On Monday I shared a Sour Cream Lemon Pie, so I figured I better share this Key Lime Pie Recipe for all the lime fans out there.

It’s delicious, refreshing, and totally easy to make.

Ultra Silky Key Lime Pie Recipe

The other day I was casually relaxing on the couch (playing Candy Crush of course), when my youngest daughter walks up to me with a long piece of dry spaghetti in her chubby little hand. Oh boy,  she got into the pantry and is so hungry she has resorted to eating dry pasta. I tell her to go put it in the trash (still relaxing on the couch, still playing Candy Crush), and she toddles off.

A minute later she was back with another piece of dry pasta for me. I chuckled and, like any respectable parent, I took a picture and posted it to Instagram.

Then after looking at the picture I realized my windows were filthy, so I got up and cleaned them.

I have issues.

Don’t worry, I got my daughter a suitable snack too.

But seriously, my kids are starting to eat me out of house and home. They are constantly wanting a snack, or a popsicle, or dry pasta.

My oldest daughter can now eat an adult size portion of dinner, and then some. Just last night she requested a “grown-up” plate for dinner rather than the cute florescent plastic plates for the kids. What’s next?! Training bras? Heaven help me.

One thing I know she’ll never grow out of is dessert. After all, she’s still my daughter.

This delicious Key Lime Pie Recipe was so silky in texture, tangy, and sweet. If you can’t get ahold of key limes then try substituting with a mixture of fresh lemon and lime juice (half lemon, half lime). It’s the perfect summer pie to brighten your day!

    Hi! I’m dying to try this! But sour cream is very difficult to find in Portugal, could I use creme fraiche instead? Looks delicious!

    1. Hi Lustufa! You could definitely try a creme fraiche, but I would try a plain greek yogurt first if you can get your hands on that! 🙂 Hope you enjoy it!

    I made this pie today but unfortunately, living in Canada, I do not have access to key limes. I used your suggestion of adding some lemon juice to lime juice and the results were great. A very silky and tangy pie that I will make again!

    I followed the recipe. Used bottled lime juice and it tasted awesome! However it wasn’t firm as I want it. Is there any advice you can give me for a FIRM, tasty key lime pie?

    I was so thrilled to find bottled key lime juice. But Wow, the pie was tart. Any tips for bottled juice? Dilute it or use less? The pie was silky and beautiful otherwise.

    1. Key Lime juice is definitely on the tart side, if you want to tame the tart you could try to make a simple syrup with the key lime juice. In a small saucepan heat the lime juice with about 1/4 cup of sugar and stir until dissolved. Let it cool completely then measure out the 3/4 cups needed and continue with the recipe. Hope that helps!

    Hi Shawn,
    I wanted to try this lovely pie, but before I start, can you tell me approx. how big the pan or form you have used for it is? 🙂

    Your pie looks gorgeous! I tried but somehow it didn’t harden in the oven (like it’s all watery in after 15 mins). It is suppose to harden up after chilling? Thanks a lot!

    1. Hi Michelle! Yes, the pie will still be quite soft when you take it out of the oven. Just make sure you see some tiny bubbles come to the surface before you remove it from the oven. Then let it cool at room temp, then in the fridge for 3 or more hours. The pie should be thickened by then, like a silky pudding. 🙂 hope that helps!

    i LOVE key lime pie! i’ve been craving it ever since my son was born 3 months ago. i don’t have time during the day to bake anything but as soon as my hubby comes home he gets to babysit while i make yet another key lime pie.. if it weren’t for the calories… but a breastfeeding mother needs some extra, right?!

    1. Ah thanks Emily! I love these photos too, I am particularly proud of the first one. I think it could be a magazine cover…just sayin. Lol 😉

  8. We are on the same wavelength! Both of your pies sounds fabulous…seriously perfect for the warm summer. And don’t worry, console yourself knowing your kids aren’t the only ones having to fend for themselves. 🙂

  9. I totally hear ya with the oldest daughter thing. My oldest daughter is 9 (EEEK) and she almost always gets an adult plate now and if we give her a smaller one, she complains, lol! And I know, training bras are right around the corner for us. We’ve already had to have the Aunt Flo talk because she was asking questions. Oh questions….! This pie looks amazing! My parents are huge Key Lime lovers so I’ll have to make this for them some time 🙂

    This sounds awesome!! I love making pies but I’m sorry to admit I’ve never tried to make a key lime pie. :(. Now that I know I have a recipe from a fabulous source, I’m going for it! How many key limes do you suppose are needed for 3/4 cup?
