INGREDIENTS NEEDED FOR KEY LIME PIE
A traditional key lime pie recipe uses only a few basic ingredients, which come together to form a pie that is packed with flavor. However, the quality of the ingredients is key to creating a pie that stands out.

FOR THE GRAHAM CRACKER CRUST:
- 1 ½ cups of graham cracker crumbs – This is the foundation of your crust. You can either purchase pre-made crumbs or crush graham crackers yourself.
- ¼ cup of granulated sugar – Sugar adds sweetness to the crust, balancing the tartness of the filling.
- ¼ teaspoon of salt – Salt is essential to bring out the sweetness and help enhance the other flavors in the pie.
- 6 tablespoons of unsalted butter (melted) – Butter helps bind the crumbs together and creates a rich, smooth texture in the crust.
FOR THE FILLING:
- 2 cans (14 ounces) of sweetened condensed milk – This is the key ingredient that gives the pie its creamy and sweet filling. It’s essential to use sweetened condensed milk and not regular milk.
- ½ cup of fresh key lime juice (about 20 key limes) – Fresh key lime juice gives the pie its signature tart and tangy flavor. If you can’t find key limes, bottled juice will work, but fresh juice is always preferred.
- 4 large egg yolks – The egg yolks help the filling set and add a richness to the custard-like texture.
- 1 tablespoon of lime zest (optional) – Zest adds an extra punch of lime flavor and aroma, perfect for enhancing the pie.
FOR THE TOPPING:
- 1 cup of heavy whipping cream – Fresh whipped cream adds a light, fluffy texture to the pie and balances out the richness of the filling.
- 2 tablespoons of powdered sugar – Powdered sugar is ideal for whipped cream because it dissolves easily and gives it a smooth, sweet taste.
- 1 teaspoon of vanilla extract – Vanilla helps to round out the flavor of the whipped cream and adds depth to the pie.
STEP-BY-STEP INSTRUCTIONS FOR MAKING KEY LIME PIE
Now that we have our ingredients, let’s dive into the step-by-step instructions for making a perfect key lime pie. Follow these carefully to get the most out of this classic recipe.
STEP 1: MAKE THE GRAHAM CRACKER CRUST
The crust is an essential part of key lime pie and should not be overlooked. To make the ideal graham cracker crust, follow these steps:

- Preheat the oven to 350°F (175°C). This guarantees that the crust will bake uniformly and crisp up properly.
- Mix the crust ingredients in a medium-sized bowl. Add the salt, granulated sugar, and graham cracker crumbs together.
- Add the melted butter to the mixture and stir until all the crumbs are evenly coated with butter. You should have a texture that resembles wet sand.
- Press the mixture into a 9-inch pie dish. Using your fingers or the back of a spoon, firmly push the mixture into the sides and bottom of the pie pan.To keep from shattering after baking, the crust is broken and evenly dispersed.
- Bake the crust in the preheated oven for 8-10 minutes or until it is golden brown and smells fragrant. This will create a crisp, buttery base that complements the creamy lime filling.
- Allow the crust to cool completely on a wire rack while you prepare the filling.
STEP 2: MAKE THE FILLING
The filling is what makes key lime pie so special. It’s smooth, creamy, and perfectly tart. Here’s how to prepare it:
- Whisk the sweetened condensed milk and egg yolks in a medium bowl until smooth and creamy.
- Add the fresh key lime juice to the mixture and stir gently. The acidity of the lime juice will cause the filling to thicken as it combines with the egg yolks.
- Optionally, add lime zest for a boost of fresh lime flavor and an extra aromatic kick. This step is particularly helpful if you want to bring out the natural flavors of the limes even more.
- Pour the lime filling into the cooled crust. Use a spatula to spread the filling evenly, ensuring it’s level.
STEP 3: BAKE THE PIE
Once the filling is in the crust, it’s time to bake the pie.
- Bake the pie at 350°F (175°C) for 15-20 minutes. You’ll know it’s done when the edges of the filling are set but the center still jiggles slightly.
- Let the pie cool to room temperature for about 30 minutes before transferring it to the fridge to chill.
- Refrigerate the pie for at least 3 hours, but ideally, let it chill overnight. This will help the filling set and the flavors meld together.
STEP 4: MAKE THE WHIPPED CREAM TOPPING
No key lime pie is complete without a fluffy, sweet whipped cream topping. Here’s how to make the perfect whipped cream:
- Chill your mixing bowl and beaters in the fridge for about 10-15 minutes before whipping the cream. As a result, the cream whips up more quickly and effectively.
- Beat the heavy whipping cream on high speed using an electric mixer. Add the powdered sugar and vanilla extract once the cream begins to thicken.
- Continue beating until stiff peaks form. You should be able to lift the beaters out of the whipped cream, and it should hold its shape.
- Spread or pipe the whipped cream generously over the chilled pie. You can either spread it evenly over the surface or pipe it into decorative peaks for a more elegant presentation.
STEP 5: SERVE AND ENJOY
Your key lime pie is now ready to be served! Cut the pie into slices and garnish with lime slices or extra lime zest, if desired. This beautiful dessert is sure to be a hit at any gathering, bringing a taste of the Florida Keys to your home.

TIPS FOR MAKING THE BEST KEY LIME PIE
To make sure you get the best key lime pie recipe, here are a few tips and tricks to help:
1. USE FRESH KEY LIMES
If you want the best key lime pie in Key West, always use fresh key lime juice. The distinctive tartness and flavor of fresh key limes are what make the pie so special. If fresh limes aren’t available, bottled key lime juice will work, but the flavor won’t be as vibrant.
2. BE MINDFUL OF THE BAKING TIME
Don’t overbake the pie. The filling should be set at the edges but still slightly wobbly in the center. Overbaking can result in a curdled texture, which is undesirable.
3. CHILL THE PIE PROPERLY
For the best texture and flavor, let your pie chill for at least 3 hours or, even better, overnight. This allows the filling to fully set and the flavors to meld together.
4. ADD DECORATIVE TOUCHES
To make your key lime pie visually appealing, garnish it with thin lime slices or a sprinkle of lime zest before serving. You can even add a few mint leaves for extra color and freshness.
