Every holiday when my DD's were younger I made popcorn balls made with marshmallows and butter. We tinted them to match the holiday in question. I used the same recipe that you use for rice krispie treats, just substitute 6 cups of popcorn, for the rice krispies. Important note- If you want to make these, you must use plain, un-buttered, un-salted popcorn, or you will have a mess on your hands.
