Buttery Argentinian Alfajores Filled With Dulce de Leche

Alfajores are the butter cookies sandwiched with dulce de leche, the ones you eat in two bites. I use a thick layer of the caramel so it stays inside instead of squishing out.

The recipe is straightforward, making it accessible for bakers of all skill levels. Enjoy these alfajores with a cup of coffee or tea for a delightful afternoon snack.

Traditional Alfajores Recipe with Dulce de Leche

These alfajores are made from a tender dough flavored with a hint of vanilla and cornstarch, giving them a melt-in-your-mouth texture. The cookies are filled with creamy dulce de leche and then rolled in powdered sugar, making them a decadent treat that serves about 12 people.

Ingredients

1 cup unsalted butter, softened
1/2 cup granulated sugar
2 large egg yolks
1 teaspoon vanilla extract
1 1/2 cups all-purpose flour
1/2 cup cornstarch
1 teaspoon baking powder
1 cup dulce de leche
Powdered sugar for dusting

Instructions

Cream the Butter and Sugar: In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the egg yolks and vanilla extract, mixing until combined.
Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cornstarch, and baking powder. Gradually add this mixture to the wet ingredients, mixing until a soft dough forms.
Chill the Dough: Wrap the dough in plastic wrap and refrigerate for about 30 minutes to firm it up, making it easier to handle.

Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
Shape the Cookies: Roll small balls of dough into flat discs about 1/4 inch thick. Place them on the prepared baking sheet, leaving space between each cookie for spreading.
Bake: Bake for 10-12 minutes, or until the edges are lightly golden. Allow cookies to cool completely on a wire rack.

Assemble: Spread a generous amount of dulce de leche on the flat side of one cookie and top it with another cookie to form a sandwich.
Dust with Powdered Sugar: Before serving, dust the assembled alfajores with powdered sugar for an elegant finish.
