Bright, tangy lemon meets cool, creamy goodness in this no-bake lemon icebox cake with cream cheese, graham crackers, lemon pudding, and whipped topping. It’s sunshine on a fork—ridiculously easy, dreamy and perfect for a crowd.
Beat the cream cheese in a large bowl with an electric mixer until smooth and creamy, scraping the sides as needed to avoid lumps.
Add instant lemon pudding mixes and cold milk. Beat for about 2 minutes until the mixture thickens and forms a smooth, scoopable filling.
Gently fold in the whipped topping using a spatula, just until blended and creamy. Don't overmix.
Arrange a single layer of graham crackers in the bottom of a 9x13 inch baking dish. Break crackers as needed to fit.
Spread about one third of the lemon-cream mixture over the crackers. Repeat the layers two more times, ending with the lemon mixture on top (for three total layers of each).
Cover the dish with plastic wrap and refrigerate for at least 4 hours (overnight is even better) to soften the graham crackers and set the cake.
Before serving, garnish with fresh lemon zest and thin lemon slices if desired. Slice and serve cold.
Notes
This cake can be made 1-2 days ahead and gets creamier as it sits. Store leftovers covered in the fridge for up to 4 days. Freezing is not recommended as it changes the texture. To substitute Cool Whip, use 3 cups stiffly whipped cream. Try a swirl of lemon curd between layers, or add fresh berries for variety.
