Step 1

Place oreos in a large ziplock bag and seal. Use a rolling pin to crush oreos. Pour melted butter in the bag and shake to combine.

Step 2

Whisk the milk and pudding mix together in a bowl until starting to thicken, about 2 minutes. Set aside.

Step 3

Place the cream cheese and sugar in the bowl of an electric mixer. Beat on medium high speed until the mixture is smooth and no lumps remain.

Step 4

Fold the pudding in, beating on low speed until well combined. Stir in whipped topping.

Step 5

If you're using a large play pail to serve the pudding, you might want to place the whipped topping lid upside down in the bottom. This shortens the pail and makes it so the pudding will go all the way up to the top. Place a layer of Oreos at the bottom. Put a layer of the pudding mixture over top. Repeat until both are gone, beginning and ending with the Oreos. Arrange gummy worms on top. Refrigerate for at least 3 hours or overnight.
