“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.

It depends on whether you’re referring to individual refried beans or the dish ‘refried beans’ as a whole.
If it’s the former, it would be ‘too many’ (individual) refried beans.
If it is the latter, it would be ‘too much’ (of) refried beans… Unless you had multiple servings, in which case it would be ‘too many’ (servings of) refried beans.
That is my opinion: as such it is subject to change should further information come to light.
