“Too many” kinda sounds right to my ear because beans is plural, but the second logically seems right because its served by volume and is not ‘countable’ as ordinary (non-destroyed) beans might be.

You would say “too much mash potato” rather than “too many mash potatoes”, and the consistency is similar
Difference is with “refried beans” the countable noun is plural (“refried beanS” vs “mash potato”).
Saying “too much refried bean” sounds a bit more natural.
This is literally the first time I’ve ever heard mashed potato be singular. My phone even tried to make it plural.
Probably one of those regional variations that would look interesting overlaid on a map…
I would have said “mashed potato” for your first example.
