These richly-filled, crisp cookies are bliss to bite into.


  • Cookies:
  • 1/2 cup unbleached all-purpose flour
  • 1/2 cup cake flour
  • 3/4 cup cornstarch
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 3/4 cup (1-1/2 sticks) butter at room temperature
  • 3/4 cup cofectioners' sugar
  • 1 teaspoon pure vanilla extract
  • Buttercream Filling:
  • 1/4 cup (1/2 stick) unsalted butter, softened at room temperature
  • 3/4 cup confectioners' sugar
  • 1 teaspoon pure vanilla extract
  • 1/2 ounce dark bittersweet chocolate, melted


  1. Position a rack in the middle of the oven. Heat oven to 300 degrees F. Line two baking sheets with parchment paper.
  2. Into a medium-sized bowl, sift both flours, cornstarch, baking powder and salt and set aside.
  3. In a large bowl and using an electric mixer on medium speed, beat the butter, sugar and vanilla until smooth and lightened slightly in color, 1 minute. Stop the mixer and scrape the sides of the bowl as needed during the mixing.
  4. Mix in the flour mixture just until the flour is incorporated and a smooth dough forms.
  5. For each cookie, roll a level tablespoon of dough between the palms of your hands into a smooth ball. Place the cookies on the prepared baking sheets, spacing them 2 inches apart.
  6. Use a fork to gently flatten the cookies to 1-1/4-inch disks and to make an impression of the fork tines in the top of each.
  7. Bake the cookies one sheet at a time until the tops feel firm but do not darken, about 30 minutes or just set.
  8. Transfer the cookies to a wire rack to cool completely.
  9. In a second medium-sized bowl, mix butter, sugar and vanilla until smooth. Stir in melted chocolate.
  10. Turn half of the cooled cookies bottom side up. Use a thin metal spatula to spread a rounded teaspoon of filling evenly over bottom of each.
  11. Gently press the flat bottom of the remaining cookies on the filling. Serve at room temperature.
