Ingredients:

  • 1.5 cups (150g) graham cracker crumbs
  • 1/3 cup (75g) granulated sugar
  • 6 tbsp (85g) unsalted butter, melted
  • 2 large egg yolks, room temperature
  • 1 can (14 oz / 397g) sweetened condensed milk
  • 1/2 cup (120ml) key lime juice
  • 1 tbsp (6g) fresh key lime zest

Instructions:

  1. Mix graham cracker crumbs, sugar, and melted butter until it resembles wet sand. Press firmly into the bottom and up the sides of a 9-inch pie plate.
  2. Bake the crust at 350°F (175°C) for 8–10 minutes until it smells nutty and looks golden brown. Remove and let cool completely.
  3. Whisk egg yolks until smooth and slightly pale.
  4. Beat in the sweetened condensed milk until fully combined.
  5. Slowly stir in the key lime juice and zest until the filling noticeably thickens and becomes glossy.
  6. Pour the filling into the cooled crust.
  7. Bake at 350°F (175°C) for 12–15 minutes until the edges are set but the center still has a slight, jelly-like jiggle.
  8. Cool to room temperature, then refrigerate for at least 4 hours to set.
