Boston Cream Pie is a round cake that is split and filled with a custard or cream filling and frosted with chocolate. Not exactly your standard pie, but it's been around since 1855 or 1856 (two different sources with different dates).
According to Wikipedia, Boston Cream Pies were created by French Chef M. Sanzian at Boston's Parker House Hotel,
opened in 1855. This pudding/cake combination comprises two layers of
sponge cake filled with vanilla custard or crème pâtissière. The cake was
topped with a chocolate glaze (such as ganache) and sometimes
confectioner's sugar or a cherry. The cherry and sugar topping is rarely used any more.
real question is why this is called a pie? It's a cake, after all --
two layers of yellow cake filled with custard and topped with chocolate
frosting. Suggestions on why it's called pie are welcome. And here's an esoteric fact: The Boston cream pie is the official desert of the Commonwealth of Massachusetts.
This Retro Ad (3/29/68) from Jello-O Pudding has a quick and easy recipe for Boston Cream Pie. I really prefer making the cake, filling and ganache from scratch. You know I'm a sucker for good chocolate which for me will make or break the taste of a good Boston Cream Pie. However, if you don't have time, I've posted the Jell-O Pudding Boston Cream Pie below.

Pour mixture through strainer back into saucepan. Cook over medium-high heat, whisking constantly, until
