Description

A Minty Treat That Would Make Grandma Proud

Growing up in an Italian-American household, our cookies were usually buttery biscotti or soft amaretti. But my love for Thin Mints came much later—thanks to a neighbor who introduced me to them during a winter cookie swap. When I transitioned to a low-carb lifestyle, Thin Mints were one of the hardest treats to give up. So I did what any devoted cookie-lover would do: I recreated them, keto-style.


Ingredients

Scale

For the Chocolate Cookie Base:

  • 1 cup almond flour

  • 1/4 cup cocoa powder (unsweetened)

  • 1/4 cup powdered erythritol

  • 1/4 tsp salt

  • 1/4 tsp baking soda

  • 1/2 tsp peppermint extract

  • 1/2 tsp vanilla extract

  • 1/4 cup butter, softened

  • 1 tbsp almond milk (or as needed)

For the Chocolate Mint Coating:

  • 3/4 cup sugar-free dark chocolate chips

  • 1 tbsp coconut oil

  • 1/2 tsp peppermint extract


Instructions

🥣 Step 1: Prepare the Dough

  1. In a medium bowl, whisk together almond flour, cocoa powder, erythritol, salt, and baking soda.

  2. Add softened butter, peppermint extract, and vanilla extract.

  3. Mix until crumbly. Add almond milk a little at a time until a dough forms.

  4. Roll the dough into a log, wrap in plastic, and chill in the fridge for at least 30 minutes.

Tip: Chilling helps the cookies keep their shape while baking.


🍪 Step 2: Slice & Bake

  1. Preheat oven to 350°F (175°C).

  2. Line a baking sheet with parchment paper.

  3. Slice the dough log into 1/4-inch rounds and place them on the baking sheet.

  4. Bake for 10–12 minutes until just set. Let cool completely before handling.


🍫 Step 3: Coat in Chocolate

  1. Melt chocolate chips and coconut oil in a microwave-safe bowl in 30-second intervals.

  2. Stir in peppermint extract.

  3. Dip each cooled cookie into the chocolate coating using a fork.

  4. Let the excess drip off and place the cookies on parchment paper.

  5. Chill until the coating is firm.
