Easy Key Lime Pie

Josh can usually pass on dessert. He isn’t the biggest chocolate fan, but when key lime pie is on the menu, he will always have two pieces of pie! It is his all-time favorite dessert! I make him this easy key lime pie recipe every year for his birthday. It is his favorite pie and I am glad because it is SO easy to make. I usually don’t like to mess with pies because they can be tricky, but this one is super easy to make  and comes out perfect every time. You are going to love it!

How to Make Key Lime Pie

This easy key lime pie recipe has a sweet graham cracker crust, which is SO easy to make. For the crust you need, crushed graham crackers, sugar, and melted butter. That is it! Mix the ingredients together until moistened and press into a pie plate. Bake until the crust is golden brown and you have the perfect key lime pie pie crust!

For the rich key lime filling, you only need 4 ingredients:

  • lime zest
  • lime juice
  • egg yolks
  • sweetened condensed milk

You should be able to find key limes at most grocery stores, but if you can’t you can use the bottled key lime juice. We like this brand. It is really good and a major time saver. There is nothing wrong with shortcuts! You can also use regular lime juice if that is all you can find.

Mix the filling ingredients together and pour in the baked graham cracker crust. Bake until the filling is set, about 15-17 minutes and then let the pie cool completely. We like to chill it in the refrigerator before cutting to make sure it is completely set up before slicing. The pie is great served chilled or at room temperature.

You can serve the pie plain or you can add a dollop of whipped cream! You can also add a lime slice for garnish to make the pie extra pretty!

For the Filling:

  • 1 (14-ounce) can sweetened condensed milk
  • 4 large egg yolks
  • Zest of 1 large lime
  • 1/2 cup lime juice from 5 limes


  1. Preheat the oven to 350 degrees F. In a medium bowl, stir together the graham cracker crumbs, sugar, and melted butter with a fork. Mix until graham cracker crumbs are moist. Press mixture into a 9-inch pie plate or dish. Pat down the bottom and sides. Bake for 12 minutes or until golden brown.
  2. While the crust is baking, prepare filling. In a medium bowl, whisk together the sweetened condensed milk and egg yolks. Whisk until well combined. Add in the lime zest, and lime juice. Whisk well. Set mixture aside. It will thicken up as it sits.
  3. When the pie crust has cooled to slightly warm or room temperature, pour the lime filling over the pie crust. Bake for 15-17 minutes. Remove from oven and cool on a cooling rack. When cool, chill the pie in the refrigerator. The filling will set up as it cools. Chill for at least one hour before serving.

  1. This is the recipe I’ve been using for over 20 years and always get raves. A step-daughter requests it every time she visits. I sometimes use a regular crust and always top with real whipped cream!

  2. Any thoughts on how far ahead I can prepare this before serving?   Assuming it’s refrigerated is 48hrs too soon?!

  3. 5 stars
    The key lime pie recipe is a wonderful pie!  Not only does it taste good, it is really simple to make.  The only thing I would change is to garnish each piece with fresh made whipped cream (don’t tuin it by adding the frozen stuff!).  

  4. 4 stars
    The pie , out of the over looked fantastic! I can’t wait to chill , garnish and fast it. Will post again when it’s ready to eat. Thank you for this simple pie recipe.

  5. I made this recipe a few weeks ago using limes from my grandpa’s farm and it was lovely! Is there anywhere I can upload the photo?

  6. 5 stars
    Just made this and it tastes amazing. But mine is a bit runny. Not as firm filling as in your photos. what can I do next time to make sure it’s firm?

  7. I like its simplicity…I used regular crust and made a merangine…I had to improvise too hot to make a store run so I used what I have. It was a great way to use the whites..hate to waste food..its baking now.proof is in the pudding or should I say

  8. Hi there,

    Quick question. When you mention 1 1/4 cup of crumbs and 1/2 cup of lime juice, what’s the measurement like for “cup” in measurement like ml ? Is there an international measurement for “cup”?

    Sorry first time trying this receipt. 

    1. Key limes are harder to find so you can use regular limes. You just need 1/2 cup juice. You can even use store bought key lime juice.

    It’s very good — but I prefer to leave out the eggs and use 8 ounces of softened cream cheese instead. If you’re using bottled lime juice and have no limes of any kind, some grated lemon rind will still give you some added citrus sharpness. And, if you’re making the crust instead of using a store-bought one, try it with gingersnap crumbs. Ginger and lime go together beautifully!
