt
cups all-purpose flour, sifted
Directions Preheat oven to 325 degrees. Break each pecan half into 2 or 3 pieces. Cream butter and sugar with a mixer until pale. With mixer running, add vanilla and salt, then reduce speed to low. Gradually add flour, beating until just incorporated. Stir in pecans until distributed evenly. Cover dough, and refrigerate until firm, 15 minutes (or overnight; let dough come to room temperature before using). Drop 2-tablespoon scoops of dough onto baking sheets, 2 inches apart. Bake, rotating sheets halfway through, until edges of cookies are golden, about 15 minutes. Let cool on sheets on wire racks for 5 minutes. Transfer cookies to wire racks, and let cool. (Cookies will keep, covered, for up to 2 days.) Dust with confectioners' sugar just before serving.
