Ingredients

  • Sweetened condensed milk: 3 cups for rich sweetness and creamy texture. Choose a high-quality brand for best results
  • Key lime juice: ¾ cup for bright tart flavor. Fresh-squeezed is ideal but high-quality bottled varieties work as a shortcut
  • Sour cream: ½ cup to add a tangy creaminess and balance the sweetness
  • Lime zest: 1 tablespoon grated for intense lime aroma and vibrant color
  • Prepared graham cracker crust: 9 inch for a buttery crisp base that complements the creamy filling

Mix the Filling:
In a large mixing bowl combine condensed milk key lime juice sour cream and lime zest. Stir or whisk until smooth and fully blended, making sure there are no lumps
Assemble the Pie:
Pour the filling mixture into the prepared graham cracker crust spreading it evenly. Place the pie on a baking sheet to ensure it bakes evenly and to catch any spills
Bake the Pie:

Cool and Chill:
Transfer the pie to a wire rack and allow it to cool completely. Then refrigerate for at least 1 hour until fully chilled and set. The chilling enhances the flavors and ensures the perfect sliceability
