Instructions

1. Make the Filling

1. In a large bowl, whisk together the pudding mix and cold milk for about 2 minutes until it begins to thicken.
2. Let stand for 5 minutes.
3. Fold in the whipped topping and vanilla until smooth and fluffy.

2. Assemble the Cake

1. Lightly grease a 9×13-inch baking dish.
2. Arrange a single layer of graham crackers over the bottom, breaking crackers as needed to fit.
3. Spread half of the pudding mixture evenly over the crackers.
4. Add another layer of graham crackers.
5. Spread the remaining pudding mixture evenly over the second layer.
6. Finish with a final layer of graham crackers.

3. Make the Chocolate Frosting

1. Melt the butter in a saucepan over medium heat.
2. Whisk in the cocoa powder and milk until smooth.
3. Remove from the heat and gradually whisk in the powdered sugar, vanilla, and salt until glossy.
4. Let the frosting cool for about 10 minutes, then spread it evenly over the top layer of graham crackers.

4. Chill

• Cover the dish with plastic wrap or foil.
• Refrigerate for at least 8 hours, preferably overnight, so the graham crackers soften into a cake-like texture.
