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 & Coating

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


Instructions

  1. Dry ingredients: Sift together the all-purpose flour, cornstarch, baking powder, and salt into a small bowl to ensure even distribution and remove any lumps.
  2. Wet ingredients: In a large mixing bowl, cream the softened butter and granulated sugar until the mixture is light and fluffy. Add egg yolks one at a time, mixing thoroughly after each addition, then stir in the pure vanilla extract to infuse flavor.
  3. Combine: Gradually add the dry ingredients to the butter mixture, mixing with a spatula or your hands to form a smooth, cohesive dough without overworking it.
  4. Chill: Divide the dough into two equal portions, wrap each in plastic wrap, and refrigerate for at least one hour to firm up for easier handling and better texture.
  5. Oven preparation: Preheat your oven to 350°F (175°C, Gas Mark 4). Line two baking sheets with parchment paper to prevent sticking and ensure even baking.
  6. Cut: Roll out each dough portion to about ¼ inch thickness between sheets of parchment paper to prevent sticking. Use a heart-shaped cookie cutter to cut out shapes and arrange cookies spaced evenly on the prepared baking sheets.
  7. Bake: Place the baking sheets on the middle rack of the oven and bake for 8 to 10 minutes, or until the cookies are just turning golden at the edges while remaining pale and tender inside. Avoid overbaking for the best texture.
  8. Cool: Let the cookies cool on the baking sheets briefly before transferring them to a wire rack to cool completely, ensuring they set properly before filling.
  9. Sandwich: Spread a generous layer of dulce de leche onto the flat side of one cooled cookie, then top with another cookie to form a sandwich.
  10. Coat: Roll the edges of the dulce de leche-filled sandwiches in desiccated coconut evenly to add texture and flavor.
  11. Store: Place the finished alfajores on a tray or plate and let them set for at least one hour to allow the flavors to meld and the coconut coating to adhere firmly before serving.

Notes

  • Use room temperature butter for easier creaming and better dough texture.
  • Chilling the dough is essential for easier rolling and maintaining cookie shape.
  • If dulce de leche is too thick, warm slightly to make spreading easier.
  • These cookies are best enjoyed within 2-3 days but can be stored in an airtight container refrigerated for up to a week.
  • To make homemade dulce de leche, simmer sweetened condensed milk gently until caramelized.
