If you love key lime pie then you will adore this Key Lime Cheesecake Pie. It’s absolutely the best way to enjoy key limes. The balance between sweet and tart is perfectly blended into a tangy cheesecake filling. The filling rests on a crisp graham cracker crust and is topped with homemade whipped cream. This recipe is quite simple and will be wonderful on a hot summer day.
I love making sweet and tangy desserts. Not too long ago I made easy lemon cheesecake bars. And when I’m in the mood for lime, I turn to my old trusted recipe for lime pie. It’s this pie that inspired me to dig through the blog archives and revamp my very old recipe for key lime pie.
This is no ordinary key lime pie though. The filling is cheesecake based and the combination of sweetened cream cheese and key lime is absolutely phenomenal. It’s my preferred key lime recipe. One that I make summer after summer. One that I proudly bake for friends.
The original recipe was posted in January of 2014. Soooo long ago! It made enough for two pies and I cheated with store-bought graham cracker crusts.
Today I bring you an updated version of my favorite key lime cheesecake pie and it’s absolutely the best you’ll ever taste.
The base of the pie is a simple graham cracker crust made at home. It’s very important you make your own crust. They just taste so much better!
Crush some graham crackers in a food processor. Or you can put them in a resealable bag and pound them to pieces. Mix in a little sugar and melted butter and you have the base for your pie.

I love to use fresh key limes. I think it makes all the difference in taste. While it is tedious to juice these tiny limes, it’s so worth it in the end.
It may be difficult for some of you to find key limes. If that’s the case, you may have no choice but to use the bottled stuff. But, double check the label to make sure it’s actual key lime juice. Regular lime juice won’t be as sweet and flavorful.

Key Lime Cheesecake Filling
The filling for this cheesecake pie is just like the one I used for the lemon bars mentioned above. It’s the exact same, only with key lime instead of lemon. Keep in mind this is not a traditional key lime pie. There are no massive amounts of sweetened condensed milk in this recipe.
There’s actually not a ton of sugar in the pie at all. Just a little over one cup. There’s more sugar than that in cookies!
You need just 6 simple ingredients today
- cream cheese
- key lime juice
- key lime zest
- vanilla extract
Prebake the crust before adding the filling. This will make it extra firm and crunchy. So wonderful with the creamy texture of the cheesecake.
Once you add the filling, the pie needs to bake for 30-35 minutes. And because the cheesecake filling is super creamy, the pie will need to cool to room temperature and then chill in the refrigerator for at least 8 hours.
I know that’s the last thing you wanted to hear. The wait is agony!
Top the pie with homemade whipped cream just before you plan to serve it. Enjoy!
