In a medium sized mixing bowl, use an electric hand mixer to combine the cream cheese, crushed Oreo, and pumpkin spice until combined.
Use a spoon or your hands to divide the mixture into 15 evenly sized balls and place them on a baking sheet lined with wax or parchment paper. Freeze the truffle balls for 30 minutes.
After you have frozen the truffle balls, microwave the chocolate on 30-second intervals until smooth and dip each ball in the white chocolate.
Return the truffles to the baking sheet, top them with a sprinkle of pumpkin spice if desired, and return them to the freezer for another 30 minutes.
Serve and enjoy!
Notes
I recommend placing any leftover Oreo pumpkin cream cheese truffles in an airtight container in the refrigerator. When stored properly, these homemade truffles will stay good in the refrigerator for up to 5 days or in the freezer for up to 2 months.
