When it comes to the "Limited edition" flavors from Nabisco, I confess, I've become a little obsessed, to the point where I get multiple tags on Facebook whenever a new one is annoucned. Some of the Limited Edition flavors have been disappointing (Brownie Batter, I'm looking at you), while others have been triumphs (Hello, Toasted Coconut, how I miss you so!). The Cinnamon Bun ones are definitely in the "winning" category.
The true star of this cookie is the cream, though: it's a smoother consistency than the usual Oreo cream, and tastes very much like the creamy icing you find atop a cinnamon roll. There are hints of cinnamon in the cream, too--I just wish the ratio of cream to cookie were a little higher in this one.
