Key Ingredient Insights for Your Perfect Skillet Cookie

All the ingredients neatly laid out for a s'mores chocolate chip cookie skillet recipe: butter, sugars, eggs, vanilla, flour, leavening agents, cornstarch, marshmallows, chocolate chips, and graham crackers.

Understanding the role of each ingredient can help you achieve the best possible results and even inspire creative substitutions for your **s’mores chocolate chip skillet cookie**. Here’s a closer look at what makes this recipe shine and how to optimize each component:

Marshmallows: We’ve opted for **mini marshmallows** in this **chocolate chip marshmallow cookie** because they melt into beautifully gooey pockets throughout the cookie, creating that signature s’mores texture. However, if you only have regular-sized marshmallows on hand, feel free to cut them into smaller pieces using kitchen shears. You could even use larger ones for a bigger marshmallow pull – just ensure they are distributed evenly. Remember our pro tip: reserving some for the final minutes of baking ensures a perfectly golden, slightly toasted top layer without burning them.

Butter: For this recipe, I highly recommend using **unsalted European-style butter**. This type of butter, typically found with a higher butterfat content (around 82% compared to standard American butter’s 80%), contributes significantly to a richer, more tender, and wonderfully creamy cookie texture. The higher fat content results in a more flavorful and moist crumb. If European butter isn’t available, high-quality unsalted butter will still work beautifully; just ensure it’s melted and then allowed to cool slightly before incorporating it into your wet ingredients.

Chocolate Chips: The choice of chocolate can greatly influence the overall flavor profile of your **gooey skillet cookie**. You can use classic milk chocolate chips for a sweeter, more traditional s’mores flavor, or opt for dark chocolate chips for a richer, more intense chocolate experience that pairs wonderfully with the sweet marshmallows. A blend of both is also a fantastic option! For those dreamy, expansive chocolate puddles that everyone loves, I highly suggest using **chocolate wafers or roughly chopped chocolate bars** (milk, semi-sweet, or dark) instead of standard chips. Chips are formulated to hold their shape during baking, while chopped chocolate melts more readily and pools beautifully, creating a more decadent texture.

Cornstarch: This humble ingredient is a secret weapon in many cookie recipes, and it plays a vital role here. Adding **cornstarch** to our dough helps to create an incredibly softer, more tender crumb in the **skillet cookie**. It works by inhibiting gluten development in the flour, resulting in a less chewy and more melt-in-your-mouth texture. Don’t skip it for that ultimate soft and delicate center!

Flour: Our recipe has been developed and thoroughly tested using standard **all-purpose flour**. It’s absolutely crucial to measure your flour correctly to avoid a dry or dense cookie, which can result from too much flour. While I haven’t specifically tested this recipe with gluten-free flour blends, if you’re experimenting with a gluten-free diet, look for a good quality 1:1 gluten-free baking blend that contains xanthan gum for the best chance of success. Always ensure your flour is fresh for optimal results in all your baking endeavors.

Graham Crackers: The classic **graham cracker** adds that quintessential s’mores flavor and a delightful, subtle crunch that complements the soft cookie and gooey marshmallows. If you don’t have graham crackers, **digestive biscuits** are an excellent substitute, offering a similar texture and mild sweetness. Alternatively, you can omit them entirely for a fantastic chocolate chip marshmallow skillet cookie, or try crushed shortbread cookies for a slightly different, buttery twist on the classic. Feel free to adjust the amount to your liking for more or less crunch.

Easy Step-by-Step Guide to Your Homemade S’mores Skillet Cookie

Creating this incredible **s’mores chocolate chip skillet cookie** is a breeze, even for beginners. Follow these simple, clear instructions for a perfect, gooey treat every time:

Steps 1 and 2 in the chocolate chip marshmallow cookie skillet baking process, showing wet ingredients being mixed in a bowl.

Step One: Prepare the Wet Ingredients. Begin by preheating your oven to 350°F (175°C). While the oven heats, lightly butter a 9-inch cast iron skillet, ensuring the bottom and sides are well-greased to prevent sticking. In a large mixing bowl, combine the cooled melted butter with both the light brown sugar and granulated sugar. Whisk these ingredients together thoroughly until the mixture is completely smooth and well-combined, taking on the appearance of a thick, glossy, caramel-like paste. This step is crucial for an even distribution of sweetness and contributes significantly to the cookie’s signature chewiness.

Step Two: Incorporate Eggs and Vanilla. To the butter and sugar mixture, add your two large eggs and the additional egg yolk, along with the vanilla extract. Whisk vigorously for about 1-2 minutes until the mixture is entirely smooth, appears lighter in color, and looks slightly fluffy. The extra egg yolk contributes to the cookie’s overall richness and tenderness, while the vanilla extract enhances all the other delicious flavors, bringing depth to your **homemade skillet cookie**.

Steps 3 and 4 in the chocolate chip marshmallow cookie skillet baking process, showing dry ingredients being mixed and then folded into wet ingredients.

Step Three: Combine Dry Ingredients. In a separate large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, kosher salt, and cornstarch. Take your time with this step to ensure these dry ingredients are thoroughly combined and evenly distributed. This prevents any pockets of unmixed leavening agents or salt in your finished cookie, which is crucial for an evenly baked and consistently flavored **skillet cookie**.

Step Four: Gently Fold Wet into Dry. Gradually add the dry ingredient mixture into the wet ingredients. Using a rubber spatula, gently fold everything together until just combined. It’s vital to mix only until no streaks of flour remain; avoid the temptation to overmix the dough, as this can develop the gluten too much, leading to a tough, dense cookie. A light hand here will ensure a wonderfully tender and soft texture for your **chocolate chip marshmallow cookie**.

Steps 5 and 6 in the chocolate chip marshmallow cookie skillet baking process, showing the mix-ins folded into dough and the dough in the cast iron skillet.

Step Five: Introduce the S’mores Goodness. Now for the most exciting part! Pour in the crushed graham crackers, chocolate chips, and mini marshmallows into the cookie dough. Gently fold these delicious additions throughout the dough using your rubber spatula until they are evenly distributed. Be careful not to crush the marshmallows too much. *Pro Tip:* I highly recommend reserving a small handful of marshmallows, chocolate chips, and graham cracker crumbs to sprinkle on top during the final moments of baking. This ensures a beautifully appealing finish with perfectly melted and slightly toasted toppings, enhancing both the look and taste of your **gooey s’mores dessert**.

Step Six: Bake to Golden Perfection. Transfer the prepared cookie dough into your greased 9-inch cast iron skillet, spreading it evenly across the bottom with your spatula. Bake in your preheated oven at 350°F (175°C) for approximately 45-55 minutes. For that picture-perfect, toasted marshmallow and chocolate top, carefully remove the skillet from the oven during the *last five minutes* of baking. Sprinkle over your reserved marshmallows, chocolate chips, and graham cracker crumbs, then return the skillet to the oven. Continue baking for the remaining 5 minutes, or until the edges of the **s’mores skillet cookie** are deeply golden brown and set, while the center remains delightfully gooey and soft. Allow the cookie to rest in the skillet for at least 15 minutes after removing it from the oven before diving in; this crucial cooling time helps it set further and prevents it from falling apart when scooped. Serve warm with ice cream for the ultimate treat!

Expert Tips & Tricks for a Flawless S’mores Skillet Cookie

Achieving bakery-quality results with your **homemade skillet cookie** is easy and straightforward when you keep these valuable tips in mind. They will help ensure your s’mores dessert is perfect every time:

  • Embrace the Weighing Scale for Precision: For the most accurate and consistent baking results, I cannot stress enough the importance of using a **digital kitchen scale** and measuring your ingredients by weight, especially flour. This method eliminates the variability that often comes with volumetric cup measurements, ensuring your dough has the perfect consistency every time. Most of my recipes, including this one, are developed and tested with metric measurements in mind, which offer superior precision.
  • Master the ‘Fluff and Sprinkle’ Method to Measure Your Flour: If a kitchen scale isn’t an option for you, proper volumetric flour measurement is absolutely crucial to avoid common baking pitfalls. Instead of scooping flour directly from the bag, which can compact it and lead to using too much flour, use the ‘fluff and sprinkle’ method. First, fluff your flour with a spoon directly in its container, then gently spoon it into your measuring cup until it overflows, and finally, level it off with the back of a knife. Too much flour can result in a dry, dense, or crumbly **skillet cookie**, so taking care with this step will make a significant difference. Find more details on this technique here.
  • Room Temperature Ingredients are Key: This is a golden rule in baking for a reason! Ensure all your perishable ingredients, most importantly the butter and eggs, are at **room temperature** before you begin mixing. Room temperature ingredients emulsify much better, meaning they combine more smoothly and uniformly. This creates a more stable dough structure, leading to a better overall rise, a more tender crumb, and a more even bake for your **chocolate chip marshmallow cookie**. Plan ahead by taking them out of the fridge at least 30 minutes to an hour before you start.
  • Adjust Baking Time for Your Preferred Gooeyness: The baking time provided (45-55 minutes) is specifically designed to give you an incredibly **gooey s’mores skillet cookie** center, complemented by slightly crisper, golden-brown edges. If you prefer a more well-baked, firmer, and less gooey cookie, you can certainly extend the baking time. To prevent the top from over-browning or the marshmallows from burning during this extended period, simply loosely tent the skillet with aluminum foil during the last 10-15 minutes of baking. A toothpick inserted into the center should come out with just a few moist crumbs for a perfect doneness.
  • Strategically Add Extra Marshmallows for the Best Look: For that signature, beautifully toasted marshmallow top that’s soft and gooey, resist the urge to add all the marshmallows at the very beginning of the baking process. **”Naked” marshmallows** baked for the entire duration can quickly burn and turn into a hard, crunchy mess. Instead, follow the instructions to add a small reserved handful of marshmallows, chocolate chips, and graham cracker crumbs during the *final 5 minutes of baking*. This allows them just enough time to melt, toast lightly, and create that irresistible, gooey s’mores effect without scorching, ensuring a gorgeous and delicious presentation.

Common Questions About This S’mores Skillet Cookie

Got more questions about making and enjoying your **s’mores chocolate chip skillet cookie**? Here are answers to some frequently asked questions:

How do you store a skillet cookie?

This **gooey s’mores dessert** is truly at its peak when enjoyed warm, fresh out of the oven, preferably with a scoop of ice cream. However, if you happen to have any leftovers (a rare occurrence for such a delicious treat!), allow the cookie to cool completely in the pan. Once cooled, cover the skillet tightly with aluminum foil or transfer individual slices to an airtight container. Store it in the refrigerator for up to 3 days. To reheat, you can warm individual slices in the microwave for 15-30 seconds, or place the foil-covered skillet back in a low oven (around 300°F/150°C) for about 10-15 minutes until warmed through and gooey again.

What substitutions can I make to customize my cookie skillet?

This recipe is wonderfully versatile and invites customization! Feel free to get creative with your add-ins. Instead of traditional chocolate chips, you could **swap them out for peanut butter chips, butterscotch chips, white chocolate chunks, or even a mix of different chocolates**. If you only have regular-sized marshmallows, simply cut them into smaller pieces using kitchen shears before adding them to the dough. And if graham crackers aren’t your favorite or aren’t readily available, you can easily **omit them entirely** to create a delicious chocolate chip marshmallow skillet cookie, or experiment with other crushed biscuits like shortbread cookies or digestive biscuits for a different flavor profile and crunch.

Can I use something other than a cast iron pan?

While a **cast iron skillet** is highly recommended for this recipe – it provides exceptional heat retention and even cooking, resulting in those coveted crispy edges and a perfectly gooey center – you can certainly use other oven-safe pans. A ceramic baking dish, a pie plate, or even a deep round cake pan made of metal or glass can work as alternatives. Just be aware that the baking time might vary slightly depending on the material and thickness of your pan, and you might not achieve the exact same level of crispy exterior as you would with traditional cast iron. Always ensure your chosen pan is oven-safe for the specified temperature.

Can I prepare the cookie dough ahead of time?

Yes, you absolutely can! To make your baking day even easier, you can prepare the cookie dough (without adding the marshmallows yet, as they might dissolve or get sticky over time) up to 24-48 hours in advance. Simply mix the dough as instructed, then cover the bowl tightly with plastic wrap and refrigerate. When you’re ready to bake your **homemade skillet cookie**, let the dough come closer to room temperature for about 30 minutes to make it easier to work with. Then, fold in the marshmallows, chocolate chips, and graham crackers, transfer to your greased skillet, and proceed with baking as directed. You might need to add a few extra minutes to the baking time if the dough is still quite cold from the fridge.

Equipment

  • 1 9-inch cast iron skillet
  • 2 Large mixing bowls
  • Whisk
  • Rubber spatula

Ingredients

 

 

  • 1 cup unsalted butter melted and cooled
  • 1 ½ cups light brown sugar
  • ½ cup granulated sugar
  • 2 large eggs at room temperature
  • 1 large egg yolk at room temperature
  • 2 teaspoons vanilla extract
  • 2 ¾ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • 1 teaspoon kosher salt
  • 1 tablespoon cornstarch
  • 2 cups mini marshmallows (divided, for mixing and topping)
  • 1 ½ cups chocolate chips (divided, milk or dark recommended)
  • 2 graham crackers crushed (or digestive biscuits)

Instructions

 

  • Preheat your oven to 350°F (175°C). Lightly butter a 9-inch cast iron skillet, ensuring the bottom and sides are well-greased.
  • In a large bowl, whisk together the cooled melted butter with the light brown sugar and granulated sugar until smooth and well-combined. Add the two eggs, egg yolk, and vanilla extract, then whisk again until the mixture is smooth, lighter in color, and slightly fluffy.
  • In another large bowl, whisk together the all-purpose flour, baking powder, baking soda, kosher salt, and cornstarch until thoroughly combined.
  • Gradually pour the dry ingredients into the wet ingredients. Using a rubber spatula, gently fold everything together until just combined and no streaks of flour remain. Fold in 1.5 cups of the mini marshmallows, 1 cup of the chocolate chips, and 1.5 of the crushed graham crackers until evenly distributed. Reserve the remaining marshmallows, chocolate chips, and graham cracker crumbs for topping.
  • Pour the cookie dough into the greased pan, spreading it evenly. Bake for 45-50 minutes. Carefully remove the skillet from the oven during the last 5 minutes of baking. Sprinkle over the reserved marshmallows, chocolate chips, and graham cracker crumbs. Return the skillet to the oven and bake for another 5 minutes, or until the edges are deep golden brown and the center is still gooey. If you prefer a more baked-through cookie, continue baking for another 10-15 minutes, tented loosely with foil if needed, until a toothpick inserted into the center comes out with just a few moist crumbs. Let the cookie set for at least 15 minutes before serving.

Notes

Measurement Note: My recipes are developed and tested using standard US cups and metric grams. For the most accurate and consistent results, I highly recommend using a digital kitchen scale and measuring your ingredients by weight the metric way.

Room Temperature: Always ensure that all your perishable ingredients, especially butter and eggs, are at room temperature before you begin baking. This helps them combine smoothly and ensures a better texture for your cookie.

Butter Type: For an exceptionally rich and creamy cookie, I prefer to use European-style butter, such as Kerrygold, in my recipes. Its higher butterfat content makes a noticeable difference in the final baked good.

Salt Conversion: If you don’t have kosher salt on hand, you can substitute it with fine table salt. Remember to halve the amount of salt called for in the recipe: 1 teaspoon of kosher salt is equivalent to ½ teaspoon of fine salt.

Storage: To keep any leftovers fresh, allow the skillet cookie to cool completely, then cover the pan tightly with plastic wrap or aluminum foil. Store it in the fridge for up to 3 days. Reheat gently in the microwave or a low oven for best results.
