Ingredients You’ll Need
For the graham cracker crust key lime pie base:
- 1 ½ cups graham cracker crumbs
- ⅓ cup granulated sugar
- ½ cup unsalted butter, melted
For the filling:
- 1 can (14 oz) sweetened condensed milk
- ½ cup fresh key lime juice (or bottled if fresh isn’t available)
- 1 tablespoon lime zest
- 1 cup heavy whipping cream, chilled
- 3 tablespoons powdered sugar
For topping:
- Additional whipped cream
- Extra lime zest or thin lime slices
Step-by-Step Instructions
1. Make the Crust
In a medium bowl, stir together graham cracker crumbs and sugar. Add melted butter and mix until the crumbs are evenly moistened. Press the mixture firmly into the bottom and slightly up the sides of a 9-inch pie dish. Place it in the fridge to set while you prepare the filling.
Tip: For a firmer base, you can bake it at 350°F for 8 minutes, but it’s not necessary for a true no-bake key lime pie.
2. Whip the Cream
In a cold mixing bowl, beat the heavy cream and powdered sugar together until soft peaks form. This is your airy foundation for the filling.
3. Make the Filling
In another bowl, whisk sweetened condensed milk, lime juice, and lime zest until smooth. Gently fold in the whipped cream until combined. You want it light, so don’t over-mix.
4. Assemble
Pour the filling into your chilled crust. Smooth the top with a spatula. Cover with plastic wrap and refrigerate for at least 4 hours, preferably overnight. The longer it chills, the better the flavors meld.
5. Serve
Top with dollops of whipped cream, a sprinkle of lime zest, or thin lime wheels. Slice and serve cold.
The Icebox Pie Secret
An old-fashioned icebox pie gets its name from the pre-refrigerator days, when desserts were set in insulated iceboxes. The magic is in the chill time—it allows the filling to firm up without baking, while keeping that luscious, melt-in-your-mouth texture.
Variations You Can Try
- Tropical Twist – Add a layer of crushed pineapple between the crust and filling.
- Coconut Cream Finish – Fold in shredded coconut for an island vibe.
- Chocolate Crust – Swap graham crackers for chocolate cookies for a sweet contrast.
- Layered Jar Desserts – Make mini versions in mason jars for parties.
Why Key Lime Works So Well
Key limes have a sharper, more floral tang than regular limes, making them perfect for tangy citrus dessert ideas. The acidity cuts through the richness of condensed milk, creating that addictive sweet-tart balance. If you can’t find fresh key limes, bottled juice is fine—just don’t skip the zest.
Serving Ideas for Summer
This pie fits right in with refreshing summer pie recipes:
- Serve with iced tea or sparkling water with lime slices.
- Pair with a fruit salad for a light finish to a heavy meal.
- Offer alongside other tropical no bake desserts for a themed party.
Storage
Cover and keep in the refrigerator for up to 3 days. You can also freeze it for up to a month—just thaw in the fridge before serving for that perfect creamy texture.
Tips Before You Try This Recipe
- Don’t skimp on chill time – The filling needs hours to firm up for clean slices.
- Taste as you go – Key lime juice can vary in tartness. Adjust with a little more sugar if needed.
- Cold tools help – Chilled bowls and beaters whip cream faster.
- Press that crust firmly – Loose crumbs will make slicing messy.
- Add flair – Toasted coconut, crushed pistachios, or even edible flowers make great finishing touches.
