Caramel can be a terrible pain once it dries and sticks to something. The best way to deal with the extra caramel is to dump it out of the bowl while it is still warm.  Dump it into a heat proof bag or disposable container right away, then use hot water and soap to clean off whatever caramel is left. If you let it cool, you will have to reheat it in the microwave to get the rest of it off your bowls.
