Well, my close friend always makes vanilla and caramel cheesecake whenever we have parties. Here are her ingredients, which I think she also got, it from a website:
15 reduced-fat chocolate or vanilla wafer cookies, crushed (1/2 cup)
2 packages (8 ounces each) reduced-fat cream cheese (Neufchâtel) , softened
2/3 cup sugar
3 egg whites or 1/2 cup fat-free cholesterol-free egg product
2 teaspoons vanilla
2 cups vanilla low-fat yogurt
2 tablespoons Gold Medal® all-purpose flour
1/3 cup fat-free caramel topping
Will look for the website and post it here as soon as I find it.
