Mix the 4 tablespoons of milk with the peanut butter (mixture will be thick).
Stir in container of cool whip.
In a separate bowl, whisk 11 oz.
of milk with the pudding for 2 min.
(mixture will be thicker than regular pudding).
Fold the cool whip mixture into the pudding.
Spoon mixture into shortbread crust.
Garnish with chopped chocolate and peanuts (I like to use just a little bit for a garnish and let individuals add more on their plate if they want it).
