Begin by preparing 16 cups of popcorn using your preferred method—air-popping or microwave popping works best. Be sure to sift through the popped popcorn and remove any unpopped kernels. Transfer the fluffy popcorn to a large mixing bowl, creating the delightful base for your Ghost Popcorn Balls.

In a large pot, melt 10 ounces of mini marshmallows and ¼ cup of butter over medium heat. Stir continuously for about 5 minutes until the mixture is smooth and glossy, ensuring it doesn’t stick to the bottom of the pot. This gooey blend will serve as the wonderful binding agent for your Ghost Popcorn Balls.

Once melted, quickly pour the warm marshmallow mixture over the popped popcorn in the large mixing bowl. Use a spatula to gently fold and coat each piece of popcorn, ensuring every bit is covered with the sticky sweetness. Continue mixing until the popcorn is evenly coated, which should take about 2 to 3 minutes.

Lightly butter your hands to prevent sticking, then take small handfuls of the popcorn mixture and shape them into round balls about the size of a fist. Place each ball onto a lined baking sheet, leaving space between them to allow for any slight expansion as they cool. You should aim to make 10 to 12 hearty Ghost Popcorn Balls.

Allow the shaped popcorn balls to cool and firm up at room temperature. This process usually takes about 30 to 60 minutes, depending on your ambient conditions. You'll know they are ready when they hold their shape and are no longer sticky to the touch, creating the perfect treat for your Halloween festivities.

While the popcorn balls cool, melt the Wilton bright white candy melts according to the package instructions. Once melted, dip the tops of each cooled popcorn ball into the warm candy coating. Quickly sprinkle on candy eyeballs before the coating sets, giving your Ghost Popcorn Balls their adorable, spooky look.

Place the coated popcorn balls back onto the lined baking sheet and allow the candy coating to set completely, which may take an additional 15-20 minutes. Once firm, your delicious Ghost Popcorn Balls are finished and ready for serving at your Halloween party, providing joy and whimsy to all who partake.
