Begin by popping the popcorn kernels using a popcorn maker or microwave, following the package directions.

In the bowl with your freshly popped popcorn, gently toss in the broken pretzel pieces and festive M&Ms.

In a microwave-safe bowl, measure out the vanilla candy melts and heat them on 50% power in 30-second intervals, stirring between each interval until smooth.

Drizzle half of the melted candy over the popcorn mixture and toss. Repeat with the remaining candy.

Line a baking sheet with wax paper and spread the coated popcorn mixture evenly. Sprinkle festive Christmas sprinkles while still sticky.

Allow the Christmas Crunch to cool completely at room temperature for about 30 minutes.
