Ingredients for S’mores Cookie Skillet

For the Chocolate Chip Cookie Base

• ½ cup (115 g) unsalted butter, melted and slightly cooled
• ½ cup (100 g) packed brown sugar
• ¼ cup (50 g) granulated sugar
• 1 large egg
• 1 teaspoon vanilla extract
• 1¼ cups (160 g) all-purpose flour
• ½ teaspoon baking soda
• ½ teaspoon salt

• 1 chocolate bar (about 1.5 oz / 40 g), chopped

Ingredient Tip: Milk chocolate creates a sweeter, more traditional s’mores flavor, while semi-sweet chocolate balances the sweetness of the marshmallows.

How to Make S’mores Cookie Skillet

Making this homemade skillet cookie is surprisingly simple.

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C).

Lightly grease a 10–12-inch cast iron skillet with butter.

A well-seasoned cast iron skillet helps create golden edges while keeping the center soft.

Step 2: Mix the Butter and Sugars

In a large mixing bowl, combine the melted butter, brown sugar, and granulated sugar.

Whisk until the mixture looks smooth and creamy.

The brown sugar adds moisture and gives the cookie its signature chewy texture.

Step 3: Add Egg and Vanilla

Add the egg and vanilla extract.

Whisk until everything is fully incorporated.

Make sure the melted butter has cooled slightly before adding the egg.

Step 4: Add the Dry Ingredients

Stir in the flour, baking soda, and salt.

Mix gently until a soft cookie dough forms.

Avoid overmixing because it can make the cookie tough rather than tender.

Step 5: Add the Chocolate

Fold in the chocolate chips and chopped chocolate bar.

Distribute the chocolate evenly so every serving contains delicious melted chocolate.

Press the dough into your prepared skillet, spreading it toward the edges.

Step 6: Bake the Cookie Base

Place the skillet in the preheated oven.

Bake for approximately 18–20 minutes, until the edges turn golden brown and the center is just set.

The cookie should remain slightly soft because it will continue cooking from the skillet’s residual heat.

Step 7: Add the Marshmallows

Carefully remove the skillet from the oven.

Arrange marshmallows over the warm cookie, concentrating them toward the center.

You can use large marshmallows for a dramatic toasted appearance or mini marshmallows for more even coverage.

Step 8: Toast the Marshmallows

Switch your oven to broil.

Return the skillet to the oven and broil for approximately 1–2 minutes, watching continuously.

The marshmallows should become lightly golden and toasted.

Be extremely careful because marshmallows can burn within seconds.

Step 9: Finish and Serve

Remove the skillet and sprinkle graham cracker crumbs over the toasted marshmallows.

Allow the dessert to rest for 5–10 minutes.

Serve warm with a large spoon to enjoy the melted chocolate and stretchy marshmallow topping.

Tips for the Best S’mores Skillet Cookie

Don’t overbake the cookie: A slightly soft center creates the best gooey texture.

Use good-quality chocolate: Chocolate bars create larger melted pockets than chocolate chips alone.

Watch the broiler: Marshmallows toast quickly, so never leave them unattended.

Use a cast iron skillet: Cast iron retains heat and produces beautifully golden edges.

Serve warm: The marshmallows and chocolate are at their best while still soft.

Let it rest briefly: A few minutes of cooling makes serving easier without losing that gooey texture.

Delicious Variations

Peanut Butter S’mores: Swirl a few tablespoons of peanut butter into the cookie dough.

Double Chocolate: Add cocoa powder to create a chocolate cookie base.

Caramel S’mores: Drizzle warm caramel sauce over the finished dessert.

Extra Graham Crackers: Add crushed graham crackers to the cookie dough for more traditional campfire flavor.

Ice Cream Skillet: Serve each warm portion with a scoop of vanilla ice cream.

How to Store and Reheat

Although this dessert tastes best fresh, leftovers can be saved.

Room Temperature: Store covered for up to two days in a cool kitchen.

Refrigerator: Keep leftovers in an airtight container for up to four days.

Reheating: Microwave individual portions for approximately 15–20 seconds until warmed through.

The marshmallows may become stickier after reheating, but the dessert will still taste delicious.

Frequently Asked Questions

Can I make this without a cast iron skillet?

Yes! Use a similar-sized oven-safe baking dish. Baking time may vary depending on the dish.

Can I use mini marshmallows?

Absolutely. Mini marshmallows melt and toast quickly, creating a more even topping.

Why is my skillet cookie dry?

Overbaking or adding too much flour can cause dryness. Remove the cookie when the center is just set.

Can I prepare the cookie dough ahead?

Yes. Refrigerate the covered dough for up to 24 hours before baking.

Can I make this dessert for a party?

Definitely! Bake the cookie base shortly before serving, then toast the marshmallows when your guests are ready for dessert.
