Ingredients

Scale

Dry Ingredients

  • 2 cups (250 g) All-purpose flour
  • ½ cup (65 g) Cornstarch
  • ½ tsp Baking powder
  • ½ tsp Salt

Wet Ingredients

  • 1 cup (227 g) Unsalted butter, softened
  • ½ cup (100 g) Granulated sugar
  • 3 large Egg yolks
  • 1 tsp Pure vanilla extract

Filling and Coating

  • 1 ½ cups (339 g) Dulce de leche (store-bought or homemade)
  • ½ cup (40 g) Desiccated coconut

Instructions

  1. Mix Dry Ingredients: Sift together the all-purpose flour, cornstarch, baking powder, and salt into a small bowl to ensure they are evenly combined and free of lumps.
  2. Prepare Wet Ingredients: In a large mixing bowl, cream the softened unsalted butter and granulated sugar until the mixture is light and fluffy. Add the egg yolks one at a time, mixing well after each addition, then stir in the vanilla extract to incorporate fully.
  3. Combine Dough: Gradually add the dry ingredients into the wet mixture, stirring or kneading gently with a spatula or your hands until a smooth dough forms, avoiding overworking.
  4. Chill Dough: Divide the dough into two equal parts and wrap each portion in plastic wrap. Refrigerate for at least one hour to firm up for easier handling.
  5. Preheat Oven: Set your oven to 350°F (175°C) or Gas Mark 4. Line two baking sheets with parchment paper to prevent sticking and for easy cleanup.
  6. Roll and Cut: Roll each dough portion between two sheets of parchment paper to approximately 1/4-inch thickness. Use heart-shaped cookie cutters to cut out the cookies and place them spaced apart on the prepared baking sheets.
  7. Bake Cookies: Bake on the middle rack of the preheated oven for 8 to 10 minutes, until the edges are lightly golden but the centers remain tender and pale to ensure softness.
  8. Cool Cookies: Remove the baking sheets from the oven and allow the cookies to cool on the sheets for a few minutes before transferring them to wire racks to cool completely.
  9. Assemble Sandwiches: Once cooled, spread a generous amount of dulce de leche on the flat side of one cookie and top with another cookie to form a sandwich.
  10. Coat Edges: Roll the edges of each dulce de leche-filled heart-shaped cookie in desiccated coconut, ensuring the coating adheres evenly around the sides.
  11. Set and Serve: Place the coconut-coated alfajores on a tray or plate and let them set for at least one hour to let the flavors meld and the coconut adhere firmly. Serve and enjoy!

Notes

  • Ensure the butter is softened but not melted for proper creaming with sugar.
  • Do not overbake the cookies; they should remain tender and pale for the ideal texture.
  • Use a chilled dough as it’s easier to roll and cut into shapes without sticking.
  • If dulce de leche is too thick, warm it slightly to spread more easily.
  • Store alfajores in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
