Ingredients:
- 1.5 cups (150g) graham cracker crumbs
- 1/3 cup (65g) granulated sugar
- 6 tbsp (85g) unsalted butter, melted
- 2 cans (14 oz / 397g each) sweetened condensed milk
- 1/2 cup (120ml) fresh key lime juice
- 3 large egg yolks
- 1 tbsp (6g) lime zest
- 2 tbsp (30g) sour cream
- 1 cup (240ml) heavy whipping cream
- 2 tbsp (15g) powdered sugar
- 1 tsp (5ml) vanilla extract
Instructions:
- Combine graham cracker crumbs, sugar, and melted butter in a bowl until the mixture resembles wet sand.
- Press the mixture firmly into the bottom and up the sides of a 9-inch pie plate.
- Bake the crust at 350°F (175°C) for 8–10 minutes until fragrant and lightly golden, then set aside to cool completely.
- In a large bowl, whisk the egg yolks and sweetened condensed milk together until smooth and pale.
- Gradually stir in the key lime juice, lime zest, and sour cream, whisking continuously until the mixture thickens slightly.
- Pour the filling into the cooled crust and bake at 350°F (175°C) for 12–15 minutes until the edges are set but the center has a slight wobble.
- Remove from oven, cool to room temperature, and refrigerate for at least 4 hours to fully set.
- Beat heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form, then spread over the chilled pie before serving.
