Millionaire pie is a no-bake American pie. This pie is a dish from the Southern United States and originally from South Carolina. Because it was so rich, it gave rise to the name. It is made of cream cheese (although this may not be traditional), coconuts, Cool Whip, crushed pineapple, and chopped pecans with a graham cracker crust, although the ingredients are modifiable. Condensed milk and heavy cream can also be added. Some versions use oranges as well. However, the whipped topping and crust are essential ingredients, although the type of crust (e.g. graham cracker, shortbread) can vary. Lemon juice has also been highlighted as a key ingredient, as it helps with thickening the filling. It is served chilled enough where the filling retains its shape.
