Step 1

Combine the pudding mix with the milk and whisk to combine. Pour into a 13x9-inch baking dish and refrigerate for 30 minutes.

Step 2

While the pudding sets, place the chocolate sandwich cookies in a large zip-top bag and crush using a rolling pin.

Step 3

Top the pudding with the crushed cookies and place a Milano cookie every 2 inches, staggering their placement, to look like a graveyard. Add gummy worms or pumpkin candy corns, if using. Serve immediately or refrigerate for up to 2 hours.
