The Origins of Boston Cream Pie
A Dessert Born in a Hotel
Boston Cream Pie was first created in 1856 at Boston’s famed Parker House Hotel (now the Omni Parker House). French chef Augustine Francois Anezin, who worked at the hotel, is credited with adapting French pastry techniques to create this American classic.
Why Is It Called a Pie?
In the 19th century, the terms “pie” and “cake” were often used interchangeably. The dessert was baked in pie tins, which were more common than cake pans at the time, leading to its misleading name.
Official State Dessert
In 1996, Boston Cream Pie was declared the official dessert of Massachusetts, cementing its place in culinary history.
