In a large microwave-safe bowl, place 3 cups of the white chocolate chips and microwave in 30-second intervals, stirring in between, until completely melted and smooth.

Add 4 drops of red food coloring to the melted white chocolate and stir until evenly combined, creating a lovely pink hue.

Pour the melted pink white chocolate over the kettle corn in the bowl. Gently toss to coat the popcorn evenly.

Spread the coated popcorn onto a parchment-lined baking sheet.

Immediately sprinkle the remaining 1 cup of white chocolate chips and Valentine M&Ms over the popcorn.

Sprinkle with Valentine sprinkles.

Let the popcorn set completely at room temperature or in the refrigerator for about 15-20 minutes.

Once set, break apart any large clumps and store in an airtight container.
