The blend of Key Lime Cream Rum, pineapple juice, and lime Jell-O creates an elevated yet simple party treat that’s creamy, bright, and crowd-pleasing.
What is a jello shot?
A jello shot is simply flavored gelatin mixed with alcohol and served in a small cup to enjoy as a shot.
Why these will be your favorite:
- We use fruit juice instead of plain water for better flavor.
- More flavored liquor for a bolder, creamier taste.
- Playful and delicious flavor combinations.
- Toppings—like Lucky Charms marshmallows and green sprinkles—finish them off perfectly.
- Serve alongside other festive options for variety.

How to make Key Lime Lucky Charms Jello Shots
Start by chilling the Key Lime Rum Cream in the freezer; very cold liquor helps the gelatin set properly.

Microwave equal parts pineapple juice and water until they begin to boil. Whisk in the lime Jell-O until fully dissolved, then stir in the chilled rum.
Pour the mixture into twenty-eight 2-ounce portion cups, filling each about three-quarters full. Chill for 30–45 minutes before adding one Lucky Charms marshmallow on top and a light dusting of green sprinkles.

Tips for the best jello shots
- Use very hot liquid to dissolve the Jell-O completely.
- Use very cold liquor to help the gelatin set.
- Avoid freezing jello shots; freezing can change the texture and flavor.
- Make them up to two days in advance and keep covered in the refrigerator.
How to take a jello shot
Loosen the jello from the cup with a fingertip, tip it into your mouth, and chew to enjoy the full flavor before swallowing. Cheers!
