Ingredients
| For the crust | For the filling | For the whipped cream topping |
| 150g graham cracker crumbs | 400g sweetened condensed milk | 240ml chilled heavy cream |
| 50g granulated sugar |
120ml fresh key lime juice |
2 tbsp powdered sugar |
| 85g melted butter | 1 tbsp lime zest | ½ tsp vanilla extract |
| 4 large egg yolks |

Instructions
- Prepare the crust
Preheat your oven to 350°F (175°C). In a bowl, mix graham cracker crumbs, sugar, and melted butter until combined. Press the mixture firmly into a 9-inch pie dish. Bake for 8–10 minutes, then let it cool.

- Make the filling
In a mixing bowl, whisk together egg yolks and lime zest until slightly thickened (about 2 minutes). Add condensed milk and lime juice. Mix until smooth and creamy.
- Bake the pie
Pour the filling into the cooled crust. Bake for 15 minutes, or until the center is just set. Let it cool to room temperature, then refrigerate for at least 3 hours (or overnight).
- Whip the cream
In a whipped cream dispenser, combine the heavy cream, powdered sugar, and vanilla. Charge it with one n2o cream charger, shake well, and refrigerate until serving.(If you are using a 9g cartridge, you can use it directly. If you are using a large 3.3L nitrous oxide tank, you will need to use a pressure regulator.)

Serve and enjoy
Top the chilled pie with fresh whipped cream just before serving. Garnish with extra lime zest or lime slices for a beautiful finish.
✨ Pro Tip
Using a cream charger saves time and gives your whipped topping a super light and airy texture perfect for balancing the rich citrus flavor of the pie.
