Keto Coconut Lime Bars Recipe
Imagine a dessert that tastes like a tropical escape, bright with citrus and rich with coconut, yet fits perfectly into your low-carb lifestyle.
These sugar-free coconut lime bars are exactly that – a little square of sunshine that won’t derail your healthy eating goals. Forget those overly sweet, guilt-inducing treats; it’s time for something both delicious and mindful.
Finding truly satisfying low-carb desserts can be a challenge. Often, they sacrifice flavor or texture in the quest for fewer carbs and no sugar. But what if you could have a vibrant, zesty bar with a delightful crust and a creamy, tangy filling?
This recipe delivers on all fronts, proving that you don’t need sugar to create something truly special. It’s about smart ingredient swaps and balancing flavors to achieve that perfect sweet-tart harmony.
Keto Key Lime Bars
Every great bar starts with a solid base. For these coconut lime bars, we’re using a blend of coconut flour and either sesame or almond flour to create a tender, flavorful shortbread crust that complements the filling without being overly dense.
Combine the dry ingredients – the flours, your chosen sweetener, and a touch of sea salt. Then, cut in the coconut oil until the mixture is crumbly.
This creates that perfect shortbread-like texture. Press this firmly into your prepared baking dish; parchment paper is your friend here for easy removal later. A quick bake in a preheated oven sets the stage for the luscious filling.
While the crust bakes, whip up the star of the show: the vibrant lime filling. This is where the tropical magic truly happens.
You’ll whisk together eggs, fresh lime juice, and plenty of lime zest for that essential bright flavor. Add your sweetener of choice and a hint of coconut stevia to enhance that tropical note.
Once the crust is ready, pour this smooth, zesty mixture over the warm base. A sprinkle of unsweetened coconut flakes on top adds another layer of texture and flavor.
Sugar Free Keto Lime Bars
You can change this fantastic tropical dessert into keto lemon bars by simply swapping the fresh limes and using lemon juice and zest instead.
Simple Ingredients
sesame flour or almond
Swerve confectioners sweetener
coconut oil room temperature or melted butter
Large eggs
Key Lime juice or lemon juice
Lime zest or lemon zest
Unsweetened shredded coconut flakes
Low Carb Sweetener Options
If you don’t have coconut stevia or prefer to use another low carb sweetener, no problem. Use my Sweetener Guide and Conversion Chart to help you decide how much of another sweetener to use to replace stevia.
I prefer to not use any sugar alcohols as I find they tend to crystalize in the fridge.
These days I’m enjoying using a combination sweetener that combines Monk Fruit and Allulose and I find it perfect in the amount of sweetness for keto baked desserts.
How to Store Keto Coconut Lime Bars
Allowing the bars to cool properly is crucial for them to set completely. Once cooled, lift them out using the parchment paper and slice into squares. These bars are best kept refrigerated, perfect for a cool, refreshing treat any time.
Once cooled, and sliced into servings you can place each in a cupcake liner or use parchment paper and layer into an airtight container to place in the fridge. Best stored in the fridge for up to 5 days. You can also freeze for up to one month.
Making recipes like this one might bring you a little piece of the tropics in your mind. In just one bite of these sweet and tart bars you will be transported to tropical place.
It’s a little like a shortbread cookie crust on the bottom with a soft top layer.
A match made in heaven.
That’s all we want on a low carb diet isn’t it?

These were amazing!
I have been craving key lime pie.. these are a slice of heaven with my morning coffee and keto lifestyle.
I know this post is a few years old. I just had a question about the nutritional information. The serving size says 1 gram per serving, is that correct? Which means a 3oz or 4oz bar would be around 141g = 1400 calories?
My recipe plug in had a glitch and converted all my recipes serving size to 1 gram, just a pain to try to manually fix all of them.The recipe makes 16 bars. So the serving size is 1 bar.
Hi! I made these and love the flavor and texture, but had a hard time getting the swerve to mix and blend. The sugar kept settling in the bottom of the bowl. Should I have used the regular granulated swerve?
No I would think the granulated would not work as well as the confectioners.I used confectioners. I’m sorry you had trouble with it.
In your recipe you do not state POWDERED SWERVE good thing I took the time to read the reviews! Sooo just to be clear is it granulated Or powdered? Thank you
It’s confectioners, thanks for letting me know I had forgotten to update it in the ingredients, all set now.
Late to the party but tried this yesterday and was most pleased! Thanks for an excellent recipe! I had to sub almond flour for the sesame as another commenter suggested and completely forgot to add stevia which I didn’t have anyway. Turns out that for me, the erithrithol was just the right amount of sweetness, no stevia necessary. Nice to find this recipe especially as I cook for my diabetic mom who has quite a sweet tooth! Will be trying more of your recipes, thanks and cheers!
Great to hear thank you!
The crust is way too soft- almost like eating straight coconut flour. Definitely needs more coconut oil or butter to hold it together like a shortbread cookie. The flavor is fantastic though!
Did you change out some ingredients. Mine held together fine as you can see from my pictures.
Just made this…man this is goooooo yummy! Highly addictive! Love love love the crust! I had to bake mine for about 20m to get it to set and could have gone probably about 2-3 more minutes more….may be where I live..higher elevation? Awesome recipe! Thanks! Now I’ve got to figure other recipes with that crust…it is sooo good!?
Can I use powdered Swerve or xylitol? If so, would the amount be the same?
Where does the salt go in crust or custard … Seems that info is missing in recipe directions
Thanks so much
I will add that to the directions, thanks for pointing it out. It goes into the crust.
Just made these and HAD to comment. I didn’t have limes so subbed lemon. Also used coconut sugar in place of swerve. I had to double the coc oil because I’m guessing the coconut sugar is more course than swerve? Anyhow, these just got out of oven 40 min ago and fantastic! Thanks for a great recipe
I have just made these, & they are amazing…thank you for posting them.
On a side note, I Live on the stunning West Coast Of Scotland, & I can’t see any other buildings, or hear any traffic noise…it’s absolute bliss. All that I see are pheasants, deer, & lot’s of other wildlife.
I often think, I’ll make up some of your recipes, then I get comfortable outside ( when the sun shines )
& just relax..”.I’ll make that recipe tomorrow ” seems to be my mantra, as I’m sooo comfortable in my little world .We grow our own organic veg, & are hoping, like yourself , to get chickens this year,
I hope all your dreams came true, & others who read your logs…God bless from Marion,
Your land sounds like paradise, simple and beautiful! I’m happy you enjoyed the recipe as well and God bless you!
I made these for guests the other night. I made them in the morning before work and took them out to let them soften a bit while we were having dinner. They were absolutely fantastic, our guests loved them and had no idea they were sugar free!!
Awesome!
Does the coconut oil need to be solid, but soft? RT here at this time of year yields melted coconut oil in my house 🙂
Yes that will be fine soft or melted.
Mmmm, lime & coconut! Fingers crossed you find the land & house of your dreams!
Hmm, I don’t see the Swerve edit yet.
IN step 3 you had just 1/4 cup swerve to the crust ingredients. Then in step 7 you add the remaining 1 cup swerve to the egg mixture.
Hi……could you just use some coconut extract in place of the coconut stevia? The stevia is so pricey so I was looking for an alternative. Thanks for your help.
Yes I’m sure that would be fine.
I am making these tonight! Brenda, can you tell me why the Swerve is listed as divided?
Thank you fora catching that, I edited the recipe in the directions, my mistake but all set now.
Good luck with your search! And there is definitely something to be said for staying close to family. I live away from mine and I miss them daily. Coconut and lime is such a wonderful combination, and these bars look irresistibly good!
Oh how I hate moving. As a military family, we do A LOT of it. We’re basically down to the most necessary items so it’s not too painful anymore 🙂 Those bars look so moist and tasty! I wish I could grab one of your board 😉
That definitely sounds like a wonderful goal – best of luck finding a good house on some good land! I’m a sucker for pretty much any sort of citrus bar…these would be no different, they sound tangy and delicious.
Good luck with the move – and I hope your new home is your match made in heaven (just like these yummy bars!)
thank you so much!
I love the combination of lime and coconut
It’s good that you put your home wishes down on paper (so to speak) because it will guarantee you’ll get what you want. Or at least that’s my belief. Best of luck house hunting and with the move when the time comes. Until then this recipe looks totally delicious. I love the combination of lime and coconut and I especially love that these are sugar free and low carb. I’m pinning them with the hopes to make them ASAP,
These look lovely, I’m thinking of whipping up a batch this weekend……quick and easy, I love that….thank you!
Is Pyure organic stevia a good choice for baking? I don’t prefer the ‘cool’ aftertaste of Swerve.
I’ve used Pyure and found it to be good but much sweeter than Swerve so I would say use just 1/2 cup.
These sound amazing! I need a little bit of tropical sweetness in my life. I don’t have swerve though. What can I use in its place??
Thank you Rejane! You would need another sugar free substitute to replace it. I’m not sure using stevia alone will provide that height or volume in the top layer but it could still work.
