Lemon Ice Box Cake

INGREDIENTS
1 (18.25 ounce) package lemon cake mix
2 (14 ounce) cans sweetened condensed milk
1/2 cup fresh lemon juice
1 (12 ounce) container frozen whipped topping, thawed

DIRECTIONS
Bake the cake in 2 layers as directed on package. When cool, slice each layer in half horizontally, making 4 layers. In a medium bowl, combine the 2 cans of sweetened condensed milk with the fresh lemon juice. Reserve half of the mixture and set aside. Use half of lemon/milk mixture to put between layers. With the reserved mixture, gently fold in the whipped topping, and use to frost the entire cake. Chill overnight before serving.
