Put contents of instant pudding and powdered milk (should be enough powered milk to make 2 quarts) into a baggie.
Crush cookies and put in baggie.
Make pudding by whisking 7 cups treated water (not 8!) with pudding mix and milk powder. If it¹s too thick, add a little more water. Place crumbled cookie crumbs in bottom of rectangular pan and cover with pudding. Let
sit. OR simply spoon cookie crumbs on top of individual servings of pudding.
