Description

Delicate and crumbly cornstarch cookies filled with rich dulce de leche and finished with a light coconut coating. These alfajores melt in your mouth and offer a perfect balance of sweetness and citrus aroma.


Ingredients

  • 2 cups cornstarch
  • 1 cup all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 150 grams unsalted butter, softened
  • 3/4 cup powdered sugar
  • 3 egg yolks
  • 1 teaspoon vanilla extract
  • 1 teaspoon lemon zest
  • 1 cup dulce de leche
  • 1/2 cup shredded coconut

Instructions

  1. Preheat oven to 170°C (340°F) and line a baking tray with parchment paper.
  2. Sift together cornstarch, flour, baking powder, and baking soda in a bowl.
  3. In another bowl, beat butter and powdered sugar until light and creamy.
  4. Add egg yolks one at a time, mixing well after each addition. Stir in vanilla extract and lemon zest.
  5. Gradually add dry ingredients to the wet mixture, mixing gently until a soft dough forms.
  6. Roll out the dough on a lightly floured surface to about 1/2 cm thickness.
  7. Cut into rounds using a cookie cutter and place on the prepared tray.
  8. Bake for 10–12 minutes until bottoms are lightly golden while tops remain pale.
  9. Cool completely on a wire rack.
  10. Spread dulce de leche on one cookie, sandwich with another, and gently press.
  11. Roll the edges in shredded coconut to finish.

  • Substitute orange zest for a different citrus flavor.
  • Store in an airtight container for up to 3 days.
