Key Lime Pie Recipe – The Best Authentic Florida Key Lime Pie Recipe

key lime pie on a plate

This is the best, most authentic Florida Key Lime Pie Recipe…not too tart, not too sweet, just a perfect slice of paradise.

Key Lime Pie filling has just 3 basic ingredients – key lime juice, sweetened condensed milk and eggs. So, why are some Key Lime Pies so much better than others?

The best Key Lime Pies use real, fresh-squeezed key lime juice. Do not use bottled key lime juice. Do not use an ordinary lime, and don’t even touch that little green plastic bottle of lime juice, or you will be disappointed. Key Limes are more tart and acidic than ordinary limes, and that’s the “key” to getting a filling that’s not too tart and not too sweet.

A visit to Florida is not complete without a slice of our state dessert! 

Key Lime Pie Recipe – The Best Authentic Florida Key Lime Pie Recipe


  • 1 1/2 cups graham cracker crumbs
  • 1/4 cup sugar
  • 1/2 teaspoon cinnamon
  • 1/2 cup butter, melted
  • 1, 14 oz can sweetened condensed milk
  • 3 egg yolks
  • 1/2 cup fresh squeezed Key lime juice or Nellie & Joe’s bottled Key lime juice
  • whipped cream for serving and lime slices for garnish


  1. Combine graham cracker crumbs, sugar and cinnamon in a bowl and mix together until well combined.
  2. Add melted butter and stir until the mixture resembles wet sand.
  3. Press into a 9-inch pie pan and bake 6 – 8 minutes at 350º.
  4. Remove from oven and cool.
  5. Combine sweetened condensed milk and egg yolks in a large mixing bowl blending until smooth with a whisk.
  6. Add Key lime juice and whisk until smooth.
  7. Pour filling into the pie crust and bake at 350º for 10 minutes.
  8. Cool on wire rack for 1 hour.
  9. Transfer to the refrigerator to chill for at least 4 hours or overnight.
  10. When serving, top with whipped cream and garnish with lime slices.


Once you taste a homemade graham cracker crust, you’ll never go back to buying a ready-made crust…I promise! If you’re in a hurry, I give you permission to use a store bought graham cracker crust, but next time try homemade.

Enjoy a slice of paradise, enjoy a real Florida Key Lime Pie.
