Here's two!

You could pick up some of those neat chinese food take-out containers-you know the ones-they're boxes and some have a litle metal handle on the top. I know they come in various sizes and you can buy holiday printed ones-I have seen them at dollar stores.

Your oreo balls would look a little like chinese chicken balls this way!

You could also buy those cute cellophane bags, clear or patterned, fill 'em up and add a decorative label(sticker or attached with ribbon) detailing the item name and ingredients(in case it has something in it that may cause allergies).
