Crush the Oreo cookies in a plastic bag with a rolling pin. Lay out the popcorn on a baking sheet lined with aluminum foil. Add the crushed Oreos to the popcorn and stir around.

Put the almond bark in a microwave safe bowl. Microwave for 30 seconds and stir. Microwave for 20 seconds more and stir. If the almond bark still has some lumps, microwave again for another 20 seconds.

Pour the smooth almond bark over the Oreo and popcorn mixture. Stir everything together with a spatula.

Serve while still a little warm, or you can put it in the fridge for an hour or so until the popcorn is somewhat hard.
