Ingredients You’ll Need
Gathering the right ingredients might be the simplest yet most crucial part of this Dulce de Leche Cinnamon Sandwich Cookies Recipe. Each item plays a special role, whether it’s building that soft cookie base, infusing warm cinnamon spice, or creating a luscious filling that ties it all together.
- All-purpose flour: The sturdy foundation that gives your cookies their tender crumb.
- Ground cinnamon: Adds warm, fragrant spice that pairs perfectly with the dulce de leche.
- Baking soda: A gentle leavening agent to keep your cookies light and soft.
- Salt: Balances sweetness and enhances overall flavor.
- Unsalted butter: Both in cookies and filling, it provides rich flavor and creamy texture.
- Brown sugar: Gives moisture and a subtle caramel undertone to the cookie dough.
- Egg: Binds ingredients together while adding tenderness.
- Vanilla extract: Deepens the sweetness with warm, aromatic notes.
- Granulated sugar: For rolling the cookie dough balls, it adds a delicate crunch and sparkle.

How to Make Dulce de Leche Cinnamon Sandwich Cookies Recipe
Step 1: Prepare the Dough
Begin by whisking together the dry ingredients: flour, cinnamon, baking soda, and salt. Separately, cream the softened butter and brown sugar until the mixture becomes light and fluffy. Then, beat in the egg and vanilla extract until smooth. This step ensures your dough will be perfectly tender and flavorful.
Step 2: Combine Wet and Dry Ingredients
Slowly add the dry mixture to the wet, mixing just until fully combined. The goal here is a soft dough that holds together easily but isn’t sticky, meaning your cookies will have just the right structure without being tough.
Step 3: Chill the Dough
Wrap your dough tightly in plastic wrap and pop it in the fridge for at least 30 minutes. Chilling is essential—it allows the flour to hydrate fully and the butter to firm up, which in turn helps the cookies hold their shape while baking without spreading too much.
Step 4: Preheat the Oven
As your dough chills, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Prepare your baking sheets by lining them with parchment paper or silicone baking mats to prevent sticking and ensure even baking.
Step 5: Shape the Cookies
Roll the dough into approximately 1-inch balls, then give each a gentle roll in granulated sugar. This exterior sugar coating will give your cookies a delightful sparkle and light crunch. Place them on the prepared baking sheets, spacing them about 2 inches apart, and gently flatten each ball with the back of a spoon for even cookies.
Step 6: Bake
Bake your cookies for 8 to 10 minutes, looking for light golden edges as your cue that they’re ready. Let them cool briefly on the baking sheet before transferring to a wire rack. Cooling completely here is key since the cookies need to be firm enough to sandwich without breaking.
Step 7: Make the Filling
In a small bowl, beat together the dulce de leche, softened butter, and vanilla extract until luxuriously smooth and creamy. This luscious filling adds a rich, caramel layer of flavor that perfectly complements the cinnamon-spiced cookie.
Step 8: Assemble the Sandwich Cookies
Once your cookies are cool, generously spread the dulce de leche filling on the flat side of one cookie. Top with a second cookie to form a sandwich. Repeat this process until all cookies are paired up. Trust me, it’s almost too hard to wait for them to set before diving in!
Step 9: Serve and Enjoy
Let the sandwiches sit for a few minutes to allow the filling to set slightly. Then, dig in and savor each bite of your homemade Dulce de Leche Cinnamon Sandwich Cookies Recipe. Every mouthful offers a perfect blend of soft cinnamon cookie and creamy dulce de leche that’s simply irresistible.

Garnishes
To give your cookies a stunning final touch, consider dusting them lightly with cinnamon sugar or a sprinkle of powdered sugar. These simple garnishes add visual appeal and an extra hint of sweetness that will delight anyone lucky enough to try them.
Side Dishes
These sandwich cookies pair wonderfully with a warm beverage. A cup of spiced chai, hot cocoa, or even a rich espresso complements the cinnamon and caramel flavors beautifully, creating a cozy treat perfect for afternoon indulgence or festive gatherings.
Creative Ways to Present
For an extra-special presentation, arrange your Dulce de Leche Cinnamon Sandwich Cookies Recipe on a rustic wooden board surrounded by cinnamon sticks, coffee beans, or a scattering of edible flowers. You can also stack them in a pretty tin or wrap them individually with twine for a charming gift idea.
Make Ahead and Storage
Storing Leftovers
Keep any leftover sandwich cookies in an airtight container at room temperature for up to 3 days. This allows them to maintain their texture and the filling to stay creamy without drying out.
Freezing
If you want to prepare these in advance, assemble the cookies and freeze them in a single layer on a baking sheet. Once frozen, transfer them to a freezer-safe container or bag. They will keep well for up to 2 months and thaw quickly for anytime enjoyment.
Reheating
To bring back the fresh-baked warmth, briefly microwave the cookies for about 10 seconds. This softens the filling and warms the cookies, recreating that just-baked bliss without making them soggy.
FAQs
Can I make the dulce de leche filling from scratch?
Absolutely! You can make homemade dulce de leche by slowly simmering sweetened condensed milk until it caramelizes, or by baking a can of condensed milk in a water bath. Both methods give a rich, homemade touch to your filling.
Are these cookies gluten-free friendly?
Since this recipe uses all-purpose flour, it’s not gluten-free as is. However, you could experiment with gluten-free flour blends, but be aware that texture and flavor may vary slightly.
What’s the best way to soften the butter?
Simply leave the butter out at room temperature for about 30 minutes until it’s soft but not melted. This helps it cream smoothly into the sugar, which is vital for a tender cookie.
Can I substitute other spices for cinnamon?
You could try warming spices like nutmeg, allspice, or cloves for a different flavor twist. Cinnamon, however, gives this recipe its signature cozy note that pairs perfectly with dulce de leche.
How long will the cookies stay fresh?
Stored properly in an airtight container, these sandwich cookies will stay fresh for up to 3 days at room temperature. For longer storage, freezing is your best bet.
