Pop the popcorn based on the bag instructions and line a large baking sheet with parchment paper.

Spread the popcorn over the parchment paper. Sprinkle the broken pretzel pieces on top and gently mix them into the popcorn with your hands.

Place the candy melts in a microwave safe dish.  Heat in 20 second intervals (stirring after each one) until the melts are fully melted.

Drizzle half of the melted candy over the popcorn mixture and gently toss with a rubber spatula to coat the mixture with the candy melts.

Pour the remaining candy melts over the popcorn mixture and Sprinkle the M&Ms and Christmas Sprinkles on top.

Let the mixture cool completely so that the candy can harden.  Then break into pieces and serve.
