Place the popped popcorn and Oreos in a large bowl (I poured the popcorn out on a paper towel & picked out the kernels first). Heat the white chocolate candy coating in the microwave in 30 second intervals, stirring in between until melted and smooth.
Drizzle the white chocolate bark over the popcorn/Oreo mixture and stir to coat. Dump out on a large sheet of wax paper and spread into a single layer. Let cool and harden. Break into small pieces and serve.
*I used a homestyle popcorn without butter flavoring.
