In a medium bowl, whisk together flour, pie spice, and salt. Add flour mixture to butter mixture all at once; beat on low speed just until combined.
On a lightly floured surface, shape dough into a 6-inch disk; wrap in plastic wrap and refrigerate for 1 hour.
Preheat oven to 350°. Line 2 baking sheets with parchment paper.
Unwrap dough and let stand at room temperature until slightly softened, 10 to 15 minutes. On a lightly floured surface, roll dough to ¼-inch thickness. Using a floured 2-inch round cutter, cut dough, rerolling scraps as needed. Place at least 1 inch apart on prepared pans.
Bake until bottoms are lightly golden, 8 to 10 minutes. Let cool on pans for 2 minutes. Transfer to wire racks and let cool completely.
