The best Key Lime Pie and you only need 4 ingredients!
The best Key Lime Pie and you only need 4 ingredients!Key Lime Pie is one of my favorites because there's no easier pie (seriously, any beginner cook can make this and look like a pro doing it), and it's absolutely delicious! The base of the pie is a graham cracker crust–you can use store-bought but homemade is just 3 ingredients and tastes way better.

OMG THIS WAS A REALLY GOOD RECIPE! WILL DEFINITELY MAKE AGAIN A REAL KEEPER. BUT NEXT TIME I WILL SPRAY MY PIE PAN CAUSE IT GOT STUCK. BUT OVERALL A GOOD RECIPE. DEFINITELY DOING AGAIN👍😊
Love the pie crust from scratch. Also I really prefer the recipe from the label on Nelly and Joe’s Key Lime Juice product. You can find it on-line if you prefer a key lime pie, not as sweet, and more like the original key lime pies from the Florida Keys. The change in recipe is…the pie only takes 1/2 C juice, one can of sweetened condensed milk , no cream cheese, but does use 4 eggs yolks (the yolks make it setup), cook 15 minutes.
My father in law , loves the key lime pie posted from Tastes Better from Scratch, with the cream cheese, so I think it just depends on the personal preference. Both are really really great pie’s!!
Buen Provecho
Absolutely the best key lime pie I’ve ever had. Easy to make. Nelli’s Lime juice gives it amazing flavor!😉
If I make this recipe into smaller individual pies, do I have to change the baking time
Would love to make this pie but I live in Toronto, Canada and I have yet to find Key Lime Juice….just regular lime juice. Will this make a great difference?
PS When in Florida this winter I will certainly stock up on this item!!
You could get it online! https://www.amazon.ca/Nellie-Joes-West-Juice-Plastic/dp/B000SRK7Q2/ref=sr_1_3?crid=2TZKHPM5UJIHN&keywords=nellie+key+lime&qid=1662039651&sprefix=nellie+key+lime%2Caps%2C114&sr=8-3
Interesting recipe, all the other ones I have read call for eggs. Will try yours & send comment.
Can I use ” whipped ” cream cheese ?????
Thanks for giving it a try. Make sure to use the brick of cream cheese NOT the whipped kind!
I know you posted this question a year ago but for future reference, whipped cream cheese will change the texture of your pie to some degree and you would need to use more than what the recipe calls for because whipped has more air in it so it’s less density. I would suggest trying 6 oz instead of four and see how it goes
This pie was so easy to make and was a real crowd pleaser! I will definitely be making this again, so light and refreshing with the perfect amount of tartness.
I’m sorry to say that this key lime pie was very, very sweet. So sweet that we couldn’t eat it. I’ve not had an official key lime pie in Florida so I cannot compare it to the real thing. My husband loves key lime pie and liked the lovely lime flavour but it was sickly sweet. We’ve enjoyed so many of your recipes but this one is not for me.
Best Key Lime Pie EVER! Always a holiday favorite at our house!
This pie is perfection! Everyone loved it!
