How many calories in a chocolate bar or cake?

To tell you how many calories are in a chocolate bar or cake, I need to know:

* What kind of chocolate bar? Is it a Hershey's bar, a Snickers, a dark chocolate bar, or something else? Each brand and type has different ingredients and calorie content.

* What kind of cake? Is it a chocolate cake, a vanilla cake, a cheesecake, or something else? The ingredients and size of the cake will affect the calorie count.

* What size? Is it a full-sized chocolate bar, a mini bar, a slice of cake, or a whole cake?

Once you give me these details, I can look up the nutritional information and tell you how many calories are in it!
