This pie is a staple of Canadian prairie culture, consisting of a graham crumb pie crust that is filled with a creamy custard, then topped with an airy meringue. The custard is usually made with milk, sugar, cornstarch, egg yolks, vanilla, and salt, while the pie crust consists of graham crackers, sugar, butter, and maybe a bit of cinnamon.

Although flapper pie is notorious for the fact that it falls apart quite easily, preparing this dessert is certainly worth the effort. Before serving, it is typically sprinkled with breadcrumbs and left to chill in the refrigerator.
