Cook 2 bags of microwave popcorn and put in a big bowl. (So the bowls half full)
Don't forget to take out the hulls so you don't bite one.
Melt the butter in the microwave (microwave safe bowl) until it melts. (About 45 seconds)
Add brown sugar and mix/sguish it.
Then, put in the microwave for 45 seconds. Do that twice and stir each time.
Add 14 marshmallows and then melt again for about 1 minute.
Be careful pouring it because it is very hot.
Hopefully your caramel corn turns out great. Now you can impress your friends with a great snack. They might even fight over it.
