My sister's co-worker brought these to a party and they were quite a hit. I don't know where the recipe came from originally. \"Bark\" is an artificial chocolate or vanilla candy coating/confectioner's coating used to make a treat called almond bark and can be found at most grocery stores near the chocolate chips. You can use chocolate chips and white chocolate chips if you don't have almond bark, but I have found that almond bark melts better and is easier to work with.
(16 ounce) package Oreo cookies, crushed
(24 ounce) package chocolate bark
Using a blender or hand held mixer, mix Oreos and cream cheese together.
Roll into walnut size balls.
Chill for an hour.
Melt approximately 3/4 package of white almond bark.
Stick a toothpick in an Oreo ball and dip it in the melted white almond bark.
Allow to harden on wax paper.
Takes about 15 minute.
While waiting, melt about 1/4 package of chocolate almond bark.
When Oreo balls are no longer sticky to the touch, decorate with drizzles of chocolate and white almond bark.
I just use a sandwich bag with a tiny hole cut in one corner to drizzle the almond bark.
