Goetze's Caramel Creams, that is.
Go here if they're not available in your area. It's actually a pretty cool website (the home page, anyhow.)
I ate them growing up and rediscovered them during our east coast trip, this past summer. During my recent visit, they were at Big Lots!
The white cream/sugar mixture in the middle is electric in the small buzz it gives. It melts away all too quickly. But the caramel that remains is pretty good. And I'm not normally a big fan of caramel.
