Mix butter, cream cheese and sugar and vanilla together. Set aside.
Combine milk and pudding mix. Mix Cool Whip into the pudding.
Mix together pudding mixture and butter-cream cheese mixture.
Layer this mixture(about 1/3 of it) onto the crumbled cookies in the container. Next, add another layer of the pudding mixture, then another layer of cookie crumbs, continuing until all ingredients are used.
As you're layering the ingredients, place several gummy worms through the mixture so they will be seen emerging.
Chill in fridge for 3-4hours and enjoy!
