My fave is made using brioche or waffles. You layer lindt chocolate broken between layers and raspberries (or banana's) and then poor over the custard, top with more chocolate and fruit and then poor the custard mix over, you bake uncovered for about 30 mins, then cover with foil if chocolate is starting to burn and bake for another 15-20 mins. Its absolutely DIVINE! Same again with brioche or croissants, but I tend to butter the bread or croissants with nutella first
