This easy, no-bake key lime pie is made with only four ingredients: egg yolks, sweetened condensed milk, lime juice, and graham cracker crust.

The reason this recipe works is that the acid in the lime juice coagulates the egg proteins and causes the filling to set while it chills.

If you can't get real key limes (or key lime juice, which you can sometimes find bottled or frozen) it's fine to use regular limes.


  • 4 egg yolks
  • 1 (14-ounce) can sweetened condensed milk
  • 5 ounces lime juice (key lime or otherwise)
  • 1 graham cracker pie shell (store-bought or homemade)
  • Optional: whipped cream

Steps to Make It

  1. Gather the ingredients.

  2. Beat the egg yolks.

  3. Stir in the condensed milk until well blended.

  4. Now stir in the lime juice and mix until incorporated.

  5. Pour the filling into your pie shell and refrigerate overnight.

  6. Serve topped with whipped cream.

  7. Enjoy!
