This copycat recipe recreates the bright, creamy, and crumbly Key lime pie scent of the beloved Yankee Candle in dessert form. It works because it uses real Key lime juice and a classic graham cracker crust, delivering the same tart-sweet balance and tropical aroma that made the candle famous. The filling is silky, the crust is buttery, and the whole pie comes together in under an hour of active work.
Ingredients
- 1 ½ cups (150 g) graham cracker crumbs (about 12 full sheets)
- ¼ cup (50 g) granulated sugar
- 6 tablespoons (85 g) unsalted butter, melted
- 3 large egg yolks
- 1 (14 oz / 397 g) can sweetened condensed milk
- ½ cup (120 ml) Key lime juice (bottled or fresh, see Tips)
- 1 tablespoon (15 ml) grated lime zest (from about 2 limes)
- 1 cup (240 ml) heavy cream, cold
- 2 tablespoons (15 g) powdered sugar
- ½ teaspoon vanilla extract
- Optional: lime slices or extra zest for garnish
Instructions
- Preheat the oven to 350°F (175°C).
- Make the crust: In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter. Stir until the crumbs are evenly moistened. Press the mixture firmly into the bottom and up the sides of a 9-inch (23 cm) pie dish. Use the bottom of a measuring cup to compact it evenly.
- Bake the crust for 8–10 minutes, until lightly golden and fragrant. Remove from the oven and let cool completely on a wire rack. Leave the oven on.
- Make the filling: In a large bowl, whisk the egg yolks until smooth. Add the sweetened condensed milk and whisk until fully combined. Gradually whisk in the Key lime juice. The mixture will thicken slightly. Stir in the lime zest.
- Bake the pie: Pour the filling into the cooled crust. Bake for 12–15 minutes, until the filling is set around the edges but still slightly jiggly in the center. The internal temperature of the egg mixture should reach 160°F (71°C), the USDA FSIS safe minimum for egg dishes; check with a food thermometer inserted into the center.
- Cool: Let the pie cool completely on a wire rack, then refrigerate for at least 4 hours, or overnight, until fully chilled and firm.
- Make the whipped cream: Just before serving, beat the cold heavy cream, powdered sugar, and vanilla in a chilled bowl with an electric mixer on medium-high speed until soft peaks form. Do not overbeat.
- Serve: Spread or pipe the whipped cream over the chilled pie. Garnish with lime slices or extra zest if desired. Slice and serve cold.
Tips
- Key lime juice: Bottled Key lime juice is convenient and works well. If using fresh Key limes, you’ll need about 12–15 limes to get ½ cup (120 ml) of juice. Regular limes can be substituted, but the flavor will be slightly less floral and more tart.
- No meringue needed: This recipe uses a whipped cream topping instead of meringue, which is simpler and less prone to weeping. If you prefer meringue, you can top the pie with a Swiss meringue and brown it briefly, but the whipped cream version is classic for this style.
- Chilling is crucial: Do not skip the 4-hour chill. The filling needs time to set completely; otherwise, it will be runny and difficult to slice.
- Prevent a soggy crust: Make sure the crust is fully cooled before adding the filling. If the crust is warm, the filling will seep in and make it soft.
Serving Suggestions
Serve this pie well-chilled, straight from the refrigerator. It pairs beautifully with a dollop of extra whipped cream, a sprinkle of lime zest, or a few fresh berries for contrast. For a tropical twist, serve alongside a scoop of coconut sorbet or a slice of fresh mango. It’s perfect for summer gatherings, picnics, or any time you want a bright, citrusy dessert.
Variations
- Meringue topping: Instead of whipped cream, top the baked and cooled pie with a Swiss meringue made from 3 egg whites and ¾ cup (150 g) sugar. Brown with a kitchen torch or under a broiler for 1–2 minutes.
- Gingersnap crust: Swap the graham crackers for crushed gingersnap cookies (about 1 ½ cups / 150 g) for a spicier, warmer flavor that complements the lime.
- No-bake version: For a no-bake pie, skip the oven entirely. Mix the filling and pour into a pre-made graham cracker crust (or a crust that has been chilled, not baked). Refrigerate for at least 6 hours or overnight until set. The texture will be slightly softer but still delicious.
- Mini pies: Make individual tartlets in a muffin tin. Press the crust into muffin cups and bake for 8 minutes, then fill and bake for 10–12 minutes. Adjust chilling time to 2 hours.
Storage and Reheating
Store leftover pie in the refrigerator, covered loosely with plastic wrap or in an airtight container, for up to 3 days. The whipped cream topping may soften and weep slightly, so it’s best to add it just before serving. If you have leftover pie with whipped cream, it’s still safe to eat, but the texture will be less pristine. This pie is served cold and should not be reheated. If you want to freeze it, wrap the unfrosted pie tightly in plastic wrap and foil and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Can I use regular limes instead of Key limes? Yes, you can. Regular Persian limes are more tart and less aromatic than Key limes, but they will still produce a delicious pie. If you use regular limes, you may want to add a teaspoon of lime zest extra to boost the lime flavor.
Why is my pie runny? A runny pie is usually underbaked or not chilled long enough. Make sure the filling reaches 160°F (71°C) in the center, and then chill for at least 4 hours. Also, avoid overmixing the filling, which can incorporate too much air and cause cracks.
Can I make this pie ahead of time? Absolutely. The pie can be baked and refrigerated up to 2 days in advance. Add the whipped cream topping just before serving to keep it fresh.
Can I use bottled lime juice? Yes, bottled Key lime juice is widely available and works perfectly. Look for 100% Key lime juice, not limeade or sweetened juice. If you use regular bottled lime juice, the flavor will be slightly different but still good.
How do I know when the pie is done? The pie is done when the edges are set and the center is just barely jiggly. If you insert a knife near the edge, it should come out clean. The center will continue to set as it cools. Always check the internal temperature with a thermometer to ensure it reaches 160°F (71°C).
Can I use a store-bought crust? Yes, a store-bought graham cracker crust will save time. You can skip the crust baking step, but I recommend baking it for 8 minutes to crisp it up before adding the filling.
