Do you want more?
Are “mera” and “mer” interchangeable in this context?
Is “Vill du ha mer?” also correct?
Yes, in this context they are interchangeable. Usually it’s only in some set phrases (for example “med mera” “mer och mer”) that they can’t be switched.
I personally prefer to use “vill du ha mer?”
FWIW, if you search the corpus you will find a lot more sentences using “mer” than “mera”.
