Dad and Mom made this for my birthday, and it was one of the best cheesecakes I've ever had! Dad thought that the texture was especially good, And we were talking about how it would be really good with some fresh fruit on top! So try what you want with it! We only ate half of the cake that afternoon, because you really only need a small piece! :) -Emily

Citrus Cheesecake

Ingredients:
1/2 cup butter, softened
1/3 cup sugar
1 egg yolk
1/2 teaspoon vanilla extract
1-1/4 cups all-purpose flour
1 teaspoon grated lemon peel
FILLING
5 packages (8 ounces each) cream cheese, softened
1-3/4 cups sugar
3 tablespoons all-purpose flour
1-1/2 teaspoons grated lemon peel
1-1/2 teaspoons grated orange peel
1/4 teaspoon vanilla extract
5 eggs, lightly beaten
2 egg yolks, lightly beaten
1/4 cup heavy whipping cream
TOPPING
1-1/2 cups (about 12 ounces) sour cream
3 tablespoons sugar
1 teaspoon vanilla extract

Directions: In a large mixing bowl, cream butter and sugar until light and fluffy. Beat in egg yolk and vanilla. Combine flour and lemon peel; gradually add to creamed mixture. Mix until dough forms a ball and pulls away from the sides of the bowl. Divide dough in half; cover and refrigerate for 1 hour or until easy to handle. Remove sides of a 9-in. springform pan. Grease bottom. Between waxed paper, roll one half dough to fit bottom of pan. Peel off top paper; invert dough onto bottom of pan. Remove paper; trim dough to fit pan. Place on a baking sheet. Bake at 400° for 6-8 minutes or until light browned. Cool completely on a wire rack. Attach sides of the pan and grease sides. Pat remaining dough 1-1/2 in. up sides of pan, pressing dough to bottom crust to seal. For filling, in another large mixing bowl, beat the cream cheese, sugar, flour, peels and vanilla until smooth. Add eggs and yolks; beat on low speed just until combined. Stir in cream just until combined. Pour into crust. Return pan to baking sheet. Bake at 400° for 10 minutes. Reduce heat to 325°; bake 55-65 minutes or until center is almost set. Cool on a wire rack for 10 minutes. Carefully run a knife around edge of pan to loosen; cool 1 hour longer. Combine topping ingredients; spread over cheesecake. Refrigerate overnight. Remove sides of pan. Enjoy! Refrigerate leftovers.
