My mum used to make a luxurious pud in the 1970s called chocolate refrigerator cake. I've looked for it without success on t'internet.
It might even have been called an ice box cake (not sure) and might have been a Mary Berry recipe (not sure). Sponge fingers on the outside with a rich chocolate moussey filling, then covered all over with whipped cream. It was made in a terrine iirc.
Anyone have recollection of this dessert as I'd love to recreate it !
