This is very much a dessert from the 70s.  Brandy Alexander Pie together with its twin  Grasshopper Pie were all the fashion back then.  They are basically the same recipe but this one has brandy and creme de cacao and the other has creme de menthe and creme de cacao.  I liked this one, but I think you can see why they both went out of favor.
