Ingredients
1 1/2 cups graham cracker crumbs
1/3 cup granulated sugar
6 tbsp butter, melted
2 cans (14 oz each) sweetened condensed milk
1/2 cup light sour cream
3/4 cup key lime juice (fresh or bottled)
1 tbsp lime zest
1 cup heavy whipping cream
1/4 cup powdered sugar
1 tsp vanilla extract
Instructions
- Preheat oven to 375°F (190°C). In a small bowl, mix graham cracker crumbs, granulated sugar, and melted butter. Press mixture firmly into an 8–9.5 inch pie pan. Bake for 7 minutes. Let cool for at least 30 minutes.
- Reduce oven temperature to 350°F (175°C). In a medium bowl, whisk together sweetened condensed milk, sour cream, key lime juice, and lime zest until smooth.
- Pour filling into cooled crust and bake for 10 minutes. The filling will not expand during baking.
- Cool slightly, then refrigerate for at least 3 hours until set.
- In a mixing bowl, whip heavy cream and powdered sugar until stiff peaks form. Beat in vanilla extract. Spread or pipe whipped cream over chilled pie and garnish with extra lime zest if desired.
Notes
- Fresh key limes provide the most authentic flavor, but bottled juice works well.
- For a twist, try grapefruit or blood orange juice.
- Greek yogurt can replace sour cream for a tangier filling.
- The pie freezes well; thaw overnight in the refrigerator before serving.
- Bake crust fully before adding filling to prevent sogginess.
