If trifle is indeed from the Devil then it's quite ironic that its a dessert that my mom saves to make once a year, for Christmas day. If you're not sure why I'm of the opinion that the dessert is born from pure evil - just click here for a Google image search (beware, not for sensitive viewers). ;)
From what I"ve read the earliest reports of a trifle-like dish stem from England in the 1590s - except that back then the ingredients were possibly simpler: thick flavoured cream, sugar, ginger and rosewater.
Trifles are quire different today - they contain sponge cake that's been soaked in alcohol (sherry, for example), pieces of fruit (often berries), custard, jelly (which I think our American friends call jello), and a whole lot of thickly-whipped cream. These ingredients are (as you can see from the pics) layered to form the multi-layered decadent pudding that's perfectly yummy.
