This easy key lime pie is a simple no-bake dessert with a graham cracker crust and 4-ingredient creamy filling! It's has a refreshing sweet taste that's perfect for summer.
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.
Notes
Note: For a softer/tarter filling, use sour cream. For a creamier/firmer filling, use cream cheese. To make things easier buy Key lime juice.
