The Ingredients You’ll Need
Making key lime pie doesn’t require an endless shopping list. Here’s everything you’ll need:
For the crust
1 ½ cups graham cracker crumbs (you can also use digestive biscuits if you’re in the UK)
⅓ cup granulated sugar
6 tablespoons unsalted butter, melted
For the filling
4 large egg yolks
1 can (14 oz) sweetened condensed milk
½ cup fresh key lime juice (or bottled if fresh isn’t available)
1 tablespoon lime zest
For the topping
1 cup heavy whipping cream
2 tablespoons powdered sugar
Extra lime zest for garnish
That’s it! Simple, affordable, and easy to find.
Step-by-Step Instructions
Step 1: Make the crust
Preheat your oven to 350°F (175°C).
Combine the graham cracker crumbs, sugar, and melted butter in a bowl.
Press the mixture firmly into the bottom and up the sides of a 9-inch pie dish.
Bake for 10 minutes, then set aside to cool slightly.
Step 2: Prepare the filling
In a large mixing bowl, whisk the egg yolks until slightly thickened.
Add the sweetened condensed milk and continue whisking until smooth.
Stir in the lime juice and zest until fully combined.
Step 3: Bake the pie
Pour the filling into the prepared crust.
Bake for 15 minutes until the filling is just set.
Remove from the oven and let it cool to room temperature, then refrigerate for at least 3 hours.
Step 4: Whip the topping
In a chilled bowl, whip the heavy cream and powdered sugar until soft peaks form.
Spread or pipe the whipped cream over the chilled pie.
Garnish with lime zest or thin lime slices.
That’s all it takes! You won’t believe how easy this key lime pie recipe is until you try it yourself.
Practical Tips for the Perfect Pie
1. Fresh vs. bottled lime juice
If you can find fresh key limes, use them—they provide a sharper, more authentic flavor. However, bottled key lime juice is an excellent alternative and saves time.
2. No key limes? No problem!
Can’t get key limes where you live? Regular Persian limes work wonderfully and deliver a delicious result that’s just as refreshing.
3. Avoid overbaking
The filling only needs about 15 minutes in the oven. It should look slightly wobbly in the center when you remove it. Overbaking can cause cracks in the filling.
4. Make it ahead
Key lime pie tastes even better after chilling overnight. Prepare it the day before your event, and you’ll have a dessert that’s ready to impress without last-minute stress.
5. Customize the crust
Graham crackers are traditional, but you can switch things up with digestive biscuits, vanilla wafers, or even a chocolate cookie crust for a modern twist.
Variations to Try
Mini key lime pies
Use a muffin tin and create individual pies for parties or picnics. They’re portable, adorable, and just as easy to make.
Frozen key lime pie
Skip the oven and freeze the filling for a cool summer treat. Just let it sit at room temperature for 10 minutes before serving.
Coconut key lime pie
Add shredded coconut to the crust or sprinkle it on top of the whipped cream for a tropical flair.
