The History of Key Lime Pie
Key lime pie originated in the Florida Keys in the late 1800s. It was made using Key limes, which are smaller and more aromatic than regular Persian limes. Early recipes often relied on canned sweetened condensed milk because fresh milk was scarce in the region.
The combination of lime juice, egg yolks, and condensed milk creates a natural chemical reaction that thickens the filling without cooking — although modern versions are baked for food safety and texture.
Today, Key lime pie is Florida’s official state pie and a beloved dessert across the United States.
Why This Recipe is So Easy
This recipe cuts down on prep time without sacrificing flavor by:

Ingredients for Easy Key Lime Pie
For the crust:
- 1 ½ cups graham cracker crumbs (about 10–12 crackers)
- ⅓ cup granulated sugar
- 6 tbsp unsalted butter, melted
(Or use a pre-made graham cracker crust for extra convenience.)
For the filling:
- 3 large egg yolks
- 1 can (14 oz) sweetened condensed milk
- ½ cup fresh Key lime juice (or regular lime juice if Key limes aren’t available)
- 1 tsp lime zest (optional, for extra flavor)
For the topping:
- 1 cup heavy whipping cream
- 2 tbsp powdered sugar
- Extra lime zest or thin lime slices for garnish
Step-by-Step: How to Make Easy Key Lime Pie
Step 1: Make the Crust
- Preheat oven to 350°F (175°C).
- In a medium bowl, mix graham cracker crumbs, sugar, and melted butter until evenly combined.
- Press mixture firmly into the bottom and up the sides of a 9-inch pie dish.
- Bake for 8 minutes, then let cool slightly. (Skip this step if using a pre-made crust.)
Step 2: Prepare the Filling
- In a mixing bowl, whisk together egg yolks and sweetened condensed milk until smooth.
- Add lime juice and lime zest, whisking until fully combined and slightly thickened.
Step 3: Fill and Bake
- Pour filling into the prepared crust.
- Bake for 12–15 minutes, until the center is set but still slightly jiggly.
- Remove from oven and cool to room temperature.
Step 4: Chill
- Refrigerate for at least 3 hours, or until fully chilled and firm.
Step 5: Add the Whipped Cream Topping
- In a chilled mixing bowl, whip heavy cream and powdered sugar until soft peaks form.
- Spread or pipe whipped cream over the chilled pie.
- Garnish with lime zest or slices.
Tips for the Best Key Lime Pie
- Use Fresh Juice – Fresh-squeezed Key lime juice has a brighter, more complex flavor than bottled juice.
- Don’t Overbake – The pie should have a slight jiggle in the center when removed from the oven; it will set as it cools.
- Chill Thoroughly – This helps the filling firm up and makes slicing easier.
- Make Ahead – Key lime pie can be made a day in advance and kept refrigerated until serving.
Key Limes vs. Regular Limes
- Key Limes – Small, thin-skinned, with a floral, tangy flavor.
- Persian Limes – Larger, more common, and slightly less tart.
If Key limes are unavailable, you can use regular limes, but for the most authentic flavor, seek out fresh or bottled Key lime juice.
Popular Variations
- Frozen Key Lime Pie – Freeze the pie for a chilled, ice cream-like treat.
- Chocolate Key Lime Pie – Add a thin layer of melted chocolate to the crust before filling.
- Coconut Key Lime Pie – Stir shredded coconut into the crust for a tropical twist.
- Mini Key Lime Pies – Make individual servings in muffin tins or ramekins.
Serving Suggestions
