Finely ground Oreo Cookies in food processor. Put cookies and cream cheese in large bowl and mix thoroughly until no cream cheese shows.
Form 1- 1 1/2" balls using a melon scoop. Sometimes I have to roll them a little between my hands to make smooth. Place on cookie sheet lined with wax paper. Chill in freezer for as long as it takes to prepare chocolate coating.
Melt chocolate in non stick pot or double broiler with 1-2 tsp. of shortening over low heat. Take bon bons out of freezer and dip each in chocolate. Lift out with fork and place back on wax paper and chill. Repeat with white chocolate.
