These key lime pie bars have an extra thick layer of filling and an easy homemade coconut cookie crust! Can be made with gluten-free, whole grain or all-purpose flours. For a grain-free version, check out these paleo no-bake key lime pies.
I posted these key lime pie bars over on My Baking Addiction last month but didn’t post them here just because they’re so unhealthy. But being as today is my birthday, I figured I could post these today and get away with it. :D
I thought that the world didn’t need another key lime pie bar recipe with a graham cracker crust so I went with something totally different.
So these bars have a coconut cookie crust! It’s super easy to make and you can use white whole wheat, 1-to-1 gluten-free baking flour or all-purpose flour.
I didn’t bother with a grain-free option because there are 2 cans of sweetened condensed milk in these bars. Whoops. I was assuming that someone who eats grain-free likely wouldn’t be interested in this filling recipe.
I’ve been working on paleo mini key lime pies so that recipe will hopefully be coming soon! Stay tuned. :) Update: here they are – paleo no-bake key lime pies!
There’s so much sweetened condensed milk in these bars because they have double the amount of filling that most key lime pie bars have. Key lime pie is tied with peanut butter pie for my favorite dessert ever and I didn’t want a dinky layer of filling.
The filling recipe comes from the comments of a recipe on Allrecipes. I’ve been making it for at least 10 years and I’ve never had a key lime pie I like better!
This recipe calls for a full cup of lime juice which requires a whole bunch of limes. With the cost of limes and the number of times I had to remake these bars to get the crust right, I switched over to lime juice that comes in a glass bottle after a while (not the kind in the green plastic lime-shaped bottle!).
You could notice a difference but it was actually much better than I thought it’d be! I’ll probably use half freshly squeezed and half bottled lime juice (if I have some around) in the future. Or even only 1/4 fresh.
They freeze well so if you’re worried about overloading on sugar, which is super easy with these bars, hide them away in the freezer. ;)
And for another fun key lime treat, try this key lime pie shot. These key lime pie ice cream bars are also gluten-free, as long as you use gluten-free graham cracker crumbs.
I hope you’ll enjoy the bars! If you try them out, I’d love for you to leave a comment below. Thanks!
Thick Key Lime Pie Bars with Coconut Cookie Crust (gluten-free, whole grain options)
- Prep Time:
- Cook Time:
- Ready in:
- Yield: 12 bars
Ingredients
- 2/3 cup unsweetened shredded coconut (not flaked coconut)
- 1 cup (125 grams) white whole wheat or 1 cup (125 grams) all-purpose flour or 1 cup 1-to-1 gluten-free baking flour
- 1/3 cup (67 grams) granulated sugar
- 1/4 teaspoon salt
- 1 teaspoon coconut extract
- 6 tablespoons (84 grams) unsalted butter
- 2 (14-ounce) cans sweetened condensed milk
- 4 large egg yolks
- 1 cup (240 milliliters) lime juice
- 1 1/2 teaspoons lime zest
- pinch of salt
For the crust:
For the filling:
Directions
- Preheat the oven to 350 °F (175 °C) and line an 8"x8" pan with a piece of parchment paper.
- Place the coconut on a baking sheet and bake for 4-6 minutes. Keep a close eye on it and stir as soon as you see it start to brown. Continue cooking for another minute or two until most of the coconut is lightly browned. Remove from the oven and cool completely.
- In a medium mixing bowl, stir together the toasted coconut, flour, sugar, and salt. Sprinkle the coconut extract over the top and use your hands to incorporate the butter until thoroughly combined. When pinched, it should hold together. You can alternatively pulse everything together in a food processor until well combined.
- Pat the dough firmly onto the bottom of the prepared pan and bake for 15 minutes or until lightly browned.
- While the crust is baking, prepare the filling. In a large mixing bowl, stir together all the filling ingredients until thoroughly combined.
- Remove the crust from the oven, let it sit for 2 minutes and then pour the filling over the crust. Bake for 15 minutes or just until set. Little pinholes or bubbles may form on the surface.
- Remove from the oven and let cool to room temperature, about 2 hours, before chilling in the refrigerator for another 2 hours before serving.
- Store in the refrigerator for up to 5 days.

The coconut crust sounds like it would be wonderful with the key lime flavor! Yummy!
It really is! Thanks. :)
Just curious, why did you omit the cream cheese that is often in key lime bars?These look delicious & will have to compare to my go to recipe that includes cream cheese.
Also, Overlandtraveler needs to lighten up. You were in no way offensive to anyone, she is clearly an overly sensitive person.
Hi there! I just googled key lime pie bars and only about half the recipes used cream cheese. I guess it’s just another variation I haven’t tried. :) I wanted these bars to be just like key lime pie and so they use the same filling recipe I use for pie. I hope you’ll like them if you try them! And thanks for not thinking I was offensive. I didn’t think I was but that comment did leave me a little confused. Thanks again!
Love the coconut crust! These look so good!
My younger son is a huge fan of anything key lime. Maybe we’ll have to make these bars together as a summertime treat.
I absolutely love key lime anything and I so want to try these! All in moderation, right? Sometimes it’s nice to have a treat! I think I will be treating myself to these soon!
Happy Belated Birthday!! These bars look perfect, and I mean like picture perfect! wow!
I love the look of that crust! I often use unsweetened coconut in my crust since my boys have tree nut allergies, it’s a perfect alternative for them and everyone loves the flavor. These look scrumptious!
Its look sooo delicious. Perfect dish!
thanks for sharing recipes with us here. Looking more from you dear
The texture looks perfect and I LOVE the addition of coconut to the crust!
These bars look seriously amazing! My family loves key lime pie, so these bars would be a smash hit! Great that they can be made with whole grain or gluten free flours, too – really versatile!
I love that you switched up the crust! These look like a great summer treat!
Everything in moderation except on your birthday!! Happy birthday!! I love these bars s much, what an amazing dessert. We all have to treat ourselves every now and then :)
My husband is going to love these!
I am LOVING that coconut cookie crust!!! PERFECTION.
You had me at coconut cookie crust! Key lime pie just got even tastier in my book. Scrap the graham crackers! A coconut cookie crust is where it’s at!!!
Well, I don’t care how healthy or unhealthy these are, they look AWESOME!! ;)
You mention mixing butter into the crust, yet I don’t see it as an ingredient. How much?
Gah! So sorry about that. Thanks for letting me know! I’ve fixed it. :)
Love that you made key lime pie into easy-to-make bars!
Happy Birthday!
These sound awesome! I may have to try them out. I used to not like key lime anything and then I got older and I love key lime. I use the key lime juice that I can buy in a bottle at the grocery store. I am invited to a pool party later in the summer and this will be perfect to take to that party! Can’t wait!
Oh and peanut butter pie is my favorite pie for sure!
It’s hard to beat peanut butter pie for sure!
Thanks so much, Kelly! It’s great that you’ve grown to like key lime treats. I keep waiting for me to grow to like vegetables but it hasn’t happened yet. ;) I hope you’ll enjoy these and that they’ll be a big hit at the pool party!
This looks amazing. I do take offense with the comment in your email that you “assume that no one who eats grain free would be interested in this recipe”. I am very interested in this recipe, and I do not eat grains because of an autoimmune disease, no other reason. This does not mean that I do not enjoy rich, sugar laden sweets occasionally. I hope this statement is not indicative of your inner landscape as a human being, it isn’t very nice, more judemental.
I’m sorry you found it offensive and judgemental! I certainly didn’t mean it to be. I actually thought I was quite careful with how I worded it by using the word ‘assume’ and ‘likely.’ I wrote, “I was assuming that someone who eats grain-free likely wouldn’t be interested in this filling recipe.” I guess I should have written “a lot of people who eat” and not “someone who eats.” I made this remark based off of all the comments and emails I’ve gotten about how this or that grain-free recipe looks great but because it calls for white sugar, the commenter would never make it (as written, anyway) because, as I’ve been told again and again, if one avoids grains, then one usually avoids white sugar, as well. Of course I don’t assume that the comments of some apply to all grain-free eaters (which is why I said ‘likely’). Sorry again that you found it to be judgemental!
