Delicious homemade Thin Mint Cookies featuring a rich chocolate and peppermint flavored dough dipped in smooth semi-sweet chocolate. These classic cookies are perfect for holiday treats or anytime you crave a refreshing chocolate-mint dessert.


Ingredients

Scale

Cookie Dough

  • 3/4 cup unsalted butter, softened to room temperature
  • 1 cup granulated sugar
  • 1 large egg, at room temperature
  • 1 teaspoon pure vanilla extract
  • 1/4 teaspoon peppermint extract
  • 1 and 1/2 cups all-purpose flour (spooned & leveled)
  • 3/4 cup unsweetened natural cocoa powder (or dutch process)
  • 1 teaspoon baking powder
  • 1/8 teaspoon salt

Topping

  • 14 ounces quality semi-sweet chocolate, coarsely chopped
  • 1/2 teaspoon canola or vegetable oil
  • 1/4 teaspoon peppermint extract


Instructions

  1. Prepare Butter and Sugar: In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the softened butter for 1 minute on medium speed until smooth and creamy. Add granulated sugar and beat on medium-high speed until the mixture is fluffy and light in color.
  2. Add Wet Ingredients: Beat in the egg, vanilla extract, and peppermint extract on high speed until fully combined. Scrape down the sides and bottom of the bowl as needed.
  3. Combine Dry Ingredients: Sift the flour and cocoa powder together in a medium bowl. Whisk in baking powder and salt until evenly mixed.
  4. Mix Dry Into Wet: On low speed, slowly add the dry ingredients to the wet ingredients and mix until combined, forming the cookie dough.
  5. Chill the Dough: Divide the dough into two equal portions. Roll each onto parchment paper to about 1/4-inch thickness. Stack the rolled dough with parchment between layers on a baking sheet and refrigerate for at least 1 hour. Cover with parchment if chilling more than a couple of hours. Can chill up to 2 days.
  6. Preheat Oven and Prepare Baking Sheets: Once chilled, preheat the oven to 350°F (177°C). Line 2-3 large baking sheets with parchment paper or silicone mats.
  7. Cut Cookies: Remove one dough piece from the fridge and cut into 2-inch circles using a cookie cutter. Transfer cut cookies to the prepared baking sheets. Re-roll scraps and continue cutting until all dough is used.
  8. Bake Cookies: Bake for 10 minutes or until edges appear set. Rotate baking sheets halfway through. Cookies will be soft in centers.
  9. Cool Cookies: Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before dipping.
  10. Melt Chocolate Topping: Melt chopped chocolate and oil together in a double boiler or microwave in 15-second increments, stirring after each until smooth. Stir in peppermint extract.
  11. Dip and Set Cookies: Dip each cooled cookie fully into the melted chocolate using a fork, allow excess chocolate to drip off tapping on bowl edge. Place dipped cookies on parchment or silicone mat-lined baking sheet and refrigerate until chocolate sets.
  12. Store Cookies: Store leftover cookies covered at room temperature for 2-3 days or refrigerate for up to 1 week. Cookies also taste great frozen.

Notes

  • Cookies freeze well for up to 3 months; thaw overnight in refrigerator before serving.
  • Dough can be chilled for up to 2 days before baking.
  • Cookie dough can be frozen before rolling for up to 3 months; thaw overnight and bring to room temperature before rolling.
  • Avoid mint extract; peppermint extract pairs best with chocolate for authentic flavor.
  • For a slice-and-bake option, shape dough into 2-3 inch logs, chill for 1 hour, then slice into 16-18 cookies before baking.
  • Use electric mixer with paddle attachment, rolling pin, cookie cutters, baking sheets, parchment paper, silicone mats, cooling rack, and double boiler or microwave-safe bowl for best results.
