I always make a cheesecake for a party each year and usually stick to my favourite Baileys cheesecake recipe from BBC food. It's no-bake recipe which suits me as a) I don't like the heavier texture of the baked ones and b) my sister tends to make a baked version so I like mine to be different.
I've experimented with the ingredients a bit from time to time. An oreo base works well - stays nice and crunchy but not too solid. I use one third low fat cheese to two thirds full fat as that lowers the cals without affecting the consistency noticeably.
I'd like to make it with whipping cream instead of double but don't know whether that would work or whether it would de-stabilise after a while (and I love my slice of leftover cheesecake the next day).
