I tried making the Popcorn Brittle in Cooking Light but it had molasses in it and that did NOT taste good!

This is much better.

Popcorn Brittle
1 1/2 cups sugar
1/4 cup water
3 tablespoons corn syrup
1 tablespoon light margarine
1 tsp baking soda
3 cups popped 94% fat-free butter flavor microwave popcorn
1/4 teaspoon salt

Line cookie sheet with foil and spray with cooking spray. Pop bag of microwave popcorn. Smash 3 cups of the popcorn; set aside. In medium saucepan, bring sugar, water and corn syrup to a boil. Boil until it reaches “hard ball” stage on candy thermometer. Add margarine, baking soda and salt. Combine well but do not stir too much or it loses the fluffiness. Continue to boil until lightly golden. Add popcorn and pour onto prepared cookie sheet.
