On a baking tray, lay out the popped popcorn.

Break up half of the pretzels and spread both the broken and whole pieces of pretzel over the popcorn.

Spread out the M&Ms over the popcorn.

Melt the candy wafers in the microwave in increments of 30 seconds, stirring between each interval, until melted and liquid.

Drizzle the melted candy wafers over the popcorn mix.

Add the sprinkles to the popcorn mix and toss everything to make sure the ingredients stick to each other.

Let the popcorn cool until the white chocolate has hardened, then break into clusters and serve.
