You could put her in a Vanguard target date retirement fund: https://personal.vanguard.com/us/funds/ ... rgetAnchor
I would probably just put the money in the 2050, 2055, or 2060 fund and call it a day. All of these choices are quite aggressive (approximately 90% stocks), but they will get more conservative (add more bonds) as your daughter gets older.
EDIT: I noticed you mentioned your daughter has no interest in investing. I would sit down with her and let her pick one of the aforementioned target retirement date funds, after giving her some information about each. Even if she's not interested in investing, it is still useful information to know how investing works (e.g. stock/bond allocation, becoming more conservative as you get older, how target date funds work, etc.).
