New York Cheesecake

Why I Love This Recipe
This is a cheesecake recipe that I found on Better Homes & Gardens. The only thing I changed was that I substituted a 1/2 teaspoon of lemon extract for the shredded lemon peel (the cheesecake had a nice lemony flavor to it!).
Ingredients You'll Need
2 cups finely crushed graham cracker crumbs
1/2 cup butter or margarine, melted
5 (8 oz.) packages cream cheese, softened
1 3/4 cups sugar
2 Tbsp. all-purpose flour
1 1/2 tsp. vanilla
5 eggs
2 egg yolks
1/2 cup whipping cream
1 tsp. finely shredded lemon peel
Directions
Preheat oven to 325 F.
To make the crust: Combine graham cracker crumbs and melted butter or margarine; stir until well combined; press onto bottom and 2 1/2 inches up the sides of a 9-inch springform pan.
To make the filling: Mix cream cheese, sugar, flour and vanilla; beat with electric mixer until fluffy; add eggs and egg yolks, beating on low speed just until combined; stir in whipping cream and lemon peel; pour into pan.
Place pan in a shallow baking pan in oven; bake for about 1 1/2 hours or until center appears nearly set when shaken.
Cool 15 minutes; loosen crust from sides of pan; cool 30 minutes more; remove sides of pan; cool completely.
Chill 4 to 24 hours in refrigerator.
