Step 1: Prepare the Crust: In a medium bowl, combine the crushed Oreo cookies and melted butter. Press the mixture firmly into the bottom of a 9×13 inch baking dish. Place in the freezer to chill while you prepare the next layer.
Step 2: Make the Cream Cheese Layer: In a large bowl, using an electric mixer, beat the softened cream cheese until smooth and creamy. Gradually add the powdered sugar and continue beating until light and fluffy. Gently fold in half of the thawed whipped topping until no streaks remain.
Step 3: Spread Cream Cheese Layer: Carefully spread the cream cheese mixture evenly over the chilled Oreo crust. Return the dish to the freezer or refrigerator to set while you prepare the pudding layer.
Step 4: Prepare the Pudding Layer: In another large bowl, whisk together the instant vanilla pudding mixes and cold milk for about 2 minutes, or until the mixture begins to thicken. Stir in the vanilla extract.
Step 5: Layer the Pudding: Pour the thickened pudding mixture gently over the cream cheese layer, spreading it evenly with a spatula.
Step 6: Top with Whipped Topping: Spread the remaining half of the thawed whipped topping over the pudding layer, creating a smooth, inviting top.
Step 7: Chill and Serve: Cover the dish loosely with plastic wrap and refrigerate for at least 4 hours, or preferably overnight, to allow the heaven on earth cake no bake recipe to set completely. Garnish with chocolate shavings or fresh berries before serving, if desired.
