Ingredients You’ll Need

(Serves 8 | Prep Time: 15 minutes | Bake Time: 15 minutes | Chill Time: 2+ hours)

For the Graham Cracker Crust:

  • 1 1/2 cups graham cracker crumbs (about 12 crackers)
  • 1/3 cup granulated sugar
  • 6 tablespoons unsalted butter, melted

For the Key Lime Filling:

  • 4 large egg yolks
  • 1 can (14 oz) sweetened condensed milk
  • 1/2 cup key lime juice (fresh or bottled)
  • 1 tablespoon key lime zest

For the Whipped Topping:

  • 1 cup heavy whipping cream
  • 2 tablespoons powdered sugar
  • 1/2 teaspoon vanilla extract

How to Make Key Lime Pie (Step-by-Step)

1. Preheat the Oven

Preheat your oven to 350°F (175°C).

2. Make the Graham Cracker Crust

In a bowl, mix together the graham cracker crumbs, sugar, and melted butter until it resembles wet sand. Press the mixture into a 9-inch pie dish, covering the bottom and sides evenly.

Bake for 8-10 minutes, then set aside to cool slightly.

3. Prepare the Key Lime Filling

In a large bowl, whisk together the egg yolks, sweetened condensed milk, key lime juice, and lime zest until smooth and creamy.

Pour the filling into the cooled crust and spread evenly.

4. Bake Until Set

Bake at 350°F for 12-15 minutes, until the filling is set but slightly jiggly in the center. Remove from the oven and let it cool to room temperature before refrigerating for at least 2 hours (or overnight) to fully set.

5. Make the Whipped Cream Topping

In a mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract with an electric mixer until soft peaks form.

6. Assemble and Serve

Spread or pipe the whipped cream over the chilled pie. Garnish with extra lime zest or lime slices for a decorative touch. Slice and enjoy!


Pro Tips for the Best Key Lime Pie

  • Use fresh key limes for the best flavor! If unavailable, bottled key lime juice works.
  • Don’t skip the chilling time – it helps the pie set and enhances the flavor.
  • Make it ahead of time – this pie tastes even better after a day in the fridge!
  • For a firmer crust, chill the crust for 30 minutes before baking.

What to Serve With Key Lime Pie

  • Fresh berries – a great contrast to the creamy filling.
  • Coconut flakes – adds a tropical twist.
  • A drizzle of caramel or white chocolate for extra indulgence.
