Ingredients You’ll Need

I’ve found that using both all-purpose flour and cornstarch is what gives these cookies their beautiful, melt-in-your-mouth consistency. The rest of the ingredients are straightforward, but a couple of handy tips can make all the difference in your baking success.

• All-purpose flour: Sifting is key here to make sure your dough is smooth and free of lumps.
• Cornstarch: Helps keep the cookies ultra-soft and tender—don’t skip this!
• Baking powder: Just a tiny bit helps the cookies rise gently without puffing up too much.
• Salt: Balances the sweetness and enhances the buttery flavor.
• Unsalted butter: Make sure it’s softened to room temperature for easy creaming.
• Granulated sugar: Adds that subtle sweetness and crunch when creamed with butter.
• Egg yolks: I love that these, instead of whole eggs, make the cookies richer and give a tender crumb.
• Pure vanilla extract: A small splash elevates the overall flavor beautifully.
• Dulce de leche: This is the star of your filling—whether store-bought or homemade, use a good quality one for best results.
• Desiccated coconut: It’s perfect for rolling the edges to add texture and keep things looking pretty.

Variations

I often like to experiment with these heart sandwich cookies depending on who I’m baking for or the occasion. It’s a flexible recipe that can handle sweet twists or even some dietary tweaks.

• Nutty Touch: My family goes crazy when I add finely chopped nuts like pecans or almonds inside the dough or sprinkle on top for extra crunch.
• Chocolate Lover’s Version: Mixing a bit of cocoa powder into the dough for a chocolatey twist pairs wonderfully with the dulce de leche.
• Gluten-Free: I’ve tried substituting with a gluten-free flour blend, which works well—just watch your dough consistency.
• Seasonal Flavors: Sometimes I add a pinch of cinnamon or orange zest to the dough to give it a warm seasonal note.

How to Make Heart Sandwich Cookies with Dulce de Leche Recipe

Step 1: Sifting and Mixing Your Dry Ingredients

Start by sifting together your all-purpose flour, cornstarch, baking powder, and salt. Sifting helps keep everything airy and spot-on in texture. I like doing this step first because it makes the dough come together so much smoother later on.

Step 2: Cream Butter and Sugar Until Fluffy

In a large bowl, beat the softened butter and sugar until the mixture is light and fluffy—this usually takes about 3 to 4 minutes with a hand mixer. This step is crucial because that fluffiness translates into tender cookies.

Step 3: Add Egg Yolks and Vanilla

Next, add the egg yolks one at a time, mixing well after each addition. Then stir in the vanilla extract. Using yolks only helps keep the dough rich and smooth without adding too much moisture.

Step 4: Combine Dry and Wet Ingredients

Gradually add your sifted dry ingredients to the butter mixture. I usually switch to a spatula here and then gently knead with my hands once it’s starting to come together. You want a soft dough that’s not sticky but holds its shape.

Step 5: Chill the Dough

Divide your dough into two portions, wrap them in plastic wrap, and pop them in the fridge for at least an hour. Chilling helps the dough firm up, making it much easier to roll out and cut.

Step 6: Roll and Cut Your Heart Shapes

Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper. Roll each dough portion between two sheets of parchment paper to about a 1/4-inch thickness—this keeps cleanup easier and prevents sticking. Use a heart-shaped cookie cutter to cut out cookies, then place them spaced out on your sheets.

Step 7: Bake Until Edges Are Lightly Golden

Bake for 8 to 10 minutes. Keep an eye on them—the edges should turn a soft golden color but the cookies will still look pale overall. This ensures they stay tender and don’t get too crisp. Remove and allow to cool for a few minutes on the baking sheet before transferring to a wire rack.

Step 8: Assemble Your Heart Sandwich Cookies

Once cookies are completely cool, spread a generous spoonful of dulce de leche on the flat side of one cookie, then sandwich it gently with another cookie. Don’t skimp on the filling—you want that rich caramel flavor to shine through every bite.

Step 9: Roll Edges in Coconut

To finish, roll the edges of the sandwich cookies in desiccated coconut. This adds beautiful texture and a little crunchy contrast that I actually look forward to—it also keeps the dulce de leche from sticking to everything!

Step 10: Let Them Set Before Serving

Let your adorable heart sandwich cookies rest on a tray or plate for at least an hour. This step really helps the flavors meld together and keeps everything intact when you serve—and it builds anticipation, trust me!

How to Serve Heart Sandwich Cookies with Dulce de Leche Recipe

Garnishes

I usually keep it simple by rolling the edges in coconut, but sometimes I sprinkle a little powdered sugar on top right before serving for a snowy finish that’s just so pretty. If I want a festive touch, a few tiny edible gold sprinkles make these cookies feel extra special.

Side Dishes

These cookies pair wonderfully with a warm cup of tea or coffee, especially something robust like a dark roast or chai. For parties, I love serving them alongside fresh berries or a light fruit salad to balance the sweetness.

Creative Ways to Present

If I’m gifting these or serving at a special occasion, I like arranging them in a pretty box lined with parchment paper, layering the cookies gently so they don’t stick. For Valentine’s Day, placing them on a heart-shaped platter definitely steals the show!

Make Ahead and Storage

Storing Leftovers

I keep leftover alfajores in an airtight container at room temperature for up to 3 days. The cookies stay beautifully soft, and the filling gets even more luscious as it sits—a happy bonus!

Freezing

I’ve frozen both unfilled cookies and assembled alfajores. For unassembled dough, wrap tightly and freeze for up to a month, then thaw overnight in the fridge before rolling out. Assembled cookies freeze well wrapped individually in plastic wrap and placed in a sealed container, though I recommend thawing them in the fridge overnight to preserve texture.

Reheating

While these cookies are best enjoyed at room temperature, if you want to freshen them up, a few seconds in the microwave (10-15 sec) softens the dulce de leche inside without melting the cookie. Just be careful not to overheat or they’ll get too soft.
