What Are Cornstarch Alfajores?

Cornstarch alfajores are traditional Latin American cookies made by sandwiching a generous amount of dulce de leche between two soft, crumbly cookies. The key difference between these and the traditional alfajores is the use of cornstarch instead of wheat flour, resulting in a lighter, more delicate texture.

These cookies are popular in countries like Argentina and Peru, where they are enjoyed during festive occasions and as a sweet treat with coffee or tea.

Historical Background of Cornstarch Alfajores

The origins of alfajores can be traced back to Spain, where they were introduced during the Moorish occupation. The recipe evolved over time, incorporating local ingredients and flavors as the treat spread across Latin America. In countries like Argentina and Peru, alfajores became a staple in local cuisine, each region adding its unique twist to the classic recipe.

The use of cornstarch in alfajores likely emerged as a way to create a lighter, more delicate cookie, distinguishing them from the denser, flour-based versions.

The Role of Cornstarch in Alfajores

Cornstarch plays a crucial role in achieving the signature texture of these cookies. Unlike wheat flour, cornstarch doesn’t develop gluten, which means the dough remains tender and crumbly. This results in a cookie that practically melts in your mouth, providing a delightful eating experience.

Additionally, cornstarch helps to stabilize the dough, making it easier to handle and roll out without becoming sticky.

How to Make Cornstarch Alfajores: A Step-by-Step Recipe

Ingredients:

• 1 ½ cups cornstarch

• 1 cup all-purpose flour

• 1 cup unsalted butter, softened

• 1 cup powdered sugar

• 2 egg yolks

• 1 tsp vanilla extract

• ½ cup dulce de leche

• Powdered sugar or grated coconut for dusting

Instructions:

1. Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper.

2. Mix the dry ingredients: In a large bowl, whisk together the cornstarch and flour.

3. Cream the butter and sugar: In another bowl, beat the softened butter and powdered sugar until light and fluffy.

4. Combine the mixtures: Gradually add the dry ingredients to the butter mixture, mixing until a smooth dough forms. If the dough is too dry, add a tablespoon of milk.

5. Roll out the dough: Turn the dough onto a floured surface and roll it out to about ¼ inch thickness. Use a cookie cutter to cut out circles.

6. Bake: Place the dough circles onto the prepared baking sheets and bake for 10–12 minutes, or until the edges are lightly golden.

7. Cool: Allow the cookies to cool completely on a wire rack.

8. Assemble: Spread a generous amount of dulce de leche on the bottom of one cookie and top with another to form a sandwich.

9. Dust: Lightly dust the assembled cookies with powdered sugar or roll the edges in grated coconut.
