I\u2019m so excited to share this Argentinian alfajores dulce de leche sandwich cookies recipe with you! I\u2019ve been dying to make a traditional Argentinian recipe ever since I got back from Buenos Aires. I finally got around to it when my friend from Buenos Aires recently visited and brought me so many goodies from his home. He brought me the best dulce de leche and so many other treats. But I knew I had to use the dulce de leche to make something that I\u2019d had when I was in Argentina. I decided to make these alfajores, which are dulce de leche sandwich cookies, because I love baking. Further, I wanted a challenge. I love making cut-out cookies, but I\u2019ve honestly never really mastered them. They always spread and it drives me crazy! But this recipe was different. The cookies turned out perfectly. The interesting thing about alfajores is that they use corn starch in the dough, along with flour and sugar. I didn\u2019t research it, but I think the corn starch must help with keeping the dough from spreading because they didn\u2019t spread hardly at all. I got these super cute cookie cutters so I could make perfect rounds with little scalloped edges. Even if you think cut-out cookies are hard, I promise this recipe is a breeze. It probably took me 10 minutes to make the dough. After letting it rest in the fridge for an hour, it was a breeze to roll and cut out. I did use quite a bit of flour on my counter and rolling pin so the dough didn\u2019t stick to the rolling pin, but it didn\u2019t seem to affect the taste of the cookies at all. I only had to bake the cookies for 8-9 minutes. Ovens vary so much, just make sure they are the lightest golden brown.\u00a0 Once they are cooled, then the fun starts. I added about 1\/2 tsp of dulce de leche to each cookie, topped it with a matching cookie and dusted them in powdered sugar. I opted not to put the traditional coconut around the edge because my family isn\u2019t that into coconut. I\u2019m so happy with how they turned out! The cookies are buttery and almost melt in your mouth. I actually wish I had added a bit more dulce de leche to give it a super strong taste, but I still loved them. I\u2019m most excited about how well the dough turned out and that the cookies didn\u2019t spread. I\u2019m definitely planning to use that dough as a base for other sandwich cookies in the future. If you have some free time and love baking as much as I do, I highly suggest you try out this recipe. You can find dulce de leche at most grocery stores. If you have trouble with the consistency being too thin, you could try these tips out. Or you could also make your own dulce de leche \u2013 I think this recipe sound pretty great. It was a lot of fun making my first traditional Argentinian recipe. Next up, I need to find a recipe to use the membrillo my friend brought me. Stay tuned! If you'd like to make your own dulce de leche sandwich cookies, this is the recipe i used. Alfajores - Dulce De Leche Sandwich Cookies Ingredients (adapted from Chowhound): 1 cup cornstarch 3\/4 cup all-purpose flour, plus more as needed 1 teaspoon baking powder 1\/2 teaspoon baking soda 1\/4 teaspoon fine salt 8 tablespoons unsalted butter (1 stick), at room temperature 1\/3 cup granulated sugar 2 large egg yolks 1 tablespoon pisco or brandy (optional, I didn't use and they were still great!) 1 tablespoon vanilla extract 1\/2 cup dulce de leche, at room temperature Powdered sugar, for dusting Directions: Place the cornstarch, measured flour, baking powder, baking soda, and salt in a medium bowl and whisk briefly to combine; set aside. Place the butter and sugar in the bowl of a stand mixer fitted with a paddle attachment. Mix on medium speed, stopping the mixer to scrape down the sides of the bowl once with a rubber spatula, until the mixture is light in color and fluffy, about 3 minutes. Add the egg yolks, pisco or brandy, and vanilla and mix until incorporated, about 30 seconds. Stop the mixer and scrape down the sides of the bowl. On low speed, gradually add the reserved flour mixture and mix until just incorporated with no visible white pockets, about 30 seconds. Turn the dough out onto a piece of plastic wrap, shape it into a smooth disk, and wrap it tightly. Place in the refrigerator until firm, at least 1 hour. Meanwhile, heat the oven to 350\u00b0F and arrange a rack in the middle. Line 2 baking sheets with parchment paper and set aside. Remove the dough from the refrigerator, unwrap it, and place it on a lightly floured work surface. Lightly flour the top of the dough. Roll to 1\/4-inch thickness (the dough will crack but can be easily patched back together). Stamp out 24 rounds using a plain or fluted 2-inch round cutter, rerolling the dough as necessary until all of it is gone. Place the cookies on the prepared baking sheets, 12 per sheet and at least 1\/2 inch apart. Bake 1 sheet at a time until the cookies are firm and pale golden on the bottom, about 12 to 14 minutes. (The cookies will remain pale on top.) Transfer to a wire rack to cool completely. Flip half of the cookies upside down and gently spread about 2 teaspoons of the dulce de leche on each. Place a second cookie on top and gently press to create a sandwich. Dust generously with powdered sugar before serving. Enjoy these dulce de leche sandwich cookies!
