Ingredients You’ll Need

These ingredients all come together to create that tender, melt-in-your-mouth cookie with the gooey dulce de leche filling that makes alfajores unmistakable. I recommend using real unsalted butter for the best flavor and quality dulce de leche—homemade if you can swing it!

• Unsalted Butter: Softened butter is key for that tender crumb and buttery flavor your cookies need.
• Powdered Sugar: This helps keep the dough soft and sweet without any gritty texture.
• Light Brown Sugar: Adds a slight caramel note that complements the dulce de leche beautifully.
• Cornstarch: Helps create that wonderfully delicate, melt-away texture in the cookies.
• Vanilla Extract: A splash of vanilla brightens the entire flavor profile.
• Salt: Just enough to balance the sweetness and enhance other flavors.
• All-Purpose Flour: The base of the cookie dough, use fresh for best results.
• Dulce de Leche: The star filling—rich, creamy, and utterly addictive! Homemade is best, but store-bought works great, too.
• Desiccated Coconut (optional): Rolling the filled edges in coconut adds a lovely texture and a fresh bite.
• Powdered Sugar (optional): A dusting on top makes for a pretty and classic finish.

Variations

I love experimenting with alfajores, and you’ll find that tweaking fillings or coatings can make the cookie your own. Whether you prefer a chocolate drizzle or a sprinkle of cinnamon, these little sandwiches take well to personal touches.

• Chocolate-Dipped Alfajores: I once dipped half the cookie in melted dark chocolate—such a lovely contrast of flavors and textures!
• Gluten-Free Version: You can swap in gluten-free flour blends, but be sure to add a little extra cornstarch for that tender texture.
• Nutty Fillings: Sometimes I mix crushed nuts into the dulce de leche for extra crunch and flavor.
• Flavored Dulce de Leche: Adding a pinch of cinnamon or a splash of orange zest to the filling really amps up the flavor profile.

How to Make Alfajores: Sweet Dulce de Leche Sandwich Cookies Recipe

Step 1: Cream Your Butter and Sugars

Start by beating the softened unsalted butter alone until it’s smooth and creamy—this usually takes about 2-3 minutes with an electric mixer. Then, add both the powdered sugar and light brown sugar, along with cornstarch, vanilla extract, and salt. Beat everything together until your mixture is light, fluffy, and well combined. This step is crucial to achieving that soft, melt-in-your-mouth texture that alfajores are known for.

Step 2: Gently Incorporate the Flour

Gradually stir in the all-purpose flour in about four additions. I like to mix it in slowly to avoid overworking the dough, which keeps those cookies tender. Once the flour is incorporated, divide your dough into two disks and wrap each in plastic wrap. Refrigerate for at least 30 minutes — or up to 5 days if you want to prep ahead. This resting time firms up the dough, making it easier to roll and cut.

Step 3: Roll and Cut the Cookies

Dust your work surface lightly with flour and roll out one disk at a time to about ⅛ inch thick. I recommend using a 1 ¾-inch round cookie cutter, but a 2-inch works beautifully, too. Make sure your cookies are spaced at least an inch apart on the parchment-lined baking sheet so they bake evenly and don’t stick together.

Step 4: Bake Until Just Golden

Bake your cookies in a preheated 375°F (190°C) oven for 8-9 minutes. The trick is to watch the edges—they should just begin to turn lightly golden but not brown. Over-baked alfajores lose that signature softness, so keep an eye here! Let them cool fully on the baking sheet before handling to avoid breakage.

Step 5: Assemble Your Alfajores

Spread about 1 ½ teaspoons of dulce de leche on the flat side of a cookie, then sandwich it with another cookie. For extra flair, gently press the edges of the sandwich into desiccated coconut—it sticks best if you squeeze the cookie gently so the filling peeks out. Alternatively, dust the tops with powdered sugar for a beautiful finish. And voilà, your alfajores are ready to enjoy!

How to Serve Alfajores: Sweet Dulce de Leche Sandwich Cookies Recipe

Garnishes

My favorite way to finish these cookies is by rolling the edges in desiccated coconut. It adds such a lovely texture and a subtle tropical note that cuts through the sweetness. If you want to keep things simple, a light dusting of powdered sugar is classic and pretty. For a more decadent twist, a drizzle of melted chocolate never disappoints!

Side Dishes

Alfajores pair beautifully with a hot cup of coffee or tea — especially a strong black coffee which balances the sweetness. I’ve also enjoyed them alongside fresh berries or a scoop of vanilla ice cream when serving as a dessert treat.

Creative Ways to Present

For special occasions, I like arranging alfajores on a decorative platter with edible flowers or fresh mint leaves. Layering them in a clear glass jar for gifting also looks charming and lets the recipient see that beautiful, irresistible filling. If you’re feeling festive, sprinkle edible glitter over the powdered sugar for a sparkling touch.

Make Ahead and Storage

Storing Leftovers

These cookies keep best in an airtight container at room temperature for up to 3 days. The buttery cookie stays tender, and the dulce de leche remains luscious — I find the flavors actually deepen as they rest!

Freezing

If you want to freeze alfajores, I recommend assembling them first, then placing them in a single layer on a baking sheet until firm, before transferring to a sealed freezer bag. They freeze well for up to 2 months and thaw beautifully at room temperature.

Reheating

Because alfajores are best enjoyed at room temperature, I usually let frozen cookies thaw naturally. If you’re feeling impatient, a few seconds in the microwave (wrapped in a paper towel) can soften them up—but watch carefully so you don’t melt the dulce de leche completely.
