Ingredients

  • 1/2 vanilla bean
  • 3/4 cup plus 2 tablespoons cold unsalted butter, cubed
  • 1 cup plus 1 1/2 tablespoons powdered sugar
  • 4 large egg yolks
  • 1/2 orange, zested
  • Pinch baking powder
  • Pinch salt
  • 2 cups all-purpose flour
  • 3/4 cup plus 2 tablespoons cold unsalted butter, cubed
  • 1/2 vanilla bean
  • 1 cup plus 1 1/2 tablespoons powdered sugar
  • 4 large egg yolks
  • 1/2 orange, zested
  • Pinch baking powder
  • Pinch salt
  • 1 2/3 cup all-purpose flour
  • 1/2 cup unsweetened Dutch-processed cocoa powder

Method

  • For the Plain Dough: Using a sharp knife, slice the vanilla bean in half lengthwise.
  • Separate the seeds from the outside skin by scraping the blade of the knife along the inside of the bean.
  • Place the vanilla bean seeds, butter, sugar, egg yolks, and orange zest in a medium-sized mixing bowl and beat with an electric mixer on low speed until the ingredients are combined, about 1 minute.
  • Combine the baking powder, salt, and flour and add to the butter mixture all at once.
  • Beat on low speed just until combined, about 1 minute.
  • Do not overmix the dough or it will become tough.
  • Remove the dough from the bowl.
  • Form it into a 4 by-9-inch rectangle, wrap in plastic, and place in the refrigerator.
  • For the Chocolate Dough: Repeat the exact same procedure as for the plain dough, combining the cocoa powder with the flour and adding it to the butter mixture.
  • Let each dough rest in the refrigerator for at least 1 hour.
  • (I prefer to make the dough a day in advance and let it rest overnight.)
  • Overnight, all of the flavors (orange, vanilla, chocolate, butter) mature and the flour and butter absorb the flavor of the cocoa.
  • The next day, the chocolate dough will be darker in color.
  • Preheat the oven to 400 degrees F. Remove the dough from the refrigerator.
  • It will be hard, so give it a few quick raps with a rolling pin to make it easier to roll.
  • Lightly flour both sides of each dough.
  • Roll both doughs into a 7 by 6-inch rectangle about 1/8-inch thick.
  • Place one rectangle on top of the other and roll it out to an 8 by 20-inch rectangle.
  • Brush the rectangle with a thin coat of water to help the dough stick to itself.
  • Roll the dough into a cylinder that is 20 inches long and 1 1/2 to 1 3/4-inches in diameter.
  • Cut the cylinder into 1/2-inch thick round slices.
  • Lay the cookies, cut side down, on a parchment paper-covered baking sheet about 1/2-inch apart.
  • Bake until lightly browned, about 15 minutes and cool on a wire rack.
  • Store the cookies in an airtight container at room temperature for up to 5 days.
