What You’ll Need

Gathering your ingredients ahead of time makes the baking process smoother and more enjoyable. Here’s everything you’ll need to create this sublime dessert.

For the Crust:
1 ½ cups graham cracker crumbs (about 10-12 full crackers)
¼ cup granulated sugar
½ teaspoon ground cinnamon (optional, but adds a lovely warmth)
6 tablespoons unsalted butter, melted

For the Filling:
4 large egg yolks
1 (14-ounce) can sweetened condensed milk
½ cup fresh key lime juice (from about 8-10 key limes, or bottled key lime juice)
1 teaspoon key lime zest

For Garnish (Optional):
Whipped cream
Extra lime slices or zest

Preparation Instructions

Crafting the perfect Key Lime Pie is a straightforward process that yields incredible results. From pressing the buttery crust to chilling the zesty filling, each step ensures a delightful Graham Cracker Pie experience. Follow these detailed instructions for a flawless dessert.

1. Prepare the Crust: Preheat your oven to 350°F (175°C). In a medium bowl, combine the graham cracker crumbs, granulated sugar, and ground cinnamon (if using). Pour in the melted butter and mix thoroughly until all the crumbs are moistened and resemble wet sand. Press this mixture firmly and evenly into the bottom and up the sides of a 9-inch pie plate.
2. Bake the Crust: Bake the pressed crust for 8-10 minutes, or until it’s lightly golden and fragrant. This pre-baking step helps create a sturdy, crispy base. Remove the crust from the oven and let it cool completely on a wire rack.
3. Prepare the Filling: While the crust cools, begin making the luscious key lime filling. In a large mixing bowl, whisk together the four large egg yolks until they are light yellow and slightly frothy.
4. Combine Ingredients: Gradually whisk in the entire can of sweetened condensed milk until the mixture is completely smooth and well combined. This forms the rich base of your filling.
5. Add Key Lime: Slowly pour in the fresh key lime juice and add the key lime zest. Continue whisking constantly until the mixture thickens slightly. The natural acidity of the lime juice will react with the condensed milk, causing it to thicken beautifully without extensive cooking.
6. Assemble and Bake: Once the crust is fully cooled, carefully pour the prepared key lime filling into it, spreading it evenly.
7. Bake the pie for 15-20 minutes. The pie is done when the center is just set but still has a slight wobble when gently shaken. Be careful not to overbake, as this can lead to cracks in the filling.
8. Chill: Remove the pie from the oven and allow it to cool completely on a wire rack at room temperature. Once cooled, transfer the pie to the refrigerator and chill for a minimum of 4 hours, or ideally overnight, before serving. This crucial chilling time allows the pie to fully set and for the flavors to meld.
9. Serve: Before serving, optionally garnish your Classic Key Lime Pie with a dollop of fresh whipped cream and a few extra key lime slices or a sprinkle of zest for a beautiful presentation. Slice and serve cold.

Fun Twists & Serving Ideas

Elevate your Key Lime Pie experience with these creative variations:

Toasted Coconut Crust: Substitute ½ cup of the graham cracker crumbs with toasted shredded coconut for a tropical twist.
Meringue Topping: Instead of whipped cream, create a fluffy meringue topping for a traditional finish.
Individual Tarts: Prepare the pie in mini tart pans for individual servings, perfect for parties.
Raspberry Swirl: Gently swirl a tablespoon or two of raspberry puree into the filling before baking for a fruity counterpoint.
Boozy Kick: Add a splash of rum or tequila to the filling (before baking) for an adult-friendly version.

FAQ

Q: Can I use regular limes instead of key limes?
A: Yes, you can! While key limes offer a distinct, slightly tarter flavor, regular Persian limes can be used as a substitute. You might need a bit more juice from regular limes, and the flavor will be slightly different but still delicious.

Q: How do I know if the pie is set?
A: The pie is set when the edges are firm and the very center still has a slight, very gentle wobble when you lightly shake the pie plate. It will firm up further during chilling.

Q: Can I make this pie ahead of time?
A: Absolutely! Key Lime Pie is an excellent make-ahead dessert. It needs at least 4 hours to chill, but it can be made a day or two in advance and stored in the refrigerator.

Q: What’s the best way to store leftover pie?
A: Store any leftover Key Lime Pie covered in the refrigerator for up to 3-4 days.

Q: Why did my pie filling crack?
A: Cracking often occurs if the pie is overbaked. Keep a close eye on it during the last few minutes of baking and remove it as soon as the center is just set with a slight wobble.
