If I don't have kettle corn on hand, I microwave a bag of lite popcorn, put 1 T of soft butter over the popped corn , push it down into the middle of the hot popcorn and push it around with a spoon. Then I sprinkle 1 packet of Splenda in the bag. Shake well. Tastes great. I may have defeated the purpose of buying lite popcorn and then adding real butter, but I needed something to help the sweetner stick. If you melt the butter and then pour on, you get some of the popcorn too wet. When there's a will, there's a way. :-D
