Place puff pastry ontop; sprinkle with remainingmixture. Gently rollout to a 1/8-inch-thick rectangle,pressing sugar intodough. Lightly draw a linedown center of rectangle.Starting from edges, folddough halfway towardcenter, then fold edgesagain to reach center.(Folds should look like anopen book.) Fold onehalf over other half (as ifclosing the book). Wrapin plastic and freeze untilvery firm but not frozen,about 20 minutes.
Preheat oven to 425 degrees.Cut dough crosswise into1/2-inch-thick slices. Workingin batches, arrangeslices 2 inches apart on anungreased baking sheet.Flatten each cookie withthe heel of your hand toabout 1/4 inch thick.
