Directions
1. Preheat oven to 375 degrees F. 
2. For crust, stir together crushed graham crackers and cinnamon in a medium mixing bowl. Sprinkle onto bottom and 1 inch up sides of a well-greased 8- or 9-inch springform pan. Set pan aside. 
3. For filling, combine cream cheese, sugar, flour, vanilla, and, if desired, lemon peel in a large mixing bowl. Beat with an electric mixer on medium speed until combined. Add the refrigerated or thawed egg product all at once, beating on low speed just until combined (do not overbeat). Stir in milk. 
4. Pour filling into crust-lined pan. Place springform pan in a shallow baking pan. Bake in the preheated oven for 45 to 50 minutes for an 8-inch pan or 35 to 40 minutes for a 9-inch pan, or until center appears nearly set when gently shaken. 
5. Cool in springform pan on a wire rack for 15 minutes. Loosen crust from sides of pan with a thin-bladed knife or narrow spatula and cool 30 minutes more. Remove sides of pan; cool 1 hour. Cover and chill at least 4 hours or up to 24 hours. Top with nonfat sour cream and spoon on seedless red raspberry preserves; swirl with a spoon. Makes 12 to 16 servings.
