Key Ingredients

Every ingredient in these Keto Thin Mint Cookies serves a purpose — from creating the perfect texture to adding that signature minty bite.

Almond Flour
Forms the base of the cookie. It keeps the cookies crisp and low-carb.

Cocoa Powder
Adds rich chocolate flavor and pairs perfectly with the mint.

Erythritol or Monk Fruit Sweetener
A keto-friendly sweetener that gives just the right amount of sweetness without spiking blood sugar.

Butter or Coconut Oil
Adds richness and helps the dough hold together.

Egg
Binds the ingredients and gives structure.

Peppermint Extract
The star flavoring that creates that cool, refreshing taste.

Dark Sugar-Free Chocolate Chips
Used for coating — smooth, rich, and melt-in-your-mouth good.

Step-by-Step

Making these Keto Thin Mint Cookies is simple and fun. Here’s exactly how to do it:

  1. Preheat oven. Set to 350°F (175°C) and line a baking sheet with parchment paper.
  2. Mix dry ingredients. In a bowl, whisk almond flour, cocoa powder, sweetener, baking powder, and a pinch of salt.
  3. Add wet ingredients. Stir in melted butter, egg, vanilla, and peppermint extract. Mix until a dough forms.
  4. Shape the cookies. Roll dough into small balls, flatten gently into rounds (about ¼-inch thick), and place on baking sheet.
  5. Bake. Bake for 10–12 minutes, until firm and crisp around the edges. Let cool completely.
  6. Prepare chocolate coating. Melt sugar-free chocolate chips with a bit of coconut oil until smooth. Stir in peppermint extract.
  7. Dip cookies. Dip each cooled cookie in the melted chocolate, coating both sides. Let excess drip off.
  8. Chill. Place on parchment paper and refrigerate until chocolate hardens.

You Must

To make perfect Keto Thin Mint Cookies, keep these essential steps in mind:

  • Use fine almond flour. It gives the cookies a smooth texture.
  • Let them cool completely before dipping. Warm cookies will break or crumble.
  • Don’t skip chilling. The coating sets best when the cookies are cold.
  • Taste your peppermint extract. Brands vary in strength — add gradually.
  • Store them in the fridge. They taste best chilled and crisp.

Pro Tips

  1. Make them dairy-free. Use coconut oil instead of butter and dairy-free chocolate.
  2. Add espresso powder. A pinch enhances the chocolate flavor beautifully.
  3. Freeze for longer shelf life. Store in an airtight container in the freezer for up to 2 months.
  4. Make minis. Bite-sized cookies are perfect for portion control or parties.
  5. Double the batch. They disappear fast — trust me.

Conclusion

These Keto Thin Mint Cookies deliver all the chocolatey, minty goodness of the original — without the sugar or carbs. Crisp, refreshing, and rich with dark chocolate flavor, they’re the perfect guilt-free indulgence.

Whether you’re following keto or just want a healthier cookie option, these Thin Mints hit every craving. Keep a stash in your fridge or freezer for when you want a little something sweet and satisfying. With one bite, you’ll forget these are even keto — they’re that good.
