  • 0.333 cup granulated sugar
  • 0.5 cup unsalted butter, melted

Preparation Steps

  • Preheat oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper, leaving overhang on sides.
  • In a medium bowl, combine graham cracker crumbs, sugar, and melted butter. Press firmly into the bottom of the prepared pan to form an even crust.
  • Bake crust for 10 minutes, then remove from oven and let cool slightly while preparing filling.
  • In a large bowl, whisk together sweetened condensed milk, key lime juice, lime zest, and egg yolk until smooth and well combined.
  • Pour filling over warm crust and spread evenly. Return to oven and bake for 20–25 minutes, or until set around the edges but still slightly jiggly in the center.
  • Remove from oven and cool completely at room temperature, then refrigerate for at least 2 hours before cutting into bars.
  • Optional: Top with whipped cream or meringue before serving.

Notes

For best flavor, use freshly squeezed key lime juice and zest. Store leftovers covered in the refrigerator for up to 5 days.
