A creamy, no-bake key lime pie with fresh lime juice and zest in a buttery graham cracker crust that chills to a silky, sliceable finish. Perfect make-ahead dessert with bright citrus flavor and cloud-like texture.
For best flavor, use fresh lime juice and zest. Pack the crust tightly to prevent crumbling. Chill overnight for clean slices. If desired, bake the crust at 350°F (175°C) for 8–10 minutes and cool before filling. Variations: add toasted coconut to the filling, use a gingersnap crust, or add 1 tablespoon orange liqueur for a margarita twist.
