Peanut butter and chocolate -- the perfect flavor combination. These biscotti are bit more time- and energy-intensive to make than a basic cookie, but at a five-dozen yield, they are certainly worth the effort. Package them up into decorative tins to give away as gifts or set them out on a platter at a party. Each piece is 105 calories and just under 6 grams of fat, so going back for seconds won't blow your dessert calorie budget.
