Boy, I cannot believe all the recipes out there using Oreos as a base for a holiday decorated cookie. I am sure you can use any crème cookie for these recipes, but make sure you temper the chocolate so they look their best.
I found this page with a bunch of chocolate dipped cookie ideas, and just really wanted to share this picture of the Oreo Snowmen!
