Ingredients

Graham cracker crust

  • 1 1/2 cups graham cracker crumbs from about 13 whole (rectangle) graham crackers
  • 3 Tbsp granulated sugar
  • 6 Tbsp unsalted butter melted

Key lime pie filling

  • 2 (14 oz each) cans sweetened condensed milk
  • 2 large egg yolks
  • 1/2 cup sour cream full fat is recommended
  • 3/4 cup fresh key lime juice can be substituted with regular lime juice
  • 2 tsp key lime zest
  • 1/8 tsp kosher salt

Garnishes

  • additional lime zest
  • key lime slices
  • whipped cream

Instructions

Prepare

  • Preheat oven to 350°F. Set out a 9" pie pan/pie dish.

Make crust

  • Combine crust ingredients (graham cracker crumbs, sugar, and butter) in a mixing bowl and stir to combine well.
  • Transfer mixture to 9” pie pan and press evenly into the bottom and sides of pan.
  • Bake the crust for 9 minutes, then set aside.

Make filling

  • While crust is baking, make the pie filling by adding the sweetened condensed milk, egg yolks, sour cream, key lime juice, lime zest, and salt to a mixing bowl.
  • Use hand mixer to beat together for about 2 minutes, scraping the sides of the bowl as needed.
  • Tap bowl gently on a counter a couple of times to release any air bubbles from the mixing.
  • Pour filling into baked crust, spreading into an even layer.

Bake

  • Bake in the 350°F oven for 15-20 minutes, until the center is just slightly jiggly when nudged, then remove and let sit at room temperature to cool completely.

Chill

  • Once cooled, cover loosely with plastic wrap and refrigerate at least 2-3 hours, or up to overnight.

Serve

  • To serve, add swirls of whipped cream around the outside edge of the pie, and sprinkle the whipped cream with a bit of lime zest, with halved key lime slices arranged in a fan shape in the center of the pie.

Notes

  1. Recipe makes one 9" pie, with the suggested serving being 1/8th of the pie.
  2. I highly recommend using freshly squeezed lime juice for this recipe.
  3. If key limes aren't available, you can substitute with regular limes.
