National Boston Cream Pie Day is celebrated on July 27 each year. This day honors the delicious dessert known as Boston Cream Pie, which is actually a cake made of two layers of sponge cake filled with vanilla custard or cream and topped with a rich chocolate glaze. The dessert originated in the late 19th century and is often associated with the city of Boston, Massachusetts. It was first created by a French chef at the Omni Parker House Hotel and has since become a beloved treat across the United States, enjoyed by many on this special day.
