As for these cookies, I don't know...The Creamsicle Oreos are fucking gross, I don't know how you can ruin Creamsicle, but Oreos managed to do it and Candy Corn is only tolerable in mild doses to me, so I don't think these will turn out good.
I either prefer the regular/double-stuff Oreos in milk or the Mint Oreos. Crush up some mint oreos in some brownie mix, add a little mint extract and you have some brownie goodness. I've even topped them with the Andes mint candies from time to time. The co-workers LOVED my ass whenever I would bring those in.
