Cornstarch is added to confectioners (powdered) sugar to prevent the sugar from lumping, so the amount is quite minimal. And adding cornstarch to granulated sugar isn't what makes it confectioners sugar. Confectioners sugar is much finer and softer than granulated sugar, it has a texture much like that of cornstarch. So you would have to be able to grind granulated sugar into a very fine powder in order to make it like confectioners sugar.

Confectioners sugar it's milled to a much finer grain and, and it has cornstarch in it to prevent caking. If you run of of Granulated sugar, you can substitute with Confectioners sugar. Multiply the amount of granulated sugar needed by 1.75. It takes 1 3/4 cup of powdered sugar to substitute for 1 cup of granulated sugar.
