Which mutual funds can I invest in to guarantee 15%+ growth annually for the next 15 years?

none... no one can guarantee those results. if they say they do, run away.
If I knew that I'd be planning on my retirement in 15 years. If anyone ever tries to tell you they can guarantee that kind of growth, just walk away with no regrets. You've just talked to a swindler, and if you actually give that crook any money, I have some ocean front property on the moon that I'd like to sell you cheap.

None...in fact, I'd wager everything I've got that no mutual fund will gain at least 15% every year for the next 15 years. I took a quick look on Morningstar, and I couldn't find a fund that has posted 15% returns consecutively for longer than 7 years.
