We're going to do a (fairly informal) Christmas dessert competition amongst some extended family, I think the plan will be to have it as a late Christmas lunch dessert or sometime in the afternoon if everyone is too full. There will be four entries, I think, and I won't know what the other three people are making. So think everyone having a small slice or spoonful of the dessert so they can pick a favourite.
What kind of thing could I make, ideally a day or two in advance, or much of the work done in advance anyway, that would be a bit different? I'm not thinking Christmas cake, mince pies, Christmas pudding. More like: pavlova, or an interesting trifle, or some sort of jazzed up cake. But if it has a festive twist, like idk an orange and cranberry chocolate cheesecake, then great. Has anyone got any recommendations?
One person is GF and is never fussed if she can't eat something but I'd like to include her and have it be GF if possible.
tl;dr what dessert could I mostly make in advance, ideally GF, seems a bit festive
