Girl Scout Thin Mint Cookies
- 1 cup unsalted butter at room temperature
- 1 cup unsweetened Dutch Process cocoa powder
- 1 cup powdered sugar
- 1 teaspoon vanilla
- 1/2 teaspoon salt
- 1 1/2 cups all purpose flour
- chocolate coating:
- 20 ounces semi-sweet baking chocolate or dark dipping chocolate
- 2 teaspoons peppermint extract or oil
Set oven to 350 degrees
Cream butter until light and fluffy, then add the powdered sugar and mix until combined. Stir in the salt, vanilla and cocoa powder. Mix until the cocoa powder is integrated and the batter resembles a thick frosting. Add the flour and mix just until the flour is combined, making sure to not over mix.
Form dough into a ball.
Using about 1/3 of the dough at a time, roll it thin on a lightly floured surface, about 1/8-inch. Cut cookies using 2-inch cutter. Gather the scraps and press together lightly and cut remaining cookies. Place up to 20 cookies on a jelly roll pan, lined with parchment paper or lightly grease a cookie sheet. The cookies will not spread much while baking.
Bake for 10 minutes. Remove the cookies from the oven and allow them to cool completely before removing from baking sheet.
While the cookies bake, make the peppermint coating. Chop the baking chocolate into very small, thin pieces. Place in a glass bowl or similar container and microwave for about 30 seconds at a time, stirring with a spoon or a whisk. When the chocolate is melted, stir in the peppermint extract.
Gently drop the cookies, one at a time, into the coating. Turn to coat entirely, then lift the cookie out of the chocolate with the fork and tap the fork on the side of the pan until the extra coating drips off. Place on a parchment baking sheet, and repeat for the rest of the cookies. Place the cookies in the refrigerator or freezer to set for a few minutes.
Yield about 50-2 inch cookies.
-Fluff the flour and lightly scoop with a spoon into the measuring cup, then level off with a knife to insure you don't get too much flour in the cookie dough.
-The dough is a little stiff and tends to crack while rolling out. If it does, no problem, just press it back together with hands. You can also add a little milk to moisten the dough if needed!
-Melt the chocolate just before you are ready to dip, and make sure to whisk in the extract well.
