Chocolate Mint Wafers
If you adore the combination of chocolate and mint, this may become your favorite cookie. |
- 8 tablespoons (1 stick) unsalted butter, room temperature
- 1/2 cup granulated sugar
- 1 large egg, room temperature
- 1 cup unsweetened cocoa powder
- 1/2 cup plus 2 tablespoons all-purpose flour
- Confectioners sugar, for rolling out dough
- 1/2 cup heavy cream
- 12 ounces semisweet chocolate, finely chopped
- 4 to 6 drops peppermint oil, or 1 teaspoon pure peppermint extract
|
1. In the bowl of an electric mixer fitted with the paddle attachment, cream butter and sugar on medium speed until completely smooth, about 3 minutes. Add egg, and continue mixing until well combined. |
2. In a medium bowl, whisk together cocoa powder and flour. |
3. Add flour mixture to butter mixture; mix on low speed until combined, scraping down sides of bowl once. Divide dough in half; wrap each half in plastic. Flatten each half into a disk; chill until firm, at least 1 hour. |
4. Preheat oven to 350°. Line two baking sheets with Silpat baking mats or parchment paper. Set prepared pans aside. |
5. Lightly sprinkle a clean work surface with confectioners sugar. Roll out dough to an 1/8-inch thickness. Using a 2-inch cookie cutter, cut out cookies, and transfer to prepared baking sheets, spacing cookies 1/2 inch apart. Chill any trimmings, and roll out again. |
6. Bake the cookies until you can smell chocolate, about 12 minutes. Transfer the baking sheets to a wire rack to cool. |
7. Bring cream to a boil in a small saucepan set over medium-high heat. Add chocolate to hot cream. Stir with a rubber spatula until chocolate has melted and mixture is smooth. Add peppermint oil. Remove from heat; let ganache cool slightly, about 20 minutes. |
8. Transfer chocolate to a resealable plastic bag; seal, and cut off one corner at an angle. Pipe about 1 teaspoon onto the center of half of the wafers. Top with the remaining wafers. Chill the assembled cookies until firm, about 10 minutes. Store in an airtight container up to 2 days. |
