Start by laying out a single layer of popcorn or kettle corn and pretzels on a baking sheet lined with parchment paper.
Grab two separate piping bags or Ziploc bags and fill them with the melted semisweet chocolate and melted white chocolate. Snip a small corner off each bag to create a makeshift piping tip.
Drizzle the melted semisweet chocolate all over the popcorn and pretzels, making sure to create lines that are very close together. You want most of the mix to be covered in chocolate goodness!
Sprinkle on the candy corn and M&M’s, and then drizzle the melted white chocolate over the top.
Finish off your spooky creation by adding a generous sprinkle of Halloween-colored sprinkles or nonpareils.
Pop the baking sheet into the freezer or refrigerator and chill until the chocolate is nice and firm, which should take about 20 minutes.
Once the chocolate is set, break your festive popcorn mix into pieces and get ready to enjoy a deliciously spooky snack at your Halloween party!
