For the Graham Cracker Crust:

  • 1 and ½ cups graham cracker crumbs about 10 sheets
  • 6 tbsp. butter melted and slightly cooled
  • ½ cup sugar

For the Key Lime Filling:

  • 2 14 oz. cans sweetened condensed milk
  • 5 large egg yolks
  • ¾ cup key lime juice

For the Homemade Whipped Cream

  • ¼ cup heavy whipping cream
  • 2 tbsp. sugar
  • dash salt optional
  • 1 tsp. vanilla extract optional


  • Preheat oven to 350°
  • Spray a 9.5" pie pan with non-stick cooking spray.

Make the Graham Cracker Crust

  • Use a food processor to grind the graham crackers into crumbs.
  • In a medium bowl, combine the graham cracker crumbs, sugar, and melted butter.
  • Use the flat bottom of a measuring cup to evenly press the crust into the bottom of the greased pie pan and up the sides slightly.
  • Bake the pie crust in the preheated oven for 10 minutes. Remove from the oven and let cool. Do not turn the oven off.

Make the Key Lime Filling:

  • Whisk the egg yolks, sweetened condensed milk, and key lime juice together until smooth.
  • Pour into the cooled pie crust and bake for 15 minutes. The filling should be mostly set.
  • Allow the pie to cool on the counter until it's not too hot for you to pick it up with your hands, about 10 minutes.
  • Move the pie to the refrigerator and allow it to cool completely for about 2 hours before serving.

Make the Whipped Cream:

  • In a large bowl, combine heavy whipping cream, sugar, and, if using, salt, and vanilla.
  • Beat on high with an electric hand mixer until thick and creamy. About 1 minute.
