3 cans sweetened condensed milk
2 pie crusts

Boil 3 cans of sweetened condensed milk for 2 1/2 hours. Water must always stay above the top of cans so you will need to add hot water as needed. Then remove cans from water; let cool, then open and pour 1 1/2 cans in each already baked pie crust. Top with Cool Whip.
