While you bag of popcorn is popping melt the butter in a large saucepan over medium heat.

Once melted add the marshmallows and stir until smooth.

Add in the white chocolate chips.

Remove from heat.

Filter out the popcorn kernels like I did in the video below.

Then add the popped popcorn into the marshmallow chocolate mixture.

Gentle stir to combine.

Add in the sprinkles and stir some more.

Form the popcorn into balls.

Add extra sprinkles if you would like.
