If you have regular white table sugar, you can put that into a blender and run it through there three or four times until it gets to the powdery consistency. That's all that powdered sugar is, white sugar that has been chopped up until it's a powdery substance. I've done that in a pinch. It wouldn't be my prettiest cake, but it would still taste good, the only difference would be that it might be a little more 'grain-like'. When they powder the sugar, they run it through heavy crushing stone rollers (or similar) and any other way makes it a little more grainy.
