Help me identify the dessert?

My wife ate this dessert as a child and has never been able to find it again- but the problem is, she can’t even remember the name. It has a hard layer of chocolate on top and it’s whip cream and chocolate layering inside.

I thought it was a type of tiramisu but she’s adamant it’s something different entirely.
