This was a huge hit today; it was also easy to make. Today, I just served it in a prepared pie crust; however, this could easily be dressed up to serve as a traditional cheesecake in a spring form pan with a homemade graham cracker crust. I'd probably just make one batch of the regular cheesecake filling and then a separate batch of the pumpkin filling.
2 (8 ounce) packages cream cheese, softened
1/2 cup white sugar
1/2 teaspoon vanilla extract
2 eggs
1 (9 inch) prepared graham cracker crust
1/2 cup pumpkin puree
1/2 teaspoon ground cinnamon
1 pinch ground cloves
1 pinch ground nutmeg
1/2 cup frozen whipped topping, thawed
Preheat oven to 325 degrees F (165 degrees C).
In a large bowl, combine cream cheese, sugar and vanilla. Beat until smooth. Blend in eggs one at a time. Remove 1 cup of batter and spread into bottom of crust; set aside.
Add pumpkin, cinnamon, cloves and nutmeg to the remaining batter and stir gently until well blended. Carefully spread over the batter in the crust.
Bake in preheated oven for 35 to 40 minutes, or until center is almost set. Allow to cool, then refrigerate for 3 hours or overnight. Cover with whipped topping before serving.
Update (12/23/2010): Today, I made a new version of this cheesecake. I used three 8-0z packages of cream cheese (instead of two), 3/4 c sugar (instead of 1/2 c), and added 1/2 c of sour cream (after adding the eggs). I also used 1 c of pumpkin pie filling instead of pumpkin and all the spices. I made it in a springform pan with a graham cracker crust: (1 c graham crackers, 5 T butter, and 1/8 c sugar). I baked it at 350 degrees for 40 minutes.
