Dulce de Leche Cinnamon Sandwich Cookies Ingredients
For the Cookies
• Unsalted Butter – adds moisture and richness; for a dairy-free version, use margarine.

• Egg – binds the ingredients together; replace with a flax egg for a vegan alternative.
• Vanilla Extract – enhances flavor; almond extract can be a delightful twist.
• All-Purpose Flour – provides structure for the cookies; swap with a 1:1 gluten-free flour blend if needed.
• Baking Soda – acts as a leavening agent; ensure it’s fresh for the best results.
• Salt – balances sweetness and elevates flavors; try sea salt for complexity.
• Sugar and Ground Cinnamon (for rolling) – gives a sweet and spicy coating; adjust the cinnamon to fit your taste.
For the Filling

Step‑by‑Step Instructions for Dulce de Leche Cinnamon Sandwich Cookies
Step 1: Preheat the Oven
Begin your delightful journey by preheating your oven to 350°F (175°C). This step ensures that your baking environment is ready to produce perfectly golden cookies. As the oven heats, gather your baking sheets lined with parchment paper, ensuring everything is set for assembly.
Step 2: Cream Butter and Sugar
In a large mixing bowl, use an electric mixer to beat together the softened unsalted butter and granulated sugar until the mixture is light and fluffy, approximately 4 minutes. The texture should be airy, indicating the sugar has begun to dissolve, giving your Dulce de Leche Cinnamon Sandwich Cookies a tender bite.
Step 3: Add Egg and Vanilla
Add one large egg and a splash of vanilla extract to the creamed mixture. Mix on medium speed for about 1 minute, ensuring everything is fully combined. You’ll notice a smooth consistency forming, helping to create the lovely flavor depth in your cookies.
Step 4: Mix Dry Ingredients
Slowly add the all-purpose flour, baking soda, and salt to the wet mixture, gradually incorporating until a soft dough forms. Take care not to over-mix; just combine until there are no visible flour streaks. The dough should be cohesive and soft, perfect for rolling into cookies.
Step 5: Chill the Dough
Wrap the dough in plastic wrap and refrigerate for 10 to 15 minutes. Chilling makes the dough easier to handle and prevents excessive spreading during baking, ensuring your Dulce de Leche Cinnamon Sandwich Cookies maintain their shape while being irresistibly chewy.
Step 6: Prepare Cinnamon-Sugar
While the dough chills, prepare your cinnamon-sugar mixture by combining granulated sugar with ground cinnamon in a shallow bowl. This mixture will give your cookies a sweet, spiced exterior that complements the creamy filling beautifully. Set it aside for later.
Step 7: Shape Cookies
Remove the chilled dough from the refrigerator and roll it into 16 to 24 balls, about the size of a tablespoon. Coat each ball generously in your prepared cinnamon-sugar mixture, making sure they are well-covered, then place them on the lined baking sheet, leaving space in between to allow for spreading.
Step 8: Bake
Slide the baking sheet into your preheated oven and bake for 9 to 11 minutes. Keep an eye on them; the edges should become golden while the centers remain soft and slightly underbaked. This technique allows for that signature chewy texture in your Dulce de Leche Cinnamon Sandwich Cookies.
Step 9: Make Filling
While the cookies are baking, prepare the filling by melting a tablespoon of butter in a small saucepan. Stir in the dulce de leche until smooth and creamy, about 2 minutes. Remove from heat and let the mixture cool slightly, ensuring it’s spreadable by the time your cookies are ready.
Step 10: Assemble Cookies
Once the cookies have cooled completely, match them into pairs by size. Spread a generous layer of the dulce de leche filling between the flat sides of the cookies, creating delightful sandwiches. Let them rest for about 1 hour, allowing the flavors to meld beautifully for an irresistible treat.

How to Store and Freeze Dulce de Leche Cinnamon Sandwich Cookies
Airtight Container: Keep your cookies in an airtight container at room temperature for up to a week to maintain their chewy texture and flavor.
Freezer: For longer storage, freeze the assembled cookies for up to 3 months. Place them in a single layer on a baking sheet to freeze, then transfer to a freezer bag.
Dough Freezing: Roll the cookie dough into balls, freeze on a baking sheet, then transfer to a bag. Bake directly from frozen, adding a few extra minutes to the baking time.
Reheating: If you enjoy warm cookies, reheating in the microwave for 10-15 seconds will bring back that fresh-baked feel, enhancing the dulce de leche filling!

Easy Dulce de Leche Cinnamon Sandwich Cookies Recipe FAQs
How do I choose the best dulce de leche for filling?

You can bake them straight from the freezer; just add a few extra minutes to the baking time for perfectly freshly baked cookies anytime you crave them.
What should I do if my cookies spread too much while baking?
If your cookies spread too much during baking, it likely means the dough wasn’t chilled enough. Ensure you chill it for at least 30 minutes before baking, as this helps maintain their shape.
