Place oreos in a blender or food processor and pulse into crumbs.
Add to a medium mixing bowl with the softened cream cheese and mix with a hand mixer until well-combined.
Use a medium cookie scoop or tablespoon to scoop even amounts of oreo mixture out, and roll into balls in your hands. Place on a wax-paper lined plate or cookie sheet. Repeat until all the mixture is used. You will have 16-18 truffles depending on size. Place truffles in fridge for about 15 minutes (or freezer for about 5-7 minutes)
Melt the white chocolate bark in a cup or measuring cup that is deep enough for easier dipping. (Standard melting instructions are 60 seconds on 50% power, stir, and then heat at 50% power in 30 second increments until melted, stirring each time.)
Once melted, remove the truffles from the fridge or freezer, drop them into the melted chocolate one at a time and use a fork to scoop out, tapping the fork on the edge of the container to remove excess chocolate and smooth the surface. Place back on your wax paper covered plate, using a toothpick to help scoot it off the fork if necessary. Press a gummy eyeball into the top of the truffle immediately. Repeat until all truffles are made.
Place truffles in the fridge for about 10 minutes or so, until the chocolate sets. Store in an airtight container in the fridge.
