Whenever I need a chocolate fix, with a minimum of calories, I reach for Dr Oetker Mousse 50 Calories Milk Chocolate. It's light-as-air chocolatey goodness without all the guilt. At 50 calories per serving (or 250 calories for the whole box - yup, I eat the whole box), it's indulgent without wrecking the diet. Plus, you get calcium from the skim milk used to make it.
