1In 5-quart Dutch oven, melt butter over low heat. Stir in marshmallows; cook and stir about 10 minutes or until marshmallows are melted. Remove from heat.
2Add remaining ingredients; stir until well coated. Form into 15 balls, about 1/2 cup each. (If needed, spray hands with cooking spray to keep from sticking.) Wrap popcorn balls in waxed paper or foil.
