I decided to try out a Weight Watcher recipe I've been holding in a file for awhile. I adapted it to the supplies I had on hand, but these gals still turned out to be tasty, and a lot lighter than a traditional popcorn ball.
To make a light vesion of popcorn balls, take 1 bag of 100 calorie buttered popcorn, cook according to directions. Remover kernals, and add to a 8x8 baking dish.
Melt 6 pieces of caramel in the microwave (you can also toss in 1 T of chocolate, I didn't-they used 5 pieces WW candy that is a caramel/chocolate mix, I only had caramel pieces on hand). Stir and add 1 t. of milk.
Pour over the popcorn and mix. It won't mix too well, there will be some chunks, you'll be mixing several more times, so it should be fine.
Place this mix in a bowl, and toss 5 large marshmallows on top.
