I found these pudding shots on the TOH board. I've made this many different times and I'm not allowed to attend the annual family reunion weekend without bringing these. I've switched out the irish cream liquor and used raspberry schnapps and cheesecake pudding, lemon schnapps and lemon pudding, rootbeer schnapps and vanilla pudding, plus many other combos. Any flavor combination that you can find a complimentary liquor for will work.
