Dulce de Leche Sandwich Cookies (Alfajores)

These Dulce de Leche Sandwich Cookies or Alfajores are soft, tender cookies filled with deliciously sweet dulce de leche. They are easily one of my favourite sandwich cookies!

Who wouldn’t like 2 delicious cookies sandwiching a delicious, caramel-like filling? If this person exists, I have yet to meet them. These cookies are always a hit wherever I bring them and it’s not hard to see why! The perfect ratio of cookie to filling is so satisfying delicious!

Dulce de leche is a caramel like treat made from sweetened milk that is cooked until the sugar caramelizes. You can find it at some grocery stores but it is very easy to make at home. I make it in my slow cooker and it is honestly the simplest thing to do!

How to make Homemade Dulce de Leche

To make dulce de leche at home, all you need is a can of sweetened condensed milk. I remove the label from the can and place it in my slow cooker. Then I fill the slow cooker with water so that the can is completely submerged. Set the slow cooker on low for 8 hours and walk away. Thats it. Before opening the can, allow it to come to room temperature first.

Ingredients in Dulce de Leche Sandwich Cookies

  • Softened butter
  • Sugar
  • Egg
  • Salt
  • Vanilla extract
  • Flour (all purpose)
  • Dulce de leche

How to Make the Dulce de Leche Sandwich Cookies

To make the cookies, I use my basic sugar cookie recipe. It is simple but flavourful and works deliciously well with dulce de leche. The full recipe is in the recipe card but essentially, it comes down to these easy steps:

  • Cream together butter and sugar.

  • Add the egg, vanilla, salt.

  • Add the flour.

  • Form the dough into 4 disks and chill it.

  • Roll out the dough and cut with cookie cutters.

  • Bake!

  • Cool and stuff with dulce de leche!

Tips for making the best dulce de leche cookies:

While this recipe is pretty easy, there are a few things to keep in mind to ensure the best results.

  • Chill your dough. Since the base of this cookie is a sugar cookie recipe, it is important to chill your dough so it is easier to work with (and not sticky).

  • Make sure cookies are the same thickness. I like to use thick wooden skewers or thick chopsticks on either side of my rolling pin to ensure that the cookies come out a uniform size (thickness).

  • Don’t make your cookies too thick. Again, the wooden skewers help with this. You want a good ratio of dulce de leche filling to cookie.

  • Cool the cookies before filling them. The filling will melt and begin to ooze if the cookies are still warm so allow them to cool before you make the sandwiches.

I hope you enjoy these cookies!

Ingredients
  

  • 1 cup butter softened
  • 1 cup sugar
  • 1 large egg
  • 1/2 teaspoon salt
  • 1 1/2 teaspoons vanilla extract
  • 3 cups flour
  • dulce de leche (for homemade recipe, see blog post above)

Instructions
 

  • Preheat oven to 350F and line 2 baking trays with parchment paper.
  • In the bowl if a stand mixer, cream the butter and sugar until fluffy using the paddle attachment. Add the egg, salt and vanilla extract and mix until well blended. With the mixer on low, add the flour and mix until it is thoroughly blended.
  • Transfer the dough to your work surface and divide it into 4 equal portions. Form each one into a a disk shape and cover with food wrap. Place in the fridge to cool for 5 minutes.
  • Roll each disk to desired thickness. I use 2 wooden skewers as a guide and roll the dough between the skewers with a rolling pin to ensure they are all the same height.
  • Use your cookie cutter to cut out your cookies and carefully transfer to baking sheets. Bake in the oven for approximately 12 minutes or until the middle of the cookies no longer looks ‘wet’ and the bottom is beginning to brown slightly.
  • Cool cookies on a cooling rack. Once cooled, spoon a tablespoon of dulce de leche on one cookie and place another on top, pressing down gently.
