Rim your shot glasses by adding a shallow layer of corn syrup to a saucer, and adding ground cinnamon and sugar to another saucer. Stir together the cinnamon and sugar slightly.
Dip each shot glass into the corn syrup, then into the cinnamon sugar mixture.
Add 1 oz. Fireball and 1 oz. RumChata to each shot glass (we used 2 oz. glasses, adjust for different size shot glasses- I.E. ½ oz and ½ oz, making 8 total).
