Ingredients

Scale

For the Graham Cracker Crust

  • 18 Graham Cracker Sheets
  • 3 tbsp Brown Sugar
  • 1/2 tsp Cinnamon
  • 10 tbsps (141 g) Salted Butter, melted

For the Filling

  • 5 (90 g) Egg Yolks
  • 2 cans Sweetened Condensed Milk
  • 1/4 cup (60 g) Sour Cream
  • 1 cup (240 ml) Key Lime Juice
  • 1/2 tsp Vanilla Extract

For the Topping

  • 1 cup (240 ml) Heavy Cream, cold
  • 1/4 cup (30 g) Confectioners Sugar
  • 1/2 tsp Vanilla Extract
  • 2 tbsps Fresh Mint, chopped (optional)
  • Key Lime Zest or Lime Zest for garnish (optional)

Instructions

  1. Prepare the Crust: Preheat the oven to 350°F. Combine graham crackers, brown sugar, cinnamon, and a pinch of salt in a food processor and blend until fine crumbs form. Add melted butter and blend until the mixture resembles wet sand.
  2. Shape and Bake Crust: Press the graham cracker crumb mixture firmly into the bottom and sides of a springform pan to create a sturdy crust. Bake for 12 minutes, then remove and set aside to cool.
  3. Make the Filling: In a large bowl, beat egg yolks with an electric mixer for 3 minutes until bubbly and pale. Add sweetened condensed milk and sour cream; mix briefly to combine. Slowly pour in key lime juice and vanilla extract while mixing until blended.
  4. Bake the Pie: Pour the filling into the pre-baked crust. Bake for 15 minutes until the filling is just set with a slight jiggle in the center. Remove from oven and let cool on the counter for 30 minutes, then refrigerate for at least 3 hours to chill and set.
  5. Prepare Whipped Cream Topping: Using an electric hand mixer, whip cold heavy cream, confectioners sugar, and vanilla extract on medium-high until stiff peaks form. Spread or pipe onto the chilled pie.
  6. Garnish and Serve: Run a butter knife around the edge to loosen crust from pan. Garnish with lime zest, fresh mint, and lime wedges if desired. Slice and serve chilled.

Notes

  • Do Not Overbake: Bake the pie until the filling is just set and still slightly jiggly in the center to avoid cracks.
  • Let it Chill: Chill the pie thoroughly in the refrigerator for at least 3 hours or preferably overnight to allow flavors to meld.
  • Use Fresh Key Limes: For the best authentic flavor, use fresh key lime juice. Bottled juice can be used if fresh is unavailable.
