Alfajores Recipe

Dough Preparation

Now that you have your ingredients and tools ready, let’s focus on creating that soft, delicate dough. The right dough will give the alfajores their signature melt-in-your-mouth texture. Here’s how we go about it:

Mixing the Dry Ingredients

First, grab your all-purpose flour (1 ½ cups/200g) , cornstarch (1 ⅞ cups/300g) , baking powder (2 teaspoons) , and baking soda (½ teaspoon) . In a medium bowl , sift these dry ingredients together. You’ll want to do this carefully to ensure there are no lumps and that the baking powder and baking soda are evenly distributed throughout the flour and cornstarch mixture. Once the dry ingredients are combined, set the bowl aside for later.

Why sift? Sifting helps aerate the ingredients, ensuring the cookies turn out light and tender, which is exactly what we want!

Creaming the Butter and Sugar

Next, take your unsalted butter (1 ¾ sticks/200g) —make sure it’s at room temperature for easy mixing—and place it into the bowl of your mixer. Add the sugar, whether you’ve opted for granulated (¾ cup/150g) or powdered sugar (1 ¼ cups/150g) . Using your mixer fitted with the paddle attachment , beat the butter and sugar on medium speed until the mixture is light and fluffy —this should take about 3 minutes.

Pro Tip: The key to great texture is that perfectly fluffy butter-sugar mixture. You want it to be pale and airy, which ensures the cookies bake up soft and crumbly.

Incorporating the Yolks and Vanilla

Once you’ve reached the fluffy butter and sugar stage, it’s time to add the 3 egg yolks and 2 teaspoons of vanilla extract . Add them one at a time, making sure each yolk is fully incorporated before adding the next. You don’t want to overmix this step; mix just until everything is combined. This will ensure that your cookies remain tender.

Combining the Wet and Dry Ingredients

Now, reduce the mixer speed to low, and gradually add the dry ingredients you sifted earlier to the butter mixture. Slowly mix everything until the dough begins to form. Ensure you don’t overmix , as this can make the cookies tough rather than delicate.

If the dough looks a little dry or crumbly at this stage, here’s a tip: Add a little cold water or milk , just a bit at a time, until the dough comes together smoothly.

Resting the Dough

Now the dough needs to rest, which is crucial for making it easier to handle! Shape the dough into a ball, then flatten it slightly into a disc. Once formed, wrap it in plastic wrap and refrigerate for 1-2 hours so it firms up and is easier to roll out.

Not in a rush? No problem! You can leave the dough in the fridge for up to 3 days or even freeze it for a month . If frozen, thaw it overnight in the fridge when you’re ready to bake.

Shaping and Baking the Cookies

Now that your dough has had time to chill and firm up, it’s time for the fun part: shaping the dough into adorable, round alfajores and baking them to golden perfection!

Baking the Alfajores

Rolling Out the Dough

After the dough has been chilling for 1-2 hours (or longer if you’ve prepped ahead), take it out of the fridge. Let it sit on the counter for a few minutes to soften slightly, making it easier to roll.

On a lightly floured surface , or if you prefer a cleaner setup, between two pieces of parchment paper , roll the dough out to ⅛ or ¼-inch thickness (3-5mm) . The parchment paper trick helps prevent sticking without adding too much extra flour—which can toughen the dough.

Cutting the Cookies

Using your 2-inch (5cm) round or fluted cookie cutter, cut out as many circles as possible from the rolled dough. Keep gathering and rerolling the scraps as needed, but remember not to overwork the dough—doing so could make the cookies harder than desired. You’re aiming for about 24 cookies to form 12 sandwich pairs .

Optional Step: Chill Before Baking

At this point, if your dough has warmed up too much while rolling and cutting, place the unbaked cookies (arranged neatly on baking sheets lined with parchment paper ) into the freezer or fridge for about 15 minutes . This chilling time firms up the dough again and reduces the chances of spreading during baking, so the cookies retain their lovely, neat shape.

Prepping the Oven

Meanwhile, preheat your oven to 350℉ (177℃) . A properly preheated oven ensures that the cookies bake evenly.

Baking the Cookies

Once the dough is nicely chilled again and the oven is hot, place the baking sheets in the oven. Bake the cookies for 7-10 minutes , keeping an eye on them. The cookies should be pale on the top but just starting to turn golden around the edges —that’s your signal they’re ready!

Pro Tip: Alfajores are known for being soft and delicate, so don’t let them get too dark. Err on the side of caution if needed, and keep a close watch toward the 7-minute mark.

Cooling the Cookies

After baking, let the cookies cool directly on the baking sheet for about 10 minutes —they’ll be too fragile to handle right away. Then, carefully transfer them to a wire cooling rack to cool completely. This helps prevent them from becoming soggy on the underside.

Assembling the Alfajores

With the cookies perfectly baked and fully cooled, it’s time to assemble these delightful sweet sandwiches. This step really brings out the magic—the combination of tender biscuits with the creamy, rich dulce de leche is what makes alfajores irresistible!

Assembling the Alfajores

Filling the Cookies

Now for the fun part! Grab your dulce de leche (about 12 oz/350g) . You can use store-bought dulce de leche, or if you’re feeling ambitious, you can make your own beforehand by slowly caramelizing sweetened condensed milk. Either way, make sure the dulce de leche is at room temperature; this makes it easier to spread.

To assemble:

  1. Spread the Dulce de Leche : Take a spoonful of dulce de leche (about a teaspoon for each cookie) and carefully spread it over the bottom side of one of the cookies. Be generous here, ensuring there’s enough to create a delightful ooze when you sandwich them.
  2. Sandwich Together : Place a second cookie on top, bottom side down, and gently press the cookies together. Don’t press too hard—just enough to secure the filling. You want the dulce de leche to peek out a bit from the edges!

Rolling in Coconut

Now it’s time to coat the edges of the alfajores in coconut. Prepare ½ cup of unsweetened shredded or desiccated coconut for this step.

To finish assembling:

  1. Rolling the Edges : Once the cookies are sandwiched together, roll the edges (where the dulce de leche is slightly oozing out) in the shredded coconut. The coconut will stick to the filling perfectly, adding a subtle flavor and texture that compliments the cookies beautifully.

Pro Tip: If you’re not a fan of coconut, don’t worry! You can leave this step out, or even replace the coconut with chopped nuts, if you prefer. Keep it customizable to your tastes.

Once that’s done, marvel at your beautiful alfajores sandwich cookies! They’re now ready to enjoy, but like with all good things, a little patience might make them even better. Tip: letting the cookies sit for a few hours or overnight allows the flavors to meld even more!

Storing and Serving the Alfajores

Now that you’ve assembled your beautiful alfajores, you might want to know how to keep them fresh (if they even last that long) or the best way to serve them for any occasion. These cookies, though delicious immediately, often taste even better after resting for a while.

Serving the Alfajores

Serving Suggestions

Alfajores are quite versatile, making them a wonderful addition to any event. Here are a few ways to elevate your serving style:

  • Classic Style : Simply serve them as they are—delicate, filled with dulce de leche, and coated in coconut. A winning combination every time.
  • With Coffee or Tea : Alfajores pair wonderfully with a warm cup of coffee or tea. Their buttery, crumbly texture and sweet filling are the perfect companions to a warm drink.
  • Dusted with Powdered Sugar : For an extra touch of elegance, lightly dust the alfajores with powdered sugar just before serving.
  • At Parties or Gatherings : Alfajores make fantastic party treats. Arrange them on a beautiful platter and watch them disappear as quickly as you set them down. These cookies always impress, especially when made from scratch!

Storage Instructions

If you somehow have leftovers (which isn’t always the case!), here’s how to store them so you can enjoy them for days, or even weeks, to come.

Storing at Room Temperature

Your freshly baked alfajores can be stored at room temperature for up to 7 days as long as they’re kept in an airtight container . The cookies may soften a bit as they absorb moisture from the dulce de leche, but that’s precisely what makes them even better!

Storing the Alfajores

Refrigerating

If you prefer, you can also store alfajores in the fridge, especially if your home tends to be warm. Refrigerating them will make the cookies firmer, but always store them in an airtight container to avoid them drying out. You can still enjoy them for up to one week this way.

Freezing Alfajores

Need to store them longer? Freeze , don’t fret! Alfajores freeze beautifully:

  1. Place the cookies in a freezer-safe bag or container . Make sure to separate layers with parchment paper to prevent them from sticking together.
  2. They can be frozen for up to 2 months without losing quality.

When you’re ready to enjoy them again, simply thaw them at room temperature or even pop them in the fridge overnight to gradually thaw. Alfajores taste just as delicious when they’re brought back to life after freezing—they might even gain a slightly chewier texture!
