Do I need a special recipe for mini cheesecakes?
A full-sized recipe should be fine for putting the mini-cakes together. The taste of your cheesecake will stay the same regardless of size, so long as your ingredients are mixed well and you don't overfill the cups of your pan. Marbling shouldn't be a problem either.

You may want to watch your cooking time. The cakes will be smaller, so it won't take as much time in the oven to cook all the way through. I'd set the timer for half the time that the original recipe calls for. If the mini-cheesecakes aren't done by then, monitor very closely for the next couple of minutes. It won't take much more time than that.
