Combine the ingredients in a large bowl, tossing together the popped popcorn, candy corn, mini pretzels, roasted peanuts, and white chocolate chips until evenly distributed.

Melt the butter in a small saucepan over low heat, stirring occasionally until smooth and golden.

Drizzle the melted butter over the popcorn mixture while stirring gently to coat.

Serve right away or store in an airtight container for later.
