Spray a 9x13 baking dish lightly with nonstick cooking spray. Set aside.
Lemon Cookie Crust : In a food processor, crush the lemon sandwich cookies until well crumbled and in fine pieces. Add in the melted butter, and pulse a few times to form a mixture that resembles wet sand. Firmly and tightly press the cookie crust into the bottom of the prepared baking pan to form a crust.
32 lemon sandwich cookies, 1/2 cup (1 stick) butter
Cheesecake Layer : In a medium bowl, using an electric hand mixer, beat the cream cheese and granulated sugar until creamy and well combined. Add in the sour cream and mix until smooth. Gently fold in 2 cups of Cool Whip and mix until it's incorporated. Evenly spread this over the cookie crust to form an even layer. * Please note : Only use 2 cups of the Cool Whip (from the 16 ounce tub) in this cheesecake layer. The remaining Cool Whip will make the final top layer of the lush. 1 bar (8 oz) cream cheese, 1/3 cup granulated sugar, 1/2 cup sour cream, 1 container (16 oz) Cool Whip
Lemon Pie & Pudding Layer : In a separate mixing bowl, whisk together the lemon pie filling, heavy cream, and lemon juice until combined. Stir in the vanilla instant pudding mix until the mixture has thickened and everything is combined. Spread the lemon layer over top the cheesecake layer.
1 can (21 oz) lemon pie filling, 1 cup heavy cream, 1/4 cup freshly squeezed lemon juice, 2½ tablespoons vanilla instant pudding mix
Whipped Cream Layer : Stir together the remaining Cool Whip and vanilla instant pudding mix until it's well combined. This will form a slightly thicker Cool Whip mixture for the top layer. Spread it evenly over top the layered dessert for the final layer.

Cover & Chill : Cover the dessert with a lid or plastic wrap, and refrigerate for at least 6 hours or up to overnight is even better.
Serve : When ready to serve, serve the dessert chilled from the fridge and garnish the top with lemon zest and/or lemon cookie crumbles.
