Melissa, I like to 'surprise' people with Oreo Balls. NOT CLEAN, by ANY stretch of the imagination, but super easy, quick and delish! All you do is process a package of Oreo cookies in a food processor till they're all crumbs. Then add in a brick Cream Cheese and process till it combines and forms a ball. Roll them into balls, about 1" big and chill for about 30 minutes or so. Then, you can do whatever you want with them....sometimes I dip them entirely in melted chocolate of different colors, sometimes I melt colored chocolate and swirl on top by using a zip lock bag with a small whole cut out, sometimes I just dust with powdered sugar! To HELP a LITTLE, you can use the lower fat version of both the Oreos and the CC, and it tastes the same.
Have fun, whatever you decide to make!
(edited to fix my typo....Oreo BALLS, not Oreo BARS)
