You can use small snowflake, Christmas tree, or other holiday cutters to make the cutout windows. Bake the cutouts at 325 degrees until the edges are firm, 6 to 8 minutes. Ingredients ¾ cup unbleached all-purpose flour, plus more for dusting ⅓ cup unsweetened Dutch-process cocoa powder ⅛ teaspoon kosher salt 6 tablespoons unsalted butter, room temperature ¾ cup confectioners' sugar 1 large egg, room temperature ½ teaspoon pure vanilla extract 4 ounces milk chocolate, finely chopped (¾ cup) ½ cup heavy cream ½ teaspoon pure peppermint extract ¼ cup peppermint candies, finely chopped (3 tablespoons) Directions Whisk together flour, cocoa, and salt. In a large bowl, beat butter with confectioners' sugar on medium-high speed until pale and fluffy. Beat in egg and vanilla. Gradually add flour mixture, beating to combine. Divide dough into 2 disks; wrap each in plastic and refrigerate until firm, about 1 hour. Preheat oven to 325 degrees. Working with one disk at a time (keeping the other refrigerated), roll out on lightly floured parchment to a scant 1/8 inch. Cut out 60 rounds total with a 1 3/4-inch fluted round cutter. Chill and reroll scraps (if dough becomes too soft, freeze 15 minutes). Use a 1/2-inch fluted round cutter to cut out centers of half of rounds. Arrange rounds 1 inch apart on parchment-lined baking sheets. Freeze until firm, 15 minutes. Brush off excess flour with a dry pastry brush. Bake, rotating sheets once, until edges are firm, 13 to 15 minutes. Transfer cookies on sheetsto a wire rack; let cool completely. Place chocolate in a heatproofbowl.
