S’mores for life!

Am I right or am I right?

I have never met anyone who doesn’t like a s’more…and if you happen to be the lone human on the planet to think s’mores are “not your favorite”, please shutty. Not interested in your negativity.

Let’s stay in touch, though.

For the rest of the same-minded people on Earth, let’s talk about this S’mores Skillet Cookie.

Because, friends…it’s the besty best thing ever.

Also, making it absolutely over the top awesome are the GIANT Roaster Marshmallows from Campfire. In case you haven’t heard of them..they are the hugest marshmallows ever, perfect for roasting, eating or putting on top of a skillet cookie.

They melt SO perfectly ooey-gooey…marshmallow perfection.


Also, skillet cookies are the best. So great for a weeknight dessert or even a get-together.

Let everyone dig in with a spoon. And double dipping only counts if you get caught…so…

The batter starts with the usual suspects.

But throw in some crushed graham crackers for good measure.

Just mix them right in to your dough…

Also, milk chocolate is not optional in a s’more…so chop up some chocolate bars!

Isn’t the dough gorg?

S'mores Cookie Dough!

Layer half the dough into your skillet and top with some mini marshmallows for extra gooey-ness!

If your skillet isn’t seasoned well grease it lightly with some butter. Here’s the link to the skillet I have used for years.

Top with the remaining dough…

Cover all the marshmallows completely.


Pop that in the oven.

And while it’s baking grab your bottle of Campfire Giant Roasters.

    1. I would keep it in the fridge and then let the the dough come up to room temp before baking and it should be fine! If you bake the dough cold it will change the bake time and also, possibly how evenly it bakes 🙂

  1. Could you prepare ahead of time? Like if you wanted to make and bring to someones house, or give away. Assemble all in skillet with instructions and campfire marshmallows separate. Any thoughts?

  2. The only problem with recipes from overseas is that there is always one ingredient that I have either never seen here, or I’ve never heard of. Still, I suppose I could make do with medium sized marshmallows, if I absolutely must. Sigh, the sacrifices one makes. 🙂
