  • 1 cup all-purpose flour
  • 1 cup cornstarch
  • 1 teaspoon baking powder
  • ¼ teaspoon baking soda
  • ¼ teaspoon kosher salt
  • ½ cup granulated sugar
  • 8 tablespoons unsalted butter 1 stick, at room temperature
  • 2 large egg yolks
  • 2 teaspoon finely grated lemon zest divided.
  • 1 teaspoons vanilla extract
  • 2 tablespoons warm water
  • 1 cup coconut flakes
  • 8 ounces Dulce De Leche homemade or store bought


  • In a large bowl, sift together the flour, cornstarch, baking powder, baking soda and kosher salt. Set aside
  • In the bowl of an electric mixer, beat sugar and butter until light and fluffy, about 3 minutes. 
  • Add yolks and beat to combine.  
  • Add the vanilla extract, water and lemon zest beat until just combined. 
  • Add flour mixture, and mix on low speed until the dough just comes together.
  • Wrap the dough in plastic and chill until firm, at least 2 hours.
  • Heat oven 350 degrees. Line baking sheets with parchment paper. 
  • Remove dough from plastic wrap and place on a lightly floured surface, flour a rolling pin and roll out to about ¼ inch thick. Cut the dough with a 2 inch cookie cutter.
  • Place cookies on prepared sheet pans about about 1 inch apart.
  • Bake for about 9 minutes or until firm and edges are pale golden and the middle of the cookie is firm.
  • Transfer baking pan to a rack and allow to cool completely before removing from baking sheet. 
  • Spread 1 tablespoon of dulce de leche onto the back of half the cookies. Place a second cookie on top and gently press to create a sandwich and repeat.
  • Roll sides in coconut and dust generously with powdered sugar before serving.

  • Freeze cookie dough for up to 3 months. Wrap in plastic wrap and and place inside a freezer plastic bag. Label the bag with the month and the baking temperature and place the bag in the freezer.
