Umm...does it have to be healthy? This is an EASY one you can make for parties to fatten up everyone else.
Take 1 package of Oreos. One package of cream cheese. Mush both together till they turn into a kind of dough. Yes, a whole package of cookies, cream filling and all. Then, let it cool so it is easier to work with. Roll into balls, dunk in some melted chocolate chips and set on wax paper in the fridge to harden. If you want to be extra creative, drizzle with melted white chocolate. I've also added almond flavour or little crushed thin mint pieces. You could add coconut or put something in the middle like a bit of peanut butterish gnash (sp?). Wide range of possibilities, and the easiest truffles you'll ever make. Keep them small, they are rich.
