This Easy Lemon Icebox Pie is a creamy, no-bake frozen dessert made with a buttery graham cracker crust, a silky-smooth lemon filling of fresh lemon juice, cream cheese, and sweetened condensed milk, and a fluffy whipped cream topping. Bright, tangy, and refreshingly cool, it comes together in just 15 minutes and is the ultimate make-ahead summer dessert that always disappears fast.

Instructions
Remove cream cheese from the fridge 30 minutes before starting. Zest lemons first (1 tbsp packed), then juice them until you have ¾ cup fresh lemon juice; remove any seeds and set both aside.
Stir together graham cracker crumbs, sugar, and melted butter until the mixture resembles wet sand and holds together when pressed. Press firmly and evenly into the bottom and up the sides of a 9-inch pie dish, then freeze for 10 minutes.
Using a hand mixer or stand mixer, beat the softened cream cheese on medium speed for about 2 minutes until completely smooth and lump-free, scraping down the sides of the bowl halfway through.
With the mixer on low, add both cans of sweetened condensed milk to the cream cheese and mix until smooth, then add the fresh lemon juice and lemon zest and beat on medium for 1 to 2 minutes until thick and well combined. Taste and adjust tartness or sweetness if needed.
Pour the lemon filling into the chilled crust and spread into an even layer with a rubber spatula, then gently tap the dish on the counter to remove air bubbles. Cover loosely with plastic wrap (without touching the surface) and freeze for at least 4 hours, or overnight for best results.
Beat cold heavy whipping cream on medium-high speed until soft peaks form, add powdered sugar, then increase to high and beat until stiff peaks form — do not overbeat.
Let the pie sit at room temperature for 10 to 15 minutes to soften slightly, then top with whipped cream, lemon slices, and extra zest. Run a sharp knife under hot water and wipe dry between each slice for clean cuts.
Notes
Always use freshly squeezed lemon juice — bottled juice produces a flat, processed flavor that's noticeably different in a pie where lemon is the star.
Soften cream cheese fully (30 to 45 minutes at room temperature) before mixing to ensure a completely smooth, lump-free filling.
For the cleanest slices, freeze the pie overnight rather than just 4 hours — the filling sets firmer and holds its shape much better when cut.
Use full-fat block cream cheese only. Low-fat or spreadable varieties contain more water and will result in a thinner, less stable filling.
Always chill the crust in the freezer for 10 minutes before adding the filling — this prevents it from becoming soggy and helps it hold its shape.
Add the whipped cream topping just before serving. Made hours in advance, it can weep and lose its texture.
For a softer, mousse-like consistency, refrigerate the pie instead of freezing it — it sets in 3 to 4 hours and keeps for up to 4 days in the fridge.
To store, wrap tightly with plastic wrap or place in an airtight container and freeze for up to 2 weeks. Wrap leftover individual slices and freeze for up to 1 week.
Crust variations: use vanilla wafer crumbs, gingersnap crumbs, or chocolate graham crackers in place of regular graham crackers for a different flavor profile.
For a Key Lime Icebox Pie, simply swap the lemon juice and zest for the same quantities of fresh Key lime juice and zest.
