Sehr interresant. Apparently the form "stollen" as fruitcake is used with reference to cooking. Elsewhere it can mean tunnels (or adits, drifts, or mining galleries) or cleats (as on shoes). So, it may mean something, but the reference is somewhere between vague and ambiguous.
STOLLEN is also TUNNEL in German
