Step‑by‑Step Instructions for Dulce de Leche Cinnamon Sandwich Cookies
Step 1: Cream Butter & Sugar
In a mixing bowl, combine 1 cup of softened unsalted butter with 1 cup of granulated sugar. Using an electric mixer on medium speed, cream the mixture until it becomes light and fluffy, which should take about 4 minutes. This process incorporates air, ensuring your Dulce de Leche Cinnamon Sandwich Cookies will have a delightful texture.
Step 2: Add Egg & Vanilla
Next, crack in 1 large egg and pour in 1 teaspoon of pure vanilla extract into the creamed mixture. Blend the ingredients together at medium speed until they are thoroughly combined and smooth, about 1-2 minutes. The moisture from the egg and the fragrant vanilla will create a rich base for your cookie dough.
Step 3: Mix Dry Ingredients
In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and 1/2 teaspoon of salt. Gradually add this dry mixture to the wet ingredients while mixing on low speed. Continue mixing until the dough comes together into a smooth, cohesive texture that holds its shape, which should take about 1-2 minutes.
Step 4: Chill Dough
Once your dough is well-formed, cover the bowl with plastic wrap and place it in the refrigerator. Chill the dough for about 10 to 15 minutes, allowing it to firm up. This step is essential for preventing the cookies from spreading too much during baking, ensuring they maintain their shape.
Step 5: Prepare Cinnamon-Sugar
While the dough chills, prepare the cinnamon-sugar coating. In a small bowl, mix together 1/2 cup of granulated sugar with 2 teaspoons of ground cinnamon until evenly combined. This mixture will add a deliciously sweet crunch to the outside of your Dulce de Leche Cinnamon Sandwich Cookies.
Step 6: Form Cookie Balls
After chilling, preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper. Roll the chilled dough into 16 to 24 evenly-sized balls, about 1 inch in diameter. Roll each ball in the prepared cinnamon-sugar mixture to coat them fully before placing them on the baking sheet, spacing them about 2 inches apart.
Step 7: Bake
Bake the cookies in your preheated oven for 9 to 11 minutes, or until the edges turn golden and the centers remain soft. Keep an eye on them as they bake; they should be set yet still look slightly underbaked. Once ready, remove the baking sheet from the oven and allow the cookies to cool for a few minutes.
Step 8: Cool & Fill
After they have cooled slightly, transfer the cookies to a wire rack to cool completely. In the meantime, mix 1 cup of dulce de leche with 2 tablespoons of softened butter until smooth. Once the cookies are cool, spread a generous amount of the creamy filling on the flat side of one cookie and sandwich it with another, creating delectable Dulce de Leche Cinnamon Sandwich Cookies.
