Equipment

  • 9x13-inch Baking Dish
  • Mixing Bowls
  • Offset Spatula

Ingredients
  

Pudding Layer

  • 2 boxes instant lemon pudding mix 3.4 oz each
  • 3 cups cold milk
  • 1 container whipped topping 8 oz, thawed
  • 1 tbsp lemon zest approximately 1 lemon
  • 1 tbsp fresh lemon juice

Layers and Topping

  • 3 sleeves graham crackers approximately 27 crackers
  • 1 container prepared lemon frosting 16 oz

Optional Garnish

  • lemon slices
  • fresh berries
  • mint leaves

Instructions
 

  • In a large bowl, whisk together the instant lemon pudding mix and cold milk for 2 minutes until it begins to thicken. Allow it to set for 5 minutes.
  • Gently fold in half of the whipped topping until well combined.
  • Stir the fresh lemon zest and lemon juice into the pudding mixture to enhance the flavor.
  • Lightly coat a 9x13 inch baking dish with cooking spray or line with parchment paper for easy removal.
  • Arrange graham crackers in a single layer on the bottom of the prepared dish, breaking pieces as needed to cover the entire surface.
  • Spread half of the lemon pudding mixture evenly over the graham crackers using an offset spatula.
  • Add another layer of graham crackers, followed by the remaining pudding mixture, and top with a final layer of graham crackers. Press down gently.
  • Microwave the lemon frosting for 15-20 seconds until just softened but not melted. Quickly spread it over the top layer of graham crackers in an even layer.
  • Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight.
  • Before serving, allow the cake to sit at room temperature for 10-15 minutes for cleaner slices. Garnish with optional lemon slices, fresh berries, or mint leaves if desired.

Notes

For best results, ensure your milk is very cold—this helps the pudding set properly.
This dessert benefits from being made 12-24 hours in advance, giving flavors time to meld.
The cake stays fresh for up to 5 days when stored in the refrigerator.
Avoid freezing as it can affect the consistency of the pudding layers and cause graham crackers to become soggy when thawed.
