Ingredients

  • 3/4 cup unsalted butter
  • 1 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon pure peppermint extract (not mint extract)
  • 3/4 cup Dutch (dark) cocoa powder, you can use regular also but, the Dutch is best
  • 1 teaspoon baking powder
  • 1/4 teaspoon sea or kosher salt
  • 1 1/2 cups all purpose flour

Chocolate Glaze

  • 2 cups  semi sweet chocolate chips
  • 1/2 cup heavy cream
  • 1/4 teaspoon pure peppermint extract, not mint extract

Instructions

  1. Homemade Thin Mint Cookies: Using a standing mixer or hand held mixer, cream the butter and sugar until light and fluffy. Beat in the egg, vanilla and peppermint extract until combined and smooth. In a medium mixing bowl, whisk together the flour, cocoa powder, baking powder and salt. Gradually mix in the dry ingredients into the wet until a soft dough forms. Using two silicone baking mats, roll the dough out into 1⁄2” thick. Place cookie dough in fridge for about 1 hour. Preheat oven to 350 degrees and line two cookie sheets with parchment paper or silicone baking mats. Using a 2 inch round cookie cutter, cut out 24 round cookies. Place the cookie rounds onto the cookie sheets and bake for9-12 minutes or until the are firm around the edges but soft in the center. Let cool on pan for about 3 to 4 minutes, then slide off onto a wire rack. Allow to cool completely.

    Chocolate Glaze: Have a medium mixing bowl ready with the chocolate chips. In a small saucepan or pot, bring the heavy cream to a very low simmer. Pour the hot heavy cream over the chocolate chips. Let sit for 1 minute before whisking until smooth. Whisk in the peppermint extract. Using a fork, dip 1 cookie at a time and lightly tap the side oft he bowl to remove excess chocolate back into the bowl. Place the freshly dipped cookie onto a cookie sheet lined with a silicone baking mat or parchment paper. Continue to dip the remaining cookies. Once all cookies have been dipped, scoop the rest of the chocolate into the disposable piping bag. Cut the tip off the piping bag and drizzle over the chocolate coated cookies. Allow the chocolate to fully harden. Then, dig in and enjoy!

Recipe Notes

Storage

  • Store at room temperature for up to 4 days in an airtight container. 
  • Refrigerate for up to a week in an airtight container. 
  • Wrap cookies in plastic wrap and freeze them for up to 3 months in an airtight, freezer-safe container or heavy-duty freezer bag. 

Tips

  • Mix the cookie dough just until it comes together. Don't overwork it.
  • It's important to chill the dough before baking to control its spread.
  • It's important to let the chocolate chips sit in the hot cream before whisking. It ensures the chocolate easily blends with the cream and creates the best texture.
  • Lightly tap the fork against the bowl when dipping the cookies to remove excess chocolate.
