I love mini cupcakes.
Instead of frosting them the old fashion way, get the wilton cupcake decorating set. It comes with a few tips and bags.
Go to you tube and type in cupcake swirl and it will show you how to do a classic swirl. With mini cupcakes you really don't even have to "swirl them" you can use the tip to dab out frosting, because the cake is so small.
It's not hard, I promise, you just need a few practices then usualy you have it.
I also second the idea of cake pops. Those are super easy (just as easy as cupcakes) and easy to store/travel with. Right now at all the craft stores they have the pastel colored candy melts too. To store them I get a cake box (party city, michales etc has them) and a styrofoam block.
Good luck!
