Pipe the letters "R.I.P." onto each cookie then allow letters to set and harden.
While the cookies rest, remove the lids of the pudding cups and discard. Stir cups with a spoon or spatula to even out the surface of the pudding.
Spoon 1 heaping Tablespoon of crushed Oreos evenly onto the surface of each pudding cup. If you want to make more than the 8 cups in the recipe, you will need 1 Oreo2 per cup. Feel free to add more crushed Oreos, if desired.
Place one R.I.P. cookie into each pudding cup, pushing it down gently until it is securely in place. If the chocolate isn't completely hardened yet, that's ok. Just be careful not to disturb the letters.
If using, add some green sprinkles to the dirt. You may also consider adding pumpkin mellowcremes, gummy worms, or gummy skulls. Pudding cups are best served immediately, as cookies start to get soggy quickly. If traveling to a party, prepare the cups as much or as little as you wish, but save the headstones for last and add them right before serving.
Oreos: 1 Oreo will give you approximately 1 Tablespoon of crushed Oreo crumbs. If you need more than this because the level of your pudding cups is lower than you'd like, aim for 12 Oreos per 8 pudding cups.
