Lots of great deserts require wine or other alcohol. English trifle is perhaps the most forgiving and easiest to make (almost any dessert wine will work with it, though sherry or madeira is best ... presumably you didn't make that, or even port, but basically have a sweet wine with lots of residual sugar but no rancio). Baba rhum can be made with wine instead of rum, though it is a bit different. And there is always fruitcake ....
