Pop the Popcorn: Prepare the popcorn according to the package instructions, making sure to remove any unpopped kernels. Place the popped popcorn in a large mixing bowl.
Melt the Peanut Butter: In a microwave-safe bowl, heat the peanut butter until it's smooth and pourable. Start with 30-second intervals, stirring in between until it's fully melted.
Pour and Mix: Drizzle the melted peanut butter over the popcorn and gently toss to coat the popcorn evenly.
Dust with Sugar: Sprinkle the powdered sugar over the peanut butter-coated popcorn and mix again to ensure even coverage.
Add the Mix-Ins: While the peanut butter and powdered sugar are still warm, quickly add the M&Ms or Reese's Pieces, white chocolate chips, mini peanut butter cups, chocolate morsels, butterscotch morsels, and white chocolate morsels. Gently mix to distribute the candy throughout the popcorn.
Add Some Halloween Magic: While the mixture is still slightly tacky, shake on the Halloween sprinkles for a festive touch. You can get creative with different shapes and colors to match the spooky theme.
Cool and Set: Allow your Halloween Monster Munch to cool and set for about 15-20 minutes, or until the peanut butter and powdered sugar mixture solidifies.
Serve and Share: Once your monster munch is ready, scoop it into bowls or Halloween-themed bags and serve. It's perfect for sharing with family, friends, or as a delightful Halloween party treat.
