Place your mixing bowl and whisk attachment (or beaters) in the refrigerator for 10–15 minutes to chill. Cold tools help the pudding set up thick and smooth.
In the chilled bowl, whisk together the instant vanilla pudding mix and very cold milk for about 2 minutes, until thickened and the pudding slowly falls off the whisk.

Add the thawed whipped topping to the pudding. Gently fold it in with a spatula, turning the bowl and lifting from the bottom so you keep the mixture light and fluffy.

In a 9×13-inch baking dish, arrange a single layer of graham crackers to cover the bottom, breaking pieces as needed. Small gaps are fine.

Spoon half of the pudding mixture over the graham crackers and spread it evenly to the edges and corners.

Add a second layer of graham crackers over the pudding. Spread the remaining pudding mixture on top, then finish with a third layer of graham crackers as the top layer.

Place the chocolate chips in a medium heat-safe bowl. In a small saucepan over medium heat, warm the heavy cream until steaming and just starting to bubble around the edges (do not boil). Pour the hot cream over the chocolate chips and cover the bowl. Let sit for 3–4 minutes.
1 1/2 cups semi-sweet chocolate chips, 3/4 cup heavy cream
Add the butter, vanilla extract, and a pinch of fine sea salt to the bowl. Whisk until the chocolate is completely melted and the mixture is glossy and smooth. If small bits of chocolate remain, microwave for 10–15 seconds and whisk again.

Let the ganache rest at room temperature for 5–10 minutes, until slightly thickened but still pourable, so it clings to the top graham cracker layer.
1 1/2 cups semi-sweet chocolate chips, 3/4 cup heavy cream, 2 tablespoons unsalted butter, 1 teaspoon vanilla extract, 1 pinch fine sea salt
Slowly pour the ganache over the top layer of graham crackers. Use a spatula to spread it evenly to the edges, smoothing the surface.

Cover the pan lightly with plastic wrap, avoiding direct contact with the ganache, and refrigerate for at least 4 hours, preferably overnight, until the graham crackers have softened to a cake-like texture.
Run a thin knife around the edge of the pan. Cut into squares with a sharp knife, wiping the blade with a warm, damp cloth between cuts for neat slices. Garnish with shaved chocolate, crushed graham crumbs, or fresh berries if desired.
