Whisk Creamer & Instant Pudding together until as thick as it will get (1-2 minutes).
Once it has thickened, add Liquor and whisk until smooth.
Once the mixture is nice and smooth again, whisk in Cool Whip.
Fill almost ¾ of a 1oz plastic shot cup with the mixture then cover & place in the freezer. For BEST results let them set overnight.
