GWG8541 I am not necessarily a big Dr. Pepper fan, but it has its place. If I am even doing soda I would prefer Coke most of the time, which is not much, very, very little. Otherwise, Buffalo Rock is my hands down favorite. It just has that kick that none of the others have any more & the right ingredients are there too. That would probably be too much for this recipe though, but I thought the Pepper would have that flavor twist to it that might do it right.
