Seeing Mhays recipe suggestion reminded me of a recipe my Mother developed for a low carb, no sugar added cheesecake -- I've had it and it's actually pretty tasty.
PAM'S PUMPKIN CHEESECAKE
Butter
1/2 cup pecans, coarsely chopped
Two 8-oz. packages cream cheese, softened
1/2 tsp 3/4 cup Splenda
2 tsp vanilla
1 1/2 cups pure canned pumpkin (without any seasoning)
1/2 cup sour cream
4 eggs
1 1/2 tsp cinnamon
1 tsp ginger
1/2 tsp nutmeg
1/4 tsp ground cloves
1/4 tsp salt
1. Preheat oven to 300 F.
2. Butter the bottom and sides of a 9 inch springform pan. (Not absolutely necessary. You can do this in a round casserole dish and serve from the dish.) Sprinkle the bottom of the pan with chopped pecans, distributing evenly. (The nuts are optional.)
3. In a large mixing bowl, beat the cream cheese, Splenda, and vanilla until fluffy, stopping occasionally to scrape the sides of the bowl and beaters.
4. Add the pumpkin and sour cream, mixing thoroughly on medium speed. Add the eggs one at a time, mixing thoroughly after each addition. Mix in the cinnamon, ginger, nutmeg, cloves, and salt.
5. Pour the batter over the nuts in the pan. Bake for 60 to 70 minutes, or until a knife placed in the center comes out clean. Cool for 20 minutes before removing from the pan, and chill for at least 2 hours before serving.
