I have found that the standard frozen pie crusts that you bake in the oven work pretty well. Be a bit careful not to prick the crust too much with a fork before baking or it will break up on you. As for filling, I have only been able to do it with cool whip and shaving cream. Though I would love to be able to put cake mix or pudding in the bases, I find it is too heavy and the crust breaks apart. Good luck!
