Instructions
Crust
- Preheat the oven to 350°F / 180°C (fan oven).

- Melt the butter, then mix it with the crumbs until evenly combined.

- Bake for 7 to 10 minutes, then let cool completely at room temperature.
Key lime filling
- Lower the oven temperature to 320°F / 160°C (fan oven).
- In a large bowl, whisk together the sweetened condensed milk, sour cream, lime juice, and lime zest until smooth.
- Pour the filling into the cooled crust and smooth the top.
- Bake for 15 to 20 minutes, just until the filling is set.
- Let cool at room temperature for 20 minutes, then refrigerate for at least 3 hours.
Whipped cream
- Whip the cold heavy cream with powdered sugar until firm peaks form.
- Pipe or spread the whipped cream over the chilled pie.
- Finish with extra lime zest before serving.
Notes
Storage: Store the key lime pie covered in the refrigerator for up to 3 days.
Tips:
- Use a kitchen scale for best results instead of relying on cup measurements
- Fresh lime juice gives the best flavor, but bottled key lime juice also works
- Do not overbake the filling, it should be just set and still creamy
- Chill the pie well before slicing for clean slices
- Whip the cream just before serving for the best texture
