Made from dough leavened with yeast and rolled into a coil, honey buns are deep-fried then coated with a layer of sugary white icing. High in calories, honey buns contain significant amounts of both carbohydrates and fat.
The U.S. Department of Agriculture Nutrient Database indicates that one large honey bun, around 4.5-by-3.5 inches, weighs 78 g. Carbohydrates make up 40 g, while fats contribute 15 g, and proteins deliver 5 g. The remainder consists of indigestible matter, other nutrients and water.
The USDA also indicates that there are 311 calories in a large honey bun. Of these, carbohydrates provide 158 calories, fats deliver 134 calories and proteins contribute 19 calories.
