                                The calorie count for a single slice of cake can vary dramatically, ranging from as low as 120 calories for a light angel food cake to well over 500 for a decadent, frosted variety. This wide range shows why it's so difficult to pinpoint exactly how many calories does an average piece of cake have without considering specific details.
