S’mores are delicious, but they’re not exactly a year-round treat—or at least not if you live in a northern climate. When a campfire is out of the question, this Skillet S’mores Cookie gives you everything you love about the original, in the form of a giant cookie.

And if we didn’t have you at s’mores, we definitely had you at “giant cookie,” right?

Mixing this up is no harder than making your standard chocolate chip cookie recipe. In fact, it’s easier since instead of forming individual cookies, you just press the cookie dough into a cast iron skillet!

Kids absolutely love this recipe, and adults will too! It has that nostalgic flavor going for it—who doesn’t have good memories of making s’mores as a kid?—but that combination of graham crackers, gooey marshmallows, and chocolate is just generally irresistible. Especially when it’s on top of a thick, chewy cookie!

How to Make Skillet S’mores Cookie

1. Prepare

Preheat your oven to 350ºF and grease a 12-inch cast iron pan (or another oven-safe skillet) with butter.

2. Make the Batter

Stir together the butter and sugars in a large bowl. Add the eggs and vanilla, stir, then stir in the dry ingredients. Once combined, fold in the chocolate chips.

3. Bake

Spread the batter into the prepared cast iron pan and bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean. 

4. Top

Remove the skillet from the oven and top the cookie with marshmallows, chocolate bar pieces, and graham crackers. Return it to the oven and bake for another 6 to 7 minutes, or until the marshmallows are lightly toasted. 

5. Serve

Let the cookie cool for 10 minutes, then serve your Skillet S’mores Cookie warm. Add a scoop of vanilla ice cream if desired!
