"A Sugar Pie has a single crust and is filled with a mixture of butter, flour, milk, eggs and brown sugar. When it bakes the filling turns into a caramel-like mixture. It’s originally from western European countries and popularized in the U.S. by the Amish. Sometimes the Old Fashioned Sugar Pie Recipe is referred to as ‘desperation pie’ because it could be made with ingredients that would always be on hand ‘on the farm’ much like the Buttermilk Pie, Vinegar Pie or Chess Pie."
