Crafted with incredibly soft, chewy graham cracker chocolate chip cookies and a luscious, fluffy marshmallow filling, these treats capture all the beloved flavors of s’mores without the need for a bonfire or sticky fingers. Even if you’re not typically a s’mores enthusiast, the exquisite combination of textures and tastes in these homemade cookie sandwiches is guaranteed to win you over. They’re perfect for parties, dessert cravings, or simply as a comforting snack any time of year.

What Exactly Are S’mores Cookie Sandwiches?
Imagine your favorite s’more, but elevated and transformed into a sophisticated, yet utterly comforting, cookie sandwich. Our S’mores Cookie Sandwiches start with a wonderfully unique chocolate chip cookie base. We infuse the dough with finely crushed graham cracker crumbs, giving each bite that signature, subtly sweet, and slightly crunchy graham cracker flavor. These cookies are then baked to a golden-brown perfection, ensuring they remain soft and chewy. The magic happens when two of these delightful cookies are brought together with a generously thick, homemade marshmallow filling – a smooth, creamy concoction that perfectly mimics the gooey sweetness of toasted marshmallows, but without the mess or the risk of burning. It’s truly a s’mores experience in a handheld, easy-to-eat format that everyone will adore.
Unlike traditional s’mores that can be messy and require a specific setting, these cookie sandwiches offer all the nostalgic flavors in a convenient package. There’s no worrying about over-toasting marshmallows, or the lingering scent of campfire smoke. Just pure, unadulterated s’mores bliss, ready to enjoy. They combine the best elements: rich chocolate, crunchy graham cracker undertones, and a sweet, pillowy marshmallow center, all wrapped up in a tender cookie. They’re quickly becoming a new household favorite for their irresistible charm and ease of preparation.

Key Ingredients for S’mores Cookie Sandwiches
Crafting these delectable cookie sandwiches requires a handful of common baking ingredients, plus a few special ones to give them their distinct s’mores flavor. Here’s a breakdown of what you’ll need and why each component is important:
- 3/4 cup butter – softened to room temperature: The foundation of any good cookie. Softened butter creams beautifully with sugar, creating a light, airy base for your cookies. Ensure it’s not melted, as this changes the cookie’s texture and spread.
- 1/2 cup sugar & 1/2 cup packed brown sugar: The combination of granulated and brown sugar is essential. Granulated sugar provides crispness, while brown sugar adds moisture, chewiness, and a lovely caramel note, contributing to the cookie’s soft texture.
- 1 egg: Acts as a binder, providing structure and richness to the cookie dough.
- 2 Tbsp milk: Adds a touch of moisture, helping to keep the cookies tender and slightly chewy.
- 1 tsp vanilla extract: A flavor enhancer that brings warmth and depth to the overall cookie taste. Don’t skip this!
- 1 1/4 cups flour: All-purpose flour provides the primary structure for the cookies. Measure it correctly by spooning it into a measuring cup and leveling it off.
- 1 1/4 cups graham cracker crumbs (about 20 graham cracker squares): This is the star ingredient that gives these cookies their unique s’mores identity. The crumbs are incorporated directly into the dough, providing a subtle, sweet, and slightly nutty flavor, mimicking the classic graham cracker experience.
- 1/2 tsp baking soda: A leavening agent that helps the cookies rise and spread, contributing to their soft and airy texture.
- 1/4 tsp salt: Balances the sweetness and enhances all the other flavors in the cookies.
- 2 cups semi-sweet (or milk chocolate) chips: Essential for any chocolate chip cookie. Semi-sweet offers a classic balance, while milk chocolate chips will provide a sweeter, creamier profile. Feel free to use your preferred type, or even a mix!
For the Marshmallow Filling:
- 2 cups powdered sugar: Provides the bulk and sweetness for the fluffy filling, dissolving easily for a smooth texture.
- 7 oz jar marshmallow creme: This is the secret to a perfectly smooth, stable, and deliciously gooey marshmallow layer without the fuss of making meringue-based fluff from scratch. It holds its shape beautifully between the cookies.

How to Make S’mores Sandwich Cookies: A Step-by-Step Guide
Making these S’mores Cookie Sandwiches is a fun and rewarding baking project. Follow these detailed steps to ensure perfectly baked cookies and a luscious filling every time:
- Prepare Your Oven: Begin by preheating your oven to 375°F (190°C). This ensures a consistent baking temperature from the moment your cookies enter the oven, which is crucial for even cooking. Line your baking sheets with parchment paper or silicone baking mats for easy cleanup and to prevent sticking.
- Cream Wet Ingredients: In a large mixing bowl, combine the softened butter, granulated sugar, and packed brown sugar. Using an electric mixer, cream these together for 2-3 minutes until the mixture is light, fluffy, and pale in color. This process incorporates air, contributing to the cookies’ final texture. Next, beat in the egg, vanilla extract, and milk for another 2-3 minutes, ensuring everything is thoroughly combined and smooth.
- Combine Dry Ingredients: In a separate medium-sized bowl, whisk together the flour, graham cracker crumbs, baking soda, and salt. Whisking ensures these dry ingredients are evenly distributed before adding them to the wet mixture.
- Mix Dough: Gradually add the dry ingredient mixture to the wet butter and sugar mixture. Mix on low speed, or by hand, just until everything is well combined and no streaks of flour remain. Be careful not to overmix, as this can lead to tough cookies. Finally, fold in the chocolate chips until they are evenly dispersed throughout the dough.
- Scoop and Bake: Using a cookie scoop (approximately 1 tablespoon size), drop rounded scoops of dough onto your prepared cookie sheets, leaving about 2 inches between each cookie to allow for spreading. Bake for 8-10 minutes, or until the edges are lightly golden brown and the centers still look slightly soft. Remember, cookies continue to bake for a few minutes after they are removed from the oven.
- Cool Cookies: Once baked, remove the cookie sheets from the oven and let the cookies cool on the sheets for 3-5 minutes. This allows them to set up without breaking. Then, carefully transfer the cookies to a wire rack to cool completely. It’s vital that the cookies are completely cool before you add the marshmallow filling, otherwise, the filling will melt.
- Prepare Marshmallow Filling: While the cookies are cooling, prepare your filling. In a medium bowl, combine the powdered sugar and the jar of marshmallow creme. Mix with an electric mixer until smooth and well incorporated. The consistency should be thick and spreadable.
- Assemble Cookie Sandwiches: Once the cookies are entirely cool, divide the marshmallow filling into 12 equal portions. Take one portion, roll it into a ball, and gently place it between two cookies. Carefully press the cookies together to flatten the filling evenly to the edges, creating a perfect sandwich. Repeat with the remaining cookies and filling.
- Storage: Store your completed S’mores Cookie Sandwiches at room temperature in an airtight container for up to several days. This helps maintain their softness and prevents the filling from drying out.

Tips for Making the Perfect Graham Cracker Chocolate Chip Cookies
Achieving perfect cookies every time is simpler than you think with a few key techniques. These tips are especially helpful for the graham cracker chocolate chip cookies in this s’mores sandwich recipe:
- Ensure Butter is Properly Softened: This is a critical step often overlooked! Your butter should be at room temperature – soft enough to make a slight indentation with your finger, but not melted or greasy. If butter is too cold, it won’t cream properly, leading to dense cookies. If it’s melted, your cookies will spread too much and become flat. To soften quickly, microwave it in 5-second bursts, carefully checking after each interval. A defrost setting on your microwave can also work wonders, as it softens more evenly without melting.
- Mix Dry Ingredients Separately: Before combining, always mix your flour, graham cracker crumbs, baking soda, and salt in a separate bowl. This ensures that the leavening agent and salt are evenly distributed throughout the dry mixture, preventing pockets of unmixed ingredients and ensuring a uniform rise and flavor in every cookie.
- Cream Butter and Sugars Thoroughly: Don’t rush this step! Creaming the butter and sugars together for 2-3 minutes at medium speed is vital. This process incorporates air into the mixture, which creates a lighter, fluffier cookie with a better texture. It also dissolves the sugar granules, contributing to a smoother dough.
- Preheat Your Oven Fully: Always preheat your oven for at least 15-20 minutes before baking, even after it signals it’s reached temperature. A fully preheated oven ensures a consistent heat from the start, which helps the cookies rise properly and bake evenly, preventing them from spreading too much or baking inconsistently.
- Use a Cookie Scoop for Uniformity: For perfectly shaped, consistently sized cookies that bake evenly, a cookie scoop is your best friend. It takes the guesswork out of portioning and helps create beautiful, uniform cookie sandwiches.
- Invest in Parchment Paper or a Silicone Baking Mat: These baking aids are game-changers! They prevent cookies from sticking to the pan, ensuring easy removal and perfectly shaped bases. They also promote more even browning, especially on the bottom, compared to baking directly on a metal sheet.
- Avoid Overbaking: This is arguably the most important tip for soft, chewy cookies. When you remove your cookies from the oven, they should look slightly underbaked in the center, with just a hint of golden-brown around the edges. Cookies continue to bake on the hot sheet for a few minutes after removal, so taking them out slightly early ensures they don’t become hard or crumbly. Trust the process!

Why Do My Cookies Burn on the Bottom But Aren’t Done in the Middle?
This is a common baking conundrum, and it’s incredibly frustrating when your delicious cookies end up with burnt bottoms and raw centers. The culprit is usually your baking equipment or technique:
- Dark-Colored Baking Sheets: Dark baking sheets absorb and conduct heat more intensely than lighter-colored ones. This can cause the bottoms of your cookies to brown (and potentially burn) much faster than the tops or centers can cook through. If you frequently experience this issue, consider switching to light-colored, reflective aluminum baking sheets.
- Excessive Cooking Spray: While cooking spray is convenient, using too much can create a greasy layer that heats up rapidly and can burn the bottom of your cookies. If you’re using non-stick pans, you often don’t need spray at all. For regular pans, use a very light coating or, better yet, line them.
- No Parchment Paper or Silicone Mats: As mentioned above, parchment paper or silicone baking mats act as a buffer between the hot metal and your cookie dough. They distribute heat more evenly and prevent direct contact with the hottest surface of the pan, significantly reducing the risk of burnt bottoms. I am a huge advocate for silicone baking mats; they make cleanup a breeze and cookies slide off effortlessly.
- Oven Hot Spots: Ovens often have inconsistent heating, with some areas being hotter than others. If your cookies are consistently burning in the same spot on the baking sheet, try rotating the sheet halfway through the baking time. An oven thermometer can also help you gauge the true temperature inside your oven, as built-in thermostats can sometimes be inaccurate.
- Dough Thickness: If your cookie dough balls are too thick or inconsistent in size, the outsides will cook faster than the insides. Ensure uniform scooping as suggested earlier.
By addressing these factors, you can significantly improve your cookie baking results and say goodbye to burnt bottoms!
