Classic alfajores filled with dulce de leche and rolled in shredded coconut. They are so soft they’ll melt in your mouth!
Prep Time 15 minutes
Cook Time 15 minutes
Chill time 2 hours
Total Time 2 hours 30 minutes
YIELD 3 dozen 2-inch cookie sandwiches

Ingredients

  • 1 ½ cups (200g) all-purpose flour
  • 2 ⅛ cups (300g) cornstarch
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • 1 and ¾ sticks (200g) unsalted butter, at room temperature
  • ¾ cup (150g) granulated sugar or 1 ¼ cups (150g) powdered sugar
  • 3 large egg yolks
  • 2 teaspoons vanilla extract
  • 350 g (12 oz.) dulce de leche, for filling
  • ½ cup unsweetened shredded or desiccated coconut , for rolling

Instructions

  1. In a medium bowl, sift together flour, cornstarch, baking powder, and baking soda. Set aside.
  2. In a mixer bowl fitted with the paddle attachment, beat butter and sugar on medium speed until light and fluffy, about 3 minutes. Beat in egg yolks and vanilla extract just until combined. Reduce speed to low. Add the flour mixture and beat just until combined. Do not overmix or the cookies will turn out tough.

  3. Form the dough into a ball, then flatten slightly to form a disc. Wrap with plastic wrap and refrigerate for 1-2 hours, until firm enough to roll.
  4. If you don’t want to use the dough right away, you can refrigerate it for up to 3 days or freeze it for up to a month, then thaw it overnight in the fridge.
  5. Take the dough out of the fridge and let it sit on the counter for a few minutes to soften slightly for easy rolling. On a lightly floured surface (or between 2 pieces of parchment paper), roll the dough to a ⅛ or ¼-inch (3-5mm) thickness. Cut out into rounds using a 2-inch (5cm) fluted or round cookie cutter, and place the cookies on baking sheets lined with parchment paper.
  6. If at any point the dough becomes too warm, place it back into the fridge for a few minutes. Re-roll the remaining scraps and repeat. Place sheets with cookies in the freezer or fridge for at least 15 minutes, until firm, so that they will be less prone to spreading.
  7. Preheat oven to 350F/180C. Bake for 7-10 minutes, or until cookies appear golden brown at the edges. Allow cookies to cool in the pan for 10 minutes, then gently transfer to a wire rack to cool completely.
  8. Spread the bottom half of the cookies with dulce de leche (about a teaspoon). Sandwich together with remaining cookies, pressing slightly so that the caramel oozes out the sides. Roll the sides in shredded coconut.
  9. Store cookies at room temperature in an airtight container for up to a week or freeze for up to 2 months. To thaw, leave on the counter, still covered, or overnight in the fridge.

Recipe Notes

Tips for making the best alfajores cookies:

  • When making the dough, if it feels dry, you can add a little bit of cold water or milk a little at a time, just until the dough comes together.
  • Mix the dough just until the ingredients are combined. If mixing for a long time, the cookies can turn out tough from producing too much gluten. Overall, play with the dough as little as possible.
  • While it can be tempting, don't fill your alfajores with too much dulce de leche because the cookies may start to fall apart with too much filling.
