Lay out 16 to 20 jello shot cups on a cookie sheet.
Combine the package of jello with 1 cup boiling water in a mixing bowl. Stir until all of the crystals have dissolved.
Mix in ½ cup malibu rum and ½ cup coconut milk.
Fill each of the jello shot cups about ¾ full with the mixture.
After the jello has cooled completely, put the lids on the cups.
Refrigerate for 2 to 4 hours or until the Jello has set.
Notes
Putting the jello shot cups on a cookie sheet makes it easier to transport them to the refrigerator and catches any spills that might occur. But it isn't absolutely necessary.
Depending on how strong you want the jello shots to be, adjust the amount of coconut milk and rum. Just make sure that the two combined come out to 1 cup.
If you put the lids on the jello shot cups before the jello has cooled, you will get condensation forming on the inside of the lids. This does not affect the taste of the jello shots but doesn't look as good.
