Ingredients
For the Graham Cracker Crust:
- 1 1/2 cups graham cracker crumbs (about 10 full sheets)
- 1/4 cup granulated sugar
- 6 tbsp unsalted butter, melted
Key Lime Filling Ingredients:
- 3 large egg yolks
- 1 (14 oz) can sweetened condensed milk
- 1/2 cup key lime juice (fresh or bottled, about 15-20 key limes if fresh)
- 1 tbsp key lime zest (optional, for extra zing)
For the Whipped Cream Topping:
- 1 cup heavy cream
- 2 tbsp powdered sugar
- 1/2 tsp vanilla extract
Serving:
- Optional: Lime zest, lime slices, mint leaves
- Suggested Accompaniments: Fresh berries, shortbread cookies
- Suggested Pairings: Iced tea, sparkling water
- Suggested Aesthetic: Serve on a white ceramic pie plate
- Suggested Equipment: 9-inch pie dish, food processor (optional), mixing bowls, whisk or mixer
Step-by-Step Process
- Preheat Oven and Prep Crust: Preheat oven to 350°F (175°C). In a medium bowl, mix graham cracker crumbs, sugar, and melted butter until combined. Press mixture evenly into the bottom and sides of a 9-inch pie dish. Bake for 8-10 minutes until lightly golden. Cool for 10 minutes.
- Make Filling: In a large bowl, whisk egg yolks until pale. Add sweetened condensed milk, key lime juice, and zest (if using); whisk until smooth and thickened. Pour into cooled crust.
- Bake Pie: Bake for 15-18 minutes until filling is set but slightly jiggly in the center. Cool to room temperature, then refrigerate for at least 3 hours or overnight to set.
- Make Whipped Cream: In a chilled bowl, use a whisk or mixer to beat heavy cream, powdered sugar, and vanilla until soft peaks form, about 2-3 minutes.
- Assemble and Serve: Spread or pipe whipped cream over chilled pie. Garnish with lime zest, lime slices, or mint leaves. Slice into 8 pieces and serve on a white ceramic pie plate with fresh berries, shortbread cookies, iced tea, or sparkling water.
Tips for Better Key Lime Pie
- Use fresh key limes for authentic flavor; bottled key lime juice works in a pinch.
- Crush graham crackers finely (use a food processor or rolling pin) for a cohesive crust.
- Press crust firmly to prevent crumbling; a flat-bottomed glass helps.
- Whisk filling thoroughly to ensure smoothness and avoid lumps.
- Chill pie fully to set filling for clean slices.
- Whip cream just before serving for the best texture; chill the bowl for faster whipping.
- Zest limes before juicing for easier handling.
- Enhance aesthetic: Serve on a white ceramic pie plate, garnish with whipped cream swirls and lime zest for a tropical look.
Variations and Customization
- Gluten-Free Key Lime Pie: Use gluten-free graham crackers or almond flour crust.
- Vegan Key Lime Pie: Use coconut condensed milk, 3 tbsp aquafaba for yolks, vegan butter, and coconut whipped cream.
- Low-Sugar Key Lime Pie: Use sugar-free condensed milk and 2 tbsp stevia in the crust; reduce powdered sugar in the whipped cream.
- Lemon-Lime Pie: Replace half key lime juice with lemon juice; add lemon zest.
- Coconut Key Lime Pie: Add 1/4 cup toasted coconut to the crust; use coconut cream for the topping.
- No-Bake Key Lime Pie: Skip baking filling; chill for 6 hours to set.
- Chocolate Key Lime Pie: Add a layer of 1/2 cup melted dark chocolate over the baked crust before filling.
- Mini Key Lime Pies: Use muffin tins with liners; reduce bake time to 10-12 minutes.
