Step‑by‑Step Instructions for Dulce de Leche Cinnamon Sandwich Cookies
Step 1: Prepare the Cookie Dough
In a large mixing bowl, cream together 1 cup of softened unsalted butter and 1 cup of granulated sugar using a hand mixer on medium speed for about 3 minutes, or until the mixture is fluffy and light. Next, beat in 1 large egg and 1 teaspoon of vanilla extract until fully combined. Gradually add the dry ingredients—2 cups all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt—mixing until a dough forms.
Step 2: Chill Dough
Once your dough is ready, wrap it tightly in plastic wrap and refrigerate for 10-15 minutes. This step is crucial for helping the dough firm up, thus preventing the cookies from spreading too much during baking. While waiting, preheat your oven to 350°F (175°C) for the perfect baking environment for your Dulce de Leche Cinnamon Sandwich Cookies.
Step 3: Coat Dough Balls
After chilling, take tablespoon-sized portions of the dough and roll them into smooth balls between your hands. In a separate bowl, combine 1/4 cup of granulated sugar with 1 tablespoon of ground cinnamon. Roll each dough ball in this cinnamon-sugar mixture until coated evenly—this adds a delightful sweetness and spice to each cookie!
Step 4: Bake Cookies
Place the coated dough balls on a lined baking sheet, spacing them about 2 inches apart. Bake in your preheated oven for 9-11 minutes, or until the edges turn golden brown while the centers remain soft. You want a slight puff but not a dry bake. Once done, remove them and let the cookies cool on the baking sheet for a few minutes.
Step 5: Cool
Carefully transfer the baked cookies to a wire rack to cool completely. This cooling process ensures the cookies harden slightly while retaining their soft, chewy texture. It’s important to wait until they’re cooled before moving to the filling stage, as warm cookies could melt the dulce de leche.
Step 6: Prepare Filling
To create the luscious filling, take 1/4 cup of unsalted butter and melt it in a microwave-safe bowl. Mix in 1 cup of dulce de leche until smooth and creamy, ensuring all ingredients are thoroughly combined. This step is key for a silky filling that spreads nicely between the cookies.
Step 7: Assemble Sandwiches
Take one cooled cookie and generously spread a layer of the dulce de leche filling on the flat side. Top it with another cookie, pressing gently to form a sandwich. Repeat with the remaining cookies. For the best experience, let the assembled sandwiches rest for about 1 hour so the flavors meld beautifully.

Chill the Dough Properly: A well-chilled dough maintains its shape while baking, preventing overly flat cookies. Don’t skip this important step!

Dulce de Leche Cinnamon Sandwich Cookies Recipe FAQs
How do I choose ripe ingredients for these cookies?
Absolutely! For the best flavor, select soft, unsalted butter at room temperature to ensure it mixes well with sugar. Eggs should be fresh and at room temperature for the best binding results. Using fluffy, good-quality vanilla extract will enhance the taste, making every bite dreamy.
How should I store leftover cookies, and how long do they last?
Very! To keep your cookies fresh, store them in an airtight container at room temperature for up to 7 days. If you’re storing them in the fridge, they can last up to 5 days, but be sure to bring them back to room temperature before enjoying! For longer storage, consider freezing them.
Can I freeze Dulce de Leche Cinnamon Sandwich Cookies?
Yes, you can! Wrap each sandwich cookie tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag. They last up to 3 months in the freezer. When you’re ready to indulge, simply thaw them at room temperature or pop them in the microwave for a few seconds to bring the filling back to its gooey glory.
What if my cookie dough is too sticky?
It happens! If you find that your dough is overly sticky, it’s often because the butter wasn’t softened enough, or it’s too warm. Try chilling it for an additional 10 minutes in the refrigerator. If it’s still sticky, you can incorporate a little extra flour, just be careful not to add too much, as it can affect the texture.
Can I make substitutions for dietary restrictions?
Absolutely! If you want a gluten-free version, swap all-purpose flour for gluten-free flour. For dairy-free options, consider using coconut oil or a dairy-free butter alternative. You can also try different fillings, such as vegan caramel or fruit preserves, to cater to various dietary needs while still keeping the essence of these delightful cookies.
Are there allergens I should be aware of?
Yes, it’s essential to consider allergies! The main allergens in these cookies include butter (dairy), eggs, and gluten from the flour.
