Traditional British trifle, often known as Sherry trifle is usually made up of layers of sponge fingers or sponge cake which is soaked in fortified wine or brandy, jelly or fruit coulis/confit, custard, and whipped cream. Because classic trifle contains eggs and dairy it's not suitable for vegans. Sometimes, it's not even vegetarian due to the gelatin if there is a jelly component.
