If you are doing the optional glass rim, pour caramel in a small dish and the graham cracker crumbs in a second small dish. First dip your shot glass rim in the caramel sauce, shaking off the excess. Then dip it into the crumbs.
In a cocktail shaker or jar with a secure lid, add the whiskey, apple cider, and caramel and shake to combine. Pour into the shot glasses.
