1. Prepare the Crust:

1. Crush the Oreo cookies into fine crumbs using a food processor or by placing them in a ziplock bag and crushing with a rolling pin.
2. In a large bowl, beat the softened butter, cream cheese, and powdered sugar until smooth and creamy.
3. In another bowl, whisk the chocolate pudding mix with cold milk until thickened, then fold in the whipped topping.
4. Combine the cream cheese mixture with the pudding mixture until well blended.
5. Layer half of the crushed Oreos in the bottom of a serving dish, followed by half of the pudding mixture. Repeat the layers.
6. Top with additional crushed Oreos and gummy worms if desired.
7. Refrigerate for at least 2 hours before serving.
