The fried and filled dessert weighs in at 24 grams of sugar, 40 grams of total carbohydrates, 330 calories, and 18 grams of fat, according to Marilynn Marter of the Philadelphia Inquirer, who gives it a thumbs up: "This confection is as decadent as it is finger-lickin' good." The special donut is available through August. Photo: www.krispykreme.com.
