I just had these at a Christmas party....to die for. I still can't believe that the only ingredients are oreos and cream cheese. The gal who brought them made them about the size of golf balls, so much larger than a "truffle"...but quite the treat! I love making "real" truffles with ganache, etc. but these were really amazing, too!
8 oz. cream cheese
1 pound Oreos
1 pound milk or dark chocolate
1/2 pound white chocolate
Grind Oreos to find powder in food processor. With a mixer, blend cookie powder and cream cheese until thoroughly mixed (there should be no white traces of cream cheese). Roll into small or large balls and place on wax-lined cookie sheet. Chill 45 minutes.
Line two cookie sheets with wax paper. In double-boiler, melt milk or dark chocolate. Dip balls and coat thoroughly. With slotted spoon or fork, lift balls out of chocolate and let excess chocolate drip off. Place on wax-paper-lined cookie sheet. In separate double boiler, melt white chocolate. Using a fork, drizzle white chocolate over balls. Let cool.
Store in airtight container, in refrigerator.
