Whisk Creamer and Instant Pudding together until as thick as it will get (1-2 minutes).
Once it has thickened, add Liquor and whisk until all lumps and clumps are gone.
Stir or whisk in Chili Powder.
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 and place in the freezer.
It does take several hours to set. For BEST results, I let them set overnight.
