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.

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 ¼ 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

Can I make these keto thin mints nut-free?

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.

How about dairy-free?

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.

Can I use a different sweetener?

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.

What about rolling the dough into logs and slicing it?

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.

My chocolate coating seized, what did I do wrong?

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.

Can I make these keto thin mints in advance?

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.

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 ¼ 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.

Notes

*Cook’s Notes: some chocolate melts more thickly than others. Cocoa butter is the best way to thin out the coating. Butter and coconut oil are okay but some chocolate seems to end up more thick when using dairy.
