Place Fireball Cinnamon Whiskey and apple cider in a medium-sized liquid measuring cup with a pour spout and stir together.
Slowly pour mixture into popsicle molds just until reaching 1/4-inch below fill line. Next slowly pour a little Cherry Grenadine Syrup up to fill line of popsicle mold (this will give nice red effect to popsicle).
Place popsicle molds into freezer and let freeze for approximately 2 hours or until mixture starts to solidify enough to hold a popsicle stick upright.
Remove popsicle molds from freezer and check to see if liquid has started to solidify. As another option, cover popsicle molds with aluminum foil and cut slits to insert popsicle sticks immediately after pouring mixture into molds.
Insert popsicle sticks and then return popsicle molds to freezer and let freeze at least 8 hours to overnight until popsicles are frozen solid. Popsicles require longer freezing time with alcohol mixed in.
To help release popsicles from molds, run hot water on outside of popsicle molds for a few seconds.
Makes 5 to 6 Cocktail Popsicles.
* Can substitute another brand of cinnamon whiskey if desired.
