Recipe Ingredients

Only Six ingredients are needed to make this Easy Key Lime Pie.

Graham Crackers: Used to create the crust, providing a sweet and slightly coarse base that complements the creamy filling.

Butter: Binds the graham cracker crumbs together, adding richness and flavor to the crust while helping it to solidify during baking.

Sugar: Sweetens the graham cracker crust, enhancing its overall taste and contributing to its texture.

Sweetened Condensed Milk: Forms the base of the filling, providing sweetness, creaminess, and a thick texture that helps the pie set properly.

Key Lime Juice: The star ingredient, offering a distinctive tangy and citrusy flavor that defines Key Lime Pie.

Whipped Topping: Adds a light, airy texture to the filling, making it fluffier and more appealing. It also contributes to the overall sweetness and creaminess of the pie.

How to Make Easy Key Lime Pie

Making this Key Lime Pie couldn’t be easier.  Below are the basic steps, see full recipe for details.

1. Make the Crust

In a small bowl, mix the finely crushed graham crackers, melted butter, and sugar. Ensure the butter is evenly distributed so the crust holds together well. Press the mixture firmly into the bottom and up sides of pie plate. Use the bottom of a measuring cup or your fingers to create an even and compact layer. Bake 8 to 10 minutes until golden brown. Cool completely before adding the filling.

2. Make the Filling

Use an electric mixer, medium speed, to beat the milk and lime juice together until the mixture is smooth and thickened. This usually takes about 2-3 minutes. The lime juice will react with the milk, causing it to thicken. Gently fold in the thawed whipped topping until it is evenly distributed throughout the mixture. Be careful not to overmix, as this can deflate the whipped topping.

3. Assemble and Chill

Spoon the Key lime filling into the cooled graham cracker crust, spreading it evenly. Cover the pie with plastic wrap or aluminum foil and refrigerate for at least 1 hour, or until the filling is set. Chilling allows the filling to firm up and the flavors to meld together.

Storage

Refrigerator

Promptly refrigerate any leftovers. Key lime pie contains dairy products which require refrigeration to prevent spoilage.  The pie will remain fresh for up to 3 days.

Freezer

Freezing is not recommended for this type of pie. Freezing and thawing can significantly alter the texture of the filling, causing it to become watery and less appealing. The crust may also become soggy.
