Rim a 4 oz. martini glass with cinnamon sugar (if you haven't done this before, wipe the rim of your glass with a little water or ginger ale, then dip the top edge in a little cinnamon sugar on a small plate).
Put some ice cubes in a shaker tin, and add your liquors. Shake until chilled and pour. Sprinkle a little cinnamon sugar on top, serve, and enjoy!
