Ingredients
- Sweetened condensed milk: This forms the basis of the filling and gives it a creamy texture.
- Key lime juice: This is what provides that tart and citrusy flavor to the pie.
- Grated lime zest: This adds flavor and aroma to the recipe.
- Granulated sugar: Used for sweetness in the recipe.
- Unsalted butter melted: Used to make the graham cracker crust.
- Graham cracker crumbs: This is what makes up the crust of the pie.

Step by Step Directions
Step 1
Prepare the mixture for the crust. In a bowl, mix together graham cracker crumbs and melted butter until all of the ingredients are well combined.
Step 2
Press the mixture into a 9-inch pie dish. Make sure to evenly spread out and press down the mixture so that it forms a crust at the bottom of the dish. Place it in a preheated oven at 350°F for about 10 minutes.
Step 3
In a large bowl, whisk together sweetened condensed milk, key lime juice, grated lime zest, and granulated sugar until all of the ingredients are fully combined.
Step 4
Once the crust has cooled down, pour the mixture into it and spread it evenly across the surface.
Step 5
Bake it for about 25 minutes at 350°F until the top starts to turn golden brown.
Step 6
Remove it from the oven and let stand for a few hours, preferably overnight. Right before serving, spread sour cream over the surface of the pie and garnish with key lime wedges.
Notes
- It is important to use freshly squeezed key lime juice for this recipe in order to get the best flavor.
- If you find the pie is too tart, add more condensed milk or sugar until it reaches your desired sweetness.
- You can also top the pie with whipped cream instead of sour cream if you prefer.
