What’s better than a giant cookie made in a cast iron skillet? One that’s stuffed AND topped with your favorite s’mores ingredients! This s’mores skillet cookie is the dessert of your dreams!
Ok, so it’s always hot in South Florida so the chances of you sitting around a bon fire making s’mores is slim to none. This is the perfect way to enjoy all the deliciousness that s’mores has to offer no matter what climate and year round!
For the ingredients, we are using classic chocolate chip ingredients: flour, eggs, baking powder, sugar, butter, and vanilla extract. Then the fun twist is the s’mores ingredients: marshmallows, graham crackers, and I wanted to be fun and use the caramel filled chocolate Ghirardelli squares. You can swap the chocolate squares out for regular chocolate if you wish.
Making the chocolate chip cookie
First we are going to assemble the chocolate chip cookie part. I start with softened unsalted butter (you know my fav is kerrygold), brown sugar, and granulated sugar. You’re going to beat this with an electric mixer until it is light and fluffy.
Next, you’re going to add one whole egg and one egg yolk. I separate the egg yolk by cracking the shell in half and transferring the yolk back and forth till it rids itself of the white. You can also do this with your hands and allow the white to go through your fingers into the sink. Add the vanilla extract and mix again until the egg and vanilla are combined.
Next I added kosher salt and baking powder to the flour measurement. On the low mix setting, slowly add the flour until it’s all combined. Do not add too much at once or it will alter the consistency of the batter.
I then folded in chocolate chunks with a spatula into the batter. Once the chocolate is folded in, I divide the batter down the center into two parts.
Assembling the cookie skillet
Now comes the assembling. I used an 8 inch cast iron skillet and buttered the inside (to ensure it’s very nonstick). Take half of the cookie dough you divided and press it into the bottom of the skillet. I went about half an inch up on the sides, so it will seal all the stuffing inside (more on that in one second).
The best part, the stuffing! So I broke 4 graham crackers in half and situated them on top of the cookie dough, followed by some chocolate caramel filled squares, and mini marshmallows on top. As I said earlier, you can sub the caramel filled chocolate for regular chocolate squares.
Now, take the remaining half of cookie dough and spread it over the top of the stuffing. This is going to go into the oven for about 25-30 minutes depending on how thick your cookie is.
While the cookie is baking, I crushed up some graham crackers in a ziplock bag and chopped up some more chocolate. This is going to top the s’mores cooking towards
At the 20 minute mark, I sprinkled the rest of the marshmallows on top, chopped chocolate, and some crumbled graham crackers then finished baking it. I don’t add these toppings at the beginning because the marshmallows will burn too much if they are in for 30 minutes.
S’mores Skillet Cookie
Once the time is up, let the skillet cookie cool for 10 minutes. Cut and serve like a pie, vanilla ice cream alongside is optional but highly recommended! I hope you enjoy this delicious s’mores skillet cookie!
