What Ingredients You Will Need

This recipe uses simple ingredients to deliver bold flavor and a luxurious texture. Here’s what you’ll need:

• For the crust:
• 1 ½ cups (150 g) graham cracker crumbs
• ⅓ cup (75 g) granulated sugar
• 6 tablespoons (85 g) unsalted butter, melted
• For the filling:
• 4 large egg yolks
• 1 can (14 oz/396 g) sweetened condensed milk
• ½ cup (120 ml) key lime juice (freshly squeezed is best!)
• 1 teaspoon lime zest (optional, for extra flavor)
• For the topping:
• 1 cup (240 ml) heavy cream
• 2 tablespoons (25 g) powdered sugar
• 1 teaspoon vanilla extract

If you can’t find key limes, don’t sweat it—regular limes work just fine. The flavor will still be deliciously tangy!

Equipment Needed

• 9-inch pie pan
• Mixing bowls (at least two)
• Whisk or electric mixer
• Microplane or zester
• Spatula
• Food processor (optional, for crushing graham crackers)

If you don’t have a pie pan, a springform pan works as a great substitute. And for crushing graham crackers, a sturdy plastic bag and rolling pin do the trick if you don’t have a food processor. No fancy equipment required!

Preparation Method

1. Make the crust: Preheat your oven to 350°F (175°C). In a mixing bowl, combine graham cracker crumbs, sugar, and melted butter. Stir until the mixture resembles wet sand. Press the mixture evenly into the bottom and sides of a 9-inch pie pan. Bake for 8-10 minutes, then set aside to cool.
2. Prepare the filling: In a medium bowl, whisk the egg yolks until slightly thickened. Add the sweetened condensed milk and whisk until smooth. Stir in the key lime juice and zest, mixing until fully incorporated.
3. Assemble the pie: Pour the filling into the cooled crust, spreading it evenly. Bake at 350°F (175°C) for 15-18 minutes, or until the filling is set but still slightly jiggly in the center.
4. Cool and chill: Remove the pie from the oven and let it cool to room temperature. Then, refrigerate for at least 2 hours (or overnight) to allow the filling to firm up completely.
5. Make the whipped topping: In a chilled bowl, whip the heavy cream, powdered sugar, and vanilla extract together until soft peaks form.
6. Decorate: Spread or pipe the whipped cream over the chilled pie. For a final touch, sprinkle lime zest or add thin lime slices for garnish.

And just like that, you’ve got the ultimate key lime pie ready to serve. It’s easy, right?

Cooking Tips & Techniques

Here are my tried-and-true tips for making this recipe foolproof:

• Use fresh lime juice: Bottled juice can taste flat. Freshly squeezed juice brings out the vibrant tanginess that makes this pie special.
• Don’t skip the refrigeration: The pie needs time to set properly. Resist the urge to slice it too soon!
• Whip the cream just right: Soft peaks are perfect for a light, airy topping. Over-whipping can lead to grainy cream.
• Press the crust firmly: Use the bottom of a measuring cup to pack the graham cracker crust tightly for the best structure.

Trust me, these small steps make a big difference!

Variations & Adaptations

Want to mix things up? Here are some fun variations:

• Gluten-Free: Swap graham crackers for gluten-free cookies or crumbs.
• Dairy-Free: Use coconut condensed milk and coconut whipped cream for a tropical twist.
• Chocolate Twist: Add a layer of melted chocolate on the crust before adding the filling.

Personally, I love adding a pinch of sea salt to the crust for a subtle contrast to the tangy filling. It’s a game-changer!

Serving & Storage Suggestions

Here’s how to make the most of your key lime pie:

• Serve chilled for the best flavor. It’s perfect on its own or with a cup of coffee.
• Store leftovers in the refrigerator, covered with plastic wrap or foil, for up to 3 days.
• Freeze for longer storage: Wrap the pie tightly and freeze for up to 2 months. Thaw in the fridge overnight before serving.

Pro tip: The flavors deepen after a day in the fridge, so it’s even tastier the next day!
