These keto mint chocolate bars are a delicious sugar free dessert recipe. They’re easy to make, with a no bake chocolate crust, a creamy, minty green filling, and a rich chocolate glaze.
This recipe goes out to all of my chocolate mint lovers. I know you’re out there!
Seriously, these keto no bake dessert bars are pure chocolate and mint heaven. They’re a delicious twist on my famous Keto Nanaimo Bars, and it’s an excellent twist indeed.
I have to say that these delicious bars exceeded my expectations. Mind you, I expected them to be good as it was. But when I bit into one, I found myself weak in the knees. They were so tender, so creamy, and so deliciously minty.
I foresee these bars being very popular. Possibly as popular as my Keto Thin Mints and my Keto Peppermint Patties. And that’s saying something!
Classic Nanaimo Bars are one of my favorite desserts so I don’t enter into this flavor variation lightly.
I often saw other flavors of the famous Canadian dessert growing up, but I always eschewed them in favor of the original. The other flavors were never as good and often far too sweet and cloying, and I felt that they sullied the reputation of the real thing.
But as I often do, I was poking about on Pinterest and saw these No Bake Mint Chocolate Bars from The Recipe Rebel. And my first thought was that crust looked exactly like a Nanaimo Bar crust.
They looked so tempting, I thought I’d give them a keto makeover. And while I can’t wrap my head around calling them Nanaimo Bars, I can say that they’re pretty freaking awesome.
How to make Keto Mint Chocolate Bars
Don’t be at all intimidated by the long ingredient list and instructions. These keto dessert bars are easy to make, with ingredients you probably already have in your pantry! Here are my best tips for getting it right.
- Prepare the crust. This crust isn’t baked, but you do cook the ingredients together in a pan over low heat. It takes an egg, and by cooking it with the butter and cocoa powder, you both thicken the mixture and cook the egg enough to be safe.
- Press the crust into the pan. Press it in firmly and evenly. The mixture will seem a bit greasy as you do this but it will absorb as it cools. You do not need to grease the pan because the mixture has plenty of oil.
- Chill the crust. It needs at least 20 minutes to firm up properly.
- Prepare the filling. This filling doesn’t take custard, like a classic Nanaimo Bar. Instead it’s more of a buttercream frosting with mint.
- Add a touch of green. Or not! I love the look a bit of natural green food coloring gives these bars but you can leave it white if you prefer.
- Chill them again. They go back into the fridge to firm up the filling.
- Prepare the chocolate glaze. This is a simply glaze of chopped sugar free chocolate and butter melted together. As always, do it double boiler style so you don’t seize the chocolate.
- Chill them once more to firm up the chocolate.
Decorating the top of the bars
Curious about the pretty chevron design on the top of my bars? Okay, let’s discuss.
It’s an extra step for these keto chocolate mint bars, so it’s absolutely optional. Keep in mind that it adds nothing to the flavor, it’s simply for appearances. But it is fun so if you’re interested, here’s what I did:
- Melt some white chocolate with a bit of cocoa butter. I actually had some mint white chocolate from ChocZero but it’s seasonal and not available at the moment. Simply use regular white chocolate and it will give you the same effect.
- Drizzle lines over the chocolate glaze. Do straight lines across the pan in only one direction.
- Drag the lines. Drag a toothpick or skewer across the lines and it will create little chevrons. Do it in one direction down the pan and back in the other direction. Make the drag lines about 1 inch apart.
- Work quickly! Both the chocolate glaze and the white chocolate lines need to be quite soft as you do this so you need to be quick.
- Note that on some of my bars, you can see the lines the toothpick made in the chocolate glaze. I wasn’t quite fast enough because I trying to get photos of the process so I could show you! If you can do it quickly, the glaze is still soft enough that it fills in as you drag the toothpick across.
Frequently Asked Questions
Coconut flour won’t work in the crust but you can use sunflower seed flour instead. See how to make your own sunflower seed flour. It’s easy!
Use another ⅔ cup almond flour to give the crust of these chocolate mint bars the right structure.
The crust should be fine with any sweetener but I do recommend powdered or liquid to avoid grittiness. The filling really needs a bulk powdered sweetener for a proper buttercream consistency. Some of them are two times as sweet as sugar so be careful to read your labels.
Do keep in mind that if you experience the cooling sensation with erythritol based sweeteners, then this is the perfect recipe. You’re supposed to get a cooling minty sensation with mint bars!
I haven’t tried, but I imagine you could. You can easily replace the butter with coconut oil and the cream cheese with dairy free cream cheese.
For the chocolate glaze, coconut oil will make it very hard when chilled and it will crack when you cut it. I suggest using a tablespoon of coconut cream instead, to make a softer topping.

No Bake Keto Chocolate Mint Bars
- ½ cup butter
- ⅓ cup cocoa powder
- 6 tablespoon powdered Swerve Sweetener
- 1 large egg lightly beaten
- 1 teaspoon vanilla extract
- 1 cup almond flour
- ⅔ cup shredded coconut
- ⅓ cup chopped pecans (optional)
- 4 ounces cream cheese softened
- ½ cup butter softened
- 1 cup powdered Swerve Sweetener
- 2 tablespoon heavy whipping cream room temperature
- 2 teaspoon peppermint extract
- Natural green food coloring
- 3 ounces sugar free dark chocolate chopped
- 2 tablespoon butter
- ½ ounce sugar-free white chocolate chips (optional)
- ¼ ounce cocoa butter
- In a medium saucepan over very low heat, melt the butter. Stir in the cocoa powder and sweetener, and then slowly whisk in the egg.
- Cook, stirring constantly, until mixture thickens. Remove from heat and stir in the vanilla, almond flour, shredded coconut and nuts. Press crust into a 9×9 or 8×8 square pan evenly and refrigerate until firm, about 20 minutes.
- In a large bowl, beat the cream cheese and butter together until smooth, then beat in the sweetener until well combined.
- Add the whipping cream and peppermint extract and beat until smooth. Beat in just enough food coloring to achieve a minty green.
- Spread the filling over the crust and refrigerate until firm, about 30 minutes.
- In a heatproof bowl set over a pan of barely simmering water, stir the chopped chocolate and butter together until melted and smooth. Spread over the chilled bars.
- Refrigerate the bars 20 minutes to set the chocolate OR decorate with white chocolate chevrons as described below.
- If you want to make the white chocolate chevron decorations, you will need to work quickly. I recommend melting the white chocolate at the same time as you are making the chocolate glaze.
- In a heatproof bowl set over a pan of barely simmering water, melt the white chocolate chips with the cocoa butter, stirring until smooth.
- Immediately after spreading the chocolate glaze on the bars, drizzle the white chocolate overtop in straight lines across.
- Then immediately drag a toothpick from one side of the bars to the other, across the white chocolate lines. Do this in opposite directions to create chevrons.
- Refrigerate the bars 20 minutes to set the chocolate.
You have GOT to make these! Sooooo good! Thank you for yet another great recipe!!
Could you use fresh mint in these rather than the extract? I have a load of mint in the garden I need to use up
I am not sure how you would add it, but you’re certainly welcome to try!
Is there something you can substitute for the coconut in the crust? I really want to make these, but dislike coconut immensely. Thank you for any help.
Just leave it out.
Thank you for such a DELICIOUS recipe! I made it last night, and it is just so yummy! I made a different base from another Keto cheesecake recipe as I don’t really like coconut, and that has worked well!
Have I missed the finer details on what size to cut the bars/one serve in grams to correlate to the Nutrition Facts percentages?
No… I don’t measure it by grams. Simply cut into 16 even bars.
I made these with my cousin a couple days ago, I loved the filling and the topping, but I could do without the crust. I didn’t enjoy the coconut in the crust. So I am eating the tops and off and tossing out the crust. They came out absolutely perfect though.

I just made these last night. They taste amazing!
The only trouble I had was cutting and then getting them out
Of the pan. Once the chocolate hardened, the top cracked so easily
I did get them out of the fridge at least an hour before I tried cutting
Them into 16, but then they softened too much to get them out so I put them
Back in the fridge. Later when I went to lift out the squares, the chocolate
Shattered again. I’d like to know your secret.
BTW I loved making them green for St. Patrick’s day 🙂
My family loved this! Would like to try this crust as a blonde crust with almond extract and a pineapple or pina colada cream cheese filling. Does it need something to replace the cocoa powder, as it seems to add some bulk to the crust mixture? Thanks for a wonderful dessert.
Yes, you’d need more almond flour.
Stop whatever you are doing and make these NOW! These are BEYOND amazing! I am the sole diabetic in my home and I am very picky about what I put in my body, especially when it comes to ‘sweet treats’ that I technically know I don’t really ‘need.’ My family, friends, and coworkers could not get enough of them! Thank you so much for all your wonderful recipes! They have truly brought joy back into a newly diagnosed diabetic’s life!
Wonderful to hear!
These are amazing! Even my husband loves them. You can’t even tell the difference from the unhealthy version, except you won’t feel guilty eating these!!!! So good!!!
Can these be frozen?
Pam B says
I do not have Peppermint Extract , I have Peppermint oil. So I was wondering if the extract also served as a moisture in the filling or is it just for flavor ?
Just flavor, you should be good.
These are really good! My kids couldn’t stop eating these treats!
Amazing! Oh my goodness, these bars were incredible! My new favorite treat!
Matt J Taylor says
I love mint and chocolate! These Keto mint chocolate bars are awesome, can’t believe they are Keto, they taste so good.
Linda Waller says
This recipe looks great and I’d like to make it for some friends. Unfortunately one lady is allergic to coconut. Any substitutions for the coconut?
Please read the blog post as I already addressed that.
If I don’t want to use shredded coconut in the crust, do I need to add more flour, and how much? Thank you!
Please read the blog post as I already answered that.
I made the recipe and it is really quite good. However, the filling became more crumbly that creamy after it set. Do you have any suggestions? I followed the recipe exactly. Thanks.
What sweetener did you use? Ours stayed nice and creamy.
When an ingredient is listed as optional, do you have to figure the nutritional value in to what is already listed or is it already in the total?
If I used it in my recipe, it’s in the nutritional info.
HUM M M … Quel bonne gâterie saine .
MERCI pour toutes vos recettes simples et délicieuses .
What size of pan did you use for this recipe? I like the one you show in the picture, but I can’t understand if it’s 8 X 8 or 9 X 9 inches… And also have some problems with conversion in metric, since when I search for this kind of pans on webstores the results takes me somewhere to 18 X 18 cm. and somewhere else 20 X 20 or 24 cm. :-/ And lastly, since I can’t buy a piece for each one, what would be more useful in your opinion for the most of the recipes? Better metallic or glass? (Maybe a metallic one… but since I’m asking, I ask for all the details to the expert 😉 )
Sorry, Carolyn! I’ve read after posting my question that below the recipe you put the alternative 8 x 8 OR 9 x 9 for the pan! Was too impatient to catch the right one, it was under my nose, I am so mindless…sorry again!
Looking forward for a video showing us the entire process to make this beauty mouthwatering recipe and take confidence with it!
FYI, because this is no-bake, the exact measurements don’t matter much, if it’s within an inch or a few cm. Because you aren’t baking it, you don’t need to worry about bake time. One will just be a bit wider and shorter, whereas the other will be narrower and taller.
