As a teen I had an aunt (former, by marriage, so I can't ask her now...) who made a matza cake every Passover that I'd so love to find a recipe for. The matzas were soaked in wine until soft, then layered with a chocolate mousse or similar, which also iced the sides and top. You'd end up with a thin slice with at least 12 matzas. So good. Her family was not Jewish, so it wasn't a handed down recipe - probably from a cookbook (this was the 80s).
Anyone have something similar? I've been searching for years but haven't found the same thing yet.
