Instructions

Step 1: Preheat oven to 350°F (175°C). Mix 1 1/2 cups crushed graham crackers with 6 tbsp melted unsalted butter until combined. Press firmly into the bottom and up the sides of a 9-inch pie dish. Bake for 8 minutes until set, then cool completely.
Step 2: In a large bowl, whisk together 1/2 cup key lime juice, 1 can sweetened condensed milk, 3 egg yolks, and 1 tsp vanilla extract until smooth and no lumps remain.
Step 3: Pour the filling into the cooled crust. Bake for 15-18 minutes until the edges are set but the center still has a slight jiggle — do not overbake.
Step 4: Chill in the refrigerator for at least 4 hours. Just before serving, top with 1/2 cup whipped cream and a sprinkle of lime zest for extra sour brightness.
