I don’t recommend freezing baked Cheese Twists. They become rather soggy in the freezer, and considering they are so quick and easy to make I find it’s best to just prepare them fresh each time.  You could freeze the unbaked twists if you wanted. My advice would be to place the baking sheets full of twists into the freezer for about 30 minutes - 1 hour until frozen, then transfer to airtight containers or freezer bags to store for up to 2 months. To bake, just place them back onto baking sheets and bake as directed.
