Whisk the instant chocolate pudding mix with cold milk in a bowl until smooth and slightly thickened, about 2 minutes. Place in the refrigerator to firm up for about 5 minutes.
Spoon or pipe the firm pudding into each jar, filling about halfway to create the base layer.
Sprinkle a generous layer of crushed cookies over the pudding to resemble dirt or soil, covering the pudding evenly.
Repeat the layering process by adding another layer of pudding, then a final layer of crushed cookies to build up the scene and give height.
Decorate the top with creepy candy bones, positioning them to mimic grave markers or spooky skeletons among the dirt.
Arrange additional candies, ghosts, gravestones, or decorative elements on the surface for extra spooky detail.
Refrigerate the cups for at least 15 minutes before serving to let the flavors meld and the scene set properly.
Serve these playful graveyard-themed pudding cups chilled, allowing everyone to enjoy the spooky scene and delicious flavors.
