Here you go! This is a great site. It has just thousands of recipes. If the one I gave the link to is not what you are looking for, then just go to the beverage heading, then alcoholic, then do a search for jello and you will come up with lots of different versions. Enjoy!
Here is a link that might be useful: Jello Shooters
I have a really easy good recipe that comes out more like a jell-o jigglers so you can make it in a pan and cut into squares instead of having to use little cups: 1 box jell-o
1 packet Knox
1 c. alcohol (I use mostly vodka and maybe some Chambord or Apple Pucker depending on jell-o flavour)
Water
Make Jell-o as per the recipe, substituting 1 c. alcohol for 1 c. of cold water. (don't forget the Knox).
Very easy and always a hit.
