The light fluffy texture of this fantastic flourless yogurt cake is almost soufflé-like and the flavour is tangy and cheesecake-like. It's a decadent treat you can eat without feeling guilty - a lightened up cheesecake made without heavy cream cheese. Serve it just plain, sprinkled with a dusting of powdered sugar, or dress it up for company with billows of softly whipped cream and a pile of fresh berries.
