If you love bright, creamy desserts with a perfect balance of sweet and tangy flavors, this Key Lime Pie is a must-try. Made with sweetened condensed milk, fresh key lime juice, sour cream, and lime zest, the filling is incredibly smooth and flavorful.
The graham cracker crust adds the perfect buttery crunch, while a short bake helps the filling set without losing its creamy texture. Chill it well before serving for the best results.
🛒 Ingredients
- 3 cups sweetened condensed milk
- ¾ cup key lime juice
- ½ cup sour cream
- 1 tablespoon grated lime zest
- 1 (9-inch) prepared graham cracker crust
- Lime slices and whipped cream, for garnish, optional
👩🍳 Instructions
1. Preheat the Oven
Preheat your oven to 350°F (175°C). Place the prepared graham cracker crust on a baking sheet.
2. Make the Filling
In a large bowl, combine the sweetened condensed milk, key lime juice, sour cream, and grated lime zest. Mix until the filling is completely smooth and well combined.
3. Fill the Crust
Pour the lime filling evenly into the prepared graham cracker crust.
4. Bake
Bake for 5–8 minutes, just until tiny pinhole bubbles begin to appear on the surface. The filling should still look slightly wobbly and should not be browned.
5. Cool and Chill
Transfer the pie to a wire rack and allow it to cool. Once cooled, refrigerate until thoroughly chilled, about 1 hour.
For an even firmer, cleaner slice, you can chill the pie longer.
6. Garnish and Serve
Before serving, garnish with lime slices and a generous dollop of whipped cream if desired.
⭐ Tips for the Best Key Lime Pie
- Use real key lime juice when available for the classic flavor.
- Don’t overbake: The filling should remain slightly wobbly when it comes out of the oven.
- Chill thoroughly: Refrigeration helps the filling set and makes slicing much easier.
- Add the zest: Fresh lime zest gives the pie an extra burst of citrus flavor.
- For clean slices: Use a sharp knife and wipe it clean between cuts.
