Cookies, chocolate pudding, and Cool Whip are layered and frozen for 4 hours to make this easy no-bake dessert.
Crush chocolate sandwich cookies. Mix in butter. Press mixture into a 9x13-inch baking pan to make the crust. Refrigerate crust.
Beat cream cheese until fluffy. Add sugar and 2 tablespoons milk; mix well. Stir in 1 1/4 cup whipped topping. Spread mixture onto the crust and refrigerate.
Mix pudding with 3 1/4 cups milk until thickened, about 5 minutes. Spread over the cream cheese layer. Refrigerate lasagna for 10 minutes.
Spread remaining whipped topping over the lasagna and sprinkle with chocolate chips. Refrigerate for 4 hours.
