Thin Mint Cookies

Neil sent me a recipe for these cookies, knowing they are among QC’s and my favorite cookies.

Well, they weren’t exactly thin but they were minty. I am not exactly thin either so I don’t hold that against them.

Not the prettiest cooking to photograph, but who cares?

When I make these again, and rest assured I WILL be making these again, I will roll between waxed paper instead of parchment paper. The dough is quite sticky and distorted when trying to remove them from the paper and put on a baking sheet.

I also think coating in tempered chocolate might help as this chocolate will melt in your hands, as well as your mouth.

Thin Mint Cookies

½ cup butter
½ cup granulated sugar
½ cup brown sugar
1 egg
1 cup AP flour
½ teaspoon baking powder
½ teaspoon salt
1/3 cup cocoa powder
½ teaspoon pure peppermint extract
Chocolate Coating:
8 ounces baking chocolate
¼ teaspoon vegetable oil
¼ teaspoon pure peppermint extract


  1. Preheat the oven to 350°F.
  2. In a bowl, combine the flour, baking powder, salt and cocoa powder. Whisk until smooth.
  3. In a mixing bowl, cream the butter and sugars until light and fluffy. Mix in the egg and peppermint extract. Gradually mix in the dry ingredients until the dough comes together. Use your hands to form the dough into a ball.
  4. Place the ball of dough onto a sheet of parchment paper. Flatten it into a disk and put another piece of parchment paper on top. It may be a good idea to use waxed paper as the dough is very sticky and did not remove from the parchment paper easily.
  5. Use a rolling pin to roll out the dough to 1/4-inch thick. Transfer the rolled dough, with the parchment paper, onto a baking sheet.
  6. Place the baking sheet in the freezer to chill for 10 minutes.
  7. Transfer the flattened dough to a countertop. Remove the top sheet of parchment paper and use it to line the baking sheet.
  8. Use a small, circular cookie cutter to cut out disks of dough. Transfer the cut disks onto the prepared baking sheet, leaving space in between. Because the dough is chilled, these cookies won’t spread too much while baking. I collected the excess dough, re-rolled and chilled to make about 8 more cookies.
  9. Place the baking sheet in the oven and bake for 11 minutes. Once baked, remove the cookies from the oven, then transfer the parchment paper and cookies to a cooling rack to fully cool.
  10. Set up a double boiler and chop the chocolate. Add the chopped chocolate into the bowl of the boiler and stir in the vegetable oil. Stir the chocolate until fully melted and stir in the peppermint extract. Next time I will temper the chocolate. These cookies much be refrigerated or the chocolate will melt in your hands.
  11. Use a slotted wooden spoon to make the dipping process easier. Place a cookie on the wooden spoon. Dip it into the chocolate or use a large spoon to help cover the cookie. Tap the spoon gently against the bowl to remove excess chocolate. Once covered in chocolate, transfer each cookie back to the baking sheet lined with parchment paper. Place the baking sheet in the fridge for 20 minutes to allow the chocolate to fully set and harden.

• Thin Mints are best enjoyed cold.
• Store in an airtight container in the freezer or fridge.
• Keep in the freezer for one to two months, or in the fridge for two weeks. This will also keep the chocolate coating at its best.
• Store in an airtight container for two days.
