We've been enjoying Nikki's recipe for frozen Key Lime pie, and it brought to mind this recipe I came across last summer. :)
1 1/4 cups crushed pretzels
1/4 cup sugar
6T butter or margarine, melted
1 can (14oz) sweetened condensed milk
1/2 cup lime juice
1 envelope Kool-Aid Lemon Lime unsweetened drink mix
1 tub (8oz) Cool Whip, thawed, divided
*for added lime flavor, stir in 2T grated lime peel*
Mix crushed pretzels, sugar, and butter. Press firmly onto bottom and up the side of 9" pie plate. Refrigerate until ready to fill.
Combine condensed milk, lime juice and drink mix in large bowl until well blended. Remove 1/2 cup Cool Whip; refrigerate until ready to use. Gently stir in remaining whipped topping. Pour into crust.
Freeze 6 hours or overnight. Let stand at room temp 15 minutes or until pie can be cut easily. Garnish with reserved Cool Whip before serving. Store leftover pie in freezer.
