Butter, sugar, egg, vanilla extract, flour, baking soda, salt, cinnamon, and dulce de leche.

There are cookies you make because you need something quick, and then there are cookies you make because you want the kitchen to smell like comfort. These Dulce de Leche Cinnamon Sandwich Cookies are definitely the second kind. They’re soft cinnamon sugar cookies filled with creamy dulce de leche, and honestly, they have that cozy “holiday cookie tray but I’d also eat one on a random Wednesday” feeling. You get the warmth of cinnamon, the softness of a snickerdoodle-style cookie, and that sweet caramel middle that makes every bite feel a little extra. Not complicated-extra. Just oh, this is nice extra.

I’ve always loved cinnamon cookies because they feel simple in the best way. They don’t shout for attention with bright frosting or sprinkles, but the second they start baking, everyone suddenly wanders into the kitchen asking what smells so good. Sound familiar? These Dulce de Leche Cinnamon Sandwich Cookies take that same cozy cinnamon sugar cookie and tuck dulce de leche in the middle, which makes them feel like a bakery treat without needing bakery-level patience. And that’s important, because my patience for fussy cookies is… limited, depending on the day.

The cookie dough is made with basic ingredients: softened butter, sugar, egg, vanilla, flour, baking soda, salt, and cinnamon sugar for rolling. The filling is even easier: dulce de leche warmed with a little butter until it’s smooth and spreadable. That’s it. No piping bag, no complicated decorating, no tiny tweezers, thank goodness. These dulce de leche sandwich cookies look special, but they’re still very much a homemade cookie. A little rustic, a little soft around the edges, and maybe not perfectly matched. That’s okay. Cookie matchmaking is not a perfect science.

What I really like about these cinnamon dulce de leche cookies is how they balance familiar and surprising. Cinnamon sugar cookies already feel nostalgic, like holidays, school bake sales, coffee breaks, and cookie tins lined with wax paper. But the dulce de leche filling gives them a creamy caramel-style center that makes people pause after the first bite. It’s not loud. It’s not over-the-top. It’s just rich, sweet, and warm in that way caramel desserts tend to be.

These cookies are lovely for holiday trays, bake sales, gifting, family gatherings, cookie exchanges, or a cozy weekend baking project. But honestly, I wouldn’t save them only for special occasions. Some cookies feel too fancy for normal life; these don’t. They’re special, yes, but still friendly. Like the cookie version of someone wearing a nice sweater with comfy slippers. A little dressed up, but not trying too hard.

And yes, the dulce de leche might peek out the sides when you press the cookies together. Some cookies might be bigger than others. One might get extra cinnamon sugar because your hand slipped. That’s fine. Actually, I kind of love that. These Dulce de Leche Cinnamon Sandwich Cookies should look homemade, not like they were made by a machine with a ruler and emotional distance.

I have a soft spot for cinnamon sugar cookies because they remind me of the kind of baking that happens when the house feels a little too quiet or the weather makes you want to stay close to the kitchen. I don’t know, maybe it’s the cinnamon. It has a way of making everything feel warmer, even if the sink is full of dishes and someone left a cupboard door open. Again. Cinnamon is forgiving like that.

The first time I made Dulce de Leche Cinnamon Sandwich Cookies, I was really just trying to make a simple cinnamon cookie feel more memorable. I had a can of dulce de leche in the pantry, and it had been there long enough to become one of those ingredients you start feeling guilty about. You know the ones. You bought it with a plan. The plan disappeared. The can remained. So one afternoon, I finally opened it and thought, “Okay, you’re going inside cookies.” Very technical baking process.

I started with a soft cinnamon sugar cookie because it felt like the right match. Snickerdoodle-style cookies have that warm, buttery, slightly crackly cinnamon sugar thing going on, and dulce de leche brings that creamy caramel sweetness. Together, they taste familiar but still a little unexpected. The first batch wasn’t perfectly even—I had a few big cookies, a few smaller ones, and one sandwich that looked like it had been assembled during a small earthquake. Still tasted great. Maybe even better because it had personality.

These dulce de leche cinnamon cookies remind me a bit of holiday baking days, when there’s flour on the counter, cinnamon sugar in places it should not be, and everyone keeps “sampling” cookies before they’re officially ready. But they also remind me of coffee shop treats—the kind you pick up with a latte and tell yourself you’ll save half for later. Which, let’s be honest, rarely happens.

There’s something sweet about assembling sandwich cookies too. You flip the cookies over, spread dulce de leche on one bottom, press another cookie on top, and suddenly it feels like you made something much fancier than you did. I like recipes that give you that tiny proud moment. Nothing dramatic, just a quiet little “hey, these look pretty good.”

And maybe this is just me, but cinnamon and caramel together feel a little nostalgic. Not in a specific “one exact memory” way, but in that general cozy-dessert way. Like kitchen lights in the evening, a plate of cookies on the counter, someone asking if they can have “just one more.” These Dulce de Leche Cinnamon Sandwich Cookies have that feeling. Soft, sweet, warm, and a little messy in the best possible way.

Why you’ll Love these Dulce de Leche Cinnamon Sandwich Cookies?

You’ll love these Dulce de Leche Cinnamon Sandwich Cookies because they take a simple cinnamon sugar cookie and make it feel a little more special without making the process stressful. The cookies are soft and buttery, the cinnamon sugar coating gives them warmth, and the dulce de leche filling adds that creamy caramel-style center. It’s a cozy cookie with a surprise in the middle, and I personally think more cookies should have surprises.

One of the biggest reasons these dulce de leche sandwich cookies work so well is the texture. The cookies bake up soft in the center with lightly golden edges, which is exactly what you want for a sandwich cookie. If the cookies are too crisp, the filling squishes out when you bite them. If they’re too soft, they can fall apart. These land in that happy middle—tender enough to bite, sturdy enough to hold the filling. At least that’s the goal, and it’s a very good goal.

They also taste like something from a bakery, but the ingredient list is wonderfully normal. Butter, sugar, egg, vanilla, flour, baking soda, salt, cinnamon, and dulce de leche. Nothing wild. Nothing that makes you visit three stores and question your life choices. The dulce de leche does most of the heavy lifting in the “wow” department, which is helpful because it comes ready to be delicious straight from the can.

Another reason to love these cinnamon sandwich cookies is that they’re beautiful without needing much decoration. The cinnamon sugar coating gives them a soft golden sparkle, and the dulce de leche peeking from the middle makes them look rich and inviting. You can dress them up with chocolate drizzle or rolled edges, sure, but they don’t need it. Sometimes simple is better. Or at least simple is better when you’ve already washed the mixing bowl.

These cookies are also great for sharing. They work for Christmas cookie trays, Thanksgiving dessert boards, bake sales, baby showers, birthdays, lunchbox treats, or weekend coffee breaks. They feel festive, but not locked into one season. I’d happily make these in December, but I’d also make them in May just because I wanted something cinnamon-y with coffee. No rules.

And the flavor is flexible. You can keep the cookies classic, add a pinch of nutmeg, drizzle chocolate on top, roll the edges in chopped nuts or toasted coconut, or make mini versions for gifting. These Dulce de Leche Cinnamon Sandwich Cookies give you a soft, sweet starting point, and then you can play from there. Ever tried something similar with caramel or cinnamon cookies?

Ingredient Notes

The ingredients for Dulce de Leche Cinnamon Sandwich Cookies are simple, but this is one of those recipes where simple doesn’t mean boring. Each ingredient has a job. The butter gives richness, the sugar adds sweetness and texture, the cinnamon brings warmth, and the dulce de leche makes the cookies feel indulgent. Nothing too fancy, just good cookie basics coming together in a very cozy way.

• Butter: Softened butter is important for the cookie dough because it creams with the sugar and helps create a soft, tender texture. You want it soft enough to mix easily, but not melted. Melted butter can make the dough too loose and may cause the cookies to spread more than you want. For the filling, a small amount of butter is melted and stirred into the dulce de leche, making it smoother and easier to spread. It’s a small step, but it helps the filling behave itself a little better.
• Sugar: Sugar sweetens the dough and helps give the cookies those lightly golden edges. You’ll use 1 cup in the dough and another 1/2 cup for the cinnamon sugar coating. Rolling the dough balls in cinnamon sugar gives these cinnamon dulce de leche cookies their classic snickerdoodle-style look and that cozy sparkle on the outside. It also makes the kitchen smell amazing while they bake, which is a bonus I fully support.
• Egg: The egg helps bind the dough and gives the cookies structure. It also adds moisture, which helps keep the cookies soft. Use one large egg, and mix it in well with the butter and sugar before adding the dry ingredients. This helps the dough come together evenly.
• Vanilla extract: Vanilla adds warmth and rounds out the flavor. It’s not the loudest ingredient here, but it helps the cookie dough taste complete. Cinnamon and dulce de leche both love vanilla, so even those 2 teaspoons matter.
• Flour: All-purpose flour gives the cookies structure. Try to measure it with a light hand. Too much flour can make the cookies dry or heavy, and these Dulce de Leche Cinnamon Sandwich Cookies are best when they stay soft and tender. If you scoop from the bag, don’t pack it down too firmly. Little detail, but it can make a difference.
• Baking soda: Baking soda helps the cookies spread slightly and bake up tender. It also gives them that soft, gently crackled look. Make sure your baking soda is fresh. Old baking soda can make cookies flatter or duller, and honestly, nobody wants a cookie with low energy.
• Salt: Salt balances the sweetness from the sugar and dulce de leche. It might seem minor, but it keeps the cookies from tasting flat. A little salt makes the cinnamon, butter, and caramel-style filling taste more alive. Tiny ingredient, big responsibility.
• Cinnamon: Cinnamon is mixed with sugar to coat the cookie dough balls. It gives these dulce de leche cinnamon sandwich cookies their warm flavor and pretty cinnamon sugar crust. If you really love cinnamon, you can add a small pinch directly into the dough too. I like that sometimes, especially around the holidays.
• Dulce de leche: Dulce de leche is the creamy caramel-style filling in these sandwich cookies. Canned dulce de leche, such as Nestle Dulce de Lechera, works well because it’s thick, sweet, and smooth. When mixed with melted butter, it becomes easier to spread between the cookies. It’s rich, so you don’t need a mountain of it—just enough to make every bite feel special.

How to Make Dulce de Leche Cinnamon Sandwich Cookies?

Making Dulce de Leche Cinnamon Sandwich Cookies is pretty straightforward, but there are a few little moments that matter. Cream the butter and sugar well, chill the dough briefly, don’t overbake the cookies, and let them cool completely before filling. That last one is important. Warm cookies and dulce de leche are delicious, yes, but they can also turn into a slippery caramel situation. Ask me how I know. Actually, maybe don’t.

Step 1: Cream the Butter and Sugar

In a large mixing bowl, cream the softened butter with 1 cup of sugar for about 4 minutes, or until the mixture looks light and fluffy. This step gives the cookies a softer texture. It may feel like a long time if you’re standing there watching the mixer, but it’s worth it. The butter and sugar should look smoother and lighter when they’re ready.

Step 2: Add the Egg and Vanilla

Add the egg and vanilla extract, then mix for about 1 minute. Scrape down the sides of the bowl if needed. You want everything combined before adding the dry ingredients. The egg helps the dough hold together, and the vanilla adds that warm cookie flavor that makes the whole thing smell better before it even bakes.

Step 3: Add the Flour, Baking Soda, and Salt

Stir in the flour, baking soda, and salt. Mix just until the dough comes together. Once the flour goes in, try not to overmix. Too much mixing can make the cookies tougher, and these Dulce de Leche Cinnamon Sandwich Cookies are best when they stay soft. The dough should be soft, not runny.

Step 4: Chill the Dough

Place the dough in the refrigerator for 10 to 15 minutes. This short chill makes the dough easier to roll and helps the cookies spread less while baking. It’s not a long chill, thankfully. Just enough time to clear the counter, make the cinnamon sugar, or stand there pretending you’re not already thinking about the finished cookies.

Step 5: Make the Cinnamon Sugar

In a shallow bowl, combine the remaining 1/2 cup sugar with 2 teaspoons cinnamon. Stir until the cinnamon is evenly mixed through the sugar. This coating is what gives these cinnamon sandwich cookies their warm flavor and classic look.

Step 6: Roll the Dough Balls

Roll the chilled dough into 16 to 24 balls, depending on how large you want the cookies. Fewer balls will make larger sandwich cookies, while more balls will make smaller ones. Try to keep them fairly even so they match up nicely later. But if they’re not perfect, don’t stress. Homemade cookies are allowed to have personality.

Step 7: Coat in Cinnamon Sugar

Drop each dough ball into the cinnamon sugar mixture and roll it until well coated. Make sure all sides are covered. That cinnamon sugar layer adds flavor, texture, and a little sparkle. It’s the part that makes these cookies smell like something you absolutely need to taste “just to check.”

Step 8: Arrange on the Baking Sheet

Place the coated dough balls on a parchment-lined or Silpat-covered baking sheet. Leave enough space between each cookie so they can spread as they bake. If the pan feels crowded, bake in batches. Crowded cookies can bake unevenly, and they deserve better.

Step 9: Bake Until Soft and Lightly Golden

Bake at 350°F for 9 to 11 minutes, or until the edges are lightly golden but the centers still look soft. Don’t overbake them. The cookies will continue to set as they cool. If you want, sprinkle extra cinnamon sugar over the warm cookies right after they come out of the oven. It gives them a little extra flavor and sparkle.

Step 10: Cool the Cookies Completely

Let the cookies cool on the baking sheet for a few minutes, then transfer them to a wire rack. Allow them to cool completely before filling. I know waiting is annoying, but it matters. If the cookies are warm, the dulce de leche filling can soften too much and slide out when you sandwich them.

Step 11: Make the Dulce de Leche Filling

Melt 1 tablespoon butter in a small saucepan. Remove the pan from the heat and immediately stir in the can of dulce de leche until smooth and spreadable. The butter loosens the dulce de leche slightly so it spreads more easily. Don’t overheat it; you just want it smooth, not runny.

Step 12: Assemble the Cookies

Spread the dulce de leche filling on the bottom of one cookie, then top it with another cookie to create a sandwich. Press gently so the filling moves toward the edges without spilling out everywhere. Repeat with the remaining cookies. And there you go: soft, sweet, cinnamon-sugar Dulce de Leche Cinnamon Sandwich Cookies with a creamy caramel center.

Storage Options

These Dulce de Leche Cinnamon Sandwich Cookies store well, but because they have a soft filling, they need a little care. The cookies may soften slightly after being filled, which I actually like because it makes them feel tender and bakery-like. But if you want them neat for a tray or gift box, storage matters.

• Room temperature: Store the assembled cookies in an airtight container at room temperature for up to 2 days, as long as your kitchen is cool. Place parchment paper between layers so the cookies don’t stick together. Keep them away from heat or direct sunlight because the dulce de leche can soften around the edges.
• Refrigerator: For longer storage, place the dulce de leche sandwich cookies in an airtight container and refrigerate for up to 5 days. The refrigerator helps keep the filling firm, especially in warmer kitchens. Let the cookies sit at room temperature for a few minutes before serving so the filling softens slightly and the cookie tastes its best.
• Freezer: You can freeze these cookies for up to 2 months. For the best texture, freeze the cinnamon cookies unfilled, then thaw and fill them before serving. Assembled cookies can also be frozen, but the dulce de leche filling may change texture a bit once thawed. Still tasty, just maybe not as perfect-looking.
• Make-ahead option: The cookie dough can be made ahead and chilled for up to 24 hours before baking. If it becomes too firm, let it sit at room temperature for a few minutes before rolling. You can also bake the cookies ahead and fill them the day you plan to serve. This is especially helpful for holidays when the kitchen schedule gets a little chaotic.
• Storing unfilled cookies: Baked, unfilled cinnamon cookies can be stored in an airtight container at room temperature for up to 3 days. Fill them shortly before serving for the cleanest edges and freshest texture. This is my favorite option if I’m making them for a cookie tray or gift box.
• Preventing sticky layers: If you need to stack assembled Dulce de Leche Cinnamon Sandwich Cookies, place parchment or wax paper between the layers. Dulce de leche can soften and stick, especially near the edges. Parchment keeps the cookies separated and saves you from pulling apart one giant cookie tower.

Variations & Substitutions

These Dulce de Leche Cinnamon Sandwich Cookies are already cozy and rich, but there are plenty of ways to make them your own. You can add more spice, change the filling, make them mini, drizzle them with chocolate, or roll the edges in something crunchy. The recipe is simple enough to play with, which is always nice when you want a cookie that can change moods.

• Add more warm spices: Cinnamon is the star, but a small pinch of nutmeg, cardamom, ginger, or cloves can add more warmth. This is especially good for holiday cookie trays. Just go lightly so the spices don’t overpower the dulce de leche. A little spice feels cozy; too much can start tasting like a candle, and we don’t need that.
• Use caramel instead of dulce de leche: If you don’t have dulce de leche, you can use a thick caramel spread. Avoid thin caramel sauce because it may run out of the cookies and make everything messy. Dulce de leche works best because it’s thick enough to hold its shape inside the sandwich cookies.
• Add chocolate drizzle: Drizzle the assembled cookies with melted dark chocolate, milk chocolate, or white chocolate. Dark chocolate is especially nice because it balances the sweet filling. It also makes these cinnamon dulce de leche cookies look extra special with very little effort.
• Roll the edges: After assembling the cookies, roll the exposed dulce de leche edges in chopped nuts, toasted coconut, mini chocolate chips, or cinnamon sugar. This adds texture and makes the cookies look more finished. It’s a small step, but it gives bakery-window energy.
• Make mini sandwich cookies: Roll smaller dough balls to make bite-sized dulce de leche sandwich cookies. These are great for cookie boxes, parties, dessert boards, or holiday trays. Just watch the baking time because smaller cookies bake faster. Also, mini cookies are dangerous because somehow three still feels like one.
• Use brown sugar: Replace part of the granulated sugar in the dough with light brown sugar for a slightly softer cookie and deeper flavor. Brown sugar pairs beautifully with cinnamon and dulce de leche. The cookies may spread a little differently, but the flavor is worth trying.
• Add citrus zest: A little orange zest in the dough adds brightness and balances the sweetness of the dulce de leche. Orange and cinnamon are a beautiful pair. Lemon zest can work too if you want a lighter, fresher flavor. It’s a tiny twist, but it changes the cookie in a lovely way.
• Add extra cinnamon sugar: Sprinkle extra cinnamon sugar over the cookies as soon as they come out of the oven. The warmth helps it settle onto the tops. This gives the cookies more sparkle and a stronger cinnamon sugar flavor.
• Add cream cheese to the filling: For a tangier filling, mix the dulce de leche with a little softened cream cheese instead of butter. It makes the filling less sweet and a little more balanced. Not the classic version, but honestly, it sounds good, doesn’t it?
• Make a holiday version: Add festive sprinkles to the cinnamon sugar coating or drizzle the finished cookies with white chocolate and sprinkles. These Dulce de Leche Cinnamon Sandwich Cookies already feel cozy, but a little sparkle makes them party-ready.

What to Serve With Dulce de Leche Cinnamon Sandwich Cookies?

These Dulce de Leche Cinnamon Sandwich Cookies are soft, sweet, warmly spiced, and filled with creamy caramel goodness, so they pair best with drinks and sides that balance the richness. You don’t need much with them, but the right pairing can make them feel even more special. Think coffee, milk, tea, fruit, or ice cream. Basically, cookie happiness with a sidekick.

• Hot coffee: Coffee is one of my favorite pairings with these cookies. The slight bitterness balances the sweet dulce de leche filling, and the cinnamon makes the whole thing feel cozy. One cookie with coffee feels like an afternoon break that actually knows what it’s doing.
• Cold milk: Milk and cookies are classic for a reason. Cold milk softens the sweetness and makes these cinnamon sandwich cookies feel nostalgic. It’s a great option for kids, but let’s not pretend adults don’t love it too.
• Hot chocolate: If you want a full cozy dessert moment, serve these cookies with hot chocolate. Cinnamon, caramel, and cocoa work beautifully together. It’s sweet, yes, but sometimes sweet is exactly the point.
• Chai tea: Chai tea is a lovely match because it already has warm spices like cinnamon, cardamom, and cloves. It brings out the spice in the cookies and makes the pairing feel extra comforting. Very curled-up-on-the-couch energy.
• Black tea: A simple black tea helps balance the richness of these dulce de leche cinnamon sandwich cookies. English breakfast or Earl Grey both work well. Earl Grey adds a light citrus note that pairs nicely with cinnamon and caramel.
• Vanilla ice cream: For a plated dessert, serve one sandwich cookie with a scoop of vanilla ice cream. The cold ice cream next to the soft cinnamon cookie and dulce de leche filling is so good. Add a little extra dulce de leche on top if you’re feeling dramatic. Dessert supports drama.
• Fresh berries: Strawberries, raspberries, or blueberries add freshness and a little tartness. They help balance the rich filling and make the dessert plate look pretty. This is a nice pairing for parties or cookie boards.
• Apple slices: Apples and cinnamon just belong together. Serve these cookies with crisp apple slices for a simple snack plate. The fresh crunch helps balance the soft cookie and creamy filling.
• Dessert boards: Add these Dulce de Leche Cinnamon Sandwich Cookies to a dessert board with fruit, chocolate, pretzels, nuts, and other cookies. Their cinnamon sugar coating and caramel center make them stand out without needing extra decoration.
• Espresso: If you like strong coffee, espresso is a perfect pairing. The bold coffee flavor cuts through the sweetness and makes the dulce de leche taste even richer. Tiny cup, big personality.
