Pass each find result as an argument with prefix to exec

I would like to find some files and turn them into a chain of arguments for a command. What I have so far is:

find . -name '*.yml' -exec cmd -f {} +

which results in

cmd -f ./foo.yml ./bar.yml

but what I really like to have is

cmd -f ./foo.yml -f ./bar.yml

(note the 2nd -f). How can I achive this?
