Ingredients
Crust:
2 cups graham cracker crumbs
1/4 cup firmly packed brown sugar
1/2 cup light butter, melted
Pie:
1 cup light whipping cream
1/2 cup sugar
1 (12-ounce) can fat free sweetened condensed milk
3/4 cups key lime juice
1 tablespoon key lime zest
1 pint fat free half-and-half
Fresh lime slices. for garnish

Directions
Preheat oven to 350 degrees F.

In a medium bowl, combine cracker crumbs and brown sugar. Stir in melted butter. Press the mixture firmly into bottom and up sides of a 10-inch spring form pan. Bake for 8 minutes and let the crust cool completely before spreading the pie filling over it.

In a large bowl, with an electric mixer at medium speed, beat cream until slightly thickened. Gradually add the sugar, beating until soft peaks form. Add condensed milk and beat until stiff peaks form. Beat in lime juice, lime zest, and half-and-half. Once the mixture as reached desired flavor and consistency, gently spread pie filling over cooled crust. Cover and freeze for 4 to 6 hours or until firm. Cut into wedges and garnish with fresh lime slices, serve cold.
