Today is Josh’s birthday! Happy Birthday Josh! To celebrate, I made him a Key Lime Pie with Coconut Macaroon Crust. We celebrated yesterday so I could share Josh’s birthday dessert with you today! I didn’t have to twist his arm to eat pie a day early:)

Josh isn’t a huge dessert fan, I know, what is wrong with him? 🙂 He loves lime desserts though. I am always trying to come up with new lime recipes for him. A few of his favorites include: Key Lime Pie, Key Lime Tart, Coconut Lime Cupcakes, Lime Bars, and Lime Coconut Snowballs. He is a lime lover!

I wanted to mix things up this year so I created a coconut macaroon crust to go with his favorite key lime pie filling! Josh loves coconut too so I knew he would love my twist on the traditional key lime pie. And you really can’t go wrong with the coconut and lime combo! They are a match made in heaven!

To get the pie party started, I used my favorite coconut macaroon recipe. Instead of making cookies, I pressed the coconut mixture into a pie pan! I wasn’t sure it would work, but my fingers were crossed:) I partially baked the crust so it would set up a bit before putting in my filling.

Next, I whisked up a tart key lime filling to go inside my sweet coconut macaroon crust. I baked the pie and pulled it out! It looked perfect! The crust was light golden brown and the key lime filling was smooth and set!

I let the pie chill in the fridge for about an hour and then it was time to slice the pie…and see if my new creation worked:) The pie sliced beautifully! I gave the first slice to the birthday boy and he didn’t hesitate to dig in with his fork. He loved the pie! Yahoo! My new lime dessert was a success!

I enjoyed a piece too! I will warn you, this pie is super sweet, so cut small pieces…or enjoy a big piece and go into a sugar coma. Josh didn’t seem to mind his big piece:)

Key Lime Pie with Coconut Macaroon Crust is a fun twist on the classic pie! It is fun to mix things up every once in awhile! We love this pie and I think you will too! Enjoy!

For the Coconut Macaroon Crust:

  • 2/3 cup sweetened condensed milk
  • 1 large egg white
  • 1 1/2 teaspoons vanilla
  • 1/8 teaspoon salt
  • 3 1/2 cups sweetened coconut

For the Key Lime Filling:

  • 1 14-ounce can sweetened condensed milk
  • 4 large egg yolks
  • Zest of 1 large lime
  • 1/2 cup lime juice


  • Preheat the oven to 350°F. Spray a 9-inch pie pan with non-stick cooking spray. Set aside.
  • First, make the crust. In a large bowl, stir together the sweetened condensed milk, egg white, vanilla extract, and salt. Stir until combined. Add in the coconut and mix well. Press coconut mixture into prepared pie pan. Make sure you press the mixture up the sides to form a nice pie crust. Bake for 10-12 minutes. Remove from oven and let cool.
  • To make the key lime pie filling, in a medium bowl, whisk together the sweetened condensed milk and egg yolks. Whisk until well combined. Add in the lime zest, and lime juice. Whisk until smooth. Pour filling over the coconut macaroon crust.
  • Bake for 15-17 minutes, or until filing is set and the coconut crust is golden brown around the edges. Remove from oven and cool on a cooling rack. When cool, chill the pie in the refrigerator. The filling will set up as it cools. Chill for at least one hour before serving.
  • Note-if you can’t find key limes you can use regular limes for the juice. You can also use bottled key lime juice if you wish.

  1. Can’t wait to try this! Do you think the crust would work with unsweetened coconut to cut the “too sweet” taste?

  2. Today is my birthday and I’m making this for myself since my wife doesn’t like coconut. Can’t wait tot try it!

  3. Why no key limes? This is a Persian lime pie. Very different taste, but it looks good. I’d just change the name.

  4. I was looking for a lime pie recipe for the 4th, and came across yours. looks sooo good I’m giving tit a try

  5. I just had to report back after making this for my key lime-loving mother in law’s birthday gathering. It was absolutely OUT. STAND. ING!! Thanks for the unique and delicious twist on a family favorite, Maria! 🙂

  6. Love the simple idea of this recipe. However it seems that macaroons were forgotten in the actual instructions. So I cut the sweet milk in the crust and used regular milk. Then used unsweetened coconut. Glad I did since even doing this it was a super sweet pie. The consistency was great. I will try coconut milk all around next time and more lime.

  7. How “done” should the bottom of the crust look? I just made it and the sides have the browning on top, but the bottom looks a little gooey….should I leave in the oven longer?

  8. I never comment on recipes but I will for this one. This is absolutely amazing!!! Made it for colleagues and received rave reviews. Will make again. Delish! 10/10

  9. I’ve made a few recipes from your site with success, but feel this one was a flop. No offense, but it’s annoying all these reviews read “this looks soooo good” without any actual review by readers making it.

    The coconut macaroon crust baked up without any real change in consistently from when it was pressed into the pan (except the top did get a nice crunch to it). The taste was also impeded by the constant chewing of coconut shreds.

    The filling definitely didn’t call for enough lime flavor so it fell flat there.

    It was basically a sweetened
    condensed milk pie with coconut shreds.

  10. Hi – this looks great!

    I’m a bit confused about you adding the condensed milk twice though? (Step 2 and Step 3). Is that a mistake?

  11. I wonder if you used coconut milk instead of condensed milk if it would still work – it would cut some of the super sweet taste? I love this idea though. Just made a key lime pie with graham cracker crust today for Easter so it will have to be next time.  Thanks for the great ideas! 

    1. Condensed milk is thicker and creamier,regular coconut milk might not be thick enough.

  12. I am on a strict dialysis diet, what are the nutritional facts?
    Particularly sodium, phosphorus, and potassium content.

  13. 4 stars
    I really was craving a citrusy hit when this recipe came across my FB feed. Luckily I had a couple tins of condensed milk in the cupboard and a bag of coconut in the freezer. 
    While I was really happy with all the flavours, I have one comment – for me, there was just a touch  too little filling for that amount of crust. Possibly double (or at least 1.5x) the filling would do the trick. 
    We don’t get sweetened coconut here in South Africa, so I didn’t find the pie too sweet.  I’ll definitely make it again! 

  14. If I want to cut back on the sweetness,  can I use 1/2 unsweetened coconut milk and 1/2 sweetened condensed milk?  

  15. I really like this recipe though compared to others I have seen.  I like your other recipes and your style of cooking!

  16. Has anyone attempted to freeze it. I am considering it for some desserts at a casual outdoor wedding reception, and will need to bake a few days before. Can it freeze and thaw?

  17. Excellent,  key Lime Pie.  I can see why it is your hubby’s favorite, and so easy to make.  I will try a Lemon Pie if you have one.  Thank you and continue cooking.  God Bless you and your beautiful family.
