The Pennsylvania Dutch are known for producing quality goods, whether it's artisan wood furniture or delicious handmade foods. No other dessert is tied to the Amish country like the shoofly pie. Variations of the pie abound, but the most common form is akin to a rich coffee cake, with a sticky molasses bottom. Served warm with whipped topping, this favorite of the bakeries and restaurants of Pennsylvania owes it roots to the treacle tart dessert in England. There are various stories about the unusual name, but the most commonly held theory is that the sugary pies cooling in the windows attracted a fair amount of unwelcome flies.
