Popcorn

1. In a Whirlypop or large pot with a lid, pour in oil, salt, and popcorn kernels.
2. Place on stove over high heat, constantly shaking the pot.
3. After 2-3 minutes you will begin to hear the kernels pop. Continue to shake the pot so the kernels do not burn.
4. Popcorn is finished once there are a couple seconds in between each pop and the pot is filled. Take off the burner and pour it into a large bowl. Remove any unpopped kernels.

Marshmallow Filling

1. In a large pot add butter and marshmallows and place over medium heat.
2. Stir occasionally as the butter and marshmallows melt.
3. After 7-10 minutes the marshmallows should be completely melted and incorporated into the butter. Whip vigorously with a wooden spoon to get rid of any remaining clumps.
4. Once completely smooth remove from heat and add in vanilla, stirring to incorporate.

To assemble

1. Immediately pour the marshmallow mixture over the popped popcorn.
2. Stir the popcorn mixture until every popcorn kernel is evenly coated.
3. Spray hands with some cooking spray to prevent sticking and pack one big handful of popcorn together in the shape of a ball. Think like you are making and packing together a big snowball 
4. Place balls on a baking sheet and repeat until all the popcorn is used. Enjoy!
