Chocolate Texture

I'm creating a website for my Aunt's chocolate business and I'm in the brainstorming process. For the title I'd like to create a style similar to a Krackel Bar (sp?) on the text but I'm having trouble getting started. Am I asking for the impossible? Most texture tutorials begin with the difference clouds, but that doesn't seem to be working for this.

hrm...
buy a king size bar, and take a pic then get the path for the letters or whatever style u making it in...and just take it off of the bar. like w/ the text effect tutorials (lightning text or something)
i really don't know how to help u but ...this just popped in my head

have a look here could be of some help:
