Exclamation meaning

Question

I don't understand the significance of !Qué bárbaro! in the second paragraph. It seems out of place in relation to the description of the dessert, but I'm sure I don't fully understand its meaning. According to my dictionary, it translates to "how barbaric" --- but why would it be characterized in that manner?

It's used in this way as a slang term to mean "great" or "fantastic".
