Dulce de Leche Sandwich Cookies Ingredients
For the Dulce de Leche
• Sweetened Condensed Milk – Provides sweetness and is essential for the rich flavor of dulce de leche; do not substitute.
For the Cookies
• Vermont Creamery Unsalted Cultured Butter – Adds richness and tenderness; choose high-quality butter for the best results.
• Granulated Sugar – Sweetens the dough; no direct substitutes unless using sugar alternatives.
• Egg Yolks – Contribute moisture and richness; cannot be substituted.
• Vanilla Extract – Enhances flavor; opt for pure vanilla extract for the best taste.
• Corn Starch – Lightens the cookie texture, creating a tender crumb; can be substituted with additional all-purpose flour.
• All-Purpose Flour – Provides structure; for a gluten-free version, use a 1:1 gluten-free baking flour.
• Baking Powder – Adds leavening to the dough; ensure it’s fresh for proper rise.
• Salt – Balances sweetness and enhances overall flavor; do not omit.
Step‑by‑Step Instructions for Dulce de Leche Sandwich Cookies
Step 1: Prepare the Dulce de Leche
Begin by placing an unopened can of sweetened condensed milk in a pot and covering it generously with water. Simmer gently over medium heat for approximately 4 hours, ensuring the can remains submerged in water throughout to prevent bursting. After cooking, carefully remove the can, allow it to cool, then open it and stir in a pinch of salt until blended for a rich and creamy dulce de leche filling.
Step 2: Make the Cookie Dough
In a large bowl, cream together the Vermont Creamery unsalted butter and granulated sugar using an electric mixer until light and fluffy, about 3-4 minutes. Add the egg yolks one at a time, mixing in pure vanilla extract along with each addition. Gradually sift in the cornstarch, all-purpose flour, baking powder, and salt, mixing until you have a soft, cohesive dough that forms a ball.
Step 3: Chill the Dough
Once your cookie dough is well combined, divide it into two equal disks, wrapping each one tightly in plastic wrap. Chill the dough in the refrigerator for 1 hour; this resting period helps the flavors meld and makes rolling out easier later. As it cools, you can preheat your oven to 350°F to prepare for baking.
Step 4: Roll and Cut the Cookies
After chilling, take one disk of dough out of the fridge and roll it out on a floured surface to about 1/8-inch thickness. Use a round cookie cutter to cut out circles, re-rolling scraps as necessary until the dough is used up. Arrange the cookie rounds on a lined baking sheet, spacing them about an inch apart, to allow room for spreading.
Step 5: Bake the Cookies
Slide the baking sheet into the preheated oven and bake the cookies for 8–10 minutes, or until the edges are lightly golden and the centers feel firm to the touch. Keep an eye on them, as you want a tender texture that will remain soft after cooling. Once baked, allow the cookies to cool completely on a wire rack.
Step 6: Assemble the Sandwich Cookies
When your cookies have cooled, flip half of them over and spread about 1 teaspoon of the prepared dulce de leche on the flat side of each cookie. Carefully place the remaining cookies on top, pressing down gently to create a sandwich. Feel free to sprinkle powdered sugar on top for an extra festive touch to your delightful dulce de leche sandwich cookies!
Expert Tips for Dulce de Leche Sandwich Cookies
High-Quality Ingredients: Use premium butter and vanilla extract to enhance the flavor. Cheap ingredients can lead to disappointing results.
Room Temperature Butter: Ensure your butter is at room temperature for easy creaming and a fluffy texture in your cookie dough.
Chill the Dough: Don’t skip chilling; it firms the dough, making it easier to roll out and preventing cookies from spreading too much while baking.
Watch Baking Time: Keep a close eye on the cookies as they bake; overbaking can lead to a dry texture. They should feel soft but set when touched.
Check Dulce de Leche: If your dulce de leche is too thick, add a little warm water to achieve the perfect creamy consistency for spreading between cookies.
Serving Suggestions: Enjoy these dulce de leche sandwich cookies with coffee or hot chocolate for a delightful pairing that enhances the sweet flavors.
How to Store and Freeze Dulce de Leche Sandwich Cookies
Room Temperature: Store cookies in an airtight container at room temperature for up to 1 week. If you’ve assembled them, enjoy within a few days for optimal freshness.
Fridge: For longer storage, place assembled cookies in the refrigerator for up to 2 weeks. Make sure to separate layers with parchment paper to prevent sticking.
Freezer: Freeze unassembled cookies for up to 3 months. Place them in a single layer between parchment paper in an airtight container. Assemble with dulce de leche after thawing.
Reheating: If desired, gently warm cookies in the microwave for a few seconds for a freshly baked feel, but be cautious not to overheat.
Make Ahead Options
These delightful Dulce de Leche Sandwich Cookies are perfect for meal prep! You can prepare the dulce de leche up to 3 days in advance by cooking the sweetened condensed milk and storing it in an airtight container in the refrigerator. The cookie dough can also be made ahead; divide it into disks, wrap tightly, and refrigerate for up to 24 hours. When you’re ready to bake, simply roll out the chilled dough, cut, and bake as directed. For the best quality, assemble the cookies on the day you plan to serve them to prevent sogginess. This way, you’ll enjoy fresh, homemade cookies with minimal effort during busy holiday preparations!

Dulce de Leche Sandwich Cookies (Alfajores) Recipe FAQs
How do I know when my dulce de leche is ready?
Absolutely! After simmering for about four hours, your dulce de leche should have a deep caramel color and a thick, creamy texture. If it seems too thick once cooled, stir in a small amount of warm water to achieve that perfect spreadable consistency.
What are the best ways to store my cookies?
You can store your dulce de leche sandwich cookies at room temperature in an airtight container for up to a week. If you’ve already assembled them, I recommend enjoying them within a couple of days for the freshest flavor. For longer storage, consider refrigerating them, where they will stay good for about two weeks.
Can I freeze these cookies?
Very much so! To freeze unassembled cookies, simply place them in a single layer, separated by parchment paper, inside an airtight container. They will keep well for up to three months. When you’re ready to enjoy, just thaw them and assemble with dulce de leche. It’s a great way to have these treats ready whenever a craving strikes!
What should I do if my cookies spread too much while baking?
If your cookies spread excessively during baking, it could be due to warm butter. Ensure your butter is truly at room temperature before creaming it, and remember that chilling the dough for at least an hour helps too! Next time, consider adding a bit more flour to the dough if needed to maintain that beautiful shape.
Can I substitute any ingredients for dietary reasons?
Certainly! For a gluten-free version of these dulce de leche sandwich cookies, you can use a 1:1 gluten-free baking flour instead of all-purpose flour. Just be sure to check your other ingredients as well, like the vanilla extract and baking powder, to make sure they’re gluten-free as well for safe enjoyment!
