Take 1/4 of the popped popcorn and place in a large bowl.
Melt 1/4 of the chocolate melts according to the package (generally 30 seconds and then check to see if melted). Once melted, pour onto the bowl of popcorn.
Use either a wooden spoon or clean hands to mix the chocolate into the popcorn until covered.
Quickly spread popcorn mixture onto a covered baking sheet and sprinkle on sprinkles while the chocolate is still melted.
Allow popcorn to harden and transfer into an airtight container until party time!
