If you're going to put your trust in anything in this world, let it be Dairy Queen's Pumpkin Pie Blizzard. Since 1991, the old faithful frozen treat has made its triumphant return to the DQ menu every fall. And Blizzard lovers, for the 27th time in a row, here we go again. Beginning September 3, the Pumpkin Pie Blizzard will make its comeback as the September Blizzard of the Month. The base is a mix of DQ's classic vanilla soft serve and pieces of real pumpkin pie.
