Summertime desserts have a few criteria: They have to be easy because no one wants to work extra hard during vacation season. They need to be refreshing, satisfying your sweet tooth without weighing you down or heating you up. And they simply can't require turning on the oven.

This easy, no-bake key lime pie is all of these things and more. It's made with only four ingredients: egg yolks, sweetened condensed milk, lime juice, and a premade graham cracker crust. How can a pie with eggs be no-bake, you ask? As the pie chills in the refrigerator, the acid in the lime juice coagulates the egg proteins, "cooking" them and causing the filling to set up. If you find using raw eggs unnerving or you are pregnant, use pasteurized egg yolks.

Key limes (also known as Mexican or West Indies limes) are a small and potent variety of lime with a distinct zesty flavor, and are best for this recipe. Unfortunately, they can sometimes be difficult to find. 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. Fresh juice is best, and adding some finely grated zest to this recipe will add even more lime flavor.


  • 4 large regular or pasteurized egg yolks

  • 1 (14-ounce) can sweetened condensed milk

  • 5 ounces freshly squeezed lime juice, preferably key lime

  • 1 store-bought or homemade graham cracker pie crust

  • Whipped cream, for serving, optional
