Ingredients

Scale

Base

  • 1 (14.4-oz) box graham crackers

Pudding Layer

  • 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 the 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 the first crust layer.
  3. Make the Pudding Mixture: In the bowl of an electric mixer, combine the instant lemon pudding mixes with the milk. Beat at medium speed for 2 minutes until it thickens. Gently fold in the thawed Cool Whip to create a creamy texture.
  4. Add First Pudding Layer: Pour half of the pudding mixture evenly over the graham cracker layer to create a smooth filling.
  5. Second Graham Cracker Layer and Pudding: Place another layer of whole graham crackers on top of the pudding. Then pour the remaining pudding mixture over it, spreading evenly. Top with the last third of graham crackers to complete the layers.
  6. Top with Frosting: Heat the lemon frosting uncovered in the microwave for 30 to 40 seconds until it’s pourable. Pour the warmed frosting evenly over the top layer of graham crackers.
  7. Chill: Refrigerate the assembled cake for at least 12 hours to allow the layers to set and the flavors to meld, resulting in a soft, eclair-like texture.

Notes

  • For best results, use full-fat milk and Cool Whip to achieve the richest creaminess.
  • Make sure to thaw the Cool Whip fully before folding it into the pudding mixture.
  • The 12-hour refrigeration is essential to allow the graham crackers to soften and the cake to set properly.
  • If you prefer, you can add a sprinkle of powdered sugar or fresh lemon zest on top before serving for extra flavor and presentation.
  • This dessert can be assembled a day ahead, making it convenient for parties or gatherings.
