This easy key lime pie recipe is by far one of my favorite desserts to make. The refreshing and bright key lime filling sits so perfectly on top of the buttery, crisp graham cracker crust. This recipe is so easy, you will want to make it again and again! Whipped cream is a must for topping. You can use canned whipped cream, of course, but why would you when it’s SO easy to make your own homemade whipped cream. I’ve included the recipe for my easy-1 minute-2 ingredient-homemade whipped cream below. 😊

Graham Cracker Crust:

My favorite, buttery graham cracker crust is the perfect vessel for key lime pie. 

Graham cracker crumbs + melted butter + sugar = 😍

The Key Lime Filling: 

  • Key lime juice: Key limes are smaller than regular limes and their flavor is sweeter and more tart. Nellie and Joe’s is a great brand of bottled key lime juice that will save you a billion years of juicing a thousand little limes. Find it in the juice aisle near the lemon and lime juices. 
  • Sweetened condensed milk: A classic key lime pie ingredient. Creamy, rich, and indulgent, perfect for balancing out the tartness of the key lime juice. 
  • Egg yolks: The protein of the yolks combine with the acidity of the lime juice and cause the pie to thicken during baking. You can always make a meringue with the leftover whites which makes for a delicious topping!

For Topping:

Whipped cream is mandatory for topping key lime pie!!

This is my recipe for EASY(!!) homemade whipped cream. Just 2 ingredients, 1 minute, and way better than store-bought:

  1. Add ¼ cup heavy cream and 2 tablespoons of sugar to a large bowl. (Optional: a dash of salt and a teaspoon of vanilla)
  2. Use an electric mixer to beat on high speed for about a minute until thick and creamy.
