Add the vegetable oil into a large stockpot over medium-high heat. Place 4 popcorn kernels inside and cover with a lid.
Once the kernels have popped, pour the rest of the kernels inside and cover.
Shake the pot vigorously every few seconds to ensure the popcorn cooks evenly. Shake quickly, though, as you don't want the pot off of the heat for too long.
When the kernel popping slows down to about 3 seconds apart from each other, remove the pot from the heat. Give it one last good shake, and then dump the popcorn into a large bowl.
Pour the melted butter over the popcorn as evenly as you can and immediately give it many tosses to distribute the butter equally.
Sprinkle a little bit of the cheese powder over the popcorn. Toss the popcorn very well. Continue adding a little bit more of the cheese powder, tossing the popcorn well, until there is no cheese powder left. I usually begin tossing the popcorn with my hands about half-way through adding in the cheese powder.
VOILA! Enjoy your realistic, SUPER cheesy, vegan popcorn!
