Wellllllll I was at the South Carolina State Fair so you know I had to investigate. I have heard of them and by passed them last year to get the donut burger! But anyway it's now that they just batter the Oreo but after they are fried (needless to say I didn't see them use a temperature needle to make sure they were properly cooked!) they are buttered and covered with powdered sugar!
I really don't know how to describe it.....my mouth was confused and I didn't want to burn my tongue. Lets just say it's just something that you just have to try for yourself.
