There’s something timeless about the cool, chocolatey crunch of a thin mint cookie. For many, it brings back memories of childhood, Girl Scout cookie season, or cozy evenings with a hot drink and a little sweet indulgence.

Ingredients You’ll Need
To keep this recipe authentically keto and as close to the traditional flavor as possible, here’s what you’ll need:
For the Cookies:
-
1 cup almond flour (super-fine blanched)
-
1/4 cup unsweetened cocoa powder
-
1/4 cup powdered erythritol (or any keto sweetener of choice)
-
1/4 tsp baking soda
-
1/8 tsp sea salt
-
1/4 cup unsalted butter (softened)
-
1 tsp peppermint extract
-
1/2 tsp vanilla extract
For the Chocolate Coating:
-
3/4 cup sugar-free chocolate chips (such as Lily’s)
-
1 tbsp coconut oil
-
1/2 tsp peppermint extract
Equipment
-
Mixing bowls
-
Electric hand mixer or stand mixer
-
Rolling pin
-
Parchment paper
-
Baking sheet
-
Cooling rack
-
Small saucepan or microwave-safe bowl
Step-by-Step Instructions
Step 1: Prepare the Cookie Dough
In a medium bowl, combine the almond flour, cocoa powder, erythritol, baking soda, and salt. Stir well to eliminate any lumps. In another bowl, cream the softened butter with the peppermint and vanilla extracts using a hand mixer until smooth. Gradually add the dry ingredients to the wet mixture and blend until a thick, slightly sticky dough forms.
Step 2: Chill the Dough
Transfer the dough onto a piece of parchment paper. Shape it into a disk, wrap it, and refrigerate for at least 30 minutes. Chilling the dough helps firm it up and makes it easier to roll and cut into uniform shapes.
Step 3: Roll and Cut the Cookies
Preheat the oven to 325°F (165°C). Once the dough is chilled, roll it out between two sheets of parchment paper until it’s about 1/8 inch thick. Use a small round cookie cutter or shot glass to cut out circles. Place them on a parchment-lined baking sheet about 1 inch apart.
Step 4: Bake
Bake the cookies for 12 to 14 minutes, depending on thickness. They should be firm on the edges and slightly soft in the center—they will harden as they cool. Let them rest on the baking sheet for 5 minutes, then transfer to a cooling rack.
Step 5: Make the Chocolate Coating
In a small saucepan over low heat (or using the microwave in 30-second increments), melt the sugar-free chocolate chips with the coconut oil. Once smooth, stir in the peppermint extract. Make sure the mixture is not too hot before dipping.
Step 6: Dip and Set
Dip each cooled cookie into the chocolate mixture, letting the excess drip off. Place the dipped cookies back on the parchment-lined baking sheet. Refrigerate for 20 minutes or until the coating is set.

Tips for Perfect Keto Thin Mint Cookies
-
Use finely ground almond flour for the best texture.
-
Chill the dough thoroughly to ensure your cookies hold their shape.
-
Roll the dough evenly for consistent baking.
-
Do not overbake. They may seem soft out of the oven but will crisp up as they cool.
-
Use high-quality peppermint extract to achieve the classic minty flavor.
Variations and Substitutions
-
Nut-Free Option: Substitute almond flour with sunflower seed flour for a similar texture.
-
Extra Crunch: Add a tablespoon of crushed sugar-free peppermint candy to the cookie dough.
-
Double Chocolate: Mix a tablespoon of sugar-free chocolate chips into the dough before baking.
-
Coconut-Free Coating: Use butter instead of coconut oil in the chocolate coating if you’re sensitive to coconut.
Perfect Pairings
Enjoy these cookies alongside a warm cup of keto hot chocolate, peppermint tea, or a cold almond milk latte. For a dessert board, pair them with other keto treats like peanut butter fat bombs or no-bake chocolate truffles.
Keto Lifestyle Benefits
