There’s something magical about the combination of graham crackers, chocolate, and toasted marshmallows that makes s’mores an irresistible treat. But what happens when you add a bright burst of lemon to this classic campfire favorite? Pure bliss! Today, I’m excited to share my recipe for Lemon S’mores Cookies – a zingy, tangy twist on traditional s’mores that will have your taste buds dancing with delight.
These cookies combine the nostalgic flavors of s’mores with refreshing lemon notes, creating a perfect balance of sweetness and tartness. The buttery graham cracker cookie base is infused with fresh lemon zest, topped with gooey marshmallows and rich chocolate, then finished with a drizzle of lemon glaze. It’s like summer sunshine and cozy campfires had a delicious cookie baby!
Why I Created These Cookies
I’ve always been a s’mores enthusiast. Those summer nights around a campfire, roasting marshmallows to golden perfection, then sandwiching them between graham crackers with a piece of melty chocolate – pure heaven! But as much as I love traditional s’mores, I’m also a big fan of citrus desserts, particularly anything lemon.
One day, while preparing for a summer gathering, I wanted to bring something unique that would showcase both flavors I love. That’s when inspiration struck – why not combine the comforting nostalgia of s’mores with the bright, refreshing taste of lemon? After several test batches (and many happy taste-testers), these Lemon S’mores Cookies were born.
The result was even better than I’d hoped. The lemon adds a surprising twist that cuts through the sweetness of the marshmallows and chocolate, creating a perfectly balanced cookie that’s impossible to resist. They’ve become my signature dessert for summer gatherings, though they’re delightful year-round when you need a little sunshine on your plate!
What Makes These Cookies Special
These aren’t just any cookies – they’re a carefully crafted fusion of flavors and textures that create a truly memorable dessert experience:
- Graham Cracker Base: Unlike traditional cookies, these start with a graham cracker-infused dough that immediately evokes the flavor of classic s’mores.
- Lemon Infusion: Fresh lemon zest and juice bring brightness to every element, from the cookie dough to the sweet glaze.
- Texture Contrast: The soft, chewy cookie combined with gooey marshmallows and smooth chocolate creates a perfect textural balance.
- Visual Appeal: With their golden edges, toasted marshmallows, and artful lemon glaze drizzle, these cookies are as beautiful as they are delicious.
- Seasonal Versatility: Perfect for summer gatherings but equally welcome during winter months when you need a reminder of sunshine.

Ingredients You’ll Need
For the cookies:
- 1 cup (2 sticks) unsalted butter, softened
- 3/4 cup granulated sugar
- 1/2 cup light brown sugar, packed
- 2 large eggs, room temperature
- 2 tablespoons fresh lemon juice
- 2 tablespoons lemon zest (from about 2 medium lemons)
- 1 teaspoon vanilla extract
- 2 1/4 cups all-purpose flour
- 1 1/2 cups graham cracker crumbs (about 10 full sheets, finely crushed)
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup mini marshmallows
- 8 oz high-quality chocolate (milk or dark), chopped into chunks
- 4 graham crackers, broken into small pieces for topping
For the lemon glaze:
- 1 cup powdered sugar
- 2-3 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- Pinch of salt
Essential Equipment
Before we dive into the baking process, let’s make sure you have all the necessary tools:
- Stand mixer or hand mixer
- Microplane or zester for lemons
- Measuring cups and spoons
- Large mixing bowls
- Baking sheets
- Parchment paper or silicone baking mats
- Cookie scoop (about 2 tablespoons capacity)
- Cooling racks
- Small bowl for glaze
- Whisk for glaze
- Fork or small spoon for drizzling
Step-by-Step Instructions
Preparing the Cookie Dough
- Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
- Cream the butter and sugars. In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), beat the softened butter, granulated sugar, and brown sugar until light and fluffy, about 3-4 minutes. Don’t rush this step – proper creaming creates the perfect cookie texture!
- Add the eggs and flavorings. Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Then mix in the lemon juice, lemon zest, and vanilla extract. The mixture might look slightly curdled due to the lemon juice – that’s completely normal!
- Combine dry ingredients. In a separate bowl, whisk together the flour, graham cracker crumbs, baking soda, and salt.
- Mix the dough. Gradually add the dry ingredients to the wet ingredients, mixing on low speed just until combined. Be careful not to overmix, as this can result in tough cookies.
- Fold in the chocolate. Using a spatula, gently fold in about 3/4 of the chocolate chunks, saving the rest for topping.
Shaping and Baking
- Scoop the dough. Using a cookie scoop, portion the dough into balls (about 2 tablespoons each) and place them on the prepared baking sheets, leaving about 2 inches between each cookie.
- Add toppings. Press a few pieces of the reserved chocolate chunks onto each cookie dough ball.
- First bake. Bake the cookies for 8 minutes, until the edges are just beginning to set but the centers are still soft.
- Add marshmallows. Remove the cookies from the oven and quickly press 3-4 mini marshmallows and a few graham cracker pieces into the top of each cookie.
- Final bake. Return the cookies to the oven and bake for an additional 3-4 minutes, until the marshmallows are puffy and lightly golden and the cookies are set around the edges but still soft in the center.
- Cool properly. Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.

Preparing the Lemon Glaze
- Mix the glaze ingredients. In a small bowl, whisk together the powdered sugar, 2 tablespoons of lemon juice, lemon zest, and a pinch of salt until smooth. Add more lemon juice as needed to achieve a drizzling consistency.
- Drizzle the cookies. Once the cookies are completely cool, use a fork or small spoon to drizzle the lemon glaze over each cookie.
- Allow the glaze to set. Let the cookies stand for about 15-20 minutes to allow the glaze to set before serving or storing.

Tips for Perfect Lemon S’mores Cookies Every Time
- Zest before juicing: Always zest your lemons before juicing them – it’s much easier!
- Room temperature ingredients: Make sure your butter and eggs are at room temperature for the best texture.
- Don’t overmix: Stop mixing as soon as the dry ingredients are incorporated to avoid tough cookies.
- Use fresh lemons: The oils in fresh lemon zest provide much more flavor than bottled juice or dried zest.
- Watch carefully during the second bake: Marshmallows can go from perfectly golden to burnt very quickly.
- Customize the chocolate: Feel free to use milk, dark, or white chocolate based on your preference – they all work beautifully with lemon.
- Perfect your timing: The key to soft, chewy cookies is taking them out when they seem slightly underdone in the center – they’ll continue cooking on the hot baking sheet.
- Quality matters: Use high-quality chocolate and real graham crackers for the most authentic s’mores flavor.
- Let the glaze set completely: For clean cutting and storing, allow the glaze to harden fully.
- Make them your own: Don’t be afraid to adjust the lemon intensity to suit your taste – add more zest for a stronger lemon flavor or reduce for a milder note.

Frequently Asked Questions
Q: Can I make these cookies ahead of time for a party?
A: Absolutely! You can make the dough up to 2 days in advance and store it in the refrigerator. You can also bake the cookies 1-2 days ahead and store them in an airtight container. I’d recommend adding the lemon glaze the day of serving for the freshest appearance.
Q: How do I know when the cookies are done baking?
A: The cookies should be golden around the edges but still slightly soft in the center. The marshmallows should be puffy and just starting to turn golden. Remember that the cookies will continue to firm up as they cool.
Q: Can I use lemon extract instead of fresh lemon?
A: While fresh lemon provides the best flavor, you can substitute 1/2 teaspoon lemon extract for the zest if necessary. I still recommend using some fresh lemon juice in the glaze for brightness.
Q: My marshmallows melted too much. What did I do wrong?
A: This usually happens if the marshmallows are added too early or if the oven temperature is too high. Make sure to add them after the initial 8
