My cousin Grace made this delectable chocolate cheesecake for Christmas. Unlike the heavy cheesecakes you find at Cheesecake Factory (one slice takes me a couple sittings to finish), this was light and fluffy, with a home-made Oreo crust. She substituted most of the sugar in the recipe 1:1 with Splenda and used low-fat sour cream to boot. I was skeptical when I first heard the calorie-cutting measures, but upon first bite, decided that I’d probably need another slice.
