Ingredients

• 14.4 oz graham crackers
• 3 cups cold whole milk
• 6.8 oz (2 boxes) instant lemon pudding mix
• 8 oz whipped topping (thawed)
• 32 oz premade lemon frosting
• 15 lemon slices (optional)
• Fresh mint leaves (optional)

Instructions

1. Prepare a 9×13-inch baking dish by lightly coating it with nonstick spray to prevent sticking.
2. Arrange a single layer of whole graham crackers across the bottom of the baking dish. Break pieces if needed to fully cover the surface.
3. In a large mixing bowl, pour in the cold milk. Add both packages of instant lemon pudding mix. Using a hand mixer, beat the mixture on medium speed for about 1½ to 2 minutes until it thickens to a smooth pudding consistency.
4. Gently fold the whipped topping into the pudding mixture using a spatula. Continue folding until fully combined and creamy.
5. Spoon half of the pudding mixture over the graham cracker layer. Spread it evenly using an offset spatula to create a smooth surface.
6. Add a second layer of graham crackers directly on top of the pudding layer.
7. Spread the remaining pudding mixture evenly over this second cracker layer.
8. Finish with a final layer of graham crackers on top.
9. Remove lids and seals from the lemon frosting containers. Microwave for about 45 seconds until softened and pourable. Stir until smooth.
10. Pour the melted frosting over the top layer and spread evenly with a spatula to fully cover.
11. Place the dish in the refrigerator and allow it to chill for at least 8 hours or overnight so the layers soften and set.
12. When ready to serve, slice into squares. Garnish each piece with a lemon slice and mint leaves if desired.
