First, preheat your oven to 350 degrees. This is crucial as it ensures that your crust bakes evenly, achieving that perfect golden-brown color.
In a medium bowl, stir together 2 cups of all-purpose flour, 1 cup of softened butter, 1/2 cup of finely chopped pecans, and 1/4 cup of sugar. Mix until everything is evenly combined and the mixture resembles coarse crumbs. This creates the base for your Lemon Lush.
Now, press the flour mixture into the bottom of a 9X13-inch baking pan. Make sure it’s evenly distributed and compacted for a stable crust. Bake this in the preheated oven for 20 to 25 minutes, or until it turns a lovely golden brown. Keep an eye on it to avoid over-baking, which can make it too hard.
Once baked, remove the crust from the oven and let it cool completely. This step is essential; a warm crust can melt the layers that will follow.
While the crust cools, take another bowl and beat together 2 packages of softened cream cheese, 1 cup of sugar, and 1 tablespoon of fresh lemon juice using a hand-held electric mixer. Beat until it’s smooth and creamy. This layer is rich and adds a lovely tang.
Spread the cream cheese mixture evenly over the cooled shortbread crust, ensuring every bite has that luscious creaminess.
Next, in a separate medium bowl, whisk together 2 packages of instant lemon pudding mix and 3 1/2 cups of milk. Keep stirring until the mixture thickens slightly, which should take about 3 to 5 minutes. This thickening is key to achieving that dreamy consistency.
Once thickened, pour this pudding layer over the cream cheese layer, spreading it evenly. This adds another dimension of flavor and texture to your Lemon Lush.
Now, refrigerate the assembled layers until they are completely set, which typically takes about 1 hour. This chilling time allows the layers to meld beautifully.
Finally, once set, spread the whipped topping over the top. This light, airy layer finishes off your dessert perfectly. Cut into squares and serve chilled. Enjoy!
