Want something big for your Thanksgiving dessert buffet? This layered trifle recipe is a showstopper. Thin layers of spice cake give the old-fashioned trifle a modern look, but you can also cut the layers into large cubes if you prefer. However you prepare it, refrigerate the trifle at least four hours so that the layers of cake and custard can meld. Or make it a day in advance and top with the remaining whipped cream (step 6) just before serving.
