Step 1

Heat oven to 325 degrees F. Combine graham cracker crumbs and sugar. Add melted butter and stir until evenly moistened. Press mixture into bottom and sides of a 9-inch pie plate to form crust. Bake 10 minutes or until crust begins to brown. Cool 15 minutes on wire rack.

Step 2

Whisk sweetened condensed milk, lime juice and sour cream in large bowl until blended. Stir in lime peel. Pour filling into crust. Bake 7 to 10 minutes or until tiny bubbles begin to form on surface of pie. Cool completely on wire rack.

Step 3

Beat cream, powdered sugar and vanilla in large mixing bowl with electric mixer on medium speed until stiff. Top pie with whipped cream. Chill at least 1 hour before serving. Best served the same day.
