1. Pulse the chocolate sandwich cookies in a food processor until finely crushed. Set aside.

2. In a medium bowl, whisk together the chocolate pudding mix and cold milk. Let it set for 5 minutes.

3. In a separate large bowl, beat softened cream cheese until smooth. Fold in the whipped topping until fully incorporated.

4. Add the set pudding to the cream cheese mixture and stir until well combined.

5. Begin layering in clear cups: start with crushed cookies, then a layer of pudding mixture. Repeat as desired.

6. In a microwave-safe bowl, melt chocolate chips and heavy cream in 30-second intervals until smooth. Stir well.

7. Spoon or pipe the ganache around the cup rims for a drip effect. Chill to set.

8. Pipe a swirl of remaining cream on top and decorate with gummy worms, cookie tombstones, and sprinkles.
