Peeps added these in 2007. I didn't see them till this year.
There's a little cocoa mixed in with the sugar coating. The flavor is subtle but nice and festive if floated on top of a cup of hot chocolate.
Each peeps bunny is 30 calories and surprisingly there is very little junk in a peeps ... just sugar, gelatin and corn syrup with only one preservative and some flavoring.
Here's what they look like and a good description on this blog
I bought the cocoa peeps at Target
