4 Ingredients for Lemon Pie
Just four pantry-friendly ingredients (plus a graham cracker crust) create the filling for this luscious pie.
- Sweetened Condensed Milk – provides the silky, sweet base for the filling.
- Egg yolks – add richness, help thicken, and give a lovely color (save the whites for meringue, angel food cake, or macarons).
- Fresh lemon juice – the star ingredient. Use a fine-mesh strainer if you prefer a pulp-free filling.
- Cool Whip – folded in for lightness; found in the frozen dessert section.
Optionally, add the zest of one lemon to intensify the flavor and aroma. Zest the lemon before juicing it and use a microplane for best results.

Most lemons yield about 2–3 tablespoons of juice. Plan on 4–6 lemons to yield roughly 3/4 cup, though juice yield varies by size and ripeness.
Graham Cracker Crust Recipe
Buying a pre-made crust saves time, but making your own is easy. For a 9–10 inch pie, you’ll need:
- 1 ½ cups graham cracker crumbs (about 10–12 crackers)
- ¼ cup granulated sugar
- ½ cup unsalted butter, melted
To make the crust:
- Preheat the oven to 350°F (175°C).
- Crush the graham crackers in a food processor or with a rolling pin.
- Mix crumbs with sugar and melted butter until evenly combined.
- Press the mixture firmly into a 9–10 inch pie dish using the back of a spoon or your fingers.
- Bake for 8–10 minutes to set, or chill in the refrigerator for 30 minutes if you prefer not to bake.
With the crust ready, you can prepare the filling.
How to make Creamy Lemon Pie Filling
The filling comes together quickly:
- Preheat the oven to 350°F (if you haven’t already).
- In a large bowl, whisk together sweetened condensed milk, fresh lemon juice, and egg yolks until smooth.
- Fold in Cool Whip and lemon zest (optional) until evenly incorporated.
- Pour the filling into the prepared graham cracker crust.
- Bake for 20 minutes, then remove from the oven and let cool to room temperature (about 1 hour).
- Chill in the refrigerator for at least 2–3 hours or overnight; this pie is best served cold.
After chilling, serve the pie as is or top with whipped cream and lemon slices for a pretty finish.

Top with Whipped Cream
Homemade whipped cream complements the tart filling beautifully. You’ll need:
- 1 cup heavy whipping cream (cold)
- 3 tablespoons powdered sugar
- 1 teaspoon vanilla or lemon extract
For extra stability, chill the mixing bowl and whisk for 15–20 minutes before whipping.
To make whipped cream:
- Beat the cold heavy cream on medium speed until it begins to thicken (1–2 minutes).
- Add powdered sugar and vanilla or lemon extract, increase to high speed, and whip until stiff peaks form. Stop before over-whipping or it will turn into butter.
