In a medium bowl, combine 8 ounces of softened cream cheese and 1 cup of powdered sugar. Use a hand mixer on medium speed for about 2-3 minutes, or until the mixture is smooth and creamy, with no lumps remaining.

Gently fold in 2 cups of whipped topping into the cream cheese mixture using a spatula. Be careful not to over-mix.

In a separate bowl, combine a 3.4-ounce package of instant pudding mix (chocolate or vanilla) with 2 cups of cold milk, whisk for about 2 minutes until the pudding thickens.

In a trifle dish or large bowl, layer half of the crushed Oreos evenly as the base.

Spoon half of the cream cheese mixture over the Oreos, spreading it evenly. Follow with half of the pudding.

Next, repeat the layers by adding the remaining crushed Oreos, followed by the rest of the cream cheese mixture, then top with the leftover pudding.

Finish off by spreading the remaining 2 cups of whipped topping over the final layer of pudding.

Decorate with Halloween candy on top of the whipped topping.

Cover with plastic wrap and place it in the refrigerator for at least 4 hours, or ideally overnight.
