Is it possible to make your own DIY cookie mix? Is it possible to create DIY mixes for cookies? I make chocolate chip cookies often enough to want to streamline the process. My idea is to create my own combine the dry ingredients, storing them in a box/tupperware of some kind, and then combining it with the wet ingredients when its time to bake.

My hypothesis is that it -should- be possible with pretty much any cookie recipe, but I thought it best to ask.
Freezing the portioned dough is more effective as a timesaver if you make a lot of dough but only a few cookies at a time. And as Catija notes, if you need to cream the butter and sugar a complete dry mix would not be practical.
