2 (14.4 oz) boxes honey graham crackers
2 (3.4 oz) boxes instant French vanilla pudding mix
3 cups whole milk, cold
1 (8 oz) tub whipped topping (like Cool Whip), thawed
1 (16 oz) tub store-bought milk chocolate frosting
Mix the Pudding: In a large bowl, whisk together the instant French vanilla pudding mix and the cold milk for about 2 minutes, until it begins to thicken.
Fold in Whipped Topping: Using a rubber spatula, gently fold the thawed whipped topping into the pudding mixture until completely combined and smooth.
First Layer: Line the bottom of a 9×13-inch baking dish with a single layer of graham crackers, breaking pieces to fit the gaps if necessary.
Add Filling: Spread exactly half of the pudding mixture evenly over the graham crackers.
Second Layer: Add a second layer of graham crackers, followed by the remaining pudding mixture.
Top Layer: Place a third and final layer of graham crackers evenly over the pudding.
Melt Frosting: Remove the foil seal from the tub of chocolate frosting. Microwave for 15-20 seconds. Stir until the frosting is smooth and pourable.
Pour and Chill: Pour the melted chocolate frosting evenly over the top layer of graham crackers. Tilt the pan to spread it to the edges. Cover tightly with plastic wrap and chill in the refrigerator for at least 8 hours, or overnight.
Make-Ahead: This cake tastes significantly better on day two! Make it a full 24 hours in advance for the best, cake-like texture.
