Creating your No-Bake Christmas Cookie Lasagna is a simple process. Follow these steps for delicious results:

1. Prepare the Cookie Crust: In a food processor, crush the Oreo cookies until they are fine crumbs. Mix with melted butter until well combined. Press the mixture evenly into the bottom of a 9×13 inch baking dish to form the crust.

2. Make Cream Cheese Layer: In a large bowl, beat the softened cream cheese with a hand mixer until smooth. Add the powdered sugar and vanilla extract, mixing until creamy. Fold in 1 cup of the cool whip until well combined.

3. Spread Cream Cheese Mixture: Spread the cream cheese layer evenly over the Oreo crust in the baking dish.

4. Prepare Pudding Layer: In another bowl, whisk together the milk and instant vanilla pudding mix until smooth. Allow it to sit for about 2 minutes until it thickens.

5. Layer Pudding: Pour the pudding mixture over the cream cheese layer, spreading it out evenly.

6. Add Cool Whip Layer: Top the pudding layer with the remaining cool whip, spreading it to cover the entire surface.

7. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours, or ideally overnight, to allow the layers to set properly.

8. Garnish: Before serving, sprinkle crushed peppermint candies and additional crushed Oreo cookies on top for a festive touch.
