Press 2 cups dough onto bottom of prepared pan. Spread raspberry preserves evenly over the top of the crust.

Remove top sheet of waxed paper and cut dough into 1/4-inch-wide strips. Place dough strips over jam-filled crust in a lattice design.
Bake in the center of preheat oven for 35 to 40 minutes, or until lattice crust is golden brown and firm. Remove from the oven and let cool in the pan. Sprinkle top with powdered sugar and cut into rectangles or squares.
