This classic key lime pie recipe is an old fashioned favorite that came straight from my Nannie’s family recipe box. She’s Southern and this key lime pie is easy to make homemade, right from scratch, like so many of her traditional recipes.
Key Lime Pie Ingredients
Ready to get started? You’ll love how easy it is!
- 14 ounces of sweetened condensed milk (1 small can)
- 1/2 cup lime juice
- 16 ounces Cool Whip
- graham cracker crust
I’ve also heard that some folks mix sour cream or make it with cream cheese. I don’t, but you could definitely experiment with that if you’d like to! Nannie sometimes serves this with meringue on top, but my gang loves it with extra Cool Whip.
How to Make
Begin by mixing the Cool Whip and sweetened condensed milk. Next, stir in the lime juice and mix well.
Pour into the graham cracker crust and spread evenly.
Refrigerate for a few hours or overnight before serving.
My boys love having extra Cool Whip and fresh lime zest on top before eating.
I think you’ll be ready to say it’s the best key lime pie recipe too after you try it.
How to store
IN THE FRIDGE: If you don’t eat it all immediately, just cover and pop it back in the fridge until you’re ready for more.
IN THE FREEZER: You can definitely pop this treat into the freezer. Just be sure to remove and let thaw a few minutes before slicing and serving.
Simple and no bake, this old fashioned key lime pie recipe comes together in a snap. It’s easy to see why this is a Southern classic with it’s sweet and rich flavor, plus smooth and creamy texture. It’s the perfect balance of sweet and tart.

You can definitely do that if you’d like. Enjoy! 🙂
