Place your popcorn bag as per the instructions on the bag in the microwave.
Once your popcorn is done, add in your white chocolate chips in a small bowl and heat the chocolate in 30 second intervals and mix in between until the chocolate is fully melted.
In a large bowl, add in your popcorn, salt, melted white chocolate, m&ms and sprinkles and toss until well combined.
Serve and enjoy!
