Keto Thin Mints are crispy keto cookies with a sugar-free mint chocolate coating. They’re the perfect way to indulge in Girl Scout cookies without all the sugar and carbs.
Fact: Nothing derails a keto diet faster than a box of Girl Scout Cookies. But never fear, Keto Thin Mints are here!
These are the low carb cookie recipe of your dreams. Or maybe my dreams. Perhaps we’ve been dreaming about this together. This thin mint cookie recipe was first posted in 2011.
Those Girl Scouts will be knocking on your door soon, and I so thought it was time I gave these beloved sugar free cookies a little update. Because you need all the help you can get to ward off the sugary temptation.
Sugar-free Girl Scout cookies
If you have trouble resisting the sweet and tasty treats sold by Girl Scouts, you are not alone.
The only possible solution? Making your own healthier versions at home. Whatever your favorite flavor is, I have a keto-friendly version. Such as keto tagalong bars, keto Samoa bars, and even keto Do-si-do cookies.
And of course, these delicious Keto Thin Mints.
All of these recipes really satisfy that craving for cookies. And best of all, they’re easy enough to make any time you need them.
Ingredients
This Keto Thin Mints recipe uses standard low carb ingredients that are readily available at most grocery stores. You will need:
- Almond flour
- Cocoa powder
- Erythritol sweetener (such as Swerve)
- Baking powder
- Salt
- Egg
- Butter
- Vanilla extract
- Peppermint extract
- Cocoa butter (or coconut oil)
- Sugar-free dark chocolate
How to make keto thin mints
It’s easy to make these crispy keto chocolate cookies. Be sure to check out the video in the recipe card for step-by-step instructions.
The cookies
Thin mints start with a good crisp chocolate wafer. I use these same wafers in my keto oreos too!
- Use finely ground almond flour: As always, a good fine almond flour produces the best results in keto baking. Your cookies will be more cohesive and crisp up better. Read more about baking with almond flour.
- The sweetener matters: I know everyone has their preferences but only erythritol-based sweeteners, such as Swerve, produce crisp cookies.
- Roll the dough evenly: I like to roll mine less than 1/4 inch thick, so that I get a lot of cookies. But what matters most is that they are all of an even thickness, so that they bake evenly.
- Cut out circles: Grab a 2-inch round cookie cutter and get cutting!
- Bake at a low temperature: I keep my oven at 300 degrees Fahrenheit for these keto thin mints, so that they crisp up without burning. How long they take depends on how thinly you rolled out the dough.
The coating
Now for the fun part… dipping the wafers in a minty chocolate coating.
- Don’t use unsweetened chocolate! Several readers have made the mistake of using unsweetened chocolate, which has absolutely no sweetener whatsoever. And of course the keto thin mints turned out quite bitter! Make sure you are using a good no-sugar-added chocolate like Lily’s, which is sweetened with erythritol and stevia.
- Set up a double boiler: A double boiler allows you to melt the chocolate more gently, without overheating it.
- Add a little oil to thin the chocolate coating, making it easier to dip the wafers.
- Mint extract to taste: I recommend using an oil-based extract, to make the chocolate less likely to seize. I use a teaspoon of Frontier peppermint flavor but you can always use more if you prefer a stronger flavor.
- Dip the wafers: Drop them into the melted chocolate, toss them to coat, and lift out with a fork. Then tap the fork on the side of the bowl to remove excess chocolate. Place the keto thin mints on a waxed paper lined baking sheet until set.
Pro tip: Freeze the wafers before you start dipping them, so that the chocolate sets faster. It’s much less messy that way!
Frequently Asked Questions
Sure thing! Try using sunflower seed flour in place of the almond flour. You may need a little bit more to firm up the dough properly.
That works too! Try using coconut oil in place of the butter for the cookies and make sure to use dark chocolate for the coating.
If you want crisp cookies, you must use an erythritol based sweetener such as Swerve or Lakanto. Any amount of allulose will make these cookies very soft and spongey.
You could do that, but if you want nice even circles, I recommend rolling the dough out and cutting with a cookie cutter. The slice-and-bake method would be just as much work, in my opinion.
There are a couple of possibilities. You may have let the heat get too high when melting it. And you may have gotten some liquid in there, as any amount of water will cause seizing.
Yes! They are a great make-ahead cookie. You can either just make the wafers, and dip them when ready, or you can make the finished cookies and freeze those.
Storage Instructions
Store the cookies at room temperature in a covered container for up to a week, or in the fridge for 10 days. They can also be frozen for several months.
Keto Thin Mint Cookies Recipe
Ingredients
Cookies:
- 1 3/4 cups (180 g) almond flour
- 1/3 cup (78.86 g) cocao powder
- 1/3 cup (60.67 g) Swerve Sweetener
- 1 tsp baking powder
- 1/4 tsp (0.25 tsp) salt
- 1 large egg, slightly beaten
- 2 tbsp butter, melted
- 1/2 tsp (0.5 tsp) vanilla extract
Coating:
- 1/2 ounce (1 tbsp) cocoa butter, or 1 tbsp coconut oil**
- 7 oz (198.45 g) Lily’s dark chocolate, chopped
- 1 tsp peppermint extract
Instructions
Cookies
- Preheat the oven to 300F and line two baking sheets with parchment paper.
- In a large bowl, combine almond flour, cocao powder, sweetener, baking powder and salt. Add in egg, butter and vanilla extract and stir well until dough comes together.
- Roll out dough between two pieces of parchment paper to desired thickness, but no more than 1/4 inch thick. Lift off top piece of parchment and set aside.
- Using a 2-inch diameter cookie cutter, cut out circles of dough and lift gently. Place cookies on prepared baking sheet. Gather up scraps of dough and reroll until too little is left to roll out.
- Bake cookies until firm to the touch,20 to 30 minutes (this will vary depending on how thinly you rolled your dough). Remove and let cool. They will continue to crisp up as they cool.
- Pro tip: Once cool, place the wafers in the freezer so the chocolate sets faster.
Chocolate Coating
- Set a heatproof bowl over a pot of gently simmering water. Add the chocolate and cocoa butter, stirring frequently until smooth and melted. Remove from heat and stir in the peppermint extract.
- Dip the cookies into the chocolate, using two forks to turn over and fully coat cookie.
- Lift out the cookie and gently tap the fork on the side of the bowl to remove excess chocolate, then place on a waxed paper lined baking sheet.
- Refrigerate until fully set.

By far my favorite Girl Scout cookie EVER! I could eat the whole batch myself.
One of my all time favorites – love these cookies!
Yes! I need these!
SO PUMPED ABOUT THESE! I LOVE thin mints!
Love having a low-carb option for thin mints!
Would love some guidance! The cookies are really good, and the coating is where it became awful.
The 100% dark chocolate used was the Montezum bar from Trader Joe’s.
It melted beautifully with the butter and then I added the peppermint extract.
Without any sweetener they aren’t tasting anything like a thin mint. Since it doesn’t call for sweetener, could the chocolate be just to bitter/dry tasting?
Would love to be proud of them and so far, not even close.
That’s just it. You’re not supposed to use 100% cacao, unsweetened chocolate. I make it VERY clear in my post that it’s sugar-free chocolate like Lilys. So yep, it would be pretty awful.
Any idea what the nutrition information would look like without the chocolate coating? I am planning to use just the cookie part as a substitution for crumbled Oreos (without the filling) in a recipe. Thanks!!
Not sure but you could enter it into My Fitness Pal.
Can you use oils for the peppermint? Like Doterra brand.
I don’t but I am sure you can. Just go lightly, they tend to be stronger.
These sound amazing!!! I can’t wait to try them. You mention Swerve Sweetener and/or Stevia in your recipe. I don’t see mention of Erythritol. I would love to use erythritol as I enjoy the taste. Is it a 1:1 substitute for what you have listed as the sweeteners in the recipe?
I just read your response about Swerve being a brand of erythritol. I didn’t realize that. So you are referring to plain erythritol when you mention “Swerve sweetener”?
No, when I say Swerve Sweetener, I mean Swerve Sweetener. Because it’s a blend of erythritol and oligosaccharides designed to measure exactly like sugar.
I see a nutritional info disclaimer, but I do not see any nutritional info at all on this page for this recipe-where is it?
It’s all right at the bottom of the recipe.
Made these today! They are amazing I truly felt like
Was eating Girl Scout thin mints. Thank you so
Much!
Yay!
I followed this to the T. Awful. Bitter. Tried sweetening the chocolate coating to no avail. Expensive fail.
Why would you need to sweeten the coating? I suspect you used UNSWEETENED CHOCOLATE and not sugar-free dark chocolate. Which yes…would result in awfully bitter cookies.
I had to add about 1/4 cup of THM super sweet (which is erythritol and stevia) to the dough because it didn’t taste like it would be sweet enough for me after it baked, and I only had a 1 1/2” cookie cutter, and my cookies accidentally got baked at 350 so I took them out after 10 minutes. They crisped up wonderfully! I also added peppermint to the dough! These are so yummy and addictive! Thank you!
Is Stevia glycerite ok to use here?
Hi Carolyn. I prefer allulose to swerve…do you think that would work for the cookies? Obviously, I would need to use a little more…
NOPE! You won’t get anything close to a crisp cookie. Please read this: https://alldayidreamaboutfood.com/best-keto-sweeteners/
Made these today, and they turned out great! I’ve always hated rolling and cutting out any cookie/crust, so I used two mini muffin silicone pans. Used a teaspoon cookie scoop amount in each well and pressed that down and baked them according to recipe time. Then, instead of taking the cookies out of the pan and dipping them, I melted some sugar free chocolate chips, added some coconut oil, and used the teaspoon scoop again to cover just the tops of the cookies with chocolate right in the pan. Cooled them a bit in the fridge and then popped them outta the pan. Pow! So easy and fabulous! Thanks, Carolyn!
I made the thin mints today. They are delicious but I had a problem with the coating. I had to substitute unsweetened chocolate for sugar free..so I added Splenda. It tastes good but the coating looks like it has sand in it. Is that the Splenda?
Yes, that would be the Splenda, it does not combine well with chocolate.
