Mix the crushed chocolate sandwich cookies with melted butter in a bowl. Stir until well combined and press the mixture firmly into the bottom of a baking dish to create a sturdy crust.

Beat together softened cream cheese, powdered sugar, and vanilla extract using an electric mixer until creamy and smooth. Make sure there are no lumps for a velvety texture.

Fold in half of the whipped topping gently with a spatula until just combined. Spread this fluffy mixture evenly over the cookie crust to form the first delicious layer.

Whisk the instant chocolate pudding mix with cold milk in a separate bowl until it thickens, about 2 minutes. The pudding should be creamy but thick enough to hold its shape.

Spread the rich chocolate pudding over the cream cheese layer evenly, giving a delightful contrast of flavors and textures with every scoop.

Top with the remaining whipped topping, smoothing it out to create a beautiful final layer. This will add a lightness that complements the denser layers beneath.

Decorate with holiday sprinkles and mini chocolate chips for extra flair. This step adds not only visual appeal but a delightful texture as well.

Chill the entire dish in the refrigerator for at least 4 hours before serving, allowing the layers to set perfectly and meld flavors together.
