Betty Crocker lighter recipe Carrot cake?

ok, so my family made this healthy carrot cake. It says 300 calories/serving. But we didnt make it with the cream cheese frosting. So how many calories are per serving then?

Figure out the caloric content of the ingredients in the frosting, divide it by the number of servings and subtract that from the 300 calories per serving. That will tell you how much a serving without frosting contains.
