First title that came to mind is the first book of the Harry Potter series. Great voice talent, in Peninsular Spanish... (Ediciones Salamandra)
Alfaguara Audio has titles like "Como Agua para Chocolate" and many other titles... although these are in cassettes... (an obsolete medium... but I still have several of these...)
Alfaguara Audio has also titles in CD, by Mario Benedetti... but I don't know if there are other formats (MP3, MP4 or whatever...)
You can also search "cuentos infantiles en español" and see what you come up...
