Lightly grease a 9x13-inch baking dish with a thin layer of butter or nonstick spray. A glass dish works well to show off the layers.
In a medium bowl, combine the graham cracker crumbs, granulated sugar, and fine sea salt. Pour in the melted butter and mix with a fork until the crumbs are evenly moistened and resemble wet sand.
2 cups graham cracker crumbs, 1/2 cup unsalted butter, 1/4 cup granulated sugar, 1/4 teaspoon fine sea salt
Transfer the crumb mixture to the prepared baking dish. Press the crumbs firmly and evenly into the bottom of the pan, using the bottom of a measuring cup or flat glass to pack them down well. Place the crust in the refrigerator to chill while you prepare the filling (about 10–15 minutes).

In a large mixing bowl, beat the softened cream cheese with an electric mixer on medium speed until smooth and creamy, 2–3 minutes, scraping down the sides of the bowl as needed so no lumps remain.

Add the powdered sugar and vanilla extract to the cream cheese. Beat on low at first to avoid a sugar cloud, then increase to medium speed and mix until fully combined and smooth.
16 oz cream cheese, 1 cup powdered sugar, 1 teaspoon pure vanilla extract
Gently fold the thawed whipped topping into the cream cheese mixture using a spatula. Do not beat; folding helps keep the filling light and fluffy.

Remove the chilled crust from the refrigerator. Dollop the cream cheese mixture over the crust in several large spoonfuls to avoid disturbing the crumbs, then gently spread it into an even layer from edge to edge.

Open the cans of cherry pie filling and gently stir each one to break up any clumps. Spoon the cherry pie filling over the cream cheese layer in small portions, starting around the edges and working toward the center, then carefully spread into an even layer.

Cover the dish tightly with plastic wrap or foil and refrigerate for at least 4 hours, or overnight for the cleanest slices. This chilling time allows the layers to firm up and the flavors to meld.
When ready to serve, use a sharp knife to cut the dessert into squares. Wipe the knife clean between cuts for the neatest slices. Lift pieces out with a flat spatula and serve chilled. Optionally garnish with a dollop of whipped cream and a sprinkle of extra graham cracker crumbs.
