they were called Danny-O bars, and I can still remember the commercial for them. The model bit into them and then say "SOooo, good! Tey were delicious. I have found a similar bar, made by blue bunny, except its pink inside, but also with that yogurt tartness.

what about Dannon Frozen Yogurt Parfait? In a cup. It was that was coated cardboard that used to be used for all their packaging, with the pull off lid. It was the BEST thing I have ever tasted, was available at GNC, when GNC was like a small health food store, not like they are today. We used to go jogging and then come to buy a dannon frozen yogurt parfait.
