When using this frosting, I like to decorate with halves of actual Oreo cookies. I have found that when I cut an Oreo in half, I end up with one that looks great and the other is a mess. So if that is your plan, make your Oreo halves first, and use the messed up halves to crush up and add to the frosting.
