Forever Yours was always my favorite and they’d bring it back for a limited time now and then.  When they introduced the Milky Way Dark the Forever Yours name moved to an ice cream bar/treat.
 
Dark Milky Ways, fresh, right out of the box when the caramel layer pulls like melted cheese when you bite in to it…. Awwwwwww!
 
When I was younger there was a Hollywood Bar and Butternut bar that were similar but different.  Obviously not as good.
