Freeze pie crusts at least 1 hour before filling. Meanwhile, refrigerate large mixer bowl and paddle until chilled.

For each pie: Beat 1 qt. ice cream and 1 tsp. cinnamon in chilled bowl with mixer fitted with chilled paddle attachment on low speed 30 to 40 sec. or just until blended. Spread half the ice cream onto bottom of 1 pie crust; cover with 1 cup Variegate. Freeze pie and remaining ice cream mixture 5 min. Immediately spread ice cream mixture over Variegate. Freeze several hours or overnight.

Repeat with remaining pie crusts and filling.
