What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and substitutions work well if you need to swap some out.

• For the Alfajores Cookies:
  • 1 cup (225g) unsalted butter, softened (adds richness and tenderness)
  • 3/4 cup (150g) granulated sugar
  • 2 large egg yolks, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 cups (250g) all-purpose flour
  • 1 cup (120g) cornstarch (key for that melt-in-your-mouth texture)
  • 1 teaspoon baking powder
  • Pinch of salt
• For the Filling:
  • 1 cup (320g) dulce de leche (store-bought or homemade – I love using La Lechera brand for smoothness)
• Optional Coating:
  • Powdered sugar for dusting
  • Desiccated coconut for rolling the edges

Looking for gluten-free? Swap the all-purpose flour with a gluten-free blend and reduce cornstarch slightly. For a dairy-free version, use coconut oil instead of butter and check your dulce de leche choice or make a coconut milk caramel.

Equipment Needed

• Mixing bowls (one large for dough, one for wet ingredients)
• Electric mixer or stand mixer with paddle attachment (for creaming butter and sugar smoothly)
• Sifter or fine mesh sieve (to aerate flour and cornstarch)
• Rolling pin (a small one works great for this dough)
• Cookie cutters (round, about 2 inches/5 cm diameter)
• Baking sheets lined with parchment paper or silicone mats
• Spatula and spoon for mixing and spreading dulce de leche

If you don’t have a mixer, no worries—hand beating works, but be ready for a bit of an arm workout. A silicone spatula is my favorite tool for folding in dry ingredients gently. For budget-friendly options, a simple hand whisk and sturdy bowl will do just fine.

Preparation Method

1. Cream the Butter and Sugar: In a large bowl, beat 1 cup (225g) softened unsalted butter with 3/4 cup (150g) granulated sugar until pale and fluffy, about 3-4 minutes. This step is crucial for tender cookies, so don’t rush it.
2. Add Egg Yolks and Vanilla: Mix in 2 large egg yolks, one at a time, then stir in 2 teaspoons vanilla extract until combined. The dough will look silky and smooth.
3. Combine Dry Ingredients: Sift together 2 cups (250g) all-purpose flour, 1 cup (120g) cornstarch, 1 teaspoon baking powder, and a pinch of salt. Gradually add to the wet mixture, mixing just until you have a soft dough. Be careful not to overmix—otherwise, the cookies may turn tough.
4. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes. This helps the dough firm up and makes rolling easier.
5. Roll and Cut: Preheat the oven to 350°F (175°C). On a lightly floured surface, roll the dough to about 1/4 inch (6mm) thickness. Use a 2-inch (5 cm) round cookie cutter to cut out shapes. Place them on parchment-lined baking sheets, leaving space for gentle spreading.
6. Bake the Cookies: Bake for 10-12 minutes, until the edges are just set but not browned. The tops should look matte and slightly soft to the touch—not crispy. Let them cool completely on wire racks.
7. Assemble the Alfajores: Spread about 1 tablespoon (15g) of dulce de leche on the flat side of one cookie, then sandwich it with another. For a classic finish, roll the edges in desiccated coconut or dust with powdered sugar.

If the dulce de leche is too thick, warm it gently in a bowl over hot water to soften. If you notice your cookies spreading too much in the oven, chill the cut dough for another 10 minutes before baking next time. The smell of these cookies baking honestly feels like a warm hug in your kitchen.

Cooking Tips & Techniques

For tender alfajores cookies, the key is handling the dough gently—overworking flour can develop gluten, making cookies tough. Use cornstarch as your secret weapon; it lightens the flour mixture, creating that signature melt-in-your-mouth texture.

Another tip: room temperature butter creams more evenly with sugar, trapping air for fluffiness. If your kitchen is warm, chill the dough longer to avoid spreading.

Don’t skip chilling the dough—that’s a game-changer for rolling and baking consistency. When spreading dulce de leche, use a butter knife or offset spatula for a smooth, even layer without breaking the cookies.

Trust me, the first time I skipped chilling, the cookies ran all over the pan and tasted more like a buttery crisp than a tender treat. Lesson learned! Also, baking just until the edges set is crucial; overbaking dries them out.

Variations & Adaptations

This recipe is wonderfully adaptable, so feel free to mix things up:

• Chocolate Alfajores: Add 2 tablespoons unsweetened cocoa powder to the dry ingredients for a chocolate twist. Pair with dulce de leche or try a chocolate ganache filling.
• Gluten-Free Version: Use a gluten-free flour blend and reduce cornstarch to 3/4 cup (90g). The cookies remain tender and just as delicious.
• Fruit-Filled Variation: Swap out dulce de leche for raspberry jam or lemon curd for a fruity surprise. This brightens up the cookie and adds a fresh tang.

For a vegan take, substitute butter with coconut oil and use a plant-based dulce de leche or homemade caramel made with coconut milk. I tried almond flour once, and while it was tasty, the texture was a bit denser—still a nice change if you like a chewier cookie.

Serving & Storage Suggestions

Serve tender alfajores cookies at room temperature, ideally alongside a steaming cup of coffee or tea to bring out their buttery richness. Dust them with extra powdered sugar just before serving for a pretty presentation that feels festive.

Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, pop them in the fridge wrapped well; they keep for up to a week but might firm up slightly. To freeze, place sandwiches in a single layer on a baking sheet, freeze until solid, then transfer to a freezer bag for up to 2 months.

Reheat frozen alfajores gently at room temperature or warm briefly in a low oven (250°F/120°C) for 5 minutes to bring back softness. Over time, the dulce de leche filling melds beautifully with the cookies, making them even more luscious the next day.

Nutritional Information & Benefits

A serving of two alfajores cookies with dulce de leche (about 60g) contains approximately 250 calories, with moderate amounts of fat and sugar. The use of butter provides essential fat-soluble vitamins, while the cornstarch keeps the cookies light.

Dulce de leche, made from sweetened condensed milk, offers a rich source of calcium and protein, though it’s a treat best enjoyed in moderation due to sugar content. For those mindful of dietary needs, this recipe can be adjusted to gluten-free or dairy-free versions without losing its soul.

Honestly, these cookies feel like a little wellness indulgence—comfort food that also brings joy and connection to family traditions, which is just as nourishing.
