Pop the popcorn in your microwave.

When your popcorn is ready, pour it onto a large baking sheet.

On a double boiler, melt your white chocolate chips. (Be careful not to have any drops of water mix with the chocolate - it will ruin the batch.)

Stir frequently and scrape down the sides with a rubber spatula, until your chocolate mixture is completely melted. 

When the chocolate is melted, pour it over the popcorn. 

With clean hands, mix the chocolate through the popcorn.

Let the popcorn rest for at least 30 minutes before serving.
