Step 1

In a stand mixer or with a hand mixer, beat Oreos and cream cheese together for 2 minutes. Add in the Reese's Peanut Butter Cups and beat until smooth. Fold in the Reese's Pieces.

Step 2

Refrigerate the truffle mixture for an hour.

Step 3

After refrigerating, roll the truffle mixture into 1 1/4 inch balls. Freeze the balls for 30 minutes.

Step 4

Melt the Ghirardelli wafers in a microwave safe bowl for about 30 seconds. Stir and melt in 10 second intervals until the chocolate is smooth.

Step 5

Using a fork or a dipping tool, dip the frozen truffle balls in the chocolate, covering completely. Allow the chocolate to drip then place them on a piece of parchment paper to set. While the chocolate is still wet, garnish the tops with additional Reese's Pieces.

Step 6

Allow the chocolate on the truffles to set completely. Store in an airtight container in the refrigerator.
