2 tbsp. sugar
1/2 stick (1/4 c.) unsalted butter, melted and cooled
1 1/4 lbs. (2 1/2 (8 oz.) pkgs.) cream cheese, softened
3/4 c. sugar
1 c. sour cream
3 tbsp. all purpose flour
3 lg. eggs
3/4 c. Key lime juice
1 tsp. vanilla
Crust: In a bowl, stir together the crumbs and the sugar and stir the butter in well. Pat the mixture evenly onto the bottom and 1/2 inch up the side of a buttered 10 inch springform pan and bake the crust in the middle of a preheated 375 degree oven for 8 minutes. Cool completely.
Filling: In a bowl with an electric mixer beat together the cream cheese and the sugar until the mixture is smooth, beat in the sour cream, the flour, the eggs, the lime juice and the vanilla. Mix until smooth.
Pour the filling over the crust. Bake the cheesecake in the middle of a preheated 375 degree oven for 15 minutes, reduce the temperature to 250 degrees, and bake the cheesecake for 50 to 55 minutes more, or until the center is barely set.
Let the cheese cake chill. I stuck mine in the freezer for a few hours. It was perfect!
Top with whip cream and enjoy!
