Could you explain with more details what you are trying to achieve?
Sending all the queries you're receiving from the Recursor to an Authoritative
server wont' work, as the Auth will only answer for the DNS zones it is Auth
for.

Google Public DNS is not an Authoritative service, but a recursive one.

Also, forward-zones-recurse means you are sending requests to a recursive DNS
server (https://doc.powerdns.com/recursor/settings.html#forward-zones-recurse),
which your PDNS Authoritative is not - hence the fact that this second method
doesn't work.

Cheers,
