Ingredients

Scale

Base

  • 1 (14.4-oz) box graham crackers

Pudding Filling

  • 2 (3.4-oz) boxes instant lemon pudding mix
  • 3½ cups milk
  • 1 (8-oz) container Cool Whip, thawed

Topping

  • 1 (16-oz) can lemon frosting

Instructions

  1. Prepare Pan: Spray the bottom of a 9×13-inch pan with cooking spray to prevent sticking and make cleanup easier.
  2. Layer Graham Crackers: Line the bottom of the pan with one-third of the whole graham crackers, creating an even base layer.
  3. Mix Pudding: In the bowl of an electric mixer, combine the instant lemon pudding mixes with 3½ cups of milk. Beat at medium speed for 2 minutes until thickened. Gently fold in the thawed Cool Whip to create a light, creamy filling.
  4. First Pudding Layer: Pour half of the pudding mixture over the graham cracker base and spread evenly.
  5. Second Graham Layer: Add another layer of whole graham crackers on top of the pudding layer.
  6. Second Pudding Layer: Pour the remaining pudding mixture over the second graham cracker layer and smooth it out.
  7. Top Graham Crackers: Cover with the last third of whole graham crackers to form the final layer of the cake.
  8. Heat Frosting: Heat the lemon frosting uncovered in the microwave for 30 to 40 seconds until pourable but not hot.
  9. Add Frosting: Pour the warmed lemon frosting evenly over the top graham cracker layer to seal and flavor the cake.
  10. Chill: Refrigerate the assembled cake for at least 12 hours to allow the layers to soften and flavors to meld before serving.

Notes

  • Make sure to fully thaw the Cool Whip before folding it into the pudding mixture for best texture.
  • Heating the frosting makes it easier to spread and creates a smooth topping.
  • Allowing the cake to chill overnight is essential for the graham crackers to soften and the flavors to blend well.
  • You can substitute vanilla pudding and vanilla frosting for a different flavor.
  • Store leftovers covered in the refrigerator for up to 3 days.
