How many calories are in a slice of cake?
A 95-gram slice of home-recipe chocolate cake is about 352 calories; as the slice gets smaller the figure drops to 150.
The American food database's home recipe chocolate cake record gives 371 calories per 100 grams and counts one slice, a twelfth of a nine-inch cake, as 95 grams; that comes to about 352 calories. If the slice drops to 40 grams it is 148, and if a bakery slice rises to 130 grams it comes close to 480 calories.
