Diabetic Cafe Au Lait Pudding

Follow the directions on the package for preparing the vanilla pudding: add 2 cups of cold milk and pudding mix in a bowl and whisk for two minutes.
In a separate bowl, prepare the chocolate pudding.
The directions call for 2 cups of milk. Instead, put in 1½ cups of milk and ½ cup of chilled coffee and pudding mix in a bowl and whisk for two minutes.
Transfer about 4 tablespoons of the vanilla and 4 tablespoons of the chocolate pudding to a third bowl.
Add 2 more tablespoons of coffee to this batch.
Whisk this batch.
It should appear a few shades lighter than the chocolate pudding's color.
Discard the remainder of the coffee (or drink it).
Layer in cups or parfait glasses. Refrigerate for five minutes. Garnish with whipped cream and or a sprinkling of coco, if desired, before serving.
