Place kettle corn into a large bowl and Toss in broken pretzel pieces and M&Ms. Melt Vanilla Candy Melts in a microwave safe bowl on 50% power in 30 second intervals, stirring after each interval until melted and smooth. Drizzle half of melted chips over popcorn mixture, then stir, tossing gently a few times with a rubber spatula. Then drizzle remaining half of melted chips over popcorn, and gently stir mixture until evenly coated (don't over stir though or your sprinkles wont stick if the white chips begin to set and harden). Pour mixture into a single layer onto wax paper. Sprinkle entire mixture evenly with sprinkles (as many as you'd like) before vanilla chips set. Allow to cool and harden, then gently break into pieces and store in an airtight container. Note: I was able to fill 8 - 9 1/2"x 4" party treat bags about 2/3 full with this recipe, just to let you know so you have an idea for gift giving. Adapted from Bake at 350
