>>38751545My Mum makes the most delicious and easy trifle
You get some pre-made, plain sponge-cake, break it up and put it in a bowl, get two big cans of fruit salad in fruit juice (Nan would put in Ginger Ale at this point, but my mum didn't so it was more healthy), put a layer of custard on top of that, and then a layer of whipped cream on top of that.
Yum yum.
