  • 1 9-inch prepared graham cracker crust
  • 3 cups sweetened condensed milk
  • 1/2 cup sour cream (or cream cheese)
  • 2/3 cup key lime juice , about 1 lb bag
  • 1 1/2 Tablespoon grated lime zest , more to taste

For serving: whipped cream, lime slice, lime zest


    • Preheat oven to 350°F. 
    • In a medium bowl, whisk together the condensed milk, sour cream, lime juice and lime zest. Taste and add more lime zest if you'd like more tart. 
    • Pour mixture into prepared pie crust. Bake in preheated oven for 6-8 minutes, or until pinhole bubbles burst on the top of the pie. Be careful to not let it brown. 
    • Chill pie before serving. Store in the refrigerator. Garnish with whipped cream and lime slices or zest if desired. 


    Note: For a softer/tarter filling, use sour cream. For a creamier/firmer filling, use cream cheese.
