**Pop the Popcorn:** Prepare the popcorn according to package directions or using an air popper. Remove any unpopped kernels and place the popcorn in a large mixing bowl.
**Melt the Green Candy Melts:** In a saucepan or microwave-safe bowl, melt the green candy melts with 1 tablespoon of coconut oil (if using). Stir until smooth and fully melted.
**Coat the Popcorn:** Pour the melted green candy over the popcorn and gently toss to coat evenly.
**Spread on a Baking Sheet:** Transfer the coated popcorn to a parchment-lined baking sheet, spreading it out into a single layer.
**Melt the White Chocolate:** Melt the white chocolate chips with 1 tablespoon of coconut oil (if using) in a microwave-safe bowl. Drizzle the melted white chocolate over the popcorn.
**Add Sprinkles:** While the chocolate is still wet, sprinkle the red heart candies and holiday sprinkles over the popcorn.
**Let It Set:** Allow the popcorn to sit at room temperature until the chocolate hardens, about 15-20 minutes.
**Serve or Store:** Break the popcorn into pieces and serve immediately or store in an airtight container.
