For the Graham Cracker Crust
- 2 cups graham cracker crumbs (about 1 sleeve)
- 1/4 cup sugar
- 6 tablespoons butter, melted
For the Key Lime Filling
- 2 cans sweetened condensed milk (14 oz each, preferably organic)
- 1/2 cup sour cream (full fat or Greek yogurt alternative)
- 2–3 Key Limes, zested (or Persian limes)
- 3/4 cup Key Lime juice (about 30 Key Limes or 9 Persian limes) or Nellie and Joe’s bottled Key Lime juice
- 2 large egg yolks
For the Whipped Cream Topping
- 8 oz heavy whipping cream, cold
- 1–2 teaspoons vanilla extract
- 2–4 tablespoons powdered sugar
- Prepare the Graham Cracker Crust: Preheat your oven to 350°F (175°C). Crush the graham crackers finely using a food processor, blender, or by placing them in a freezer bag and rolling with a rolling pin. Mix the graham cracker crumbs with sugar, then add melted butter and combine thoroughly. Reserve 1/4 cup of crumbs for topping if desired.
- Bake the Crust: Press the crumb mixture evenly into the bottom and up the sides of a 9-inch deep dish pie pan using your hands. Bake in the preheated oven for 6-8 minutes until just golden. Remove and let cool completely on a wire rack; you may speed this up by cooling in the freezer for 20-30 minutes after an initial 10 minutes on the rack.
- Prepare Lime Zest and Juice: Wash and dry your limes. Zest 2-3 Key Limes and set zest aside. Squeeze fresh lime juice until you have 3/4 cup, which usually requires about 30 Key Limes or 9 Persian limes. If using bottled lime juice, use high-quality like Nellie and Joe’s.
- Mix the Filling: In a stand mixer bowl, combine the lime juice, sweetened condensed milk, sour cream, egg yolks, and lime zest. Mix on low speed until incorporated, then increase to medium-high speed for 2-3 minutes until the mixture thickens, scraping down the sides once or twice to ensure even mixing.
- Bake the Filling: Pour the lime filling into the cooled graham cracker crust. Bake at 350°F (175°C) for 15-20 minutes until the center is set but still slightly jiggly. Do not allow the pie to brown. Remove from oven and cool on a rack for 30 minutes, then refrigerate for at least 3 hours, preferably 6 or more, to let it fully set.
- Make Whipped Cream: While the pie cools, pour cold heavy cream into a chilled bowl and whip until stiff peaks form. Add vanilla extract and powdered sugar, then whip again at medium-high speed until thick and almost buttery in texture.
- Assemble and Garnish: Transfer whipped cream to a piping bag fitted with a star tip. Pipe decoratively over the chilled pie. Garnish with reserved graham cracker crumbs, additional lime zest, and a slice of lime. Keep refrigerated until ready to serve.
Notes
- You can substitute Greek yogurt for sour cream for a tangier taste and thicker texture.
- Use fresh Key Lime juice for authentic flavor; bottled juice is a convenient alternative if necessary.
- If pressed for time, cooling the crust in the freezer after initial cooling helps speed up preparation.
- Mini Key Lime pies can be made using the same proportions; reduce baking time slightly and watch for set filling.
- Whipped cream can be kept refrigerated in a piping bag for several hours before decorating.
