Why Make This Chewy S’mores Cookies Gooey Marshmallow Bakery

You should make these cookies because they offer a perfect texture contrast that standard chocolate chip cookies lack. The graham cracker crumbs mixed into the flour create a unique, slightly sandy crunch that balances the sweetness. The marshmallows melt into sticky ribbons of sugar, while the chocolate chunks provide a rich, smooth finish. It is a one-bowl wonder that requires no chilling time, meaning you can satisfy your s’mores craving in less than half an hour. Plus, they look stunning with those golden-brown toasted marshmallow tops.

Ingredients

• 1/2 cup unsalted butter, softened
• 1/2 cup light brown sugar, packed
• 1/4 cup granulated sugar
• 1 large egg, room temperature
• 1 teaspoon vanilla extract
• 1 1/4 cups all-purpose flour
• 1/2 cup graham cracker crumbs (about 4-5 full sheets)
• 1/2 teaspoon baking soda
• 1/4 teaspoon salt
• 1 cup semi-sweet chocolate chips or chunks
• 1 cup mini marshmallows
• 1/2 graham cracker sheet, broken into small pieces (for topping)

Directions

Step 1: Preparation

Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats. This step is crucial because the marshmallows will get sticky, and the parchment paper ensures they don’t glue themselves to your pan.

Step 2: Cream the Butter and Sugars

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together using a hand mixer or stand mixer. Cream them for about 2 minutes until the mixture looks light and fluffy. Add the egg and vanilla extract, then beat again until fully combined and smooth.

Step 3: Mix the Dry Ingredients

In a separate small bowl, whisk together the all-purpose flour, graham cracker crumbs, baking soda, and salt. Slowly add the dry ingredients to the wet ingredients. Mix on low speed just until the flour streaks disappear. Do not overmix the dough, or the cookies will become tough.

Step 4: Fold in the S’mores Components

Use a spatula to fold in the chocolate chips and half of the mini marshmallows. Stir gently so you don’t crush the marshmallows. The dough should be thick and slightly tacky to the touch.

Step 5: Scoop and Bake

Scoop rounded tablespoons of dough (about 2 tablespoons per cookie) onto the prepared baking sheets. Space them 2 inches apart. Press a few extra mini marshmallows and small graham cracker pieces into the top of each dough ball. Bake for 9 to 11 minutes. The edges should be golden brown, but the centers should still look slightly soft.

Step 6: Cool and Set

Remove the cookies from the oven. If any marshmallows leaked out and look messy, use a circular glass or cookie cutter to “scoot” the edges back into a perfect circle while they are still hot. Let the cookies rest on the pan for at least 5 minutes to firm up before moving them to a wire rack.

Expert Tips for Perfect Chewy S’mores Cookies Gooey Marshmallow Bakery

For the best results, hide the marshmallows! When rolling the dough balls, try to tuck the marshmallows inside the dough rather than leaving them on the bottom. Marshmallows on the bottom of the cookie will melt and burn against the pan. Also, use a high-quality chocolate bar chopped into chunks instead of chips for those professional-looking pools of melted chocolate. If you want an even deeper flavor, brown your butter before starting the recipe to add a nutty, toasted aroma to the dough.

Delicious Variations

• Dark Chocolate Sea Salt: Use 70% dark chocolate chunks and sprinkle a pinch of flaky sea salt on top after baking.
• Peanut Butter S’mores: Add 1/4 cup of creamy peanut butter to the butter and sugar mixture for a salty-sweet twist.
• Stuffed S’mores: Place a large marshmallow inside the center of the dough ball for a massive “lava” effect when you bite into it.
• Double Graham: Swap the all-purpose flour for a 50/50 mix of whole wheat flour and white flour to enhance the earthy graham cracker taste.

Frequently Asked Questions

Can I make these cookies ahead of time?

Yes, you can prepare the dough and keep it in the refrigerator for up to 3 days. However, wait to add the marshmallows until you are ready to bake, as they can draw moisture from the dough and become soggy over time.

How do I prevent the marshmallows from disappearing?

Marshmallows tend to melt away in the high heat of the oven. To keep them visible and gooey, add a few fresh mini marshmallows to the tops of the cookies halfway through the baking process or immediately after they come out of the oven.

Can I use large marshmallows instead of mini ones?

You can use large marshmallows, but you should cut them into quarters using kitchen shears. Large marshmallows are too big for standard-sized cookies and will likely cause the cookie to lose its shape during baking.

Why did my cookies spread too much?

If your cookies are too flat, your butter might have been too warm (melted instead of softened). Alternatively, you may have over-creamed the butter and sugar. Try chilling the dough balls for 15 minutes before baking to help them hold their shape.

What is the best way to store these?

Store these cookies in an airtight container at room temperature for up to 4 days. If the marshmallows get a bit stiff, pop a cookie in the microwave for 5-10 seconds to restore that “fresh from the oven” gooey texture.
