The Best Alfajores Recipe

Creating the perfect alfajores requires attention to detail and quality ingredients. The balance of flavors and textures in these cookies makes them truly exceptional. Let’s dive into what makes these alfajores the best.

Notes on Ingredients

  • Flour: Sifted all-purpose flour ensures a light, delicate cookie.
  • Confectioners’ Sugar: Provides sweetness and a smooth texture.
  • Cornstarch: Adds tenderness to the cookies.
  • Butter: Use unsalted butter for the best flavor.
  • Vanilla Extract: Adds a fragrant, warm note.
  • Dulce de Leche: The rich, caramel filling that makes alfajores irresistible.
  • White Sugar: Adds a touch of sweetness to the dough.
  • Salt: Enhances the flavors of the other ingredients.

How to Make Alfajores

  1. Prepare the Dough: In a bowl, mix flour, 1/2 cup confectioners’ sugar, cornstarch, and salt. In a separate bowl, beat butter until soft and fluffy. Add white sugar and vanilla, mixing until well combined. Gradually incorporate the dry ingredients into the wet mixture in three batches, blending until just combined.
  2. Chill the Dough: Divide the dough into two portions, shape each into a log, and refrigerate until firm, about 2 hours.
  3. Bake the Cookies: Preheat your oven to 350°F (175°C). Slice the chilled dough into 48 cookies, each about 1/4 inch thick. Arrange them on ungreased baking sheets and bake for 8-10 minutes, until edges are lightly golden. Allow cookies to cool on the baking sheet for a minute before transferring to wire racks to cool completely.
  4. Assemble the Sandwiches: Generously spread dulce de leche on half of the cooled cookies, then top with the remaining cookies to create sandwiches.
  5. Finish with a Dusting: Lightly dust the completed alfajores with the remaining confectioners’ sugar.

How to Serve Alfajores

Alfajores are best enjoyed with a hot cup of tea or coffee. Their delicate texture and rich filling make them a perfect treat for afternoon tea or as a sweet ending to any meal. Arrange them on a decorative plate for an appealing presentation.

How to Store Alfajores

To keep your alfajores fresh, store them in an airtight container at room temperature for up to a week. For longer storage, you can refrigerate them for up to two weeks. Bring them to room temperature before serving for the best flavor and texture.
