Now, carefully fold the prepared vanilla pudding into the cream cheese and whipped topping mixture. Mix until just combined and smooth. This creates your luscious, creamy filling.
Assemble the Layers: Carefully spread half of the creamy filling evenly over the pressed cookie crumb base in the baking dish.
Sprinkle half of the reserved cookie crumbs over the first layer of cream.
Spread the remaining half of the creamy filling over the cookie crumbs, creating your second creamy layer.
Finally, sprinkle the last of the reserved cookie crumbs over the top of the second creamy layer.
Prepare the Chocolate Topping: Open the can of chocolate frosting and transfer it to a microwave-safe bowl. Add 2 tablespoons of whole milk to the frosting.
Microwave the frosting and milk on high for 30-60 seconds, stirring every 15 seconds, until the frosting is melted and smooth enough to pour or spread easily. Be careful not to overheat it.
