For all cheesecake fans out there (myself included), I found a recipe that is far less worrisome (particularly for the health conscious) in the form of a Chilled Orange Yogurt Cake. Looks like a chilled cheesecake. Taste almost like a cheesecake (although the sour tang of yogurt is unmistakeable), but far less distress-causing in terms of calories than a normal cheesecake.
Recipe found here from Tazz In The Kitchen blog. Go on, try it!
ps: However, I would not recommend yogurt-haters to try this cake.
