This recipe is from around 1945. I don't know the origin...my Mom has it listed as 'My Sister's Cheesecake' on her recipe cards. It is a simple recipe with only 5 or 6 ingredients, but it is very light and creamy and totally delicious. You can make a smaller cake by using two packages of cream cheese and reducing sugar to 1/2 cup and using 2 eggs, or make a larger one by increasing to 4 cream cheese and using one cup sugar and 4 eggs.
