Step‑by‑Step Instructions for Dulce de Leche Cinnamon Sandwich Cookies
Step 1: Prepare the Dough
Begin by creaming together 1 cup of softened unsalted butter and 1 cup of granulated sugar in a mixing bowl until the mixture is light and fluffy, about 2-3 minutes. Next, beat in 1 large egg and 1 teaspoon of vanilla extract. Gradually add 2 cups of all-purpose flour, 1 teaspoon of baking soda, and a sprinkle of salt, mixing until a smooth cookie dough forms.
Step 2: Chill the Dough
To prevent the dough from spreading too much while baking, cover the mixing bowl with plastic wrap and refrigerate the dough for 10-15 minutes. This step is crucial for creating the perfect texture in your Dulce de Leche Cinnamon Sandwich Cookies, allowing for easier handling and shaping later on.
Step 3: Create Cinnamon Sugar
While the dough is chilling, prepare your cinnamon-sugar mixture by combining 1/4 cup of granulated sugar with 2 teaspoons of ground cinnamon in a small bowl. This delightful mixture will provide a crunchy, sweet coating for each cookie, enhancing their flavor and creating a beautiful visual contrast once baked.
Step 4: Form Cookies
Once the dough is chilled, preheat your oven to 350°F (175°C). Shape the chilled dough into 16-24 equal-sized balls, roughly 1 inch in diameter. Roll each ball in the cinnamon-sugar mixture to ensure an even coating and then place them on a lined baking sheet, leaving space between each for spreading during baking.
Step 5: Bake
Bake the cookies in your preheated oven for 9-11 minutes, or until the edges are golden and the centers remain soft. Keep a close eye on them toward the end of the baking time, as they should look slightly puffy. Remove from the oven and allow them to cool on the baking sheet for a few minutes before transferring to a wire rack.
Step 6: Prepare Filling
While your cookies cool, prepare the creamy filling by melting 2 tablespoons of butter in a small saucepan over low heat. Stir in 1 cup of dulce de leche until the mixture is smooth and well-combined. This decadent filling will create that irresistible taste in each sandwich cookie.
Step 7: Assemble Cookies
Once your cookies have cooled completely, take one cookie and spread a generous layer of the dulce de leche mixture on the flat side. Top with another cookie, pressing gently to adhere. Allow the cookie sandwiches to rest for about an hour before serving; this helps the flavors meld together, enhancing the overall experience of your Dulce de Leche Cinnamon Sandwich Cookies.

Expert Tips for Dulce de Leche Sandwich Cookies
-
Chill the Dough: Refrigerate the cookie dough for at least 10-15 minutes to prevent excessive spreading while baking. A chilled dough helps maintain the desired shape.

-
Cooling Time Matters: Make sure to let the cookies cool completely before adding the dulce de leche filling. This prevents the filling from melting and ensures a perfect, creamy sandwich.

Quality Ingredients: Use high-quality unsalted butter and dulce de leche for the best flavor. If making dulce de leche at home, allow it to cool slightly before mixing with butter.
-
Bake in Batches: If you’re making a large batch, consider baking the cookies in separate batches. This ensures even baking and prevents crowding in the oven, which can lead to uneven results.

Reheating: If you prefer a warm treat, gently reheat filled cookies in the microwave for about 10-15 seconds until just warmed through—perfect for a cozy snack!

Dulce de Leche Cinnamon Sandwich Cookies Recipe FAQs
How do I choose the best ingredients for my cookies?
Absolutely! For the best results, use room temperature unsalted butter for optimal creaming with sugar. Select eggs that are fresh, as they contribute to the cookie’s binding and rise. When choosing cinnamon, opt for a ground version for even flavor distribution, and consider a high-quality dulce de leche for a richer, creamier filling.
How should I store my Dulce de Leche Cinnamon Sandwich Cookies?
You can store your cookies in an airtight container at room temperature for up to 1 week. This helps maintain their softness and freshness. If you’re looking to keep them longer, refrigerate them, well-wrapped, for up to 2 weeks. Just be cautious of the odors that can linger in the fridge.
Can I freeze Dulce de Leche Cinnamon Sandwich Cookies?
Absolutely! To freeze your cookies, I recommend freezing them unfilled. Arrange them in a single layer on a baking sheet and freeze until firm, then transfer to a freezer-safe bag or container, layered with parchment paper. They’ll stay fresh for up to 3 months. Thaw them before filling with dulce de leche for that freshly baked taste!
What if my cookie dough is too sticky or too dry?
If your dough is too sticky, simply add a tablespoon of flour at a time until it reaches a manageable consistency. On the other hand, if it’s too dry, a teaspoon of milk can help moisten it. Remember, the dough should be soft but not overly sticky to ensure beautiful cookie shapes!
Are there any dietary considerations I should be aware of with these cookies?
Certainly! These cookies contain gluten and dairy, so they may not be suitable for individuals with gluten intolerance or lactose sensitivity. For dairy-free options, look for vegan butter substitutes and dairy-free dulce de leche. Always check ingredient labels or consult with your family members about allergies before serving!
How can I enhance the flavor of my Dulce de Leche Cinnamon Sandwich Cookies?
To elevate the flavor profile, consider substituting half of the granulated sugar with brown sugar for a richer taste. You could also sprinkle a pinch of sea salt on the filling for a delightful contrast or mix in some chopped nuts for texture. The more the merrier, so feel free to get creative!
