  • Yield:


  • 1 1/2 cups graham cracker crumbs
  • 1/2 cup granulated sugar
  • 4 tablespoons (1/2 stick) unsalted butter, melted
  • Two 14-ounce cans condensed milk
  • 1 cup fresh Key lime or regular lime juice
  • 2 large eggs
  • 1 cup sour cream
  • 2 tablespoons confectioners' sugar
  • 1 tablespoon lime zest, for garnish


  • Preheat the oven to 375 degrees F.

  • Combine the graham cracker crumbs, sugar, and butter in a medium bowl. Press together with your hands. Press the mixture firmly onto the bottom and up the sides of a 9-inch pie pan, and bake until brown, about 15 minutes. Remove the crust from the oven and allow to cool completely before filling.

  • Reduce the heat to 325 degrees F.

  • Combine the condensed milk, lime juice, and eggs in a large bowl. Whisk until well blended, then pour the filling into the cooled pie shell. Bake for 15 minutes; allow to cool in the refrigerator for at least 2 hours.

  • Once chilled, combine the sour cream and confectioners' sugar and spread over the top of the pie with a spatula. Sprinkle the lime zest on top as a garnish and serve chilled.
