Oreo Truffles

These are SO yummy, and you could do so many different variations. But here is the basic recipe that we use most often.
Ingredients:
-8 ounces softened cream cheese
-18 ounce package of Oreo cookies, crushed
-2 cups semisweet or milk chocolate chips
-White chocolate
-1 T shortening

-Mix cream cheese with electric mixer until fluffy, add the crushed Oreos and beat on high until well mixed
-Form into one inch balls, (I use a 1/2 T to measure the size)
-Chill in the freezer for about 2 hours
-Melt the chocolate chips and shortening with a double boiler or in the microwave
-Dip the Oreo balls completely into the melted chocolate using tongs or a toothpick
-Put on wax paper, after the chocolate hardens, drizzle melted white chocolate on top
-Keep in the refrigerator
