Creating Raspberry Chocolate Dessert Lasagna with Whipped Cream Layers is straightforward. Follow these detailed steps to make this incredible dessert:

1. Prepare the Crust: In a mixing bowl, combine chocolate cookie crumbs and melted butter. Stir until well mixed, then press the mixture firmly into the bottom of a 9×13 inch baking dish to create a crust.
2. Make the Cream Cheese Layer: In another bowl, beat the softened cream cheese until smooth. Gradually add powdered sugar and vanilla extract, mixing until well combined and creamy.
3. Whip the Cream: In a separate mixing bowl, whip the heavy cream until stiff peaks form. Gently fold half of the whipped cream into the cream cheese mixture until well blended.
4. Layer the Cream Cheese Mixture: Spread the cream cheese mixture over the prepared chocolate crust evenly.
5. Prepare the Chocolate Pudding: In a large mixing bowl, whisk together the chocolate pudding mix and milk until smooth. Allow it to sit for about 5 minutes to thicken.
6. Add the Pudding Layer: Pour the thickened chocolate pudding over the cream cheese layer, spreading it evenly.
7. Layer the Raspberries: Scatter the fresh raspberries evenly on top of the chocolate pudding layer.
8. Add More Whipped Cream: Fold the remaining whipped cream into a fluffy topping. Spread it gently over the raspberry layer until entirely covered.
9. Chill: Cover the dessert with plastic wrap and refrigerate for at least 4 hours, or ideally overnight, to set.
10. Garnish and Serve: Once set, garnish with additional fresh raspberries and chocolate shavings if desired.
