Ingredients You’ll Need

These ingredients come together beautifully to create a cookie dough that’s easy to work with and a filling that’s irresistibly creamy. Each one plays a key role—from the buttery base to the soft dulce de leche filling. When shopping, I recommend finding a good-quality dulce de leche; you can buy it or make it at home if you like DIY challenges.

• All-purpose flour: Provides structure and gives these cookies that classic tenderness.
• Cornstarch: Key for that melt-in-your-mouth softness — don’t skip it!
• Baking powder: Just a pinch to help the cookies rise lightly and stay airy.
• Salt: Balances the sweetness and enhances flavor.
• Unsalted butter: Softened, for creaminess and richness—room temperature works best.
• Granulated sugar: Sweetens and helps create that delicate crumb.
• Egg yolks: Adds moisture and richness—save those whites for meringues or another treat!
• Pure vanilla extract: Brings warmth and depth to the flavor.
• Dulce de leche: The star of the show—creamy, smooth, and irresistibly sweet.
• Desiccated coconut: Gives a lovely, slightly chewy contrast on the edges and a pretty finish.

Variations

I love making these heart sandwich cookies just as they are, but over time I’ve found a few fun tweaks that make them even more special. Don’t hesitate to get creative and make this recipe your own—you’ll find that changing up the filling or the coating is a simple way to delight your taste buds or accommodate guests’ preferences.

• Chocolate-Dipped Edges: One of my favorite twists is dipping half of each filled cookie in melted dark chocolate—adds a beautiful contrast and extra indulgence.
• Nutty Texture: Swap the desiccated coconut for finely chopped toasted nuts like almonds or pistachios for a crunchy edge your family will adore.
• Flavor Variations: I’ve stirred a little orange zest into the dough or sprinkled cinnamon on top before baking for a seasonal twist.
• Diet-Friendly: You can experiment with gluten-free flour blends to make a version for gluten-sensitive folks, just be mindful the texture may differ slightly.

How to Make Heart Sandwich Cookies with Dulce de Leche Recipe

Step 1: Whisk Together the Dry Ingredients

Start by sifting the all-purpose flour, cornstarch, baking powder, and salt in a small bowl. Sifting keeps the flour light and helps ensure there are no lumps, which makes mixing easier later on. Trust me, this little extra step makes a visible difference in your cookie texture.

Step 2: Cream Butter and Sugar

In a large mixing bowl, beat the softened unsalted butter and granulated sugar together until the mixture is light and fluffy. This usually takes about 3-5 minutes with an electric mixer on medium speed. The air you whip in here creates lightness in your cookies—don’t rush it! Then, add egg yolks one at a time, blending well after each addition, and stir in the vanilla extract for that beautiful aroma.

Step 3: Combine Wet and Dry to Form Dough

Gradually fold in your dry ingredients to the butter mixture using a spatula or your hands. The dough will come together nicely without being sticky. If it feels a bit soft, no worries—that softness helps keep the cookies tender. Once it forms a smooth dough, divide it in half, wrap each portion in plastic wrap, and chill in the fridge for at least an hour. This step is crucial for easy rolling and cutting later.

Step 4: Roll and Cut Your Hearts

Preheat your oven to 350°F (175°C, Gas Mark 4). Line two baking sheets with parchment paper. Roll out one chilled dough portion between two sheets of parchment paper to about 1/4-inch thickness—this keeps it from sticking or tearing. Then grab your heart-shaped cookie cutter and start pressing out these cute shapes. Place the hearts on your baking sheets, leaving small spaces so they don’t stick together.

Step 5: Bake Until Just Golden

Bake the hearts for 8 to 10 minutes, watching closely so they turn only slightly golden around the edges. You want them to look a little pale overall and still soft, as they firm up while cooling. Overbaking means dry, crumbly cookies, so set your timer and check early if your oven runs hot!

Step 6: Cool Completely Before Sandwiching

Let the cookies cool on the baking sheets for a few minutes, then transfer them to a wire rack to cool completely. Warm cookies will melt the dulce de leche filling and make assembling a mess. Patience here really pays off for neat and beautiful sandwich cookies.

Step 7: Assemble with Dulce de Leche and Coconut

Spread about a tablespoon or so of dulce de leche on the flat side of one cookie, then sandwich it with another heart cookie. Roll the edges of each sandwich in desiccated coconut to coat evenly. It’s a bit sticky but the coconut clings nicely, adding texture and a lovely flavor contrast.

Step 8: Let Them Set

Place your coconut-coated sandwiches on a tray and let them rest at room temperature for at least an hour. This helps the filling firm up and the flavors meld. Then, you’re ready to enjoy—or share with those lucky enough to have one!

How to Serve Heart Sandwich Cookies with Dulce de Leche Recipe

Garnishes

While a simple dusting of powdered sugar can look pretty, I usually stick with the desiccated coconut coating because it adds a nice texture and keeps the edges from sticking together. Sometimes, I like sprinkling a tiny pinch of flaky sea salt on the dulce de leche before sandwiching to add a subtle pop of flavor—so good!

Side Dishes

These cookies pair beautifully with a warm cup of tea or coffee—my go-to is a rich latte or chai. For a festive party, I like serving them alongside fresh berries or a vanilla ice cream scoop for a fun dessert spread.

Creative Ways to Present

When making these for Valentine’s Day or anniversaries, I’ve arranged them in a heart shape on a pretty platter covered with rose petals for a romantic touch. They also make adorable homemade gifts—wrap a few in parchment paper tied with twine and a sprig of greenery for a thoughtful, edible present.

Make Ahead and Storage

Storing Leftovers

I store leftover cookies in an airtight container at room temperature, and they stay amazingly fresh for up to 4 days. The dulce de leche softens the cookies slightly over time, which some people actually prefer as it makes them even more tender.

Freezing

If you want to prep in advance, you can freeze the baked cookies (before sandwiching) wrapped tightly in plastic wrap and placed in freezer-safe bags for up to 2 months. When ready to assemble, thaw them at room temperature, then sandwich with dulce de leche and roll in coconut.

Reheating

These cookies are best enjoyed at room temperature, but if you want to warm them slightly, I gently heat the assembled cookies in a low oven (about 250°F) for just a few minutes to soften the filling—perfect for chilly days!
