Ingredients Notes & Substitutions
Please check the recipe card at the bottom of the post for exact quantities and detailed instructions (scroll down).
For the Crust:
You can totally use a store-bought crust. If you decided to make your own crust, this is what you need:
- Graham cracker crumbs
- Sugar: I used regular white sugar, also known as caster sugar. Feel free to use brown sugar if you prefer.
- Cinnamon: This is optional, but it adds a nice extra layer of flavor.
- Salt: I prefer kosher or sea salt. If you only have table salt handy, I recommend reducing the amount to half.
- Butter: I prefer to use unsalted butter, but if you only have salted butter handy, you can use it. In this case, skip the salt called in the recipe.
For the Filling:
- Cornstarch + Water: This will help the pie to set and be creamy and smooth.
- Sweetened Condensed Milk: Be sure is the full-fat version.
- Sour cream: You can substitute plain yogurt for plain sour cream. I recommend using the full-fat versions.
- Key Limes: You will need the zest and juice. Be sure to zest the limes before you squeeze the juice from them, as it’s near impossible to do afterward. If you are using bottled key lime juice, you can use the zest of regular limes.

1 – Make the Crust
- Preheat oven to 350º F (160º C).
- Mix graham cracker crumbs, sugar, cinnamon (if using), salt, and butter in a small bowl.
- Place the crumb mixture into an 8″ – 9.5″ pie pan. Press the crumbs firmly in the bottom of the pan and a little bit up the sides of the pan.
PRO TIP: I like to use a measuring cup to press the crumbs into place. It’s up to you if you want to go all the way up the sides of the pan or not.
- Bake for 8 -9 minutes. Remove from the oven and let it cool (about 20-25 minutes).
PRO TIP: I usually let the crust cool over the counter for 8-10 minutes and then pop it into the freezer while I make the filling.
2 – Prepare the Filling
- Mix cornstarch and cold water in a small bowl; mix well. Set aside.
- In a mixing bowl whisk together sweetened condensed milk, sour cream, and lime zest. Then mix in lime juice and cornstarch mixture until well blended.
- Set mixture aside to rest for about 5 minutes, this allows it time to thicken before pouring into the crust.
3 – Bake
- Pour filling into cooled pie crust and evenly spread.
- Bake in the preheated oven until or until barely set, 15 – 18 minutes (pie should jiggle just slightly).
- Transfer to a rack and let cool completely, then refrigerate overnight.
How to Tell When the Key Lime Pie is Done
Bake the key lime pie until the filling is only slightly jiggly in the center (about 15-20 minutes). To check carefully slightly shake the pie pan and observe the center. It should only be *slightly* jiggly in the center. You want it mostly set. DO NOT touch it or your fingerprint will ruin the smooth and gorgeous top.
4 – Garnish and Serve
I like to add some fresh whipped cream, lime zest, and lime slices.
Frequently Asked Questions

Key limes are the preferred option when making Key lime pie, but if they are not available you can use regular limes. Both types of limes work perfectly in this recipe. To be honest, they taste very similar, in my opinion.

Extra Tips to Make Eggless Key Lime Pie
Let the pie chill overnight in the refrigerator so it sets up properly before serving.
If using fresh key lime you can simplify the lime juicing process by using a lime squeezer.
Use the piping bag to pipe perfect swirls or whipped cream.
If the pie is going to be at room temperature for an extended period of time, I recommend using stabilized whipped cream, since it will keep its shape for longer. I recommend garnishing your key lime pie just before serving.
