You can find doughnuts in different shapes, sizes and varieties, and the calorie content of a doughnut varies. Cake doughnuts contain about 198 calories if they are of medium size. According to the U.S. Department of Agriculture, a glazed doughnut contains about 240 calories and 120 of those calories are from fat. A medium-size frosted cake doughnut has 251 calories, but if the doughnut is large, it can contain 327 calories.
Calories per Hole. Cake doughnut fans should be aware that each unglazed cake-style doughnut hole has 59 calories, 3.3 grams of fat and 2.3 grams of sugars. A glazed, yeast-leavened doughnut isn't much better with 55 calories, 3 grams of fat and 3 grams of sugar. Glazed chocolate cake doughnut holes will be similar in calories, but the jelly-filled doughnut holes are slightly higher in calories than unfilled doughnut holes.
