I still remember the first time I cracked open a frozen Edwards Key Lime Pie at my sister's house in July. One bite of that cold, tangy custard and I was hooked, but I wanted to make it at home without hunting the freezer aisle. So I spent a few weekends testing, tasting, and adjusting until my family said it tasted just like the box.

The secret is simpler than you think: real lime juice, sweetened condensed milk, and egg yolks do almost all the work. The oven only sets the filling gently, then the fridge finishes the job and gives you that signature creamy, sliceable texture.
If you have ever worried that key lime pie is fussy, this is the version that proves otherwise. No water bath, no pastry skills, and you probably already own the pan.
Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (150g) graham cracker crumbs (about 12 full sheets)
Pulse whole crackers in a food processor or crush them in a zip-top bag with a rolling pin. Shortbread cookies or digestive biscuits work as a swap if you want a richer crust.
1/3 cup (67g) granulated sugar
This sweetens the crust just enough to balance the tart filling. You can use light brown sugar for a slightly caramel note, but reduce it to 1/4 cup.
7 tablespoons (99g) salted butter, melted
Salted butter keeps the crust from tasting flat; if you only have unsalted, add a pinch of fine salt. Melt it in the microwave in 20-second bursts so it does not spatter.
4 large egg yolks, room temperature
Room-temperature yolks blend smoothly and set more evenly. Save the whites for an omelet or meringue; do not substitute the yolks with whole eggs here.
1 can (14 oz / 397g) sweetened condensed milk
This is the creamy backbone of the pie, so use the full-fat canned version. Do not swap in evaporated milk, which is unsweetened and much thinner.
1/2 cup (120ml) fresh key lime juice (about 20-24 key limes)
Key limes are more floral and tart than Persian limes, but regular lime juice works in a pinch. Roll the limes on the counter before juicing to get more liquid out.
1 tablespoon fresh lime zest (from about 4-5 limes)
Zest only the green layer; the white pith underneath is bitter. A Microplane grater gets fine zest without any pith.
1 cup (240ml) cold heavy whipping cream
Cold cream whips faster and holds peaks better. For a lighter topping, use 3/4 cup cream plus 1/4 cup Greek yogurt.
2 tablespoons (15g) powdered sugar
Powdered sugar dissolves instantly and will not leave a gritty texture. If you are out, blend 2 tablespoons granulated sugar in a spice grinder.
1 teaspoon vanilla extract
A little vanilla rounds out the tart lime. Imitation vanilla works, but pure extract tastes cleaner in a no-bake topping.
Tips & Tricks
Do not overbake the filling
Pull it when the center still jiggles slightly, because it firms up completely as it chills.
Zest before you juice
It is nearly impossible to zest a squeezed lime, and the oils in the peel carry most of the aroma.
Chill overnight if you can
Four hours works, but a full night gives you the cleanest, creamiest slices.
Wipe your knife between cuts
A warm, clean blade makes each slice look bakery-perfect instead of smeared.
Pro Tips
Step-by-Step Instructions
1. Heat oven and prep pan
Preheat your oven to 350F (175C) and lightly grease a 9-inch pie plate. This temperature sets the crust without browning the filling too fast.
2. Make the crust
Stir the graham crumbs, granulated sugar, and melted butter until it looks like wet sand. Press the mixture firmly up the sides and across the bottom of the pie plate.
3. Bake the crust
Bake for 8 to 10 minutes, until the edges look toasted and smell nutty. It should be golden brown and set when you touch it, so let it cool for 10 minutes before adding filling.
4. Whisk the filling
In a large bowl, whisk the egg yolks and lime zest for 30 seconds, then whisk in the sweetened condensed milk. Add the lime juice and stir gently until the mixture thickens slightly, about 1 minute.
5. Bake the filling
Pour the filling into the cooled crust and bake at 350F (175C) for 15 to 18 minutes. The center should jiggle like set gelatin and reach about 170F (77C) on an instant-read thermometer.
6. Cool and chill
Let the pie cool on a wire rack for 1 hour, then refrigerate for at least 4 hours or overnight. Chilling is what turns the loose custard into that signature creamy slice.
7. Whip the topping
Beat the cold heavy cream, powdered sugar, and vanilla on medium-high until soft peaks form, about 2 to 3 minutes. Stop when the beaters leave a trail that slowly settles.
8. Finish and serve
Spread or pipe the whipped cream over the chilled pie and garnish with extra lime zest. Slice with a warm knife and serve cold straight from the fridge.
Delicious Variations
Coconut Key Lime Pie
Swap 1/4 cup of the graham crumbs for toasted shredded coconut and add 1/2 teaspoon coconut extract to the filling.
Chocolate-Dipped Crust
Brush the baked crust with 2 ounces of melted dark chocolate and chill 10 minutes before adding filling for a crunchy layer.
Berry Swirl
Fold 1/3 cup of raspberry puree through the filling in three strokes before baking for a pretty marbled look.
How to Store Edwards Key Lime Pie Copycat Recipe
Refrigerator
Cover tightly with plastic wrap pressed to the surface or store in an airtight pie keeper for up to 4 days. Keep it cold until the moment you serve it.
Freezer
Freeze the fully set pie without the whipped topping for up to 2 months. Wrap it in two layers of plastic and one of foil, then thaw overnight in the fridge.
Reheating
Do not reheat this pie; it is meant to be served cold. If it sat out too long, return it to the fridge for 1 hour to firm back up.
Frequently Asked Questions
Q: Can I use regular limes instead of key limes?
Yes, regular Persian limes work perfectly and are much easier to find. Use the same 1/2 cup of fresh juice, though the flavor will be slightly less floral and a touch more acidic.
Q: Why is my key lime pie runny?
A runny pie usually means the filling was underbaked or not chilled long enough. Bake until the center jiggles gently like set gelatin, then refrigerate at least 4 hours or overnight before slicing.
Q: Do I have to bake key lime pie?
Traditional key lime pie is baked because the egg yolks need heat to set safely and give the custard structure. A no-bake version can work with pasteurized eggs, but the texture will be softer and less sliceable.
Q: How many limes do I need for 1/2 cup of juice?
Key limes yield about 1 to 1 1/2 teaspoons each, so plan on 20 to 24 of them. If you use regular Persian limes, 4 to 6 medium limes will give you the same 1/2 cup.
Q: Can I make this pie ahead of time?
Yes, this is an ideal make-ahead dessert and actually tastes best after chilling overnight. Add the whipped cream topping the same day you serve it so it stays fluffy.
Next time you are at the store, grab a bag of key limes instead of the frozen pie, and try this copycat for your family this weekend. I would love to hear how it turned out, so leave a comment with your favorite twist. Here's to small steps, together.
