Place a few Oreos in a resealable bag and crush them with a spoon. Repeat until all Oreos have been reduced to little crumbles.
Combine cream cheese and Oreos in a mixing bowl until a dough forms. Mold the dough into 1-inch cones (or ghost shapes). Place on a baking sheet or plate and put in the freezer for at least 20 minutes.
Pour white chocolate chips into a microwave-safe bowl and microwave for 30 seconds, stir, then microwave for another 30 seconds. Repeat until all of the chips are melted.
Holding the ghosts upside-down, dip them into the melted white chocolate, using a spoon to help coat the sides. Place on a plate or baking sheet and let dry for about 10-15 minutes. Use a toothpick to draw on faces.
