Step one. Bring water to a boil in a medium saucepan. Once bubbling, stir in packet of Jell-O mix, stirring until completely dissolved. Turn off heat. Pour in Fireball, mixing until thoroughly combined. Pour into a large measuring cup, small pitcher or another glass so it's easier to pour into the shot glasses.
Step 2, Pour the Jell-O mixture into each of the shot glasses. Place the shot glasses into the refrigerator until the Jell-o sets, about 2 hours.
And then, Dollop with Cool Whip then sprinkle Red Hots and sprinkles on top.
