Sweet beer?

Hi everyone. I am looking for the sweetest beer that you can think of. I'm not a fan, but a friend of mine and I have a running joke about her putting sugar in her beer once (yes, I know. She will never stop hearing about it). Anyway, it's her birthday soon and thought a good gag gift to get her would be a very sweet beer. Any suggestions? I live in Buffalo NY for reference, but am willing to travel anywhere in the WNY area.
