12 ounces frozen limeade concentrate, thawed
2 tablespoons key lime juice or 2 tablespoons lime juice
14 ounces sweetened condensed milk
12 ounces fat-free cool whip, thawed
In large bowl, combine limeade with lime juice and stir well. Add sweetened condensed milk, and stir until smooth and uniform. Fold in cool whip until smooth, being careful not to stir to the point that the cool whip breaks down. Pour into individual bowls or one large freezer-safe container. Freeze four hours or until set.
