Why You’ll Love This Recipe

If you love key lime pie you’re in the right place! Traditional Key Lime Pie is baked and has a filling that is a bit like lime curd. While it’s delicious, I love the creamy no bake version even more for so many reasons:

You don’t need to heat up you house by turning on the oven.
This pie filling has the creamiest texture with the best key lime flavor from zest and juice.
You can start with a store-bought crust or make mine from scratch.

Ingredients Needed

Graham Cracker Crust: Make mine or buy yours from the store! My graham cracker pie crust starts with graham cracker crumbs, sugar, and melted butter and tastes amazing.
Key Lime Juice: The acidity of the lime juice helps to set the pie – and because this is a key lime pie, you’ll want to use key lime juice.
Lime Zest: Check out my How to Zest a Lemon tutorial for tips. Lime zest gives SO much flavor, so don’t skip it.
Cream Cheese: Make sure it’s softened to avoid lumps in the creamy filling.
Whipped Cream: Make my delicious homemade recipe! This light and fluffy whipped cream will be pipped around the edges.

Key Limes vs Regular Limes

There is a difference between regular limes and key limes. Persian limes are larger and have a more acidic taste, whereas key limes are more floral and sweet and smaller in size.

You can use regular limes for zesting, but be sure to use key lime juice for the filling (bottled or fresh).

How to make Key Lime Pie

Expert Tips

With cream cheese, it is so important to let the cream cheese be at room temperature when you start using it to avoid a lumpy pie.
When making fresh whipped cream, be sure to use heavy whipping cream (also called heavy cream) and beat it until stiff peaks form. You can also substitute cool whip for garnish if you prefer.
Make my homemade graham cracker crust, or buy one from the store, but use a 9-inch pie plate so the filling fills it up. You could also use a Golden Oreo cookie crust or shortbread crust.
Store the pie in the fridge or place leftovers in the freezer.
