- 6 tablespoons unsalted butter, melted
- Pinch of salt
For the Lemon Filling:
- 2 (14-ounce) cans sweetened condensed milk

Step-by-Step Instructions for Classic Lemon Icebox Pie
Step 1: Prepare the Graham Cracker Crust
Preheat your oven to 350°F (175°C). In a medium bowl, combine the graham cracker crumbs, granulated sugar, and salt. Pour in the melted butter and mix until the crumbs are evenly moistened. The mixture should hold together when pressed between your fingers.
Press this mixture firmly into the bottom and up the sides of a 9-inch pie plate. Use the bottom of a measuring cup to compact the crumbs—this trick ensures a more sturdy crust that won’t crumble when sliced.
Bake the crust for 8-10 minutes until lightly golden. Remove from oven and cool completely on a wire rack before filling.
Step 2: Prepare the Lemon Filling
In a large bowl, whisk the egg yolks until slightly thickened. Add the sweetened condensed milk and continue whisking until well combined.
Gradually add the fresh lemon juice, whisking constantly. The mixture will begin to thicken naturally due to the acid in the lemon juice reacting with the milk proteins. Fold in the lemon zest, ensuring it’s evenly distributed throughout the filling.
Pro tip: Room temperature lemons yield more juice. Roll them firmly on the counter before cutting and juicing for maximum extraction.
Step 3: Assemble and Chill the Pie
Pour the lemon filling into the cooled graham cracker crust, spreading evenly with a spatula. Tap the pie dish gently on the counter to remove any air bubbles.
Cover the pie loosely with plastic wrap, making sure it doesn’t touch the filling. Refrigerate for at least 4 hours, though overnight chilling will develop the flavors more fully and create the perfect texture.
Step 4: Prepare the Whipped Cream Topping
Just before serving, place a mixing bowl and beaters in the freezer for 10 minutes—this helps achieve the fluffiest whipped cream possible.
Pour the cold heavy cream into the chilled bowl and beat on medium-high speed until soft peaks begin to form. Add the powdered sugar and vanilla extract, then continue beating until stiff peaks form, about 1-2 minutes more.
Spread or pipe the whipped cream over the chilled pie. For a decorative touch, sprinkle additional lemon zest or add thin lemon slices as garnish.

FAQs for Classic Lemon Icebox Pie
Can I make this pie without baking at all?
Yes! For a completely no-bake version, press the graham cracker crust into the pie plate and refrigerate for 2 hours before filling. The texture will be slightly more crumbly but equally delicious.
How do I know when my lemon filling is properly set?
When gently touched, the surface should feel firm with a slight give, similar to set pudding. If the center still appears liquid or excessively jiggly after 4 hours, continue refrigerating.
Can I use Meyer lemons instead of regular lemons?
Absolutely! Meyer lemons offer a sweeter, less acidic profile. Reduce the sugar in the crust by 1-2 tablespoons to balance the overall sweetness.
Why did my filling not set properly?
The most common reason is insufficient acidity. Ensure you’re using the full amount of fresh lemon juice, as the acid is what helps set the condensed milk. Also, verify your condensed milk hasn’t expired.
Is there a non-dairy version of this recipe?
Yes! Use coconut condensed milk as a substitute for traditional sweetened condensed milk, and replace the heavy cream with whipped coconut cream for the topping.
