Amy's Cheesecake

I got this recipe in college from some girl named Amy. It's a really, really good recipe. I can never get them to look very pretty, but the taste more than makes up for it! She has instructions for 3 different flavors of cheesecake. I have only made the berry and lemon, and they are both yummy.

Makes 2 cheesecakes!

2 nine inch graham cracker pie crusts

Filling:
3--8oz packages of cream cheese
1 c. sugar
1/4 t. salt
2 t. vanilla
3 eggs

Topping:
2 c. sour cream
3 T sugar
1 t. vanilla

Berry Cheesecake:
1 c. berries
1 egg

Pumpkin Cheesecake:
1 c. pumpkin pie filling
1/2t. pumpkin pie spice
1 egg

Lemon Cheesecake:
1 c. lemon curd
1/2 t. lemon juice
1 egg

Instructions:
Preheat oven to 3oo degrees. Beat softened cream cheese (microwave for 1 1/2 minutes to soften), sugar, salt, and vanilla. Add eggs. Use half the batter to fill each pie half full. With the remaining batter, mix in whichever kind of cheesecake you choose (for example, for lemon cheesecakes, mix the batter with 1 c. lemon curd, 1/2 t. lemon juice, and one egg). Spread the flavored batter over the cheesecake batter in the pie crusts. Bake for 50 minutes. Remove and cool for five minutes. While cooling, mix up the topping. Spread over baked cheesecakes and bake for ten more minutes. Chill before serving.
