In a mixing bowl, combine the crushed chocolate sandwich cookies with the melted butter. Stir until evenly mixed, then press the mixture firmly into the bottom of a baking dish to create a crust.

Beat the softened cream cheese, powdered sugar, and vanilla extract together until smooth and creamy.

Gently fold half of the whipped topping into the cream cheese mixture until fully integrated.

Pour the cream cheese and whipped topping blend over the cooled cookie crust, spreading it evenly.

In a separate bowl, whisk together the chocolate pudding mix and cold milk until the mixture thickens.

Spread the thickened pudding over the cream cheese layer, smoothing it to the edges.

Add the remaining whipped topping over the pudding layer, smoothing it out.

Decorate the top with colorful holiday sprinkles and mini chocolate chips. Chill in the fridge for at least 4 hours.
