Looking for the PERFECT Key Lime Pie? You’ve found it! It has just the right amount of lime goodness, the texture is smooth and creamy and it tastes amazing!
Why You’ll Love This Recipe!
I am craving summer. And nothing says summer to me like a key lime pie. This delicious pie is like a Caribbean vacation for your mouth. The tart key lime flavor and the smooth custard is pretty amazing. I truly believe this is the perfect recipe and it is the next best thing to being in the Florida Keys!
What is a Key Lime?
The difference between a key lime and a Persian lime (the limes usually found in the grocery store) is mainly the size, color and a slight flavor difference. A key lime is smaller, a little more yellow in color and slightly tarter in flavor. Because they are not readily available in my grocery stores, I always use Nellie & Joe’s key lime juice, which works perfectly every time. The key lime juice is usually found in the juice aisle of the grocery store. Be sure and use key lime juice rather than the juice of a regular Persian lime for this easy key lime pie recipe.
Ingredients Needed
- Graham crackers crumbs
- Sugar
- Butter. I use salted butter
- Sweetened condensed milk
- Sour cream. Could substitute plain Greek Yogurt.
- Key lime juice
- Lime zest and Whipped Cream for garnish
How to Make Key Lime Pie
Graham Cracker Crust
- You can buy a pre made crust at the store, but a homemade graham cracker crust is so much better and so easy to make. All you need is graham cracker crumbs, melted butter, and sugar. You can find my post on how to make a graham cracker crust here. It is the perfect base for this pie!
- Combine crumbs, sugar and butter. Mix until blended
- Press crumbs into bottom and sides of a 9-inch pie plate.
- Bake the crust at 350 degrees F. for 10 minutes or until golden brown on the edges.
- While the crust is baking, whisk together your key lime juice, sweetened condensed milk and sour cream. Stir until it is completely combined and smooth.
- Pour the key lime mixture into your graham cracker crust. You don’t have to wait for the crust to cool before filling it because it’s going right back into the oven.
- Bake for 10 minutes. Watch for little bubbles to form just underneath the surface of the pie, turn off the oven and let it sit in the warm oven for another 30 minutes. Just make sure to remove it before the pie starts to turn brown.
- Allow it to cool after removing it from the oven and then chill it in the refrigerator overnight to allow it to set up. The waiting is the hardest par!! But I promise, it’s worth the wait.
- Top the pie with whipped cream. Follow my directions for making perfect whipped cream here using a stand mixer and a whisk attachment. I don’t sweeten the whipped cream because the pie is so sweet. I do add the vanilla to the whipped cream though.
- Put the whipped cream in a piping bag with a large start tip to get the great border on my pie above. Then sprinkle a little key lime zest onto the whipped cream, add a lime slice as a garnish and you’ve got perfection.
Frequently Asked Questions
Does Key Lime Pie need to be refrigerated?
Keep uneaten pie in the refrigerator. The pie will last 3-4 days in the refrigerator and freezes well when stored airtight for 1-2 months.
Can I use regular limes instead of key limes?
You can but there will be a slight difference in flavor. I always use key lime juice.

How would you make this DAIRY FREE? A couple of my children have food intolerances/allergies. My husband bought me an Edward’s Key Lime Pie from Brookshire’s (saw a comment that said yours was better than Edward’s when I googled for a copykat) and they are just drooling over it…plus it’s my new favorite dessert, especially when topped with fresh cut strawberries and a thin strip of bacon! YUM!!! I have found a recipe for dairy free sweetened condensed milk that I think might work, but what is the sour cream used for in this recipe? If you know of a good dairy free sub then you save me a step. However, knowing what it is used for will help me to find a substitute of the same nature that will provide the same property in the recipe. I’m assuming the sour creme is for texture? It may help to know that they can’t do soy either, so no tofu. -Also no wheat products…but they are usually easily subbed in these types of recipes as they are minimal. Thanks in advance! My children are anxiously anticipating this treat. I can’t wait to share it with the two who couldn’t indulge on the regular one (made with dairy ingredients).

Nancy, I’m not much help here as far as non dairy substitutes.. Sounds like maybe you will just need to experiment. Good luck
Roberta Gabor says
where would I find Key limes. Can you use regular Limes?
Leigh Anne says
You can find bottled key lime juice in the juice aisle of the grocery store if you cant find actual key limes in the produce section

This turned out great. Thank you for sharing.
Laura says
Hi, this is the perfect pie!! I wondered is there a way to prevent the crust from crumbling when cutting slices? Could I bake it a bit first?
Thank you,
L.
Leigh Anne says
Laura, I am so glad you loved the pie too. I apologize but somehow the bake the crust for 10 minutes part got left of the recipe instructions. It is in the body of the blog post but not the recipe below. I have updated the recipe to read correctly. Thanks
